Brassinosteroid-Activated BRI1-EMS-SUPPRESSOR 1 Inhibits Flavonoid Biosynthesis and Coordinates Growth and UV-B Stress Responses in Plants
UV-B light BES1 brassinosteroids flavonoids
2023/12/21
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...
采用分解袋法对自然和UV-B辐射滤减环境下的杉木凋落叶进行分解试验. 结果表明： 与对照相比,UV-B辐射滤减处理使杉木凋落叶的分解速率降低了69.6%(P＜0.001), 凋落叶中氮、磷和木质素的相对含量分别增加150%、83.3%和13.8%, 抑制了钾和碳的释放. 木质素光降解在杉木凋落叶分解过程中的作用不明显. UV-B辐射可以加快杉木凋落叶的分解，促进氮、磷、钾和碳的释放，以及杉木林凋落...
