Arabidopsis himalaica (Edgeworth) O.E. Schulz, a poorly characterized species typical of HimalayanArabidopsis, was analyzed in terms of its morphology, physiology, chromosome number and molecular genetics, in comparison withA. thaliana which is the standard species in the genusArabidopsis. From view point of developmental genetics, several features which are specific toA. himalaica seem not to be derived by single-gene mutations inA. thaliana. Phylogenetic analyses based onrbcL sequences suggested that genusArabidopsis is not monophyletic. The detailed characterization ofA. himalaica should provide clues to understand the trait of evolution of particular features of Himalayan species ofArabidopsis and their genetic basis.
