Abstract
The automation of sequencing technologies, flooding in the knowledge of plant-pathogen interactions and advancements in bioinformatics provide tools leading to better knowledge not only of the genome of plant pathogens or microorganism beneficial to plants but also of ways of incorporating genes from microbes into plants as microbial-derived resistance. The identification of various microorganism genes playing key role during pathogensis and the dissection of the signal transduction components of the hypersensitive response and systemic acquired resistance pathways have greatly increased the diversity of options available for tailoring fungus resistant crops. The genetically engineered plants carrying these genes showed spontaneous activation of different defense mechanisms, leading the plant in an elevated state of defense. This ‘defense mode’ greatly enhances the plant’s ability to quickly react to a pathogen invasion and more successfully overcome the infection. The aim of this review is to highlight the dynamic use of genes of microorganisms in enhancing crop tolernace towards fungal intruders by examining the most relevant research in this field.

The greatest challenge for the 21st century is to provide food security to growing population of the world
The expression of Barnase is induced in rice leaves when inoculated with the spores of Magnaporthe grisea and the transgenic plant shows high levels of resistance to the rice fungal blast disease. These results suggest that transgenic plants harboring this two-component system may be exploited to acquire relatively broad spectrum and elevated resistance against fungal pathogen in various other agriculturally important crops
Recent advances in the investigation field of microorganism genome, molecular biology and transgenic technologies have enabled the plant tailors to know more about the elegant features of genes available within microorganism which require special attention
Summary
The greatest challenge for the 21st century is to provide food security to growing population of the world. Conventional plant-breeding strategies have limited scope due to the paucity of desirable genes with these traits inside the available gene pools and due to their time-consuming nature. This challenge has led agriculture sector towards gene revolution after green revolution with the help of advanced biotechnology. The gene revolution of agriculture involves the understanding and modifications in the organization of traits within the genome and conversion of traits of an organism by transferring individual genes from one species to another, i.e., the creation of a transgenic organism It has been accepted as a method of choice for directional improvement and development of disease-resistant plants. The potential and the use of genomes of microorganisms to genetically engineer new crop varieties with enhanced resistance traits are discussed, and some of the most promising research and microbial gene sources are presented
