Gilroy Lab Research Focus
We are interested in how plants sense and respond to their environment and how these signals regulate plant development. The research emphasis of the lab is to try and understand these processes at the cellular level. We combine advanced microscopy approaches such as confocal microscopy with biochemistry and molecular biology to address a wide range of biological questions:
- How do plants sense and respond to abiotic stresses?
- How do roots and shoots sense and respond to gravity and touch stimuli?
- How do plants regulate growth?
- How do plants respond to the spaceflight environment?

Plants are an essential part of a bioregenerative life support system
Right Video: Astronauts Scott Kelly, Kjell Lindgren, and Kimiya Yui all munched on red romaine lettuce this afternoon, except unlike your sad desk salad, this produce was grown on the International Space Station. It was the first time people have eaten food cultivated in space. Aug 10, 2015 the birth of the first ever Space-Farmers. Video Curtesy of UW-Madison.

Do plants feel pain?
Right Video: Epifluorescence time-lapse photography showing Arabidopsis plants responding to a wound by sending a long distance "Calcium wave" across the plant. This signal activating the Jasmonic acid signaling system and inducing systemic defense networks.
What is the most stressful factor that life encounters living in low earth orbit on the ISS?

MANGO: ISS microbiome
Right Video: A video showing the prevalence of microbes in a built environment.
Project MANGO is a collaboration coordinated by the UW Gilroy AstroBiology team with both the NASA Jet Propulsion Laboratory's (JPL) "Interplanetary protection team", the European Bioinformatics Institute (EBI) and the NASA Ames GeneLab team. This collaboration has lead to the incorporation off the ISS microbiome into the MGNfy database making it comparable to the earth and oceans microbiome projects.
