Tree View of All Chemosensory Receptor Genes in the Sra Subfamily
C. elegans is shown in white background andC. briggsae in light blue background. The arrows indicate regions ofC. elegans-specific expansion of the family. The inset shows a schematic of the region ofC. elegans chromosome I corresponding to the sra expansion in the upper right of the tree.C. briggsae genes are named using the prefix CBG, whileC. elegans genes are numbered consecutively across the cosmid on which they were first identified. The root of this tree is arbitrary.
