There is a very immediate and very current requirement for increasing the security of food on global level for reversing back the uplifting trends of cancer rates, protecting the environmental health and other climatic changes. The review focuses on the fungi that helps for providing remedies to such problems. We discussed the major aspect of stress biology of fungus on the special and current affairs of genetics involved. The area of biology has a very close significance in pure and advanced researched on fungal stress systems, biological control of insect pests, role of saprotrophic fungi in field of forestry and agriculture. Stress is an unfavored condition for an organism which includes fungus too. For overcoming the stress organisms shows the heat shock proteins also called chaperons for performing its basic biological purpose. Thus, it became very important for understanding the basic purpose of heat shock proteins which express themselves in response to the stress conditions of fungi. Osmotic stress, pH , temperature changes caused by stresses of these heat shock proteins is also briefly discussed.
