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

Tagy: 

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)

Tagy: 

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.

Course of work with molecular data in R 2019

Tagy: 

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.

Course of work in Linux command line not only for MetaCentrum 2019

Don’t be afraid of command line! It is friendly and powerful tool. Practically identical is command line also in Apple osX, BSD and another UNIX-based systems, not only in Linux. Basic knowledge of Linux is not conditional. Course will be taught in Linux, but most of the point are applicable also for another UNIX systems like osX. Knowledge of Linux/UNIX is useful e.g. for working with molecular and another data. MetaCentrum is service provided by CESNET allowing access to huge computational capacity.

Crisis 1938

This year we can remind plenty of "eighth" anniversaries, including year 1938. Czechoslovakia was target of operation we use to call a hybrid war nowadays. Aggressor was not Putin's Russia, which is nowadays more (Ukraine, Georgia, Moldova, ...) or less (EU, North America) systematically destabilizing states, where it has power ambitions. That time aggressor was Hitler's Germany, which (similarly to contemporary Russia) misused its minorities in countries of central and eastern Europe to their destabilization and conquest.
