- Аннотация: Auxin is an important inductor of organogenesis. During leaf development, local sites with high auxin concentration initiate the formation of leaf primordia and venation, control the growth of lamina and lamina margin development. The proliferative activity of the leaf cells of the Arabidopsis thaliana taeniata (tae) mutant and the role of auxin in the development of the ectopic secondary margins and lobes on the leaf of the mutant were analyzed in the study. It has been established that, in addition to the ability for ectopic proliferation of leaf cells, the tae mutant demonstrates a complex of traits characteristic of plants with impaired auxin transport. It was shown that a mutation in the PID gene, which disrupts the polar auxin transport, causes the suppression of ectopic outgrowths on the leaf of the tae mutant. These data indicate the important role of auxin transport in maintaining the leaf cell pluripotency and the development of lobes on the leaf of the tae mutant.
