Gene Details:

• Gene ID: Zm00001eb361520
• Gene Symbol: ZmBRI1a
• Gene Name: BRASSINOSTEROID INSENSITIVE 1A
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The high expression levels of ZmBRI1a and zmbri1b, but not the other brl genes, suggest that the BRI1 receptors encoded by these two genes are of primary importance for regulating leaf growth.
• ZmBRI1a and Zmbri1b expression was high at the base of the leaf in the zones of active cell division and cell elongation, gradually declining as cells differentiate and mature.
• ZmBRI1a encodes a brassinosteroid receptor.
• Autophagy receptor ZmNBR1 promotes the autophagic degradation of ZmBRI1a and enhances drought tolerance in maize.
• Determined that BRASSINOSTEROID INSENSITIVE 1A (ZmBRI1a), a brassinosteroid receptor of the BRI1-like family, interacts with ZmNBR1.
• ZmNBR1 regulates the expression of autophagy-related genes, thereby increasing autophagic activity and promoting the autophagic degradation of ZmBRI1a under drought stress, thus enhancing drought tolerance in maize.
