Abstract

This project seeks to understand how plants perceive and respond to small changes in ambient temperature (in the range 12 ºC to 27 ºC). Ambient temperature is one of the most important environmental factors controlling plant development, and climate change has already perturbed the phenology and distribution of wild-plants. Understanding how plants perceive temperature is a key stepping-stone towards breeding plants tolerant of temperature stress. The first phase involved determination of the ambient temperature transcriptome, that is the complete set of genes that undergo a significant expression change within hours of shifting between 22 C and 16 C. Using created transgenic lines containing reporters for positive (LUCIFERASE) as well as negative (tms2) selection in forward genetic screens, we have isolated mutants in Arabidopsis thaliana that are impaired in their ability to sense or respond to temperature appropriately. We are cloning the genes involved and determining the molecular basis of temperature perception. In a complementary approach, we are studying temperature perception in the model grass system Brachypodium distachyon.
