Description
Yaping Yue, Biao Liu, and five co-authors published a 2025 plant study on how rice survives heat. Two control systems in the cell, one for metabolism and one for the chemical tags on DNA packaging, must cooperate under stress. How they talk to each other was unclear.
The team focused on an enzyme called PK1, better known for a step in sugar breakdown. Extra PK1 made rice plants tolerate heat better, while losing it cut recovery after heat stress. Heat itself switched PK1 on and sent it into the nucleus. There it tagged histones and boosted a second regulator, GCN5, which in turn boosted PK1 back. This two way loop ties fuel use to gene switching in heat defense.
