ABSTRACT In the current situation, the most pressing concern facing humanity is ensuring food security for an expanding population. Unfavorable weather, limited fertile and cultivation land , and increased environmental pressures, in addition to the expanding popula tion rate, are key restraints for cultivation and foo d supply . With the progress in Plant Bio technology , it is becoming easy to control these challenges and increase crop production. It has made it possible to breed for almost any desired trait. Molecular biologists can now work on obtaining desired trait and knocking out the undesired tra i t gene , thanks to advances in Plant Biotechnology . OUTLINE This article will emphasis on the plant biotechnology tools used for crop improvements. INTRODUCTION Agricultu ral Biotechnology refers to the techniques used to introduce specific desirable traits into plants, animals and microorganisms. By the virtues o...
