低温作为主要的非生物逆境之一,严重影响作物的生长发育和产量。研究表明植物对低温胁迫的适应和耐受涉及到复杂的感知、信号转导和胁迫反应机制,多种激素在此过程中扮演了重要角色,然而不同激素之间如何协同调控作物耐冷性还有待深入研究。小麦作为全球主要口粮作物之一,在生产上,极端低温造成的冻害是制约小麦产量的重要因素。因此,挖掘小麦耐冷性关键基因,解析小麦耐冷性的分子机制,对于提高作物适应极端温度环境,保障国...

喜马拉雅旱獭(Himalayan marmots)是仅分布于青藏高原区域啮齿类动物,在冬季低温食物缺乏季节,它们在每年9-10月进入洞穴冬眠,在次年3月左右恢复活动。在冬眠期消耗体内的脂肪维持基础代谢,因此需要活动期快速增肥,积累足够脂肪。但其生活的环境中,食物季节性变化非常大,与脂肪代谢有关的肝脏是如何适应快速积累脂肪,是一个非常有趣的生理生态过程。

小麦是世界上重要的粮食作物之一,因其具有独特的面筋,可以被加工成多种面食品,如馒头、面条、面包和蛋糕等。小麦籽粒蛋白质含量直接影响小麦的营养品质和面食品加工品质。2006年,影响小麦叶片衰老和籽粒蛋白质含量的关键基因NAM-B1被克隆,但相关的作用机制至今尚未报道。

月季(Rosa hybrida),商业上称之为“玫瑰”,是全球栽培面积最大和产值最高的观赏作物,广泛应用于切花、盆花、庭院绿化、城乡美化等。花朵是月季主要的观赏器官,花朵开放和衰老不仅对吸引昆虫授粉和繁衍后代极为重要,也是采后品质保持的重要研究方向。已经明确,花瓣衰老受到植物激素的精确调控,乙烯是加快花瓣衰老的激素,而赤霉素是延缓花瓣衰老的激素。但是,在分子层面,乙烯和赤霉素在花瓣衰老中的互作机制...
