This system was meticulously studied in Anolis carolinensis, where it shows a highly degenerated Y chromosome and a male-specific X chromosome dosage compensation mechanism. Corytophanids (casque-headed lizards) have been proposed as the only family in the pleurodont clade to lack the XY system. In this study, we worked with extensive genomic and transcriptomic data from Basiliscus vittatus, a member of the Corytophanidae family that inhabits the tropical rainforests of Mexico. We confirmed that B. vittatus underwent a sex chromosome system turnover, which consisted in the loss of the pleurodont XY system and the gain of a new pair of XY chromosomes that are orthologous to chicken chromosome 17. We estimated the origin of the sex chromosome system to have occurred \u223c63\u2009Ma in the ancestor of corytophanids. Moreover, we identified 12 XY gametologues with particular attributes, such as functions related to the membrane and intracellular trafficking, very low expression levels, blood specificity, and incomplete dosage compensation in males.<\/jats:p>","DOI":"10.1093\/gbe\/evz196","type":"journal-article","created":{"date-parts":[[2019,9,5]],"date-time":"2019-09-05T19:25:18Z","timestamp":1567711518000},"page":"2666-2677","source":"Crossref","is-referenced-by-count":25,"title":["Corytophanids Replaced the Pleurodont XY System with a New Pair of XY Chromosomes"],"prefix":"10.1093","volume":"11","author":[{"given":"Armando","family":"Acosta","sequence":"first","affiliation":[{"name":"Center for Genome Sciences, UNAM, Cuernavaca, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Su\u00e1rez-Var\u00f3n","sequence":"additional","affiliation":[{"name":"Laboratorio de Herpetolog\u00eda, Facultad de Ciencias, Universidad Aut\u00f3noma del Estado de M\u00e9xico, Toluca, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis A","family":"Rodr\u00edguez-Miranda","sequence":"additional","affiliation":[{"name":"Biology Institute, UNAM, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s","family":"Lira-Noriega","sequence":"additional","affiliation":[{"name":"CONACYT Research Fellow, Red de Estudios Moleculares Avanzados, Instituto de Ecolog\u00eda, Xalapa, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Aguilar-G\u00f3mez","sequence":"additional","affiliation":[{"name":"Center for Genome Sciences, UNAM, Cuernavaca, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana","family":"Guti\u00e9rrez-Mariscal","sequence":"additional","affiliation":[{"name":"Biotechnology Institute, UNAM, Cuernavaca, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oswaldo","family":"Hern\u00e1ndez-Gallegos","sequence":"additional","affiliation":[{"name":"Laboratorio de Herpetolog\u00eda, Facultad de Ciencias, Universidad Aut\u00f3noma del Estado de M\u00e9xico, Toluca, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fausto","family":"M\u00e9ndez-de-la-Cruz","sequence":"additional","affiliation":[{"name":"Biology Institute, UNAM, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diego","family":"Cortez","sequence":"additional","affiliation":[{"name":"Center for Genome Sciences, UNAM, Cuernavaca, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,9,6]]},"reference":[{"issue":"6209","key":"2019092610313887800_evz196-B1","doi-asserted-by":"crossref","first-page":"646","DOI":"10.1126\/science.1257225","article-title":"Plant genetics.
