Autophagy is responsible for the accumulation of proteogenic dipeptides in response to heat stress in Arabidopsis thaliana

Proteogenic dipeptides are intermediates of proteolysis as well as an emerging class of small‐molecule regulators with diverse and often dipeptide‐specific functions. Herein, prompted by differential accumulation of dipeptides in a high‐density Arabidopsis thaliana time‐course stress experiment, we decided to pursue an identity of the proteolytic pathway responsible for the buildup of dipeptides under heat conditions. By querying dipeptide...
