Our group in the Department of Plant Cytology and Embryology of the Jagiellonian University (Cracow, Poland) in national and international cooperations uses violets as a model in long-term research. Why the genus Viola L. was chosen as a test model? Because of a few reasons: the genus comprises ca. 600 species (mainly polyploids) distributed on both hemispheres, including endemic, threatened species, taxa resistant to high concentrations of heavy metals in the soil (metallophytes, pseudometallophytes), and biosynthesizing secondary metabolites important for medical purposes.
The research focused on topics: 1) microevolutionary processes and speciation (genetic diversity, hybridization, impact of polluted environment, adaptations, genome alteration, reproduction); 2) the usefulness of floral and embryological traits in Viola taxonomy; 3) self- and cross-pollination systems (chasmogamous and cleistogamous flowers, nyctinastic flower movement); 4) ex situ conservation of endangered species with the use of in vitro culture and cryopreservation (somaclonal variation as a source of genetic differentiation of micropropagated plants); 5) selection of cell lines in suspension tolerant to high concentration of heavy metals applied to the medium (metal accumulation in cell mass and in cell structures, regeneration of plants from the most resistant cells for recultivation purposes); 6) identification of cyclic peptides (cyclotides, having properties important for medicine) in plant organs (stem, leaf, root), in callus tissue and suspended cells, their deposition in plant tissues and in cell organelles. The extensive issues includes basic and application research.
