Perception of volatile organic compounds (#VOCs) from wounded #arabidopsis plants identifies two green leaf volatiles (#GLVs), (Z)-3-hexenal and (E)-2-hexenal. Perception starts in #guard cells and subsequently in #mesophyll cells, triggering the expression of biotic and abiotic stress-responsive genes in a calcium-dependent manner.

In our new paper we question the conventional understanding that #diffusional limitations of CO2 contribute to the reduction in #photosynthesis at high #temperatures. We suggest that #stomata and #mesophyll membranes could work strategically to facilitate #transpiration cooling and #CO2 supply, thus alleviating #heat #stress on leaf photosynthetic function, albeit at the cost of reduced #WateUseEfficiency.
