Polynucleotides and polypeptides involved in plant fiber development and methods of using same

摘要

Isolated polynucleotides are provided. Each of the isolated polynucleotides comprise a nucleic acid sequence encoding a polypeptide having an amino acid sequence at least 80 % homologous to SEQ ID NO: 26, 106, 107, 109, 110, 112, 114, 115, 118, 119, 122, 123, 124, 126, 95 or 96, wherein the polypeptide is capable of regulating cotton fiber development. Also provided are methods of using such polynucleotides for improving fiber quality and/or yield of a fiber producing plant, as well as methods of using such polynucleotides for producing plants having increased biomass/vigor/yield.
