Elevated temperatures resulting from climate change adversely affect natural and crop ecosystems, necessitating the development of heat-tolerant crops. We established a framework to precisely identify wheat protein-phosphorylated sites associated with varying temperature sensitivities. We identified specific kinases primarily associated with a specific temperature, but our results also suggest a striking overlap between cold and heat signaling. We furthermore demonstrated that the phosphorylation state of a specific set of proteins creates a unique signature for heat stress tolerance. These findings can potentially aid in the identification of targets for breeding or genome editing to enhance sub/supra optimal temperature tolerance.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
