Combined effects of dosage compensation and incomplete dominance on gene expression in triploid cyprinids

Abstract: Hybridization and polyploidy are pervasive evolutionary features of flowering plants and frequent among some animal groups, such as fish. These processes always lead to novel genotypes and various phenotypes, including growth heterosis. However, its genetic basis in lower vertebrate is still poorly understood. Here, we conducted transcriptome-level analyses of the allopolyploid complex of Carassius auratus red var. (R) (♀) × Cyprinus carpio L. (C) (♂), including the allodiploid and allotetraploid with symmetri… Show more

“…Some phenotypic diversities, such as heterosis, provide us with a useful research resource for investigating their potential mechanisms and could improve agricultural production by engineering breeding [ 6 , 7 ]. Some potential molecular regulatory mechanisms involving genomic [ 8 ] and transcriptomic changes [ 9 , 10 ] have been reported as key factors in shaping heterosis. However, studies on epigenetic modification and post-transcriptional modification are very rare in allotriploids.…”

“…Their distinct morphological characteristics, including body color and shape [ 13 , 14 ], contribute to their extensive adaptability to a diversified environment of slow-moving rivers, lakes, and ponds. Heterosis of the growth trait was observed in the allotriploid complex of common carp and crucian carp [ 7 , 9 ]. Among the two triploids, 3nRC 2 had two sets of subgenome C (originating from common carp) and one set of subgenome R (originating from red crucian carp) [ 7 , 9 ], while 3nR 2 C had one set of subgenome C and two sets of subgenome R [ 7 , 9 ].…”
