Team at Southwest University improves silk by genetic engineering

The group of XIA Qingyou at the university’s laboratory of silkworm genomic biology modified the mechanical properties of silk by overexpressing ER-type calcium ion ATP synthase, the secondary structure of silk fibers can be changed, thereby substantially increasing silk fiber strength, elongation, toughness and elastic modulus.
