2024年1月24日,万建民院士领衔的南京农业大学和中国农业科学院作物科学研究所的科研团队合作在国际著名期刊The plant cell在线发表了题为“Rice LIKE EARLY STARVATION1 cooperates with FLOURY ENDOSPERM6 to modulate starch biosynthesis and endosperm development ”的研究...
Ultraviolet B (UV-B) light is a potential stress factor in plants, but how plants coordinate growth and UV-B stress responses is not well understood. Here we report that brassinosteroid (BR) signaling...
干旱是限制植物种植分布、生长发育以及作物产量的主要非生物胁迫因素之一。棉花是重要的经济作物,新疆是中国棉花种植的主要地区,占全国棉花种植面积80%以上。干旱胁迫是影响新疆棉花生产重要的非生物胁迫因素。挖掘关键抗旱基因,揭示棉花对干旱胁迫的应答机制,培育耐逆新材料和新品种,不仅具有重要的科学研究价值,也是服务棉花可持续发展的重要保障。NAC转录因子在植物非生物胁迫信号中起着重要的转录调控作用。然而,...
次生代谢产物异黄酮是一类主要在豆科植物中合成的多酚类物质。异黄酮不仅利于豆科植物应答生物和非生物胁迫、诱导根瘤形成等,而且对人体具有重要的保健和药用价值,比如预防和治疗癌症、心脑血管疾病和骨质疏松等。大豆是工业化生产异黄酮的重要来源,主要含有12种异黄酮物质及其衍生物。根据其化学结构的差异,可将其分为游离型苷元(aglycone)和结合型糖苷(glycoside)两大类,其中结合型糖苷占异黄酮总量...
2023年7月28日,The Plant Journal在线发表了南京农业大学作物遗传与种质创新利用全国重点实验室油菜遗传育种团队的最新研究成果“Mutation to a cytochrome P450-like gene alters the leaf color by affecting the heme and chlorophyll biosynthesis pathways in Br...
Caffeine is a characteristic bioactive compound in tea and coffee plants, which is synthesized and accumulated extensively in leaves and seeds. However, little is known about the regulatory mechanism ...
Theanine is a unique major amino acid in tea plants responsible for umami taste and mental health benefits of tea. However, theanine biosynthesis and physiological role in tea plants are not fully und...
Theanine, one of the most important components of teas, confers the umami taste and relaxation effect of tea infusion. As a non-proteinogenic amino acid, theanine solely accumulates to high levels in ...
Theanine and flavonoids (especially proanthocyanidins) are the most important and abundant secondary metabolites synthesized in the roots of tea plants. Nitrogen promotes theanine and represses flavon...
缩节胺(MC)作为一种赤霉素生物合成抑制剂,可以增加棉花对钾离子的吸收,从而对棉花生长产生积极调节作用,但是潜在生理机制尚不清楚。本研究利用非损伤微测技术测定表明,除了增加根生物量之外,MC浸种还可以通过增加钾离子流入和/或减少幼苗根尖的钾离子外排来增加钾离子吸收。此外,该研究发现,MC处理可以引起质膜超极化,可以通过增强H +-ATPase的基因表达(HA2/5/11)、蛋白积累(GhAHAs总...
Shading was thought as an effective approach to increase theanine in harvested tea shoots. Previous studies offered conflicting findings, perhaps since the integration of theanine metabolism and trans...
The growth of leaves and biosynthesis of characteristic secondary metabolites are critically important for tea production and quality control. However, little is known about the coordinated regulation...
Auxin is a phytohormone essential for plant development. However, our understanding of auxin-regulated endosperm development remains limited. Here, we described rice YUCCA (YUC) flavin-containing mono...
Salicylic acid (SA) has long been known to be essential for basal defense and systemic acquired resistance (SAR). N-hydroxypipecolic acid (NHP), a recently discovered plant metabolite, also plays a ke...
Two signal molecules, salicylic acid (SA) and N-hydroxypipecolic acid (NHP), play critical roles in plant immunity. The biosynthetic genes of both compounds are positively regulated by master immune-r...
