The role of ABI1 in abscisic acid signal transduction: from gene to cell.

Symposia of the Society for Experimental Biology - 1 Jan 1998

Leung J, Merlot S, Gosti F, Bertauche N, Blatt M R, Giraudat J

Abstract excerpt

The semi-dominant abi1-1 mutation of Arabidopsis interferes with multiple aspects of abscisic acid signal transduction resulting in reduced seed dormancy and sensitivity of root growth in ABA. Furthermore, the mutant transpires excessively as a result of abnormal stomatal regulation leading to a wilty phenotype. The ABI1 gene has been cloned. The carboxyl-terminal domain of the predicted ABI1 protein is related...
