Dynamic control of plant water use using designed ABA receptor agonists (Science)

ABA is synthesized in response to water stress and promotes stomatal closure, thus decreasing transpiration. Crop yields can be increased by controlling transpiration early in the growing season, ensuring that soil water resources persist through the seed-set period. Building upon earlier studies, Vaidya,…

ALIX helps to open the pore

García-León et al. reveal a function for a trafficking protein in stomatal aperture regulation. Plant Cell https://doi.org/10.1105/tpc.19.00399 By Marta García-León and Vicente Rubio Centro Nacional de Biotecnología (CNB-CSIC) Darwin, 3. 28049 Madrid, Spain  Background: Plants protect…

The xerobranching response represses lateral root formation when roots are not in contact with water (Curr. Biol. - $)

Roots navigate through the soil, foraging for water and nutrients. Orman-Ligeza et al. observed that lateral root development is repressed when the roots are growing through the soil air spaces. Exposure to water deficit induced transcriptome reprogramming in barley roots of genes involved in many hormone…

A gene‐stacking approach to overcome the trade‐off between drought stress tolerance and growth in Arabidopsis (Plant J)

In the face of increasing incidence of drought events, developing drought-tolerant plants becomes urgent matter. However, the increase in drought tolerance often coincides with the significant reduction of plant size, as in the case of overexpressing DEHYDRATION-RESPONSIVE ELEMENT-BINDING PROTEIN 1A…

FERONIA receptor kinase contributes to plant immunity by suppressing jasmonic acid signaling in Arabidopsis thaliana (Curr. Biol. - $)

Receptor-like kinase FERONIA plays important role in the regulation of plant growth as well as interactions with the environment. In order to understand how FER affects plant growth Guo et al. examined global transcriptome changes in fer mutant. The authors observed that genes up-regulated by stress…
