Multi-omics reveals glycolipid metabolism processes during the early development of largemouth bass (Micropterus salmoides)

The largemouth bass (Micropterus salmoides) is one of the most valuable freshwater farmed fish in China, whose production involves a lot of energy consumption. However, the genetic regulation of energy metabolism in largemouth bass early development remains unclear. Herein, combined transcriptome and metabolome analyses were carried out for six early developmental stages: blastocyst, gastrulation, hatching, 1 day post hatching (dph), 2 dph, and 3 dph. Early embryos' yolk and oil droplet diameters decreased significantly with embryonic development (P
