Cotton Biotechnology in Uzbekistan

WCRC WCRC2 Biotechnology

ABSTRACT
The Republic of Uzbekistan is a large producer and exporter of cotton but must overcome a number of limitations. Soil salinity has rendered about 20 % of the cotton producing area unsuitable for continued production. Increasing susceptibility to pathogens and pests reduces the yield by 10 – 12 %. Defoliants and harvest aid chemicals increase the cost of production and affect the environment adversely. Certain protein molecular markers are correlated with salt tolerance while others are receptors of abscisic acid, a key hormone in dehiscence of cotton. Key enzymes regulate the synthesis of ethylene that regulates boll opening. A fragment of DNA containing a copy of the gene for chitinase synthesis, the main enzyme in resistance to pathogens, has been cloned. New active Bt toxins have been generated from melon seeds. A vector has been constructed to provide for the transfer of foreign genes to cotton cells and a method has been developed for the transformation of single cotton cells.
