Warm temperature and mild water stress cooperatively promote root elongation

Hayes and Leong et al. show that warm temperature and mild water stress synergistically enhance root elongation in Arabidopsis. The response is mediated by SnRK2.2/2.3 and COP1 through regulation of H...

How do potato cultivars cope with salt stress? With Rumyana Karlova (PPH-WUR) we are glad to share that our paper investigating potato plants' response to salt stress is out www.sciencedirect.com/science/arti... ! with @pph-wur.bsky.social @christatesterink.bsky.social

Potato cultivars use distinct mechanisms for salt stress acclimation

Soil salinity induces osmotic stress and ion toxicity in plants, detrimentally affecting their growth. Potato (Solanum tuberosum) suffers yield reduct…

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.

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...
