In addition, we compared the gene sequences in transcriptomes of four oviparous-viviparous pairs of lizards in different genera ( Phrynocephalus, Eremias, Scincella, and Sphenomorphus) to look for possible gene convergence at the sequence level. We found changes in expression patterns of appropriate genes that account for each of the major aspects of the oviparity to viviparity transition. Expression patterns of maternal oviduct through reproductive development of the egg and embryo differ markedly between the two species. We performed genomic and transcriptomic analyses of a closely related oviparous-viviparous pair of lizards ( Phrynocephalus przewalskii and Phrynocephalus vlangalii) to examine these transitions. The transition from oviparity to viviparity requires numerous physiological, morphological, and immunological changes to the female reproductive tract, including eggshell reduction, delayed oviposition, placental development for supply of water and nutrition to the embryo by the mother, enhanced gas exchange, and suppression of maternal immune rejection of the embryo. Over two-thirds of these changes in vertebrate reproductive parity mode happened in squamate reptiles, where the transition has happened between 98 and 129 times. ![]() Viviparous (live-bearing) vertebrates have evolved repeatedly within otherwise oviparous (egg-laying) clades. 9 Department of Integrative Biology and Biodiversity Center, University of Texas at Austin, Austin, TX 78712 10 Jiangsu Key Laboratory for Biodiversity and Biotechnology, College of Life Sciences, Nanjing Normal University, 210023 Nanjing, Jiangsu, China 11 State Key Laboratory of Genetic Resources and Evolution, Kunming Institute of Zoology, Chinese Academy of Sciences, 650223 Kunming, China 12 Southeast Asia Biodiversity Research Institute, Chinese Academy of Sciences, Yezin, 05282 Nay Pyi Taw, Myanmar.8 Section for Ecology and Evolution, Department of Biology, University of Copenhagen, DK-2100 Copenhagen, Denmark.7 School of Life Science and Technology, ShanghaiTech University, 201210 Shanghai, China.6 Jiangsu Key Laboratory for Biodiversity and Biotechnology, College of Life Sciences, Nanjing Normal University, 210023 Nanjing, Jiangsu, China.5 Center for Excellence in Animal Evolution and Genetics, Chinese Academy of Sciences, 650223 Kunming, China.4 Key Laboratory of Systems Biology, Center for Excellence in Molecular Cell Science, Institute of Biochemistry and Cell Biology, Chinese Academy of Sciences, University of Chinese Academy of Sciences, 200031 Shanghai, China.3 China National Genebank, Beijing Genomics Institute-Shenzhen, 518083 Shenzhen, China. ![]()
