Plant Proteins Responsible for Fiber Strength in Cotton
Apr 19, 2019


Enzymes and proteins of two lines of cotton differing in fiber strength were studied. The study revealed that activity of glucan synthetase and peroxidase in these lines increased with maturity, while the activity of B-(1-3)-glucanase and cellulase decreased. Specific enzymatic activity of peroxidase and glucan synthetase in line L-175 was higher than that in line L-466 characterized by lower fiber strength. The activity of glucanase decreased in relation to fiber strength. On investigating the water soluble protein fraction of cotton fiber, polypeptides with molecular weights of 28 and 39 kD were found and associated with fiber strength
