quantum speciation; lilium bosniacum

Sažetak
Quantum speciation is a type of geographoical speciation in which a population "buds off" from ancestral population and becomes adapted to a diffrent habitat. While gradual process of geographical speciation ends up with two sister species, quantum speciation is radical and rapidly results in progenitor and derivative species. To fully understand this process, it is important to discover P and D populations in early stages of divergence. population level approach can provide information about early biological events in continuum of speciation, which will become invisible over time. A population of endemic Lilium bosniacum was found on serpentine soil, a factor known to govern rapid divergence and maintain derivative species. Cooperative morphological, karyological, genetic, epigenetic and glycomic analysis were conducted on lily plants from serpentine (putative derivative) and non- serpentine (putative progenitor) population. Rearangments of rDNA loci, indicative of rapid chromosome evolution, and morphologies characteristic for serpentinophytes were observed in serpentine lily plants. Also, serpentine and non-serpentine populations differed in DNA methylation profiles and N- glycom composition, reflecting changes in gene expression patterns and protein function, in absence of genetic differentiation. The data obtained suggests P-D situation on the population level, governed by adaptation to specific eco-geographical conditions.
