Abstract

To isolate mutants in the process of Lipid mobilization during post-germinative growth we employed a screen using the pro-herbicide 2,4-dichlorophenoxybutyric acid (2,4-DB). The phenotypes of a number of 2,4-DB-resistant mutants are compared with previously characterized mutants disrupted in beta -oxidation or the glyoxylate cycle. We conclude that the strength of 2,4-DB resistance and the ability of the seedlings to grow in the absence of exogenous sugar are inversely correlated. Sugar dependence of 2,4-DB-resistant seedlings is a consequence of impaired storage-lipid mobilization.
