25 Years of thermomorphogenesis research: milestones and perspectives

Trends Plant Sci. 2023 Oct;28(10):1098-1100. doi: 10.1016/j.tplants.2023.07.001. Epub 2023 Aug 11.


In 1998, Bill Gray and colleagues showed that warm temperatures trigger arabidopsis hypocotyl elongation in an auxin-dependent manner. This laid the foundation for a vibrant research discipline. With several active members of the 'thermomorphogenesis' community, we here reflect on 25 years of elevated ambient temperature research and look to the future.

Keywords: high temperature signalling; hypocotyl; phytohormones; thermomorphogenesis; thermosensor.
