Abstract

The present invention provides methods for improving cotton fiber quality by modulating transcription factor gene expression.

Claims

exact text as granted — not AI-modified
1 - 26 : (canceled).  
     
     
         27 : A method of modulating transcription in a cotton plant, the method comprising introducing into the cotton plant a recombinant expression cassette comprising a promoter sequence operably linked to a heterologous polynucleotide sequence encoding a cotton MYB polypeptide having at least 95% sequence identity to SEQ ID NO: 8, wherein said cotton MYB polypeptide increases cotton fiber quality.  
     
     
         28 : The method of  claim 27 , wherein the polynucleotide sequence is as shown in SEQ ID NO: 7.  
     
     
         29 : The method of  claim 27 , wherein the polynucleotide sequence encodes a MYB polypeptide as shown in SEQ ID NO: 8.  
     
     
         30 : The method of  claim 27 , wherein the promoter directs expression of the polynucleotide sequence in cotton fibers.  
     
     
         31 : The method of  claim 27 , wherein the modulation of transcription results in alteration of root hairs.  
     
     
         32 : The method of  claim 27 , wherein the promoter sequence directs expression in roots.  
     
     
         33 : A recombinant expression cassette comprising a promoter sequence operably linked to a heterologous polynucleotide sequence encoding a cotton MYB polypeptide having at least 95% sequence identity to SEQ ID NO: 8, wherein said cotton MYB polypeptide increases cotton fiber quality.  
     
     
         34 : The expression cassette of  claim 33 , wherein the polynucleotide sequence is as shown in SEQ ID NO: 7.  
     
     
         35 : The expression cassette of  claim 33 , wherein the polynucleotide sequence encodes a MYB polypeptide as shown in SEQ ID NO: 8.  
     
     
         36 : The expression cassette of  claim 33 , wherein the promoter directs expression of the polynucleotide sequence in cotton fibers.  
     
     
         37 : The expression cassette of  claim 33 , wherein the promoter sequence directs expression in roots.  
     
     
         38 : A cotton plant comprising the expression cassette of  claim 33.
