Microalga, Nannochloropsis oculata, is an important microorganism for feeding fish larvae. We develop a transgenic line of N. oculata that enbles to produce an antimicrobial peptide, bovine lactoferricin (LFB). An algae-codon-optimized cDNA of LFB was fused with a red fluorescent protein (DsRed) reporter and driven by a heat-inducible promoter, which is a heat shock protein 70A promoter combine...
