摘要： The liver-type fatty acid binding proteins (L-FABP) gene in golden pompano Trachinotus ovatus larvae was cloned in the present study. The full length of L-FABP cDNA from golden pompano was 604 bp, including a 5'-untranslated region (UTR) of 154 bp, a 3'-UTR of 69 bp and an open reading frame (ORF) of 281 bp. L-FABP encoding a polypeptide of 126 amino acids with a predicted molecular weight of 14.06 kDa and a theoretical isoelectric point of 8.73. The results of qRT-PCR showed that the highest tissue expression of L-FABP gene was observed in fish liver on 18 DPH. Along with the ontogeny of fish larvae, the expression of L-FABP gene was low at hatching, and quickly increased with the increase of fish age from 0 DPH to 4 DPH, and reached the highest level on 12 DPH. The highest expression of L-FABP gene was observed in fish cultured at 29 degrees C on both 12 DPH and 18 DPH (P<0.05). Nutrition enhancement significantly affected the expression of L-FABP gene, the highest expression was observed in the Algamac 3080 treatment, and lowest expression was observed in the Nannochloropsis treatment. This study provides useful information on the functional mechanism of L-FABP gene in the ontogenetic development of golden pompano.
