摘要:
A transgenic plant engineered to have increased desiccation tolerance, increased drought tolerance or increased water use efficiency, the plant transformed with an artificial DNA construct comprising a transcribable nucleic acid molecule encoding a polypeptide requiring both ABA and ABI3 to influence desiccation tolerance. Also provided are DNA constructs and methods of producing a transgenic plant engineered to have increased desiccation tolerance, increased drought tolerance or increased water use efficiency.

摘要:
The preparation and use of nucleic acid promoter fragments homologous to the Em gene of wheat to bring the expression of selected genes in plants under external control are described. The Em promoter fragment is responsive to abscisic acid (ABA) and other compounds possessing ABA-like activity. Through transformation of protoplasts and plant cells with recombinant DNA constructs incorporating such promoter fragments, operably linked selected genes are expressed in response to ABA and compounds possessing ABA-like activity. The application of such promoter fragments and constructs to transient assay systems to predict the likelihood of stable transformation in plants is disclosed.
