Identification and application of cotton gene BZR1
InactiveCN103981193AEnhanced interactionReduce protrusionPlant peptidesFermentationFunctional identificationADAMTS Proteins
The invention relates to cloning and functional identification of a gene GhBZR1 for preferential expression of cotton fibers. The gene GhBZR1 is 1410bp in overall length and is coded with a protein containing amino acid 313. If a large amount of mRNA (messenger Ribonucleic Acid) of the gene GhBZR1 is accumulated in cotton fiber cells during a stretching development stage, the gene GhBZR1 is considered as a fiber preferential expression gene. The protein GhBZR1 is positioned in a cytoplasm and a cell nucleus, and is accumulatively increased in the cell nucleus after being induced by BL (Butyrolactone). The protein GhBZR1 can interact with a protein GhBIN2 and can be phosphorylated by the protein GhBIN2, thereby promoting the interaction carried out between the protein GhBZR1 and a protein 14-3-3. Thus, if the over-expression of the GhBZR1 is carried out in a mutant bri1 of arabidopsis BR, the scrubby phenotype of the arabidopsis BR can be restored. If the expression of the gene GhBZR1 in the cotton is inhibited by utilizing an RNAi (Ribonucleic Acid interfere) technique, the development of ovules and fibers of a transgenic cotton plant is apparently affected. Thus, the result speculates that the cotton fiber development and the fiber quality character are regulated by the gene GhBZR1 possibly in a manner of influencing a BR signal.
