AB  - Pinus peuce (Macedonian pine) is considered a valuable ornamental tree that is frequently planted in parks and gardens, especially in Western Europe. This endemic pine is one of the most valuable conifer species in its native range, which currently consists of only two disjunct populations restricted to small mountainous areas of the Balkans and is listed as a near-threatened species. The reproduction of Macedonian pine by seed is limited, so in vitro propagation methods have emerged as a promising tool for large-scale propagation. The objective of this study was to develop an improved system for the micropropagation of P. peuce from juvenile plant material using a short-term liquid cytokinin pulse. For that, explants derived from 4-week-old seedlings were pulse-treated with different concentrations of N6-benzyladenine (BA) for 1 or 2 h to stimulate the induction of axillary buds. The highest axillary shoot formation was achieved with 222 µM BA pulse treatment, with an average number of ~six shoots per explant. Elongated shoots (≥10 mm) were detached from the explants and pulse-treated with 0.27 or 1.08 mM α-naphthaleneacetic acid (NAA) or 0.25 or 0.98 mM indole-3-butyric acid (IBA) for 1 or 2 h. IBA was more effective than NAA and led to a maximum rooting percentage (up to 40%) and the highest number of acclimatized plants (15–20%). Rooted plants were successfully transferred to ex vitro conditions.

AB  - Clinopodium pulegium (Rochel) Bräuchler (Lamiaceae) is an endangered species endemic to the Southern Carpathians. It is characterized by the production of high amounts of essential oils, which emit volatile organic compounds (VOCs) that have an essential role in biotic and abiotic stress responses and in plant-plant and plant-insect interactions. The present study was initiated to phytochemically examine the influence of different carbon sources in the nutrition medium on VOC emissions of micropropagated C. pulegium plants, using gas chromatography-mass spectrometry analysis of headspace VOCs. The volatile profiles were subjected to multivariate analysis with respect to the presence, concentration and type of carbon source in the nutrient medium. In addition, the effect of different carbohydrates on the density and size of the leaf glandular trichomes, the main structures involved in the emission of VOCs, was determined. A total of 19 VOCs, primarily belonging to mono- and sesquiterpenes previously described in plants, were tentatively identified. Six VOCs were produced at levels higher than 2% of the total VOC emission, dominated by pulegone, ß-pinene and menthone. Inclusion of the carbohydrates in the culture media affected the production of the main leaf trichome-associated volatile allelochemicals although the qualitative composition of the volatiles changed only slightly. Multivariate analysis showed that the concentration, rather than the carbohydrate type, influenced the VOC profile.

plants due to the presence of glandular trichomes, which have a distinct ability
to synthesize, secrete or store large amounts of specialized metabolites that
play a crucial role in mediating the plant–environment interactions. These

AB  - Clinopodium thymifolium (Scop.) Kuntze (syn. Micromeria thymifolia (Scop.) Fritsch) is a Balkan endemic species, traditionally used as a condiment and medicinal plant in the Mediterranean area. Clinopodium species were shown to produce considerable quantities (> 0.5%) of essential oils. The essential oil of wild-growing C. thymifolium possesses high antimicrobial activity. One alternative for the production of commercially important plant-derived metabolites, especially of rare plant genotypes, is in vitro plant tissue culture, given that the metabolic potential of in vitro shoot cultures can be manipulated by varying in vitro culture conditions. In view of the potential pharmacological and commercial value of C. thymifolium, the present study was initiated to propagate this aromatic plant species with the aim to increase the accumulation of biomass and the production of secondary metabolites. Shoots of wild-growing plants, dissected into one-node stem segments bearing two axillary buds, were used to establish in vitro cultures. Shoot multiplication was carried out on basal nutritional medium and on medium supplemented with various plant growth regulators at different concentrations. Nodal segments developed axillary shoots, and were successfully propagated on basal medium, whereas tested plant growth regulators differently affected their multiplication and biomass production.

