Abstract:
A method for increasing the rate of boll production and the number of bolls produced by a transgenic Gossypium hirsutum L. cotton plant, said method comprising the steps of:growing a transgenic Gossypium hirsutum L. cotton plant to produce mature ovule tissue, wherein cells of said mature ovule tissue comprise in their genome one or more DNA constructs comprising as operably joined components in the direction of transcription, a transcriptional and translational initiation region functional in a cotton ovule integument cell, a DNA sequence encoding an enzyme or polypeptide that increases the biosynthesis of a plant growth hormone that regulates ovary tissue development, and a transcriptional termination region, wherein at least one of said components is heterologous to at least one other of said components, wherein said plant growth hormone is cytokinin, wherein said enzyme is isopentenyl transferase and said DNA sequence is the tmr gene, and wherein said plant expresses said isopentenyl transferase, whereby the rate of boll production and the number of bolls produced by said transgenic Gossypium hirsutum L. cotton plant is increased.
