Understanding the impact of combined stresses on photosynthesis, as occurs in nature, is likely a crucial strategy to increase crop productivity sustainably. Water and salt stresses, excess light, changes in temperature and nutritional requirements, and the co-occurrence of biotic stresses are integrated factors that are translated into complex responses adopted by plants. The subsequent adjustments are generally aimed at the efficient allocation of energy resources, plant survival, and offspring creation. In this aspect, plants have co-existed with these natural phenomena for millions of years. Their immense phenotypic plasticity guarantees effective adaptation and survival to a wide range of environmental variations, including the projected global climate changes. We humans, on the other hand, relying on few crops as our main food source, find ourselves in a more precarious situation in this chain of events. Indeed, we are already threatened by increasingly extreme weather events observed in the present. Starting from the premise that early knowledge is the only way to assure global food security in the short, medium, and long term, we set out to ask the following: what do we actually know about the photosynthetic mechanisms of plants in a systemic context (Lima Neto et al., 2021) that allows us to increase the crop yield, nutritional value, and/or land-use efficiency under field conditions?
