PurposeTo identify the fatty acyl-CoA reductase (far) gene family and to analyze the gene sequences.
MethodThe far gene family of the Chinses white wax scale insect (Ericerus pela) was identified and analyzed by bioinformatics methods.
ResultsThere were a total of 30 candidate far genes were identified, and 22 genes of them had a relatively conserved structure, an NAD(P)H binding domain and a FAR C domain. Motif analysis showed that there were 13 conserved motifs in these FAR. The far genes of E. pela had 6-11exons and 5-10 introns. The phylogenetic analysis showed that FAR of E. pela were divided into two groups. The phylogenetic tree based on FAR of different species revealed FAR cluster groups closely related to species rather than their functions. Synteny analysis and amino acid similarity analysis showed that FAR generally had the highest similarity within the same species.
ConclusionThis study was helpful to understand the evolution of far gene family in E. pela and provided a basis for further research on the molecular functions of far gene family of E. pela.
