Diel dynamics of multi-omics in elkhorn fern provide new insights into weak CAM photosynthesis.

ABSTRACT: Crassulacean acid metabolism (CAM) has high water-use efficiency (WUE) and is widely recognized to have evolved from C₃ photosynthesis. Different plant lineages have convergently evolved CAM, but the molecular mechanism that underlies C₃-to-CAM evolution remains to be clarified. Platycerium bifurcatum (elkhorn fern) provides an opportunity to study the molecular changes underlying the transition from C₃ to CAM photosynthesis because both modes of photosynthesis occur in this species, with sporotrophophyll leaves (SLs) and cover leaves (CLs) performing C₃ and weak CAM photosynthesis, respectively. Here, we report that the physiological and biochemical attributes of CAM in weak CAM-performing CLs differed from those in strong CAM species. We invest
