Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, the caterpillar of the domestic silkmoth is the most widely used and intensively studied silkworm.
Spider silk structure: crystalline beta-sheets separated by amorphous linkages. Silks have a hierarchical structure. The primary structure is the amino acid sequence of its proteins (), mainly consisting of highly repetitive glycine and alanine blocks, [4] [5] which is why silks are often referred to as a block co-polymer.
Sericulture or silk farming — the cultivation of silkworms to produce silk in the silk production process. Subcategories.
Spiders make spider silk for various purposes such as weaving their webs, protecting their eggs or as a safety line. The amphipod Peramphithoe femorata uses silk to make a nest out of kelp blades. Another amphipod, Crassicorophium bonellii, use silk to build shelter. Carp produce fibroin units, a component of silk, to attach their eggs to rocks ...
A magnanery (French: magnanerie) is the site of sericulture, or silk farming, similar to a farm being the site of agriculture. The yeoman who runs it is called a magnanier or, more recently, a mangnan. The word magnanière, meaning building dedicated to sericulture, is also seen.
Silk proteins present in other spider silk types are also occasionally referred to as spidroin. These include tubuliform silk protein (TuSP), flagelliform silk protein (Flag; O44358 - Q9NHW4 - O44359 ), minor ampullate silk proteins (MiSp; K4MTL7 ), aciniform silk protein (AcSP), pyriform silk protein (PySp) and aggregate silk glue (ASG2/AgSp).
The silk generated by the male P. mira is rather versatile; when courting a female nursery web spider, the male spider offers her a "nuptial gift," usually a prey wrapped up in the male's silk. This act of gift-giving serves as the first stage of mating, preceding copulation.
Since spider silk has a variety of potential uses, including in fabrics and biomedical technologies, the sequence motifs for genes coding for this silk in the species have been studied to examine the potential for artificial production. In the study by Lee et al., clones of the genes for this silk were produced and injected into insect cells to ...
