Overview of the molecular mechanism of adaptation to heat stress in the shoot apical meristem (c) the authors.

The research published in Plant Communications reveals the pivotal role of the transcription factor HSFA7b in regulating heat stress memory at the shoot apical meristem (SAM) in Arabidopsis.

t shows that HSFA7b directly controls the expression of ethylene biosynthesis and key signaling genes, controlling controlling the ethylene response and ensuring that ethylene homeostasis is maintained at the SAM during heat stress the ethylene response at the SAM during heat stress.

These findings provide valuable insights into the molecular mechanisms underlying plant responses to heat stress following an initial priming event and have profound implications for improving crop resilience to fluctuating temperatures.
