"Plant breeders are always interested in new genetic resources. In the past, the sources have been limited to existing\r\ngermplasm. Genetic engineering now provides the opportunity for almost unlimited strategies to create novel\r\nresources. As a first stage, the Applied Biotechnology Center (ABC) at CIMMYT developed a method for the mass\r\nproduction of fertile transgenic wheat (Triticum aestivum L.) that yields plants ready for transfer to soil in 13–14\r\nweeks after the initiation of cultures, and, over the course of a year, an average production of 5–6 transgenic plants\r\nper day. CIMMYT elite cultivars are co-bombarded with marker gene and a gene of interest with co-transformation\r\nefficiencies around 25–30%. The reliability of this method opens the possibility for the routine introduction of\r\nnovel genes that may induce resistance to diseases and abiotic stresses, allow the modification of dough quality,\r\nand increase the levels of micronutrients such as iron, zinc, and vitamins. The first group of genes being evaluated\r\nby the ABC are the pathogenesis related (PR) proteins, such as the thaumatin-like protein (TLP) from barley,\r\nchitinase, and 1–3 β-glucanase. Stable integration of the genes in the genome and inheritance in the progeny were\r\ndetermined by phenotypical analyses that challenged the plants against a wide range of pathogens. Using these\r\ngenes, we have recovered more than 1200 independent events (confirmed by PCR and Southern blot analyses)\r\nthat show responses to the pathogens that range from tolerance to hypersensitive reactions. The quantity and antifungal\r\nactivity of the endogenous thaumatin-like proteins were analyzed in T 1 and T2 progeny plants.Western blot\r\nanalyses showed different protein patterns of the wheat endogenous TLPs. Preliminary results indicated that some\r\npatterns increased the resistance of transgenic wheat plants to Alternaria triticina. This relationship is being further\r\ninvestigated."^^ . "2001" . .
