BRI1-mediated removal of seed coat H3K27me3 marks is a brassinosteroid-independent process

Rishabh Pankaj, Rita B Lima, Guan-Yu Louh…·Duarte D. Figueiredo

The paper shows that BRI1-mediated removal of H3K27me3 marks is independent of brassinosteroids, while BRL3 regulates seed coat formation in a BR-dependent manner.

Osmotic-stress-inducible nuclear condensates restrict gene inducibility

Hikaru Sato, Satoru Fujimoto, Marie Sakuma…·Sachihiro Matsunaga

The paper identifies ALBA proteins that form stress-inducible nuclear condensates to suppress gene inducibility during osmotic stress in plants.

A blue light receptor CRY1 regulates de novo shoot regeneration

Min Li, Hikaru Sato, Takuya Sakamoto…·Sachihiro Matsunaga

This paper shows that CRY1 promotes shoot regeneration in Arabidopsis by suppressing ARF3-mediated salicylic acid signaling, linking blue light perception to hormonal regulation.

Combinations of maternal-specific repressive epigenetic marks in the endosperm control seed dormancy

Hikaru Sato, Juan Santos‐González, Claudia Köhler

The paper shows that combinations of repressive epigenetic marks in Arabidopsis endosperm regulate seed dormancy by modulating REF6 activity during germination.
