Research in the Monte lab is focused on how plants and algae adapt to changing light environments. Our long-term goal is to understand how photosynthetic organisms thrive under the wide dynamic range of light conditions they face in nature. We use Arabidopsis, rice and Chlamydomonas and an array of classic and advanced experimental approaches to investigate the fundamental mechanisms governing light-regulated development and growth. 

Early responses to light 

We employ seedling deetiolation to understand early development in response to light after germination in the underground darkness or in alternating night/day conditions. We have taken different approaches to identify novel regulators of deetiolation, and we are investigating how they function in the control of organ-and cell-specific growth. 

Integration of light with other cues 

Our studies on the integration of light and circadian clock signals have identified novel convergence molecular mechanisms to time daily growth. Our goal is to understand how light interacts with other internal and environmental cues to optimize growth in changing light conditions. 

Chloroplast-to-nucleus retrograde signal

Under stressful high light conditions, retrograde signals provide protection against photo-oxidative damage. We discovered that this inter-organellar communication blocks light-induced transcriptional networks to modify development and minimize exposure to deleterious radiation. Our aim is to discover the genetic mechanisms underlying the retrograde signaling induction of adaptation to high light stress.
