Rab protein is one of the largest members in the superfamily of small G protein, which widely exists in animals, plants and microorganisms. Rab acts as a molecular switch for vesicle transport and regulates the budding, transport, tethering, docking and fusion of intracellular vesicles. The Rab protein family in plants is divided into eight branches, namely RabA, RabB, RabC, RabD, RabE, RabF, RabG and RabH. Rab protein has unique structure characteristics, which determines its functional specificity. Rab proteins have certain regulatory effects on pollen tube germination, fruit maturation, root hair development and nodule formation in plants. Rab proteins also has salt and drought-tolerance in plants. Therefore, the structure of Rab protein, its involvement in plant growth and development, and abiotic stress were discussed.
