TRICHODERMA GST GENE CONSTRUCT 
TO ENHANCE TOLERANCE TO ABIOTIC STRESS

Widespread use of chemical fertilizers, pesticides and heavy irrigation has resulted in problems like heavy metal and xenobiotics contamination of soil as well as increased soil salinity, all leading to yield loss. Crop plants are not naturally equipped with a machinery to cope with elevated levels of toxicity imposed by the intensive agriculture, as well as stresses imposed by climate change. Genes for tolerance to heavy metals and abiotic stresses could be introduced in the plants from other species. A GST gene from Trichoderma virens was expressed in the experimental plant- tobacco. The transgenic plants exhibited tolerance to a variety of abiotic stresses like salinity, heavy metal cadmium and the toxic xenobuitic anthracene (a ployaromatic hydrocarbon highly toxic to plants). This plasmid construct, can be expressed in a variety of crop plants to enhance tolerance to abiotic stresses.

Trichoderma Gst Gene Construct  For Plant Transformation

Note: Figure shows plants not treated (NT) and treated (T) with the GST gene construct and exposed to abiotic stress.
