Ontogeny of this pathway is often studied using species of genus Peperomia, while another common model organism for studying it, Mesenbryanthemum crystallinum, switches to it in response to increased salinity. PCAT-1 is a promoter for the Ppc1 gene transcribed to produce a unique isoform of PEP carboxylase used in this pathway. Unlike a similar pathway, this pathway performs both the fixation and decarboxylation steps in the mesophyll cells, and during it, isocitric and malic acid are shuttled to the vacuole for storage. For 10 points, name this alternative to the C3 and C4 pathways that temporally separates the steps of photosynthesis and is used in plants such as cacti and pineapples.
