Multifaceted roles of BBX transcription factors: impacts on key agronomical traits and environmental resilience

open access: yesNew Phytologist, Volume 250, Issue 2, Page 762-787, April 2026.
Summary B‐box (BBX) proteins were initially characterized as transcription factors connecting light signaling to the regulation of flowering time and seedling photomorphogenesis. However, over the last decade, increasing evidence has shown that they integrate light and hormone signaling, modulating multiple physiological processes during plant life. In
