Translational regulation plasticity shapes wheat grain adaptation to heat stress.

ABSTRACT:

Background

Extremely high temperatures due to global warming are increasingly threatening crop production, and plants have evolved highly sophisticated mechanisms to respond to harsh environmental stresses and survive. At the translational level, how bread wheat responds to high temperatures remains largely unknown.

Results

We use ribosome profiling and high-throughput sequencing to investigate the translatome of wheat grains in response to high temperatures. Our study reveals that heat stress profoundly reshapes the translatomic landscapes, significantly affecting the translation of the mRNAs involved in the translation process, grain development, and heat stress response. A subset of the upstream open reading frames (uORFs) and RNA-binding proteins specifically link to the
