Tree responses to environmental cues
Trees use environmental cues such as water availability, temperature and light to synchronize growth and development with seasonal changes, and to compete for resources with other plants. The ability of trees to effectively sense and respond to these signals requires programs to enable them to track change rapidly and adapt accordingly. This presentation will review some of our recent work on understanding tree responses to episodes of drought, elevated temperature, low temperature, and photoperiod. These cues are amongst the most important environmental factors affecting tree performance over the course of the season and in a changing climate. Examples will include recent studies on conifers using controlled environments (phytotrons) and field experiments to illustrate the significance of the interaction of multiple cues and dynamic natural environments. I will conclude with a brief overview of transcriptomic approaches used in our group to understand adaptation and plasticity in different conifers.
