Fig. 4.
Wild-type (WT) plants exhibit higher leaf temperatures. (A) Thermal images of WT and d1 plants under well-watered conditions. The scale on the right denotes temperatures shown in the images. (B) Leaf temperatures increase in both genotypes as relative soil water content (RSWC) declines from 30% but are always higher in the WT. (This figure is available in colour at JXB online.)
