Abstract

V originále

Interspecific hybrids of F1 generations have frequently been characterized by high vigour resulting from heterosis advantage. In contrast, post-F1 generations are expected to express hybrid breakdown, i.e., they suffer from low viability and survival, reproductive abnormalities or sterility and limited ecological performance. Resistance or susceptibility to parasites is one of the measures reflecting hybrid vigour. The present study aimed to analyse the experimental infection of the blood-feeding generalist parasite Paradiplozoon homoion (Monogenea) in two target fish species, Abramis brama and Rutilus rutilus, and their reciprocal F1 hybrids and backcross hybrids, and to reveal potential parasite-induced changes in their transcriptome profiles of head kidney. We hypothesized various effects of hybridization in terms of parasitism in F1 hybrids and backcross hybrids reflected by differential gene expression. The number of differentially expressed genes (DEGs) differed between fish lines with a lower number of DEGs in F1 hybrids and a higher number in backcross hybrids when compared to the parental lines, A. brama and R. rutilus. Backcross hybrids were more infected than F1 hybrids and parental lines. DEG analyses revealed the role of heme binding, erythrocyte differentiation and immunity-related processes in fish after infection by blood-feeding P. homoion. Using GO and KEGG analyses, we revealed the similarity in DEGs between two backcross generations of hybrids. This finding may indicate a potential consequence of hybrid breakdown in backcross generations. Gene expression in less parasitized F1 hybrids is in line of hybrid advantage.
