干扰抑制

Several studies have indicated that SuSy performed a very important role during the fiber initiation and elongation. Furthermore, down-regulation of SuSy mRNA levels in the cotton ovular epidermis by RNAi leads a fiber-less phenotype.Efforts to understand and manipulate fiber development would be enhanced by an improved knowledge of the promoter elements and transcription factors that regulate fiber relative gene expression.
