Course of work with molecular data in R 2020 in České Budějovice

Submitted by vojta on Fri, 03/06/2020 - 22:39

R is nowadays probably the most powerful tool for calculations of all kinds. There are plenty of modules available for work with molecular data. Those will be introduced during the course. Due to the Chinese COVID the course is postponed until Autumn 2020.

The course contains theory of used methods, tutorials with test data, tasks for individual work of participants, and more.

Low genetic differentiation despite high fragmentation in the endemic serpentinophyte Minuartia smejkalii (M. verna agg., Caryophyllaceae) revealed by RADSeq SNP markers

Submitted by vojta on Mon, 01/13/2020 - 10:46

Minuartia smejkalii is an obligate serpentinophyte plant endemic to the Czech Republic. Since the 1960s, the species’ habitat has undergone strong human-mediated fragmentation, resulting in extinction of some populations and dramatic size reduction of the remaining populations. Thus, contrary to the typically stable serpentine habitats, M. smejkalii habitats underwent a recent and severe decline, which can exacerbate the effects of fragmentation on population genetic structure. We examined the genetic structure of all known M.

Analysis of wild Taraxacum bicorne Dahlst. (Compositae–Crepidinae) as a potential alternative natural rubber crop

Submitted by vojta on Wed, 05/29/2019 - 14:36

Taraxacum koksaghyz Rodin, a dandelion from the steppes of south-eastern Kazakhstan, has been known for long time as potential rubber producer, as a temperate region alternative to the tropical rubber tree Hevea brasiliensis Müll. Arg.. In this work, we evaluate Taraxacum bicorne Dahlst. (wild populations), a closely related congener of T. koksaghyz.

Taxonomic principles, reproductive systems, population genetics and relationships within selected groups of genus Taraxacum (Asteraceae)

Submitted by vojta on Wed, 11/21/2018 - 16:55

Genus Taraxacum (Asteraceae), having ∼60 sections and 2,800 species, is known for its complicated evolutionary relationships and taxonomy due to processes like frequent hybridization, polyploidization, asexual reproduction, clonality and low structural morphological variability. Various taxonomical concepts and approaches are reviewed, evaluated and discussed from point of view of their ability to deal with such a complicated genera as is Taraxacum. Various processes responsible for the complicated situation within Taraxacum are discussed and reviewed. Section Dioszegia, comprising T.

Identification of oligoclonal agamospermous microspecies: taxonomic specialists versus microsatellites

Submitted by vojta on Sat, 02/20/2016 - 14:50

There has been a decrease in the ability of biologists to identify their material correctly, particu- larly plants of complicated genera with common agamospermy, where old clonal entities are accorded the rank of species (microspecies). Agamospermous microspecies are taxonomic enti- ties recognizable from one another by a set of minute morphological features. The knowledge of microspecies is confined to a few specialists. Specialists usemicrospecies names but there could be inconsistencies in the taxonomic concepts used by different, geographically remote experts.
