Plants respond to warm temperature by increased elongation growth of organs enhance cooling capacity. Phytohormones, such as auxin and brassinosteroids, regulate this process. However, our view on the players involved in temperature-mediated remains fragmentary. Here, we show that leads an expression JOXs ST2A, genes controlling jasmonate catabolism. This elevated 12HSO4-JA level consequently a reduced bioactive jasmonates. Ultimately results more JAZ proteins, which facilitates plant under conditions. Taken together, understanding conserved role signalling during thermomorphogenesis contributes ensuring food security changing climate.
