Polyploidization and pseudogenization in allotetraploid frog Xenopus laevis promote the evolution of aquaporin family in higher vertebrates

摘要

Synteny analysis between the homeologs in X. laevis and X. tropicalis genome. The linkages between the AQP genes were marked with red lines. Genome location and gene structure of the AQP genes in X. laevis genome were shown beside the chromosomes. The wedges colored in violet and yellow represent the exon regions in AQP genes. Different color represents the different encoding direction. The shrinked lines represent the intron regions
