Abstract: Abscisic acid-inducible gene expression in different plant tissues is enhanced synergistically by the co-expression of a B3-domain transcription factor and various bZIP-domain transcription factors, or a different B3-domain transcription factor. Using these transcription factors in novel formulations, as shown by examples, will confer value-added traits to transgenic plants, including, but not limited to, higher levels of heterologous gene expression, drought and salt tolerance, viability and productivity under stress, and enhanced nutrient reserves and seed properties.

Abstract: A variety of stress-related traits in plants are enhanced by the synergistic use of ABI-5 and Viviparous-1 (VP-1) like transcription factors to regulate abscisic acid (ABA)-inducible gene expression. Using these transcription factors in novel formulations, as shown by examples, will confer value-added traits to transgenic plants, including, but not limited to, drought and salt tolerance, viability under stress, and enhance nutrient reserves.
