摘　　要：This review provides an examination of the marsh spot disease in beans and the roles played by its causal factor, manganese (Mn) deficiency. The discovery of the marsh spot disease, its relation with Mn deficiency, and how it can be treated are discussed. Mn serves as a cofactor and a catalyst in various metabolic processes in different cell compartments, such as the oxygen-evolving complex of photosystem II (PSII) or reactive oxygen species scavenging. Some major quantitative trait loci (QTL) and putative candidate genes associated with Mn content in plants, especially in plant seeds, have been identified. Marsh spot disease in cranberry common bean is controlled by several major genes with significant additive and epistatic effects. They provide valuable clues for QTL candidate gene prediction and an improved understanding of the genetic mechanisms responsible for marsh spot resistance in plants.This review provides an examination of the marsh spot disease in beans and the roles played by its causal factor, manganese (Mn) deficiency.
