Summary Chenopodium quinoa uses epidermal bladder cells (EBCs) to sequester excess salt. Each EBC complex consists of a leaf epidermal cell, a stalk cell, and the bladder. Under salt stress, sodium (Na+), chloride (Cl−), potassium (K+) and various metabolites are shuttled from the leaf lamina to the...
