摘要:

磷素是植物生长和发育所必需的大量元素之一。现在研究表明OsPHR2,OsSPX1,OsmiR399,OsPHO,OsIPS1,OsIPS2,OsSIZ1,pht1家族等基因与水稻磷吸收信号调控和磷转运有关。目前研究表明OsPHR2,OsSPX1与其在拟南芥中的同源基因功能相似,水稻超表达OsPHR2和干涉OsSPX1都有富集磷的表型。Pht1家族的大部分基因都属于高磷亲和力转运蛋白。此文概述了近年来水稻磷信号途径研究进展,并对进一步研究做了展望。

Abstract:

Phosphorus (Pi) is one of the major nutrients for higher plant growth and development. Recently studies show that OsPHR2, OsSPX1, OsmiR399, OsPHO, OsIPS1, OsIPS2, OsSIZ1 and pht1 family have been shown to be involved in the phosphate-related signal transduction and regulation pathways. OsPHR2 and OsSPX1 have the similar function with the homologous genes in Arabidopsis thaliana, overexpression of OsPHR2 and suppression of OsSPX1 are resulted in severe signs of toxicity caused by the over-accumulation of Pi. The majority of the plants PTs belong to the Pht1 family. Recent study advances of Phosphate-Signaling Pathway in rice were reviewed.
