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。

大豆是世界上最重要的油料作物之一,也是豆制食品加工业的重要原料。解析大豆产量和品质调控的遗传机制和关键基因,对于通过分子设计育种培育高产优质大豆新品种具有重要意义。大豆产量和品质相关农艺性状大部分是复杂性状,受一因多效和遗传连锁的影响,性状间呈现耦合性相关。挖掘协同调控产量和品质相关性状的关键基因和解析重要农艺性状耦合的遗传网络,可以为培育高产优质大豆品种提供重要理论基础。以往的研究往往针对大豆单...
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...
Kalancho? PPC1 is Essential for Crassulacean Acid Metabolism and the Regulation of Core Circadian Clock and Guard Cell Signaling Genes
