Tissue-specific expression of a defence-related peroxidase in transgenic wheat potentiates cell death in pathogen-attacked leaf epidermis.

ABSTRACT: Gene technology can offer creative solutions to problems of agronomical relevance, which may not be solved by conventional breeding methods. One of the major problems of wheat cultivation is disease caused by a number of fungal pathogens including the wheat powdery mildew fungus Blumeria graminis f.sp. tritici (Bgt). Transgenic wheat plants that constitutively express the coding sequence of the defence-related wheat peroxidase TaPrx103 (previously TaPERO) in shoot epidermis under the control of the wheat GstA1 promoter were generated and found to exhibit enhanced resistance to Bgt (Altpeter et al., Plant. Mol. Biol. 57, 271-283). Here, I report on physiological and molecular analyses of these plants in order to assess the mode of action of the peroxidase encoded by the TaGstA1:TaPrx103 tra
