Proteomic analysis of Arabidopsis plants subjected to drought,
heat stress, or a combination of drought and heat stress. A, leaf
water potential in wild-type (Col-0) Arabidopsis plants subjected to
drought stress. B, leaf water potential, relative to control, for
well watered, or drought-stressed plants before and after 6 h at 42 °C.
*, indicates statistical significance (p < 0.05).
C, Venn diagrams of protein spots that increased (Up) or
decreased (Down) in their intensity in response to drought, heat
stress, or a combination of drought and heat stress.
