The pineapple genome and the evolution of CAM photosynthesis

Ray Ming, Robert Paull, Qingyi Yu and colleagues report the genome sequences of two cultivated pineapple varieties and one wild pineapple relative. Their analysis supports the use of the pineapple as a reference genome for monocot comparative genomics and provides insight into the evolution of crassulacean acid metabolism photosynthesis. Pineapple (Ananas comosus (L.) Merr.) is the most economically valuable crop possessing crassulacean acid metabolism (CAM), a photosynthetic carbon assimilation pathway with high water-use efficiency, and the second most important tropical fruit. We sequenced the genomes of pineapple varieties F153 and MD2 and a wild pineapple relative, Ananas bracteatus accession CB5. The…