The glandular indumentum was studied by means of light microscopy and scanning electron microscopy in an attempt to correlate the phytochemical traits with the glandular trichome morphotypes of selected Lamiaceae species.",

AB  - Glandular trichomes found on the surface of many higher plants contain specialized cells that produce and secrete copious amounts of particular secretory products. Leaf glandular trichomes of the non-model plant species Nicotiana tabacum represent a biologically active and stress-responsive tissue that contributes to plant defense response against biotic and abiotic stress and also influences leaf aroma and smoke flavor. Two morphologically different types of tobacco capitate trichomes, long- and short-stalked, with distinct functions, display ultrastructural features that are common to terpene-secreting glands, but only the secretory cells of the tall glandular trichomes are considered to be the site of biosynthesis of certain exudate compounds, including diterpenes and sucrose esters. Ultrastructural and histochemical characterization of tall glandular trichomes is described in an attempt to understand the contribution of these glands to the total secretion produced. Possible roles of distinct cellular compartments involved in the secretory process and secondary metabolite secretion under in vitro conditions are discussed.

AB  - MAIN CONCLUSION In vitro culture conditions and kinetin induced quantitative modifications in the production of the major volatile constituents in Micromeria croatica plantlets. Antimicrobial activity of methanolic extracts obtained from micropropagated and wild-growing plants was evaluated. Micromeria spp. are aromatic plants, many of which were shown to exhibit various biological effects. The present study aimed to determine the content and the composition of the essential oil of in vitro-cultured Micromeria croatica (Pers.) Schott and to evaluate the in vitro antimicrobial activity of its methanolic extract, in order to compare its phytochemical profile and biological activity with wild-growing plants. Shoots regenerated on MS medium without plant growth regulators (PGRs) or supplemented with kinetin were used for phytochemical analysis. Essential oils from both native plant material and in vitro-cultivated M. croatica plants, with a total of 44 identified constituents, were dominated by oxygenated monoterpenes. Borneol was the main component detected in wild-growing plants (25.28%) and micropropagated plants grown on PGR-free medium (20.30%). Kinetin treatment led to increased oil yield and favored the production of oxygenated monoterpenes, dominated by geranial (33.53%) and cis-p-mentha-1(7),8-dien-ol (23.69%). The percentage of total sesquiterpenoids in micropropagated plant material was considerably lower than in wild-growing plants. In vitro culture conditions and PGRs affected the production of essential oils, inducing quantitative modifications in the production of the major volatile constituents in M. croatica plantlets. The antimicrobial activity of M. croatica methanolic extracts was investigated using the broth microdilution method. Extracts obtained from in vitro cultures generally exhibited greater antibacterial potential, compared to wild-growing plants. Among six bacterial strains tested, Bacillus cereus and Staphylococcus aureus were the most sensitive microorganisms. The present study provided evidence that in vitro culture conditions might favorably affect the antimicrobial activity of M. croatica methanolic extracts.

