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...
Biosynthesis and regulation of salicylic acid and N-hydroxypipecolic acid in plant immunity
plant immunity Salicylic acid (SA) Biosynthesis
2024/2/4
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...
Redundant CAMTA transcription factors negatively regulate the biosynthesis of salicylic acid and N-hydroxypipecolic acid by modulating the expression of SARD1 and CBP60g
CAMTA Salicylic acid (SA) N-hydroxypipecolic acid (NHP) SARD1 CBP60g immune signaling
2024/2/5
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...
A role for tocopherol biosynthesis in Arabidopsis thaliana basal immunity to bacterial infection
tocopherols tocopherol biosynthesis VTE2 Arabidopsis
2024/2/28
Tocopherols are lipid-soluble antioxidants synthesized in plastids of higher plants and other photosynthetic organisms. The four known tocopherols alpha-, beta-, gamma- and delta-tocopherol differ in ...
The F-box Protein SAGL1 and ECERIFERUM3 Regulate Cuticular Wax Biosynthesis in Response to Changes in Humidity in Arabidopsis
SAGL1-CER3 Wax biosynthesis negatively regulating
2024/2/29
Cuticular waxes that cover the above-ground parts of land plants are essential for their survival in terrestrial environment. However, little is known about the regulatory mechanisms underlying cuticu...
Occurrence and biosynthesis of cytokinins in poplar
Cytokinin Expression Isopentenyltransferase Poplar Topolin tRNA
2024/3/5
Isoprenoid and aromatic cytokinins occur in poplar as free compounds and constituents of tRNA, poplar isopentenyltransferases are involved in the production of isoprenoid cytokinins, while biosynthesi...
