Mesophyll photosynthetic sensitivity to leaf water potential in Eucalyptus: a new dimension of plant adaptation to native moisture supply

What is it about?

Mesophyll photosynthetic sensitivity, a measure of how rapidly non-stomatal limitations to carbon uptake increase with declining Ψ_leaf, is greater is species from more mesic habitats. This new measurement of drought sensitivity coincides with a tradeoff of higher maximum photosynthetic rates during non-water-stressed conditions.
