OsGSK2‐OsTCP19 Module Integrates Nitrogen and Brassinosteroid Signaling to Regulate Nitrogen Utilization and Root Growth in Rice OsGSK2-OsTCP19 module regulating nitrate response and lateral root (LR) development. Low-nitrate condition results in reduced BR response, accumulation of OsGSK2 and phosphorylated OsTCP19, which sup...

Great work by Chaudhary et al. (2025) on how #FERONIA (FER), a cell wall integrity sensor, is essential for limiting #PlantCellWall damage and preventing cell rupture during #brassinosteroid (BR)-induced cell elongation in #Arabidopsis.
BR signaling promotes FER accumulation at the plasma membrane.

Flow diagrams and micrographs illustrate that low-to-moderate brassinosteroid concentrations promote stomatal formation in Arabidopsis hypocotyls via upregulation of SPEECHLESS, and independently of BRASSINOSTEROID INSENSITIVE2 (BIN2). High brassinosteroid concentrations or direct BIN2 inhibition suppress stomatal development. BIN2 promotes stomatal formation by inactivating BRASSINAZOLE-RESISTANT1, revealing distinct regulatory pathways between hypocotyls and cotyledons.

Park et al. reveal that #brassinosteroid signaling has a dual regulatory role in controlling stomata development in #Arabidopsis hypocotyls🌱

Imaging and gels illustrate that overexpression of the BR biosynthesis gene DWARF (DWF) or the key BR signaling gene BRASSINAZOLE-RESISTANT1 (BZR1) increases ABA levels in response to chilling stress via positively regulating the expression of the ABA biosynthesis gene 9-CIS-EPOXYCAROTENOID DIOXYGENASE1 (NCED1). BR-induced chilling tolerance was mostly dependent on ABA.
