冠菌素 油菜素内酯 信号调控 玉米 节间伸长 分子机制
2024/5/21
玉米是重要的粮食作物和饲用作物，提高种植密度以实现增产是满足其高需求量的有效措施。高密度种植加剧了群体内对光热、养分等资源的竞争，使玉米节间变得细长，植株发生倒伏风险增加，从而制约了玉米产量与品质的提升和机械化收获，缩短基部节间长度有助于提高玉米的抗倒伏能力。

近日，中国农业大学农学院农业农村部甘薯生物学与生物技术重点实验室刘庆昌/高少培团队在The Plant Journal上发表了题为“IbNF-YA1 is a key factor in the storage root development of sweet potato”的研究论文，揭示了IbNF-YA1-IbYUCCA4分子模块通过生长素途径调控甘薯块根形成和发育的分子机理。
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...
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。
近日，浙江农林大学园艺科学学院田莉教授团队在《Plant Biotechnology Journal》（中科院1区，IF=13.8）发表题为《CaIAA2-CaARF9模块介导了辣椒生长和免疫之间的权衡》（“CaIAA2-CaARF9 module mediates the trade-off between pepper growth and immunity”）的研究论文。该研究揭示辣椒CaI...
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...
中国科学院遗传与发育生物学研究所冯健研究组应邀在Frontiers in Plant Science撰写题为“NIN是调控结瘤共生固氮的核心因子”的综述文章（图）

氮素是植物生长发育不可或缺的重要营养元素。豆目、壳斗目、葫芦目和蔷薇目的部分植物除了能通过根系从土壤中吸收氮素外，还能与土壤中的固氮微生物（例如，根瘤菌或弗兰克氏菌）共生固氮，将空气中的氮气转化为氨，满足植物对氮素的需求。植物特异的转录因子NODULE INCEPTION (NIN)参与调控植物结瘤固氮的几乎全部过程，是共生信号通路的核心因子。
