Presentation description

Plant growth integrates environmental cues with development. In thermomorphogenesis, high temperature triggers hypocotyl elongation via auxin pathways. We identify NCP as a regulator of this process: NCP mutants show reduced elongation, impaired auxin gene expression, and fail to accumulate PIF7 protein despite normal PIF4/PIF7 transcripts. Our results suggest NCP stabilizes PIF7 to encourage auxin-dependent thermal growth responses.
