Abstract excerpt

Rising temperatures from global warming harm plant health, reducing crop yields and threatening food security. Understanding the impact of climate change on plant health is crucial for developing climate-resilient crops. Here, we report LIGHT-RESPONSE BRIC-A-BRACK/TRAMTRACK/BROAD (LRB) E3 ubiquitin ligases as essential components of thermosensory growth in Arabidopsis. Single lrb mutants show subtle to moderate...
