PAP accumulates under drought conditions in Arabidopsis. Correlation between relative water content (RWC) of plants and PAP concentration on a dry weight (DW) basis ± SD (n > 8) during drought. Days in drought is shown in italics. alx8 carries a loss-of-function SAL1 mutation. (Reprinted from Figure 3A of Estavillo et al. [2011].)
