摘要

Micronutrients when present in high concentrations can become toxic to plants. Nickel exemplifies this phenomenon, having been considered essential for higher plants since the 1980s. Despite its beneficial effects on seed germination, growth and photosynthesis, an excess of Ni triggers the production of reactive oxygen species, thus exerting harmful effects on physiological and biochemical processes. The literature on this element exists mainly in narrative form, lacking scoping and systematic reviews and meta-analyses, which are crucial for understanding the progression of research in this field over the decades and for conceiving new directions of investigation. To begin to fill this gap, our scoping review, conducted using the PRISMA protocol, aims to outline the plant species under study, methodologies employed, and physiological markers used by peer-reviewed articles published from 2013 to 2022 focusing on the Fabaceae family, taking into account their diversity, economic, social importance and potential for use in phytoremediation programs. Our key findings indicate that Glycine max emerges as the most extensively studied species within the Fabaceae family. Research efforts predominantly target biotic stress, fertilization, and toxicity as primary objectives. However, categories covering physiological data such as nodules, biological nitrogen fixation, carbon metabolism, and gas exchange were underrepresented in the literature.
