Groundwater with high arsenic (As) concentration constitutes a serious problem for crops, sinceroots can accumulate the metalloid acting as the first stage of As distribution in the trophic chain. The aim ofthis research was to elucidate the impact of a realistic As(V) dose in peanut and maize plants and to determinethe contribution of plant growth promoting bacteria (PGPB) to metalloid translocation in both crops. The resultsobtained revealed that rhizoinoculation of plants exposed to metalloid, contributed not only to improve growthbut also to reduce As transport to shoots. Hence, inoculation of peanut and maize with the correct PGPB partnerprevents metalloid translocation in plants avoiding possible fruit contamination.
