| 摘 要： | 开花植物的有性生殖阶段对温度胁迫高度敏感,高温热害和低温冷害都会对这一过程造成严重影响。本文全面总结了温度胁迫对作物有性生殖的影响,明确花粉发育过程是有性生殖过程中对温度胁迫最敏感的时期;转录组和蛋白质组的研究结果表明,蛋白激酶、热激转录因子、热休克蛋白等可能参与花粉发育期对热胁迫的信号转导。理解植物在有性生殖发育阶段如何适应温度胁迫的机理,为遗传育种实践中筛选对温度耐受的作物品种提供指导,也为基因工程选育对温度耐受的品种提供可能。

| Abstract: | The sexual reproduction in flowering plants is highly sensitive to hot or cold temperature stresses,thus temperature is fatal to reproductive success. This review describes studies of temperature stress on plant sexual reproductions,which suggests that pollen development may be the most sensitive reproductive stage. Transcriptome and proteomic studies shows that the genes including calmodulin,calcium dependent protein kinase 2,HSFs,and HSPs,might be involved in heat stress response pathways that function during pollen development. Understanding how plants cope with stress during reproductive development provides the oppotunity to identify genetic traits that can improve temperature tolerance in selected crop breeding and agronomic plants by genetic engineering. |
