YSL4 and YSL6 are two members of the yellow stripe–like family of metal transporters in Arabidopsis . This study reveals that YSL6 is a protein of the chloroplast envelope, which together with YSL4, is required for the release of iron from the chloroplast. They are active in dedifferentiating chloroplasts of mature embryos and senescent leaves, likely protecting them from free iron toxicity.
