Abstract | Phosphoacetyl glucosamine mutase (PGM) is the key gene for glycolysis of important metabolic pathways in silkworm, and H₂S (7.5 μM) can promote the growth and development of silkworm. Herein, we used body cavity injection of small‐interfering RNA (siRNA) to interfere with the PGM gene in H₂S‐treated silkworms. After RNA interference (RNAi), we investigated the growth and development of the silkworm. H₂S treatment could significantly recover the inhibition of body weight, cocoon weight, cocoon shell weight, and cocoon shell ratio by knocking down PGM gene in silkworm, without significant effects on eggs laying and production, and then analyzed the mRNA expression of PGM gene. The interference of siRNA significantly decreased the expression of targeted PGM gene and was concentrated in 48 h followed by gradual recovery. Three interference fragments also showed different interference effects, and siRNA of PGM‐3 exerted the highest interference effect to the target gene expression. Fat body had the highest mRNA expression of PGM gene, and the best interference effect was observed after siRNA injection. The results showed that the gene based on H₂S treatment may have an important impact on the growth and development of silkworm by affecting its metabolic pathway. |
