Patent ID: 8450562

Claim:
A method for obtaining a plant with increased stress resistance comprising a. introducing a chimeric gene into a cell of a plant to obtain transgenic cells, said chimeric gene comprising the following operably linked DNA fragments: i. a plant-expressible promoter; ii. a DNA region coding for a plant-functional nicotinic acid mononucleotide adenyl transferase enzyme having at least 95% sequence identity to the amino acid sequence of SEQ ID No. 31; iii. a 3′ end region involved in transcription termination and polyadenylation; b. regenerating said transgenic cells to obtain a population of transgenic plants; and c. selecting a plant from said population of transgenic plants which exhibits increased stress resistance or selecting a plant which exhibits a reduced level of reactive oxygen species or maintains a high level of NADH under stress conditions when compared to a similar non-transgenic plant.
