水稻起源于热带和亚热带，对低温十分敏感，当温度低于15℃时水稻便无法正常生长。有统计显示，每年低温冷害导致我国水稻减产约50亿kg。近年来，因直播稻大面积推广以及水稻种植区域不断由热带、亚热带向高海拔、高纬度地区扩张，水稻遭受低温冷害的频率有增加趋势。低温冷害已成为限制我国水稻生产的一大瓶颈。因此，挖掘调控水稻耐冷性的关键基因，研究其作用机理，对防控水稻低温冷害具有重要意义。

Genome-wide identification of NF-YA gene family in cotton and the positive role of GhNF-YA10 and GhNF-YA23 in salt tolerance
全基因组分析 雷蒙德氏棉 亚洲棉 海岛棉 陆地棉

本研究基于全基因组分析，在雷蒙德氏棉、亚洲棉、海岛棉和陆地棉基因组中分别鉴定得到16、16、31和29个NF-YA基因。通过进化树分析将NF-YA基因分为4个亚组。结构分析表明NF-YA基因在棉属进化过程中相对保守。荧光定量显示GhNF-YAs可能通过ABA和 MeJA的调控通路响应盐和干旱。VIGS沉默GhNF-YA10和GhNF-YA23的表达，能显著降低棉花对盐的抗性，表明这两个基...
