| Outline of Final Research Achievements |
The present study aimed to elucidate the genetic basis associated with niche shifts to different temperature environments using Anolis lizards. The genomes of six species inhabiting hot-open and cool-forest habitats were sequenced to detect genes involved in temperature adaptation through genome analysis comparisons. The results of the genome analysis showed that species inhabiting hot-open habitat have higher rates of gene duplication. In addition, conserved and accelerated evolutionary genomic regions were detected in species with hot-open and cool-forest habitats. The results show that these genes predicted to be involved in circadian rhythms, visual development and genes related to lipid metabolism. The gene expression analysis indicated that high TRPV1 expression levels are maintained in lower temperature-preferring species compared to other species.
