has an impact on flowering physiology, photomorphogenesis, shade effects, and responses to both biotic and abiotic stresses. Although recent research described the BBX gene family in numerous plants, knowledge of the BBX gene in was sparse. In this study, we identified a total of 25 genes, and phylogenetic analysis showed that these genes were divided into five subfamilies. Analyses of gene structure and motifs for each group found relative conservation. Ka/Ks values showed that most genes have undergone negative selection. qRT-PCR analyses revealed that , , , , , , , , and genes respond to salt and drought treatment. Furthermore, we cloned and genes and performed a subcellular localization experiment, which revealed that these two genes were both located in the nucleus. Transgenic yeast experiments demonstrated that and enhanced yeast tolerance to both salt and drought stresses. These findings provide a theoretical foundation for further investigation on the functions of genes in .

B-box (BBX) transcription factors are critical regulators of light-mediated anthocyanin biosynthesis, influencing peel coloration in plants. To explore their role in red mango cultivars, we identified 32 genes (-) in the mango ( L.) genome using a genome-wide analysis.

PHYTOCHROME INTERACTING FACTOR 4 (PIF4) is a vital transcription factor that controls plant growth by integrating environmental signals like light and temperature. Recent studies have shown many upstream regulators, such as HEMERA (HMR), HEAT SHOCK TRANSCRIPTION FACTORS (HSFs), TEOSINTE BRANCHED 1/CYCLOIDEA/PCF 5 (TCP5), and the B-BOX (BBX) proteins, play roles in regulating PIF4 transcription. However, the role of PIF4 in controlling its own gene expression is unknown.

B-box (BBX) proteins, a subfamily of zinc-finger transcription factors, play a crucial role in regulating various physiological and developmental processes in plants, as well as in mediating stress responses. However, comprehensive characterization of the BBX gene family in perennial ryegrass has not been performed, and their potential functions in response to abiotic stress remain unclear. In the present study, we systematically identified 26 BBX genes in the perennial ryegrass genome and classified them into five distinct groups based on their phylogenetic relationships.
