VIN activity in elongating fibers is approximately 4-6fold higher than that in leaves, stems, and roots. It is undetectable in fiberless cotton seed epidermis but becomes evident in initiating fibers and remains high during their fast elongation and drops when elongation slows. A genotype with faster fiber elongation has significantly higher fiber VIN activity and hexose levels than a slow-elongating genotype |
