Analyzing the Gut Microbiome of Samia cynthia ricini

Abstract

This comprehensive research project delves into the intricate world of the gut microbiota of Samia cynthia ricini (a domesticated native silkworm), shedding light on the profound impact of microbial communities on its growth, health, and phenotypic characteristics. By employing state-of-the-art metagenomic and metabolomic techniques, the study addresses critical objectives. First, it elucidates the composition and dynamics of the gut microbiota under varying dietary conditions and throughout different growth stages. Secondly, it employs shotgun metagenome analysis to uncover the genetic diversity and functional potential of the gut microbiome in the 5th instar larva. Thirdly, it conducts a comparative analysis of the microbiomes of S. cynthia ricini and other lepidopteran species, seeking common patterns and significant differences in taxonomic and functional abundances based on ecological adaptations. Lastly, the study investigates the metabolomic profiles of the silkworm's gut under different dietary regimens and the associated microbiota's role in shaping these profiles.
