The genus Centaurium Hill (fam. Gentianaceae) comprises about 25 annual or
biannual species of the Mediterranean origin possessing widely recognized
bioactive properties. Five species of this genus are represented within the flora
of the Balkan Peninsula: Centaurium erythraea Rafn, C. littorale (Turner)
Gilmour, C. tenuiflorum (Hoffmanns. & Link) Fritsch, C. pulchellum (Sw.)
Druce, and C. maritimum (L.) Fritsch. Decades of research on the Centaurium
species within the Institute for Biological Research “Siniša Stanković” -
National Institute of the Republic of Serbia, has resulted in the establishment
of ex situ seed collection, which fully represents the biodiversity of this genus
in the Balkan Peninsula. In addition to accepted taxa with diploid or polyploid
genomes, homoploid and allopolyploid hybrids of different origin are stored
within the ex situ collection, which contains totally 153 accessions. This
valuable source of plant material has facilitated resolving the complex
phylogenetic relationships within the Centaurium genus by adopting
morphological, molecular (EST-SSR, trnL-F, TRAP, etc.) and chemical
markers with high discrimination resolution within taxa. Furthermore, it
enabled studying the interplay between ecological and evolutionary processes
(e.g. interspecific hybridization, polyploidization, habitat fragmentation,
genetic drift), and their effects on the biodiversity of Centaurium taxa (both
genetic and chemical). By adopting multi-omics approach we study
secoiridoid glucosides metabolism and its relationship to the overall plant
physiology, as well as its role in plant-biotic and plant-abiotic interactions.
The multidisciplinary approach of our studies provided an insight into the
molecular background and regulatory networks of constitutive secoiridoids’
biosynthesis in Centaurium taxa as influenced by environmental factors, while
resolving their complex multi-level diversity at inter- and intra-species, as well
as at intra-species level. Through the implementation of biotechnology tools,our intention is to provide sustainable sources of valuable secoiridoids in
homologous or heterologous systems.
