Abstract
The effect of enhanced cytokinin synthesis due to expression of the ipt gene from Agrobacterium tumefaciens on plant tolerance to root flooding was studied. Transgenic wheat (Triticum aestivum L.) plants carrying the ipt gene were more tolerant to flooding than wild-type plants. The effect of transformation was manifested in the higher yield and less growth inhibition during flooding. The measurements of activities of antioxidant enzymes, superoxide dismutase and catalase, as well as MDA content during flooding revealed differences between wild-type and transgenic plants that correlated with their tolerance. These results point to the protective role of cytokinins during wheat root flooding.
