Abstract

Agricultural crops have developed a wide range of defensive mechanisms against stressors that are abiotic or biotic in nature. Upon pathogenic threat, plants exhibit an immense number of pathogenesis-related proteins. Innovations in the field of recombinant DNA and molecular comprehension of relationships between plants and microbes have forged the path for the detection and modelling of transcripts expressing proteins like chitinases. Chitinases have been identified in many different kinds of species, notably bacteria, fungus, insects, and plants. Tomato, potato, maize, groundnut, mustard, finger millet, cotton, lychee, banana, grape, wheat, and rice have all effectively undergone genetic modification for fungus reluctance either alone or in conjunction with various other PR proteins. In this review, we discuss the particulars of several transformation investigations aimed at developing resistance to fungi in agricultural plants.
