Abstract:
Sugarcane a main agro-industrial crop, not only a prime potential source of bio-energy but also satisfies 70% of world’s sugar needs. Our whole sugar need and sugar industry is exclusively dependent on the fate of this crop. Crop yield have been drastically decreasing due to constant attack by the fungal pathogens and insect pests. In response to the attack, different defense mechanisms are activated by the plants including expression of pathogenesis-related proteins i.e. glucanase, chitinase, chitosanase, thaumatin, peroxidase, metallothionine and endoproteinase. Some more proteins involved in defense system are: WRKY, glycoproteins, NBS-LRR and catalases. Most of the PR proteins are involved in plant defense response. WRKY are transcription factors in PR proteins, glycoproteins and NBS-LRR recognize insects/pests and disrupts physiological activity of the pathogens. While catalases detoxify reactive oxygen species. New developments in molecular biology provide a rapid solution to overcome these stresses. Numerous endogenous plant genes have been explored to play potential role in biotic stress tolerance despite the complex genome of sugarcane. Recently, the transgenic overexpression of the PR proteins in crop plants has been found useful in improving resistance against plant diseases. Some of them have proved to be real success while others are at development level.
