Summary

Although significant advances have been achieved in the biofortification of common beans to overcome deficiencies in Zinc (Zn) and iron (Fe), the mechanisms involved remain poorly understood. We thus explored the relationships between phosphorus nutrition and Zn and Fe accumulation in four bean genotypes (Edar, Nizok, Colorado and Chimbolos) that nominally show differences in seed Fe and Zn accumulation. In contrast to other genotypes, while phosphorus availability had no effect on seed Fe accumulation, phosphorus and phytate levels were decreased in all lines under phosphorus deficiency. Edar plants had a higher seed yield under low phosphorus conditions than the other lines. Analysis of the seed proteome also revealed that Edar is highly resistant to phosphorus deficiency, with similar s
