1. A method of producing a stress tolerant cotton plant comprising the steps ofa) introducing a chimeric gene into a cotton cell, to generate a transgenic cotton cell, said chimeric gene comprising the following operably linked DNA fragments:

  • i) a plant expressible promoter;

    ii) a transcribable DNA region comprising(1) a first DNA region comprising a nucleotide sequence of at least 19 out of 20 consecutive nucleotides selected from the nucleotide sequence of a parp2 gene, parp2 cDNA from a cotton species, or from a species related to a cotton progenitor species;

    (2) a second DNA region comprising a nucleotide sequence of at least 19 out of 20 consecutive nucleotides from said first DNA region;

    whereby said first DNA region and said second DNA region are in an inverted repeat orientation with each other and wherein an RNA molecule transcribed from said transcribable region is capable of forming a double stranded RNA region between an RNA region transcribed from said first DNA region and an RNA region transcribed from said second DNA region; and

    iii) a DNA region comprising a transcription termination and polyadenylation signal functional in plants;

    b) regenerating said transgenic cotton cell to obtain a transgenic cotton plant; and

    c) identifying a transgenic cotton plant which is more resistant to abiotic stress conditions than an untransformed cotton plant.
