Abstract:
1. A method of producing a high-fiber-yield cotton plant, comprising the steps of: (a) inserting into a cell of a cotton plant a transgene to give a modified cotton cell, wherein, the transgene comprises a sequence under the control of an inducible promoter, and the sequence encodes a protein, wherein the expression of the protein reduces the activity of one or more enzymes that function in oil production in cottonseed; and (b) regenerating a whole cotton plant from the modified cotton plant cell to give a modified cotton plant; (c) selecting the high-fiber-yield cotton plant containing the transgene from one or more modified cotton plants; (d) applying an inducing agent to activate the inducible promoter in the high-fiber-yield cotton plant; wherein the sequence is a mutant delta-12 fatty acid desaturase (FAD2) gene from canola; and wherein the high-fiber-yield cotton plant has increased fiber yield relative to a control cotton plant, when the transgene in the high-fiber-yield cotton plant is expressed due to the activation by the inducible promoter.