AB  - Morphology and structure of Micromeria croatica glandular trichomes in relation to the secretory process were characterized using scanning electron microscopy (SEM) and light microscopy, and their secretion was histochemically analyzed. SEM and histochemical analysis revealed that leaf indumentum of in vitro grown M. croatica consisted of non-glandular and glandular trichomes (Figure 1a). The main types of glandular trichomes observed in M. croatica leaves were peltate and capitate (Figure 1b-d). Peltate trichomes consisted of a broad basal cell embedded in the epidermis, a single-celled stalk, and a large round multicellular head (Figure 1e, h). Two types of capitate trichomes, differing in size and structure, could be distinguished. Type I capitate trichomes were positioned at an angle to the leaf surface and composed of one basal epidermal cell, short cutinized stalk and unicellular ellipsoidal head (Figure 1f). Type II capitate trichomes comprised of one basal cell, unicellular stalk and one apical secretory cell (Figure 1g). Apical cell of mature type II capitate trichomes had well developed round subcuticular space (Figure 1d). Plant extracts secreted from glandular trichomes are a valuable source of biologically active compounds. Phytochemical analysis identified up to 37 compounds in the essential oils (EOs) of wild-growing and micropropagated plants, and revealed differences in both content and the composition of the EOs obtained from different samples. EOs from both native plant material and in vitro cultivated plants showed very high percentages of total monoterpenoids, dominated by oxygenated monoterpenes. 
Borneol was the main essential oil component detected in wild-growing plants (25.28%) and micropropagated plants grown on plant growth regulator-free medium (20.30%). Micropropagated plants cultivated in the presence of 0.3 µM kinetin had the highest yield of the EO, with geranial (33.53%) and cis-p-mentha-1(7),8-dien-ol (23.69%) being the main EO components. The percentage of total sesquiterpenoids in micropropagated plant material was considerably lower than in wild-growing plants. Sesquiterpene hydrocarbons accounted for the majority of detected sesquiterpenoids and were dominated by alpha-cadinene and beta-vetivenene. Some of the volatiles were found only in plant material obtained by micropropagation but not in wild-growing plants. Differences in both content and the composition of the essential oils obtained from different samples indicated that in vitro culture conditions and plant growth regulators significantly influence the essential oils properties.

AB  - The anatomy and ultrastructure of the short glandular trichomes occurring on young expanding leaves of Nicotiana tabacum were investigated using light and transmission electron microscopy. The objective of the present research was to characterize the cellular changes that occur during morphogenesis of short glandular trichomes, from initiation to senescence. Ultrastructural analysis of their secretory cells revealed characteristics common to gland cells: numerous mitochondria in highly organized cytoplasm, large nuclei, and an elaborate network of endoplasmic reticulum. Initial changes in nuclear and plastidial organization were observed at a more advanced secretory stage, marking the onset of senescence. During trichome senescence, gradual reduction of the cytoplasm density occurred along with structural changes of the plastids and the tonoplast. As a result of inward blebbing of the cytoplasm into the vacuole, membrane bound vesicular structures appeared in the vacuolar space. At the late secretory stage, marked by an increase in vacuolation and extraplasmic space, degenerative changes included further fragmentation of the cytoplasm and deterioration of the tonoplast. Multimembrane myelin bodies observed in the vacuolar space were indicative of membrane digestion although plasma membrane did not appear massively degraded.

The objective of the present research was to characterize the cellular changes that occur during morphogenesis of short glandular trichomes, from initiation to senescence. Ultrastructural analysis of their secretory cells revealed characteristics common to gland cells: numerous mitochondria in highly organized cytoplasm, large nuclei, and an elaborate network of endoplasmic reticulum. Initial changes in nuclear and plastidial organization were observed at a more advanced secretory stage, marking the onset of senescence. During trichome senescence, gradual reduction of the cytoplasm density occurred along with structural changes of the plastids and the tonoplast. As a result of inward blebbing of the cytoplasm into the vacuole, membrane bound vesicular structures appeared in the vacuolar space. At the late secretory stage, marked by an increase in vacuolation and extraplasmic space, degenerative changes included further fragmentation of the cytoplasm and deterioration of the tonoplast. Multimembrane myelin bodies observed in the vacuolar space were indicative of membrane digestion although plasma membrane did not appear massively degraded.",

