Transgenic mulberry plants overexpressing barley Hva1 driven by the actin1 promoter were shown to be drought and salt tolerant. In comparison to non-transgenic plants, transgenic plants demonstrated enhanced proline accumulation, cellular membrane integrity, and photosynthetic production under stress conditions. Transformation of mulberry with hva1 gene from barley for drought and salinity.
BmNPV is a significant silkworm pathogen that mostly infects silkworm larva. The most promising technique for improving resistance is to overexpress antiviral genes in silkworms. Endogenous Bmlipase-1 is a protein that is only found in the midgut of a silkworm. Transgenic silkworm lines with strong resistance to BmNPV were effectively produced by overexpressing an endogenous antiviral gene. The transgenic antiBmNPV line might be used in the sericulture business to reduce silkworm larval mortality. An enzyme called UGT46A1 is an odor degrading enzyme that aids in the breakdown of odor molecules in the silkworm’s olfactory system. The complete amino acid sequence of the silkworm UGT46A1 was utilized to search the NCBI database for homology. Bioinformatics analysis suggests that its function is linked to the silkworm’s feeding patterns and UGT46A1 was discovered to be strongly expressed in the heads of silkworms. The study suggests that UGT46A1 may impact silkworm nutrition by changing the silkworm’s olfactory system.

Recent Global Research Developments in Sericulture: Emerging Trends and Future Prospects
Integration of Advanced Biotechnological Methods: Recent studies emphasize the use of genetic engineering to create silkworm breeds with enhanced traits, such as higher silk yield and improved disease resistance [1].
Sustainable Practices: There is a growing focus on sustainable and organic sericulture practices. Techniques like organic farming of mulberry and eco-friendly silk processing are gaining importance to meet international environmental objectives [1].
Diversification of Silk Applications: Researchers are exploring new applications for silk beyond traditional textiles. This includes medical uses, such as in sutures and tissue engineering, due to silk’s biocompatibility and strength12.
Economic and Environmental Efficiency: Managing and recycling silk waste is being investigated to enhance both economic efficiency and environmental sustainability12.
Preservation of Traditional Practices: While modern technologies are being adopted, there is also an emphasis on preserving cultural and heritage aspects of sericulture. This balance helps maintain traditional practices while adapting to contemporary market demands [1].
