摘要:
Provided are two plant cDNA clones that are homologs of the bacterial CelA genes that encode the catalytic subunit of cellulose synthase, derived from cotton (Gossypium hirsutum). Also provided are genomic promoter regions to these encoding regions to cellulose synthase. Methods for using cellulose synthase in cotton fiber and wood quality modification are also provided.
摘要:
This invention relates to an isolated nucleic acid fragment encoding a cellulose synthase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the cellulose synthase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the cellulose synthase in a transformed host cell.
