The hepatopancreas and ovary are the sites of vitellogenin synthesis in female red swamp crayfish (Procambarus clarkii (Girard, 1852)) (Decapoda: Astacoidea: Cambaridae) [PDF]

open access: yesJournal of Crustacean Biology, 2016
Vitellogenin (Vg) is the precursor of vitellin, the major yolk protein. The site of Vg synthesis in crustaceans remains controversial. This study investigated the synthesis site of Vg in female red swamp crayfish Procambarus clarkii (Girard, 1852). Results revealed that the mRNA of Vg was detected in the tissues of hepatopancreas of P. clarkii . The
