Abstract
- Although many researches have revealed that liquid phase of silk in the ampulla is turning into the polymerized dragline silk fibers as the feedstock passes through the long duct, the exact mechanism has still been not fully understood. Spider's strongest silk fiber, dragline, is mainly produced in the large ampullate glands, the biggest silk gland in the abdomen with a distinctive yellow color. Morphologically, the duct of large ampullate gland is in its unique S-shape with 2 loops dividing the entire duct into three limbs. In addition, the diameter of the duct showed radical decrease toward the nozzle of the duct. Therefore, it assumed that the duct is playing a significant role in the entire process of silk production allowing great strength. Here, we present some of the fine structural properties of the large ampullate gland duct in Nephila clavata using various visualizations techniques. [ABSTRACT FROM AUTHOR]
