CLE19 suppresses brassinosteroid signaling output via the BSL-BIN2 module to maintain BES1 activity and pollen exine patterning in Arabidopsis
{{output}}
The pollen exine serves as a protective barrier and signaling interface essential for male fertility in flowering plants. Its precise patterning depends on coordinated interactions between microspores and tapetal cells. While the CLAVATA3/EMBRYO SURROUNDING RE... ...