AB  - The content and chemical composition of Micromeria
pulegium (Rochel) Benth. essential oils were studied in
native plant material at vegetative stage and in micropropagated
plants, obtained from nodal segments cultured
on solid MS medium supplemented with N6–benzyladenine
(BA) or kinetin at different concentrations, alone or in
combination with indole-3-acetic acid. Shoot proliferation
was achieved in all treatments, but the highest biomass
production was obtained after treatment with 10 μM BA.
Phytochemical analysis identified up to 21 compounds in
the essential oils of wild-growing and in vitro cultivated
plants, both showing very high percentages of total
monoterpenoids dominated by oxygenated monoterpenes
of the menthane type. Pulegone and menthone were the
main essential oil components detected in both wildgrowing
plants (60.07 and 26.85 %, respectively) and
micropropagated plants grown on either plant growth regulator-
free medium (44.57 and 29.14 %, respectively) or
BA-supplemented medium (50.77 and 14.45 %, respectively).
The percentage of total sesquiterpenoids increased
in vitro, particularly owing to sesquiterpene hydrocarbons
that were not found in wild-growing plants. Differences in
both content and the composition of the essential oils
obtained from different samples indicated that in vitro
culture conditions and plant growth regulators significantly
influence the essential oils properties. In addition, the
morphology and structure of M. pulegium glandular trichomes
in relation to the secretory process were characterized
for the first time using SEM and light microscopy,
and their secretion was histochemically analyzed.

AB  - The tall glandular trichomes occurring on young expanding leaves of Nicotiana tabacum grown in
vitro were investigated using light and electron microscopy. Previous studies reported that the tall
glandular trichomes of tobacco produce large quantities of various compounds including diterpenes.
To explore the cellular structures required and putatively involved in diterpene biosynthesis and
secretion, the present study focused on the development of the tall glandular trichomes, and on
histochemical and ultrastructural analysis of their secretory cells under in vitro conditions. Electron
microscopy confirmed earlier light microscopy observations of the glandular nature of the tall leaf
trichomes. Their head cells, which secrete resinous material, exhibited characteristics common
to gland cells: a dense cytoplasm, numerous mitochondria and little vacuolation. They contained
structurally well-developed chloroplasts and an elaborate network of endoplasmic reticulum, as
well as electron dense inclusions in chloroplasts and in small vacuoles. The dominance of smooth
endoplasmic reticulum suggests its involvement in diterpene biosynthesis. Histochemical tests were
positive for both lipophilic and hydrophilic secretions, which included terpenoids (essential oils
and resins) and acidic/neutral lipids, as well as phenolic compounds (tannins), alkaloids, mucilage/
pectin and polysaccharides.

AB  - The effects of nutritional, hormonal, and physical factors on the germination and growth of isolated mature zygotic embryos of Pinus heldreichii were studied under in vitro conditions. The optimum medium for embryo germination and adequate conversion into seedlings was basal Gresshoff and Doy (1GD) medium. All tested carbohydrates at the applied concentrations stimulated embryo growth, but only 3% sucrose increased embryo germination compared to the control, while maltose had an inhibitory effect. Among the applied plant growth regulators, only gibberelic acid (GA3) had a few benefits on the development of isolated embryos into plantlets, while the others had a negative effect. Embryos cultured on an agar-solidified medium grew better and the germination percentage was higher than in a liquid medium. Light treatment did not affect embryo germination, but generally stimulated seedling growth.
AB  - U kulturi in vitro ispitivan je efekat nutritivnih, hormonalnih i fizičkih faktora na klijanje i rastenje izolovanih zigotskih embriona munike (Pinus heldrechii). Većina izolovanih embriona munike klijala je već tokom prve nedelje nakon prenošenja na hranljivu podlogu. Mada embrioni mogu da klijaju i na podlozi bez soli, vitamina i ugljenih hidrata, najveći procenat klijanja i najbolje morfološke karakteristike klijanaca postignute su na bazalnoj Gresshoff & Doy podlozi (1GD) sa 3% saharozom. Od ispitivanih regulatora rastenja samo je giberelna kiselina (GA3) pozitivno delovala na razviće embriona, dok su auksini i citokinini inhibirali njihovo dalje razviće. U odnosu na embrione koji su rasli u tečnoj podlozi, embrioni sa čvrste agarne podloge, klijali su u većem procentu i dalje se pravilno razvijali. Mada generalno stimulišu rastenje klijanaca, svetlosni tretmani nisu imali efekat na klijanje embriona. Dobijeni rezultati pokazuju da se in vitro sistem može koristiti za brzu i sinhronu produkciju zdravih klijanaca elitnih genotipova koji se odlikuju niskom produkcijom semena.

