Abstract

Rice root is the main organ for nutrient and water absorption, its growth and development are regulated by several plant hormones collaboratively. Of which,auxin is the extensively studied. In this paper, the author elucidate the development process and molecular mechanism of rice root architecture by analyzing the regulating genes that have been cloned. Comprehensive analysis reveals that the root shape is altered by auxin biosynthesis genes that regulate auxin concentration. Auxin transport regulate the development of lateral root and crown root through controlling auxin influx and efflux. Auxin signal transduction, which affects the root system, is regulated by TIR1、Aux/IAA and ARF. Besides the distrubition of auxin is influenced by acting with other plant hormones. However,these cloned root shape genes in rice is still insufficient, and the outline of molecular regulation network of auxin is not clear. Therefore,it is important to further understand molecular mechanism of auxin in rice root by screening and collecting rice auxin mutants with root mutations.
