Farfantepenaeus gene-encoded antimicrobial peptides: Identification, molecular characterization and gene expression in response to fungal infections

•The four shrimp AMP families are present in species of Farfantepenaeus.•Farfantepenaeus AMPs form diverse gene families composed by different members.•Most AMPs from F. paulensis shrimp are constitutively expressed by circulating hemocytes.•F. paulensis AMPs are differentially modulated in response to a fungal infection.
