Abstract

C4 plants are integral to many ecosystems around the world and are abundantly found in grasslands and savannas in North America, Australia, and Africa, and deserts in Central Asia among other ecosystems in and around Europe (Edwards and Still 2008; Pyankov et al. 2010; Rudov et al. 2020; Wan et al. 2001). Despite making up 20% of the global plant biomass (Ehleringer et al. 1997), our understanding of C4 physiology and biochemistry still has room for improvements. More specifically, the three subtypes of C4 plants (NADP-malic enzyme, NAD-malic enzyme, and PEP carboxykinase) should be better characterized in terms of their biochemistry. To do that, we require a comprehensive characterization of species from across C4 families, not just model C4 species. However, it is often labor-intensive to collect the full gamut of physiological and biochemical data for large numbers of species. Here, I describe a hierarchical Bayesian approach in parametrizing the C4 photosynthesis model that can estimate biochemical parameters using gas exchange data while accounting for plant, species, and subtype variation.
