Metal accumulation sites in fruits.

ABSTRACT: Global fruit production suffers from pre- and post- harvest losses, part of which are related to metal deficiencies. Despite fruits being one of the most widely consumed plant parts, the spatial distribution of metals and their possible physiological impact remained largely unexplored. In this study, we searched for conserved metal accumulation sites in fruits of various crops and investigated their physiological function. By using X-ray and histochemical-based techniques, we found that calcium accumulated in the outermost hardened tissues, potassium in fleshy tissues, and iron (Fe) in vascular tissues. Furthermore, seeds accumulated Fe in the fruit-seed juncture, which remained in the chalazal part of the seed upon dispersal. In Arabidopsis thaliana, seed chalazal Fe formed a disti
