[Construction of phylogenetic tree of plant tubulins basing on the homology of their protein sequences].
We have built phylogenetic tree of alpha-, beta- and gamma-tubulins of plant kingdom, alpha- and beta-tubulins of pig, and all epsilon- and delta-tubulins with known primary sequences and analyzed the levels of homology of tubulin sequences for repersentatives of different groups of organisms. It has been established low heterogeneity of alpha-, gamma-tubulin families and more than two fold higher heterogeneity of beta-tubulins, based on the sequence speciality of alga tubulins. We have showed that sequences of animal tubulins do not fit any cluster formed by on the plant tubulins. Presence in primary tubulin sequences of three major families of insignificant specific differences which are specific for such phylogenetic items of plant kingdom as alga and angiosperms has been also demostrated. The cladogramm shows clear clasterization of investigated sequences according to their belonging to the tubulin families.
