Calum is interested in how plant responses to environmental stress can be governed by the circadian clock, and the signalling pathways associated with these processes.
The circadian clock allows plants to anticipate daily changes in environmental conditions. Effective communication of timing information from the nuclear clock to the rest of the plant cell is essential to allow plants to prepare for predictable daily stresses.
In his work, Calum is investigating how changes in the circadian regulation of chloroplast gene expression can influence plant responses to environmental stress.
A greater understanding of the signalling systems responsible for integrating timing information and stress responses will be key in the development of crop varieties with heightened stress tolerance.
Calum has begun working with wheat to test whether recent discoveries in Arabidopsis thaliana are translatable to polyploid crop species.
