MYB30 Promotes PIF4 and PIF5 Accumulation in the Light

Yan et al. discovered that MYB30, an R2R3-MYB family transcription factor, is a negative regulator of Arabidopsis photomorphogenic development and promotes PIF4 and PIF5 accumulation under prolonged red light irradiation.

PIF8: a new player in far-red light signaling

Oh et al. identify a far-red light-specific role for PIF8. Plant Cell https://doi.org/10.1105/tpc.19.00515 By Jeonghwa Oh, KAIST Background: When plants are in the dark, their stems get longer to search for light. When reaching the light, plant photoreceptors called phytochromes perceive light…

A new B-BOX containing protein regulates red light photomorphogenesis ($) (PNAS)

As the primary red light photoreceptor in Arabidopsis, phyB affects various developmental processes, such as seed germination, shade avoidance, etc. PIF3 is a key repressor of phyB-mediated photomorphogenesis that is degraded in red light. Recently Heng et al. identified a positive regulator of red light…
