Complete mitochondrial genome of the hybrid of Megalobrama terminalis(♀) × Culter alburnus(♂).

ABSTRACT: In this study, we determined the complete mitochondrial DNA sequence of the hybrid of Megalobrama terminalis(♀) × Culter alburnus(♂) for the first time. The complete mitochondrial genome of the hybrid was sequenced to be 16,621 bp in size following the female parent, M. terminalis. The genome contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 2 main non-coding regions (the control region and the origin of light strand replication). Sequence alignment between the mitochondrial genomes of the hybrid and its female parent showed that a total of 28 mutation sites were identified in 14 genes or regions. The genome information presented here may play an important role in further study on the genetic mechanisms of mitochondrial DNA in hybrids.

Complete mitochondrial genome of the hybrid of Culter alburnus (♀) × Megalobrama terminalis (♂).

Project description:In this study, we determined the complete mitochondrial DNA sequence of the hybrid of Culter alburnus (♀) x Megalobrama terminalis (♂) for the first time. The complete mitochondrial genome of the hybrid was sequenced to be 16,622 bp in size following the female parent, C. alburnus. The genome contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and two main non-coding regions (the control region and the origin of light strand replication). Sequence alignment between the mitochondrial genomes of the hybrid and its female parent showed that a total of 35 mutation sites were identified in 14 genes or regions. The genome information presented here may play an important role in further study on the genetic mechanisms of mitochondrial DNA in hybrids.

Unique nucleolar dominance patterns in distant hybrid lineage derived from Megalobrama Amblycephala?×?Culter Alburnus.

Project description:Nucleolar dominance is an epigenetic phenomenon that occurs in interspecific hybrids and involves the expression of 45S rRNA genes inherited from one progenitor due to the silencing of the other progenitor's rRNA genes. In this paper, changes in the genetics and expression of 45S rRNA genes in F1 and F2 hybrid progeny of blunt snout bream (BSB, Megalobrama amblycephala)?×?topmouth culter (TC, Culter alburnus) are investigated.The 45S rDNA loci were analyzed by cloning, RT-PCR and sequencing methods. The results show that nucleolar dominance patterns differ in the F1 and F2 hybrids. In the F1 hybrids of BSB?×?TC, all the tested individuals inherited and expressed the 45S rRNA genes of both BSB and TC, indicating that nucleolar dominance is not established in the F1 hybrids. However, in the F2 hybrids of BSB?×?TC, five patterns are observed. Pattern 1 inherits and expresses only the 45S rRNA gene of BSB. Pattern 2 inherits the 45S rRNA gene from both BSB and TC, but only expresses the 45S rRNA of BSB. Pattern 3 inherits and expresses the 45S rRNA gene from both BSB and TC. Pattern 4 inherits the 45S rRNA gene from both BSB and TC, but only expresses the 45S rRNA gene of TC. Pattern 5 inherits and expresses only the 45S rRNA gene of TC.Nucleolar dominance shows distinctive patterns in intergeneric hybrids of BSB?×?TC. It is not established in F1 hybrids and is random in F2 hybrids. This study provides new insights into the phenomenon of nucleolar dominance in genetic hybrids in vertebrates.

The subgenomes show asymmetric expression of alleles in hybrid lineages of Megalobrama amblycephala × Culter alburnus.

Project description:Hybridization drives rapid speciation by shaping novel genotypic and phenotypic profiles. Genomic incompatibility and transcriptome shock have been observed in hybrids, although this is rarer in animals than in plants. Using the newly sequenced genomes of the blunt snout bream (Megalobrama amblycephala [BSB]) and the topmouth culter (Culter alburnus [TC]), we focused on the sequence variation and gene expression changes in the reciprocal intergeneric hybrid lineages (F1-F3) of BSB × TC. A genome-wide transcriptional analysis identified 145-974 expressed recombinant genes in the successive generations of hybrid fish, suggesting the rapid emergence of allelic variation following hybridization. Some gradual changes of gene expression with additive and dominance effects and various cis and trans regulations were observed from F1 to F3 in the two hybrid lineages. These asymmetric patterns of gene expression represent the alternative strategies for counteracting deleterious effects of the subgenomes and improving adaptability of novel hybrids. Furthermore, we identified positive selection and additive expression patterns in transforming growth factor, beta 1b (tgfb1b), which may account for the morphological variations of the pharyngeal jaw in the two hybrid lineages. Our current findings provide insights into the evolution of vertebrate genomes immediately following hybridization.

The complete mitochondrial genome of the hybrid of Takifugu fasciatus (♀) × T. flavidus (♂).

Project description:In the present study, the complete mitochondrial DNA sequence of the hybrid from Takifugu fasciatus (♀) × T. flavidus (♂) was sequenced and characterized. The genome sequence was 16 443 bp in size, and the gene order and contents were identical with those of congeneric species in the genus Takifugu. Comparing with the complete mitochondrial genome of its parents, the hybrid of T. fasciatus (♀) × T. flavidus (♂) was consistent with a maternal inheritance. All the initiation codons of protein-coding genes are ATG, except for COX1 that begins with GTG. The complete mitogenome of the hybrid of T. fasciatus (♀) × T. flavidus (♂) provides an important dataset for the exploration of mitochondrial inheritance mechanism.

Project description:The hybrid offspring Epinephelus fuscoguttatus ♀ × E. tukula ♂ showed heterosis in terms of growth and disease resistance. The mitochondrial genome is 16,629 bp in length and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. The difference of total length is mainly caused by the difference of length in non-coding region. The nucleotide base composition is A = 29.15%, G = 15.62%, T = 26.91%, C = 28.32%, A + T = 56.06%, and C + G = 43.94%. The phylogenetic analysis using neighbour-joining (NJ) method showed that the hybrid offspring has a closer relationship to E. fuscoguttatus × E. lanceolatus.

Project description:The complete mitochondrial genome of the hybrid grouper Epinehelus moara ♀ × Epinephelus lanceolatus ♂ is presented in this study. The mitochondrial genome is 16,418 bp long and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The gene order and composition of the hybrid grouper mitochondrial genome were similar to that of most other vertebrates. The nucleotide compositions of the light strand in descending order was 28.86% of G, 28.61% of T, 26.46% of A and 16.08% of C. With the exception of the NADH dehydrogenase subunit 6 (ND6) and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. The phylogenetic analysis by maximum-likelihood (ML) method shows that the hybrid grouper has closer relationship to Epinehelus moara and Epinehelus bruneus.
