The <i>CaSBP11</i> gene functions as a negative regulator in pepper drought stress.

ABSTRACT: The SBP-box gene family, an exclusively plant transcription factor, is critical for plant growth, development, and adaptive responses to both biotic and abiotic stresses. However, its role under non-biological stresses, specifically drought, remains overlooked in pepper plants. In our previous work, we isolated an SBP-box gene, CaSBP11, from the pepper genomic database. Subsequently, we employed virus-induced gene silencing, overexpression, and protein interaction experiments to investigate the function of CaSBP11 under drought stress. Our results revealed that drought conditions significantly upregulated CaSBP11 expression, whereas ABA treatment suppressed it. Silencing CaSBP11 enhanced drought resistance in pepper, with increased stomatal aperture and ABA leve
