Mapping Gene Expression in Two Xenopus Species: Evolutionary Constraints and Developmental Flexibility

Mapping Gene Expression in Two Xenopus Species: Evolutionary Constraints and Developmental Flexibility: "Itai Yanai, Leonid Peshkin, Paul Jorgensen, Marc W. Kirschner. Changes in gene expression are thought to be important for morphological evolution, though little is known about the nature or magnitude of the differences. Here, we examine Xenopus laevis ...."
