Cover Story (view full-size image): Phytic acid is an antinutritional compound that reduces mineral bioavailability from the diet. The development of low phytic acid (lpa) mutants has been an important goal for nutritional seed quality improvement. Some lpa mutations affect genes coding for three classes of transporters: a specific group of ABCC type phytic acid vacuolar transporters, putative sulfate transporters, and a phosphate transporter. In the present review, we summarize advances in the characterization of these transporters in cereals and legumes. We comment on the advantage of using such types of mutants for crop biofortification and on their possible utility to unravel links between phosphorus and sulfur metabolism. View this paper
