Abstract
Abstract Two wilty tomato mutants, flacca and sitiens , fail to increase their endogenous ABA concentration in response to water stress. Instead, a compound accumulates which has been identified as 2‐ trans ‐ABA alcohol. Levels of this compound have been estimated for three wilty mutants and the control; both before and after water stress. When the compound was biosynthesized in the presence of 18 O 2 , one atom appeared to be incorporated into the primary alcohol group. The possible implications of this for the ABA biosynthetic pathway are discussed.
