silk gland

One of the synapomorphies of spiders is the presence of silk glands situated in the ventral part of opisthosoma (Marples 1967).

"There were so many surprises that emerged from our study: new silk genes, new DNA sequences that presumably confer strength, toughness, stretchiness and other properties to silk proteins; and even a silk protein made in venom glands rather than silk glands," said senior author Benjamin F.

"There were so many surprises that emerged from our study: new silk genes, new DNA sequences that presumably confer strength, toughness, stretchiness and other properties to silk proteins; and even a silk protein made in venom glands rather than silk glands. All this new information should greatly advance our efforts to capture the extraordinary properties of these silks in man-made materials," senior author Benjamin F.

mori larvae at 5th instar (with more developed silk glands) were used.

The AAT activity showed no significant change in silk gland with drastic increase in both bodywall and intestine.

Although differences in the amino-acid sequences in the two regions could account for some of the silks' mechanical properties, it is known that the molecular ordering of the crystalline regions occurs during the flow of liquid silk from the silk glands through the spinnerets (Denny 1980; Kerkam et al.

Spider transcriptomes identify ancient large-scale gene duplication event potentially important in silk gland evolution.

"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.

These threads were as strong as threads drawn from the honeybee silk gland, a significant step towards development of coiled coil silk biomaterials.

Sutherland said that the threads were as strong as threads drawn from the honeybee silk gland. (ANI)

Spiders make silk using their silk glands. Most spiders have five silk glands, and each gland produces a different kind of silk.

Spidroins have a helical and unordered structure when stored as soluble proteins in silk glands, but when converted to silk their structure changes completely to one that confers a high degree of mechanical stability.

For this purpose, the samples of soil, plant, silk glands, silkworm larvae and their excreta were used to determine Cr (III) amount by using Atomic Absorption Spectrometry (AAS).

When a 2006 Nature paper contended that zebra tarantulas had some kind of previously unnoticed silk glands in their feet, the possibility "made quite a splash in the arachnological community," Blackledge recalls.
