[‚kras·ə¦lā·shən ¦as·əd mə′tab·ə‚liz·əm]

A type of photosynthesis exhibited by many succulent plants in which carbon dioxide is taken up and stored during the night to allow the stomata to remain closed during the daytime, decreasing water loss. Abbreviated CAM.

In these genera there is further evidence, beyond just the [Delta][H.sup.+] reports, that points to CAM photosynthesis (Section V).
Scientists are studying a variety of drought-resistant plants to unlock the mystery of CAM photosynthesis. For this work, the ORNL-led team sequenced the genome of KalanchoE1/2 fedtschenkoi, an emerging model for CAM genomics research because of its relatively small genome and amenability to genetic modification.
Bromeliads appear to have begun invading drier areas in Central and South America beginning roughly 15 million years ago, at the same time as bromeliads underwent a major adaptive radiation involving the repeated evolution of epiphytism, CAM photosynthesis, impounding leaves, several features of leaf and trichome anatomy, and an accelerated rate at which new genera subsequently appeared.
