The <i>Carassius</i> complex of cyprinid teleosts contains sexual tetraploid crucian carp/goldfish (<i>C. auratus</i>) and unisexual hexaploid gibel carp/Prussian carp (<i>C. gibelio</i>) lineages, providing a valuable model for studying the evolution and maintenance mechanism of unisexual polyploids in vertebrates. Here we sequence the genomes of the two species and assemble their haplotypes, which contain two subgenomes (A and B), to the chromosome level. Sequencing coverage analysis reveals that <i>C. gibelio</i> is an amphitriploid (AAABBB) with two triploid sets of chromosomes; each set is derived from a different ancestor. Resequencing data from different strains of <i>C. gibelio</i> show that unisexual reproduction has been maintained for over 0.82 million years. Comparative genomics show intensive expansion and alterations of meiotic cell cycle-related genes and an oocyte-specific histone variant. Cytological assays indicate that <i>C. gibelio</i> produces unreduced oocytes by an alternative ameiotic pathway; however, sporadic homologous recombination and a high rate of gene conversion also exist in <i>C. gibelio</i>. These genomic changes might have facilitated purging deleterious mutations and maintaining genome stability in this unisexual amphitriploid fish. Overall, the current results provide novel insights into the evolutionary mechanisms of the reproductive success in unisexual polyploid vertebrates.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Comparative genome anatomy reveals evolutionary insights into a unique amphitriploid fish","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-09-09","DateCreate":"2022-09-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000825839600001","VABBcode":null,"OpenAcc":0,"DOI":"10.1038/s41559-022-01813-z"},"refs":null,"anarec":{"AnaID":355342,"PubliDate":2022,"Pagination":"1354-1366","XtraPublOfAnaID":null,"ISBN":null,"Volume":"6","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":282823,"SerRR":"Nature Ecology & Evolution.
