Malic enzyme, an “old-new player” in age at maturity in Atlantic salmon
Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG Traditional genetic markers based on allozyme variation had indicated that in Atlantic salmon the genetic variation found for the locus coding for mMEP-2* could be adaptive, with the variation being related to river water tempe...

We found a relationship between the presence of SNP G, equivalent to the 125* allele, and early maturation of Atlantic salmon in both males and females. It is possible that the relationship between the different alleles of this locus and maturation is not direct but is produced by differential growth during the juvenile and/or adult phase. It is also plausible that this association is exclusive to the salmon populations of the Iberian Peninsula. Xunta de Galicia | Ref.
