摘要

Contrary to literature dataArabidopsis thalianawas rarely observed in Middle Asia during a collection trip in 2001. Instead, three other Brassicaceae species were frequently found at places whereA. thalianawas expected. To reveal reasons for this frequency pattern, we studied chromosome numbers, genome sizes, phylogenetic relationships, developmental rates, and reproductive success ofA. thaliana, Olimarabidopsis pumila, Arabis montbretiana, andArabis auriculatafrom Uzbekistan in two temperature treatments. There are little but partially significant differences between phenotypes. All studied species have very small genomes. The 1Cx-values of different genotypes within the sampled species are correlated with altitude. Developmental rates are also correlated with 1Cx-values. In our growth experiments,Arabidopsishad high seed sterility at higher temperature, which might be one reason for the rarity ofA. thalianain Middle Asia.
