The Russian wheat aphid (RWA) is a pest of cereals, such as wheat and barley. It feeds on these hosts by injecting saliva into the plants’ phloem tissue and consuming the mixture of saliva and photoassimilates. It has been ...

The battle of wheat against pests and pathogens can be strengthened by genetically engineering the wheat plant for disease tolerance, e.g. by enhancing the expression of chitinase and â-1,3-glucanase genes. In order to ...

Wheat is one of the major food crops consumed by man and is grown in a wide range of environments. One constraint in the production of wheat is the different diseases attack the crop. One such a diseases is leaf rust. Leaf ...

This thesis investigates the effect of Russian wheat aphid (RWA; Diuraphis noxia) infestation on the defence responses of the bread wheat line, PI 137739, on a molecular level. PI 137739 is known to contain the RWA resistance ...

One of the most important photosynthetic enzymes in a plant is ribulose-1,5¬bisphosphate carboxylase/oxygenase (Rubisco), which plays a key role in carbon fixation. Degradation of this enzyme leads to decreased carbon ...
