Chromosome mapping of dragline silk genes in the genomes of widow spiders (Araneae, Theridiidae).
With its incredible strength and toughness, spider dragline silk is widely lauded for its impressive material properties.Dragline silk is composed of two structural proteins, MaSp1 and MaSp2, which are encoded by members of the spidroin gene family.While previous studies have characterized the genes that encode the constituent proteins of spider si
