Superfamily of monomeric GTP-binding proteins in plants: 1. Role of rop proteins in the control of plant growth and development

Lectures

Abstract

The control of plant growth, differentiation, and development is considered in relation to the involvement of monomeric GTP-binding proteins (mG-proteins) in the extra-and intracellular signal transduction. The principal attention is paid to Rop mG-proteins, unique small GTPases of eukaryotic cells functioning during various developmental stages of plants, from pollen tube and root hair growth to plant responses to biotic and abiotic stresses.

Key words
