Endosperm prevents toxic amounts of Zn from accumulating in the seed embryo – an adaptation to metalliferous sites in metal-tolerant Biscutella laevigata
Résumé
The pseudometallophyte Biscutella laevigata adapts to metalliferous soils by allocating excess metal(loid)s to the endosperm (E) of seeds to protect embryonic tissues and improve reproductive success.
