Abstract
Silkworms (Bombyx mori) have been crucial to silk production for millennia, primarily due to their ability to produce high-quality silk fibers. Recent advancements in biotechnology and genetic engineering have significantly enhanced both silk yield and quality. Traditional breeding methods initially focused on selecting desirable traits like increased yield, improved silk quality, disease resistance, and faster growth. Transgenic silkworms, incorporating genes from other species such as spiders, produce silk with unique properties, including higher tensile strength. New technologies provide comprehensive insights. Future advancements in CRISPR technology, synthetic biology, gene drive systems, AI, and machine learning promise even greater precision and efficiency in genetic modifications. Emerging fields like nanotechnology and epigenetics offer innovative approaches to further enhance silk properties and production methods. The long-term vision for silkworm genetic improvement includes sustainable silk production, integration with various industries, global market leadership, and biodiversity preservation. These advancements aim to position genetic research as a key driver of economic growth and technological innovation in the silk industry, ensuring the production of superior and sustainable silk.
