We propose the sequencing of 9 chordate species to complete the coverage of all major nodes of chordate evolution with at least two sequenced species. These include; 1. Reptile 1: Alligator mississipiensis (2.5 Gb genome), the American alligator, for high quality draft genomic sequence (approx. 6x) plus ESTs. 2. Reptile 2: Chrysemys picta (2.6 Gb genome), the painted turtle, for high quality dr...
