Research Areas: Abiotic stress | Circadian Rhythms | Transcriptional regulation | Systems Analysis of Transcriptional Networks

The Doherty Lab seeks to understand how plants integrate many different environmental signals when responding to an external abiotic stress such as drought.

Our goal is to improve plant yield in response to stress.

In particular, we are interested in how plants measure and track time to coordinate their activities. How do time cues affect responses to abiotic stresses such as drought and salinity?

Abiotic stresses prevent crops from attaining optimal yields and cause significant variability in food production. Understanding how plants perceive and respond to these stressors can improve yield stability.

We are interested in the intersection between the circadian clock and stress responses and are investigating how plants integrate time cues in how they respond to a stressful environment.  We focus on how the transcriptional regulatory networks of stress response change over time.

We employ biochemistry, molecular biology, network analysis, and statistical learning to identify the molecular signaling networks and changes in these networks that orchestrate adaptive stress responses in plants.
