Plant Sulfate Transporters in the Low Phytic Acid Network: Some Educated Guesses.
Gian Attilio SacchiFabio Francesco NocitoPublished in: Plants (Basel, Switzerland) (2019)
A few new papers report that mutations in some genes belonging to the group 3 of plant sulfate transporter family result in low phytic acid phenotypes, drawing novel strategies and approaches for engineering the low-phytate trait in cereal grains. Here, we shortly review the current knowledge on phosphorus/sulfur interplay and sulfate transport regulation in plants, to critically discuss some hypotheses that could help in unveiling the physiological links between sulfate transport and phosphorus accumulation in seeds.
