Improvements of Fiber Yield and Fiber Fineness by Expressing the iaaM Gene in Cotton Seed Coat

摘要

Cotton,the most important natural fiber crop in the world,is a mainstay in China's economy.However,for over two decades,cotton yields both in China and U.S.have been at a plateau.One reason for this plateau is the limitation of current cotton germplasm.Cotton fibers are single cells resulting from elongated cells of the ovule epidermis.IAA regulates both plant growth and differentiation,and it has important roles in cotton fiber development.
