摘要/Abstract

摘要： 水稻在生殖发育期对高温胁迫非常敏感，高温热害已经成为水稻生产最重要的限制因子之一。阐明水稻在生殖发育期耐热性的分子遗传机制，挖掘耐热关键基因，利用基因工程以及分子标记辅助选择的方法改良水稻品种的耐热性具有重要意义。从水稻生殖发育期耐热性的数量性状基因定位（QTL）、转录以及蛋白水平的高温应答、耐热转基因研究领域的进展进行了概述。

Abstract: Heat stress has become one of the most devastating factors limiting the rice production, especially at the reproductive stage. Elucidating the molecular and genetic mechanism is therefore significant for improving the heat tolerance of rice varieties by genetic engineering or maker assisted selection. In this paper, we review the research advances on heat-tolerance QTL, transcript and protein response to heat stress, and genetic engineering for heat tolerance in rice.

Key words: rice, reproductive stage, heat tolerance, molecular and genetic mechanism
