Voight's team also examined gene transcripts from different orb-weaver silk glands
and in each case found transcripts belonging to more than one spidroin class, suggesting that these glands are not strictly specialized for producing one type of silk.
The larvae silk glands
were removed and homogenized in 150 [micro]L of the extraction solution (2-mercaptoethanol 0.
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.
The araneoids have six functional spinnerets and six different kinds of silk glands
each producing one to three types of protein (Kovoor 1987; Coddington 1989).
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 silkworm larvae from all the five instars, excreta leaves and silk glands
were used for AAS analysis.
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.
Since several types of silk glands
are remodeled during a molt, they may not be fully operative in the days immediately after the molt (Townley 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.
