General Information

General Information Comment Organism
additional information Plants that overexpress GhXTH1 have increased XTH activity and produce mature cotton fibers that are between 15 and 20% longer than wild-type cotton plants under both greenhouse and field growth conditions Gossypium hirsutum
physiological function plant cell wall extensibility is mediated, in part, by xyloglucan endotransglycosylases/hydrolases, XTH, that are able to cleave and reattach xyloglucan polymers that make up the hemicelluloses matrix of type I cell walls. The three GhXTH genes are expressed differently with GhXTH1 predominantly expressed in elongating cotton fibers, function of GhXTH1 in mediating cotton fiber elongation, the 35S::GhXTH1 transgene acts as a dominant fiber length allele in transgenic cotton, overview Gossypium hirsutum
