By integrating molecular, genetic and physiological data, we hope to develop a coherent model of ABA action that could have applications in modifying seed quality or stress tolerance of plants. The Arabidopsis abscisic acid response gene ABI5 encodes a basic leucine zipper transcription factor. Abscisic acid inhibition of radicle emergence but not seedling growth is suppressed by sugars. Arabidopsis mutants with reduced response to NaCl and osmotic stress. Mutations at two new Arabidopsis ABA response loci are similar to the abi3 mutations.
Maternal effects govern variable dominance of two ABA response mutations in Arabidopsis thaliana.
