A review on a role of biotechnology for cotton improvement

Abstract

Abstract

This review paper has been reviewed in 2020 on different journal articles, case study’s, notes, and short communication reports which are available at online sources all over the world. The aim of this review paper is to overview the major cotton traits improved through biotechnology and methods of gene transformations. Cotton is a multipurpose crop primarily grown for lint production which is the biggest source of natural fibers in the world. In addition, the seed is used as a raw material for edible oil and the dry meal is utilized for animal feed. So far, the biotic and abiotic stress such as fungi, viruses, bacteria, nematodes, insects, and pests is encounter problems for cotton production in the nation. Now day biotechnology has been played a great role in cotton improvement programs. The major traits were improved such as insect and disease resistance, herbicide tolerance, stacked with herbicide tolerance, and insect resistance genes and fiber traits. To do this improvement, there are different direct and indirect transformation methods such as particle bombardment, electro proration, floral dip, Agrobacterium-mediated, and T-DNA binary vector system. Among those methods, Agrobacterium-mediated transfer of DNA and particle gun bombardment were most widely used in cotton improvements.
