The parallel reaction monitoring assays in heterosis of hybrid yellow catfish Huangyou-1

Heterosis is a complex biological phenomenon in which hybridization exhibits superior phenotypic characteristics. The underlying molecular basis for heterosis, particularly for fishes, remains elusive. The utilization rate of fish heterosis far exceeds our understanding of it on a theoretical level. To gain a comprehensive and unbiased molecular understanding of fish heterosis, we characterized mRNA-seq, miRNA-seq, and proteomes of Pelteobagrus fulvidraco, P. vachelli, and the hybrid yellow catfish Huangyou-1 (P. fulvidraco ♀×P. vachelli ♂) livers using next-generation sequencing technologies and tandem mass tags. Our results show that the nonadditive
