Course of work with molecular data in R 2023

Submitted by vojta on Wed, 10/12/2022 - 10:16

R is nowadays probably the most powerful tool for calculations of all kinds. There are plenty of modules available for work with molecular data. Their representative selection 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. The aim is to teach students how to analyze molecular data in R programming language, introduce available packages for their analysis and practical trying out to work with own or provided data.

Relative performance of customized and universal probe sets in target enrichment: A case study in subtribe Malinae

Submitted by vojta on Mon, 07/26/2021 - 12:46

Custom probe design for target enrichment in phylogenetics is tedious and often hinders broader phylogenetic synthesis. The universal angiosperm probe set Angiosperms353 may be the solution. Here, we test the relative performance of Angiosperms353 on the Rosaceae subtribe Malinae in comparison with custom probes that we specifically designed for this clade. We then address the impact of bioinformatically altering the performance of Angiosperms353 by replacing the original probe sequences with orthologs extracted from the Malus domestica genome.

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.
