STRUCTURE multi PBS Pro scripts

Submitted by vojta on Thu, 02/25/2021 - 17:24

Set of scripts to run STRUCTURE in parallel on computing grids like MetaCentrum. Scripts are designed for grids and clusters using PBS Pro, but can be easily adopted for another queue system.

Parallel Alpine Differentiation in Arabidopsis arenosa

Parallel evolution provides powerful natural experiments for studying repeatability of evolution and genomic basis of adaptation. Well-documented examples from plants are, however, still rare, as are inquiries of mechanisms driving convergence in some traits while divergence in others. Arabidopsis arenosa, a predominantly foothill species with scattered morphologically distinct alpine occurrences is a promising candidate. Yet, the hypothesis of parallelism remained untested.

Course of work with molecular data in R 2021

Submitted by vojta on Tue, 10/06/2020 - 17:08

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.

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

Previous knowledge of R is useful, but not necessary. At least basic knowledge of molecular biology is required, previous knowledge about any methods how to analyse DNA data is recommended.

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

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

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.

R is nowadays probably the most powerful tool for statistics of all types. There are plenty of modules available for work with molecular data. Those will be introduced during the course. Previous knowledge of R is useful, but not necessary. If there is at least one participant not speaking Czech, the course will be in English.
