several abundant XTH genes are generally up-regulated during tension formation, including XTH16-36, -21, -14 and -27, while others were suppressed such as XTH16-35. In mature gelatinous fibers, enzyme gene products are detected in the gelatinous layers while the enzyme's endo-transglycosylase activity is found in the adjacent S2 wall layer. Enzyme gene products and activity persist in mature gelatinous fibers for several years |
