Functional divergence of the repressors of photomorphogenesis SPA2 and SPA3 during Arabidopsis seedling deetiolation

Zhen Cao, Vivian Feldmann, Ira Trivedi, Ute Hoecker

This study investigates the functional divergence between SPA2 and SPA3 repressors during Arabidopsis seedling deetiolation, revealing that SPA2's instability under light counterbalances its strong repressor activity.

Arabidopsis GLK transcription factors interact with ABI4 to modulate cotyledon greening in light-exposed etiolated seedlings

Pengxin Yu, Friederike Saga, Miriam Bäumers, Ute Hoecker

This paper shows ABI4 inhibits GLK1 and GLK2 to limit Pchlide biosynthesis in dark-grown Arabidopsis seedlings, preventing phototoxicity upon light exposure.