abstract = "The effects of nutritional, hormonal, and physical factors on the germination and growth of isolated mature zygotic embryos of Pinus heldreichii were studied under in vitro conditions. The optimum medium for embryo germination and adequate conversion into seedlings was basal Gresshoff and Doy (1GD) medium. All tested carbohydrates at the applied concentrations stimulated embryo growth, but only 3% sucrose increased embryo germination compared to the control, while maltose had an inhibitory effect. Among the applied plant growth regulators, only gibberelic acid (GA3) had a few benefits on the development of isolated embryos into plantlets, while the others had a negative effect. Embryos cultured on an agar-solidified medium grew better and the germination percentage was higher than in a liquid medium. Light treatment did not affect embryo germination, but generally stimulated seedling growth., U kulturi in vitro ispitivan je efekat nutritivnih, hormonalnih i fizičkih faktora na klijanje i rastenje izolovanih zigotskih embriona munike (Pinus heldrechii). Većina izolovanih embriona munike klijala je već tokom prve nedelje nakon prenošenja na hranljivu podlogu. Mada embrioni mogu da klijaju i na podlozi bez soli, vitamina i ugljenih hidrata, najveći procenat klijanja i najbolje morfološke karakteristike klijanaca postignute su na bazalnoj Gresshoff & Doy podlozi (1GD) sa 3% saharozom. Od ispitivanih regulatora rastenja samo je giberelna kiselina (GA3) pozitivno delovala na razviće embriona, dok su auksini i citokinini inhibirali njihovo dalje razviće. U odnosu na embrione koji su rasli u tečnoj podlozi, embrioni sa čvrste agarne podloge, klijali su u većem procentu i dalje se pravilno razvijali. Mada generalno stimulišu rastenje klijanaca, svetlosni tretmani nisu imali efekat na klijanje embriona. Dobijeni rezultati pokazuju da se in vitro sistem može koristiti za brzu i sinhronu produkciju zdravih klijanaca elitnih genotipova koji se odlikuju niskom produkcijom semena.",

AB  - The potential for somatic embryogenesis in zygotic embryo and megagametophyte cultures of Pinus heldreichii was examined. Somatic embryogenesis was initiated from megagametophytes containing immature zygotic embryos at early stages of development. An induction frequency of up to 6.7% was obtained on Gresshoff and Doy medium in the presence of 2 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.5 mg/l benzyladenine (BA). Formation and further proliferation of embryogenic tissue were achieved upon transfer of explants to a medium with reduced levels of growth regulators. Somatic embryos are being cultured for further development. .
AB  - U kulturi izolovanih zigotskih embriona i ovula munike (Pinus heldreichii) ispitivan je efekat hranljive podloge i regulatora rastenja na indukciju somatske embriogeneze. Somatska embriogeneza je indukovana u kulturi ovula koje su sadržavale embrione na ranom stupnju razvića. Najviša frekvencija indukcije od 6.7% postignuta je kada su ovule 5 dana gajene na Gresshoff i Doy (GD) hranljivoj podlozi u prisustvu 2,4-D 2 mg/l i BA 0.5 mg/l, a zatim prenete na GD podlogu u kojoj je koncentracija regulatora rastenja bila 5 puta niža. U cilju dugotrajnog održavanja u kulturi, embriogeno tkivo je izolovano i gajeno na GD podlozi sa 2,4-D 0.2 mg/l i BA 0.05 mg/l. Mikroskopskom analizom je utvrđeno da se tkivo sastoji od brojnih embriona na ranim stupnjevima razvića. Za klonalnu propagaciju ove značajne endemoreliktne četinarske vrste u kulturi in vitro, neophodna su dalja istraživanja sa ciljem povećanja frekvencije indukcije somatske embriogeneze, kao i frekvencije sazrevanja embriona. .
