Conserved domains, phylogenetic analysis, and construct map of AGPAT1. a Schematic distribution of conserved domains in AGPAT1 analyzed by NCBI. b Phylogenetic relationship of AGPAT1 with the known AGPATs from various organisms. The phylogenetic tree was constructed from a complete alignment of 27 proteins MEGA7 using neighbor-joining method. The optimal tree with the sum of branch length = 13.14606879 is presented. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) are represented along the branches. All positions containing gaps and missing data were eliminated. The arrow indicates AGPAT1 of P. tricornutum. c Schematic map of AGPAT1 expression cassette
