AB  - The toxicity of bipyridynium herbicide paraquat (PQ) is related to its rapid generation of superoxide in a chain reaction and the production of reactive oxygen species (ROS) in chloroplasts under light conditions. The nature and magnitude of the cellular responses to oxidative stress effects of five paraquat concentrations (0.05-20 μM) on in vitro grown Nepeta panonnica shoots were investigated. The results revealed that relative abundances of Mn SOD and Cu/Zn SOD isoforms changed dose-dependently, whereas catalase (CAT) and peroxidase (POX) activities increased along with paraquat concentrations. Polyphenol oxidase (PPO) activity was progressively inhibited, and, consequently, phenolic compounds were accumulated. Rosmarinic acid (RA) and an unidentified caffeic acid derivative (UCAD) were found to be the most abundant phenolics in shoots of this species. Paraquat was shown to be a potent elicitor that can stimulate accumulation of potent bioactive compounds in Nepeta pannonica, such is rosmarinic acid.

AB  - The non-selective herbicide Paraquat has been used worldwide since 1960 and remains an important herbicide for broad-spectrum weed control. lt exhibits toxicity toward aerobically-grown cells via the produc­tion of superoxide and (indirectly) other active oxygen species. Studies demonstrate that Paraquat-mediated active oxygen stress elicits a cellular response that involves induction of active-oxygen scavenging enzymes, particularly superoxide-dismutase (SOD), catalase (CAT) and other defensive responses, including DNA repair. The present study is an exploration of the nature and magnitude of the cellular responses to Paraquat-mediated oxidative-stress in Nepeta pannonica L. shoot cultures, with special attention to SOD activity and isozyme pro­file. Plants were exposed to different concentrations of Paraquat (0.05-20 µmol), and dose-dependent chang­es in SOD activity and enzyme relative abundance were recorded. Paraquat was found to be a potent inducer of total SOD activity. This herbicide also influences the relative abundance of Cu-ZnSOD and FeSOD isoforms. MnSOD isoforms were not recorded in N. pannonica. Results show that other enzymes, such are peroxidases (POX) and polyphenol oxidase (PPO) also contribute to Paraquat-induced stress response in this species. Phy­tochemical characterization of N. pannonica shoots grown in vitro revealed that phenolics concentration also alternate in response to paraquat concentration. Rosmarinic acid and its glycoside are found to be the most abundant phenolic acids in this species.

AB  - In plants, catalase (CAT) is considered to play a key role in protection and repair systems during seed ageing. The aim of our study was to investigate the effects of light, GA3, KN03 and liquid smoke on germina­tion, CAT activity and CAT isozyme pattern of positive photoblastic Empress tree (Paulownia tomentosa Steud.) seeds of different ages. Freshly harvested Empress tree seeds require long term periods of light for germination. However, the applica­tion of KN03 and liquid smoke extract could stimulate germination and overcome the light requirement. Dur­ing the process of after-ripening in young seeds, their sensitivity to light in creases and a single 5 min pulse of red light is sufficient to induce maximum germination. Over longer seed storage, seeds lose ability to germi­nate and become less viable. No germination was detected in seeds older than 8 years. We observed a correlation between the level of germination and catalase activity. lts activity is higher in ma­ture seeds then in freshly harvested seeds during light-induced germination. In young seeds, CAT activity is enhanced by exogenous seed germination stimulators application. In very old, non viable seeds, CAT activity is reduced to basal level (CAT activity of dry seeds). Different CAT isozyme patterns were observed in dark- and light germinated seeds.

AB  - Allelopathy, the chemical mechanism of plant interference, was detected in many plants from fam. Lamiaceae, including Nepeta species. The majority of Nepeta species are characterized by the presence of ne­petalactone as the dominant component in essential oils. This monoterpenoid lactone exists in the form of one or more stereoisomers, and corresponding enantiomers. The present study investigates the allelopathic potential of Nepeta rtanjensís Diklić & Milojević and Nepeta ca­taria L. essential oils which differ in their qualitative nepetalactone content, on the seed germination of four selected crop species (Lepidium sativum L., Lactuca sativa L. cv. Majska Kraljica, Lotus corniculatus L., cv. Bokor and Brassica napus L. cv. napus). GC-MS analysis revealed that trans,cis- stereoisomer of nepetalactone is dom­inant in essential oil of N. rtanjensis (72,03%). Essential oil of N. cataria used in the present study is character­ized by the high content of cís, trans-nepetalactone (90%). Both essential oils exhibited significant allelopath­ic potential against all model species, with N. rtanjensís essential oil being more efficient. These results sug­gest that nepetalactone stereochemistry significantly determines its allelopathic potential, and that the ef­fect of both nepetalactone stereoisomers is dose-dependent. Essential oils reduced seed germination by in­fluencing germination dynamics, or by irreversibly inhibiting the germination of seeds. Among tested crops, L. sativa was shown to be the most sensitive to allelopathic potential of N. rtanjensis and N. cataria essential oils, while B. napus was the most tolerant.

AB  - The content of secoiridoid glycosides in the aerial parts and roots of in vitro grown centaury (Centaurium etythraea Rafn) plants, originating from 52 Balkan Peninsula populations was analyzed. The results of this study give insight into the infraspecific variability of centaury, based on the yield of secoiridoid glycosides as chemical markers of phenotypic variation. According to the cluster analysis, existence of two basic chemotypes is suggested. Moreover, the impact of prevailing environmental gradients in natural habitats on chemotype differentiation was assessed. The precipitation rate of the warmest quarter of year significantly affects the accumulation of secondary metabolites. These results will enable the selection of particular populations which are characterized by enhanced accumulation of secondary metabolites of interest, thus making it possible to realize the commercial field cultivation and upscale production and of this threatened and pharmacologically important species.

AB  - Rhodobryum ontariense (Kindb.) Kindb. (Bryaceae, Bryophyta) is a rare moss, only recently discovered in Serbia (at Deliblatska Sands). After a revision of the genus Rhodobryum in Serbia, it was concluded that all high-mountain records belong to R. roseum, while R. ontariense is confined to the one known locality at Deliblatska Sands. It is listed in the bryophyte red-list of Serbia and Montenegro. Within the single known locality we have counted 15 small sub-populations over a total surface area of 6 hectares. The species is always in sterile condition and has been recorded only on dunes exposed to the north, at the edge of shrub-grassland transition interspersed with fragments of steppe vegetation. No propagules are known. This raised the question of whether the population was once continuous, or whether vectors exist that spread detached plants or fragments to establish new subpopulations. To answer this question an isozyme analysis was performed to estimate the genetic structure of this isolated population. Based on the isozyme forms of superoxide dismutase and peroxidase at least six haplotypes were determined within the population. It can be concluded that the present patches of the moss do not derive from one subpopulation. Some kind of short-distance dispersal exists, but it remains unclear what structures act as propagules and what is the vector for them.
