Photosynthesis:
C4 and CAM photosynthesis have repeatedly evolved in plants over the past 30 million years. Because both repurpose the same set of enzymes but differ in their spatial and temporal deployment, they have long been considered as distinct and incompatible adaptations. *Portulaca* contains multiple C4 species that perform CAM when droughted. Spatially explicit analyses of gene expression reveal that C4 and CAM systems are completely integrated in *Portulaca oleracea*, with CAM and C4 carbon fixation occurring in the same cells and CAM-generated metabolites likely incorporated directly into the C4 cycle. Flux balance analysis corroborates the gene expression findings and predicts an integrated C4+CAM system under drought. This first spatially explicit description of a C4+CAM photosynthetic metabolism presents a potential new blueprint for crop improvement. – Spatial resolution of an integrated C4+CAM photosynthetic metabolism, Science Advances, DOI: 10.1126/sciadv.abn2349

Conservation:
The truth is that much of what the rest of us know about nature and have incorporated into the various sciences we use to protect it — ecology, zoology, botany, ethnobotany — we learned from the very people we have expelled from the areas we have sought to protect. – The Myth of a Wilderness Without Humans, by Mark Dowie, for The MIT Press Reader
