张文利 气候变化 分子机制 作物生长
2023/10/28
随着全球气候变化的不断加剧，低温冻害和冷害已经成为影响农作物生长的一个重要自然胁迫因素。冷胁迫通常影响农作物正常的生长发育进程，严重时导致减产甚至颗粒无收。因此，作物冷应答分子机制研究可为作物耐冷分子育种提供理论参考。植物R-loop在不同的细胞活动中发挥重要作用，包括发育调控和胁迫应答等。然而，在低温敏感型作物如水稻中，R-loop介导冷胁迫应答的分子机制仍鲜有报道。

宋庆鑫 水稻栽培 基因

水稻是全球最为重要的粮食作物之一，在其漫长的驯化过程中形成了形态各异的水稻栽培亚型，包括粳稻、籼稻、Aro和Aus等。在水稻栽培种植历史过程中，有些水稻逐渐恢复部分野生稻表型特征，最终演化成严重威胁全球水稻产量的杂草稻，这种现象称之为“去驯化”。通过基因组进化研究发现，大量驯化位点的变异在去驯化过程中并不能得到恢复，这就暗示着可能存在别的遗传机制来调控杂草稻在去驯化过程中恢复野生稻表型。DNA甲基...
