The Yellow Stripe-Like (YSL) family of proteins are transporters of metal-phytosiderophore and metal-nicotianamine complexes. Information concerning their physiological role(s) is critical for understanding metal homeostasis on the whole-plant level. By comparative genomics analysis of the YSL family from Brachypodium distachyon, maize and rice, Yordem et al. establish the existence of a highly conserved clade within [...]
