A grey coloured Arabidopsis leaf epidermis, with black cell walls. Each cells has a colourful blobs - a nuclear localised fluorescent ABA sensor, with warm colours indicating high concentrations, and cooler colours indicating lower concentrations.

The Rowe lab is recruiting a #PlantScience PhD student for 2025! You'll use our new ABACUS FRET biosensors to map the leaf #AbscisicAcid accumulations at low humidity in Arabidopsis, wheat and rice to understand how ABA regulates stomatal dynamics. #PhDposition

Moisture-responsive root-branching pathways identified in diverse maize breeding germplasm Plants grow complex root systems to extract unevenly distributed resources from soils. Spatial differences in soil moisture are perceived by root tips, leading to the patterning of new root branches t...

Proud to share our latest published work on moisture responsive root development-a process we call hydropatterning! We find that this process has been under differential selection during maize breeding and the gaseous hormone ethylene prevents branching in air.

Engineering source-sink relations by prime editing confers heat-stress resilience in tomato and rice Lou et al. engineered source-sink relations to improve carbon partitioning by targeted insertion of heat-shock cis-elements into cell-wall-invertase genes using prime editing. This delivers climate-smart crops with higher yields under normal conditions and stable yields under heat stress in tomato and rice.
