The AAT activity showed no significant change in silk gland with drastic increase in both bodywall and intestine.
Since the silk gland forms the basic organ for cocoon formation and silk production (Krishnaswamy, 1978), probably the synthetic activities of the protein metabolism might have been accelerated through anabolic process by the hormonal treatment, (Bharathi et al.
Scientists in Kessler's and Scheibel's team had last year investigated the common garden spider ("cross spider") to discover the mechanism behind the transition from individual spider silk molecules to connected treads: The individual spider silk proteins are first stored in the silk gland
in small drops called micelles.
Under storage conditions in the silk gland
these control domains are connected pair-wise in such a way that the interlinking areas of both chains can not lie parallel to each other.
We already knew that honeybee silk fibres could be hand-drawn from the contents of the silk gland so used this knowledge to hand-draw fibres from a sufficiently concentrated and viscous mixture of the recombinant silk proteins," she added.
According to Dr Sutherland, numerous efforts have been made to express other invertebrate silks in transgenic systems, but the complicated structure of the silk genes in other organisms means that producing silk outside silk glands is very difficult.

The study of feeding effects with various verities on silk glands
weight showed that silk glands
weight increased in larvae fed on Kokosa at early 5th stage but local varieties had better condition at the end stage, Of course this increase was not significant and cocoon shell weight and males and females shell ratio did not increased.
The production of web decoration is governed by an enhanced activity of the silk glands
and hence physiological processes are expected to impact web decorating behavior (Tso 2004; Walter et al.
The silk starts out as a liquid produced by the spider's silk glands
The spider weaves its golden-colored web from its spinneret, an organ that produces threads of silk from the secretion of silk glands
Tissue glycoproteins of the gut diverticula and the ducts of silk glands
were resistant to diastase digestion and required periodic acid hydrolysis to localize reaction products with the Schiff reagent for aldehydes.
This, says Viney, indicates that the secretions retain a normal fluid structure while inside the silk glands
, but begin to change into a liquid crystal as they exit.
