Summary:B-box containing proteins (BBXs) are a class of zinc-ligating transcription factors or regulators that play essential roles in various physiological and developmental processes in plants. They not only directly associate with target genes to regulate their transcription, but also interact with other transcription factors to mediate target genes' expression, thus forming a complex transcriptional network ensuring plants’ adaptation to dynamically changing light environments. This review summarizes and highlights the molecular and biochemical properties of BBXs, as well as recent advances with a focus on their critical regulatory functions in photomorphogenesis (de-etiolation), shade avoidance, photoperiodic-mediated flowering, and secondary metabolite biosynthesis and accumulation in plants.
