Comparative transcriptomic and metagenomic analyses reveal key factors affecting the growth rate of Red Swamp Crayfish (Procambarus clarkii)

Even under highly-controlled growth conditions, sibling individuals of red swamp crayfish (Procambarus clarkii) frequently exhibit stunting. To elucidate the causes of stunting, we compared the hepatopancreas transcriptome and intestinal flora of sibling crayfish. Individual variations were investig...

Description
Summary:Even under highly-controlled growth conditions, sibling individuals of red swamp crayfish (Procambarus clarkii) frequently exhibit stunting. To elucidate the causes of stunting, we compared the hepatopancreas transcriptome and intestinal flora of sibling crayfish. Individual variations were investigated, and the association of gut bacterial community function with host transcriptome function was explored. A total of 60,637,958 single genes were assembled from 300,691,028 high-quality reads. When the expression patterns of crayfish hepatopancreas of various sizes were compared, 497 differentially expressed genes (P
