The aim of this study was to express TaSTP13 in wheat leaf by (pst). Some abnormal behaviors of TaSTP13 are concentrated in the plasma membrane and act as a homoligomer. Seizure of TaSTP13 reduces wheat susceptibility to Pst by gene silencing (VIGS) by barley bar mosaic virus. Molecular mechanisms and regulatory genes are needed to improve tolerance to environmental stress in products. The new 4-component version (with very high expression) and the 3-component version (with low expression) contain Barley Stripe Mosaic Virus (BSMV) virus-based system which is used for the functional characteri- -zation of finger protein on the C2H2 type in wheat. The four component version, which contains a system based on the barley bar mosaic virus, has a high load capacity for the rapid and stable expression of recombinant protein in various plant species. Excessive expression of TaSTP13 increases a susce- -ptibility of Arabidopsis to powdery mildew and leads to increased glucose accumulation in the leaves.
