生长素调控水稻生长发育的研究进展OACSTPCD

Auxin(IAA)is an important plant growth hormone that is ubiquitous in a variety of plants and algae.Auxin is involved in physiological processes such as tissue differentiation,organogenesis,morphological construction,tropism,and apical dominance.At present,the mechanism of auxin regulating growth and development in Arabidopsis thaliana dicotyledons is basically clear,but there are still many unsolved mysteries about how auxin functions in rice.In this paper,a series of biological events and physiological mechanisms of auxin regulating the growth and development of rice organs of monocots in the past two decades at home and abroad are reviewed,and the regulatory mechanism of auxin-related genes on rice organs is summarized,the precise synthesis of auxin in rice,relying on auxin pathway,and the use of auxin mutant phenotypic variation to develop plants in the future are prospected.
