Transgenic Wheat with Increased Polyamine Content
January 25, 2008| |
A group of researchers from the Universitat de Lleida in Spain have developed transgenic wheat lines with increased polyamine contents. By transferring an oat gene coding for the enzyme ADC, the scientists obtained wheat plants expressing elevated levels of spermidine spermine and other polyamines. Polyamines have been shown to protect plants from drought stress. The increased levels of polyamines were also maintained in progeny plants and seeds. In a previous study, expression of ADC gene in rice resulted to lines with drought resistant characteristics. The transgenic wheat lines developed will the basis of further in depth investigations to elucidate the role of polyamines in drought stress response in cereals.
