Comparing orthologs in two Yucca species to discover divergence in the expression patterns of genes involved in crassulacean acid metabolism (CAM).

Through the process of neofunctionalization, gene roles often differ between two species after divergence from their last common ancestor. These new roles may be the result of changes to the amino acid sequence or a change in the spatiotemporal expression pattern.1 We use comparative genomics to investigate how genes involved in crassulacean acid metabolism (CAM) have diverged between two closely related Yucca species: Y. aloifolia, a CAM species, and Y. filamentosa, a C3 species. Here, we present the results of a preliminary analysis to determine which canonical CAM genes (Fig. 3) in Y. aloifolia exhibit diverged expression patterns compared to Y. filamentosa. We used gene family circumscription and expression pattern clustering methods to make comparisons between orthologous sets of genes.
