IMA peptides are dwarf giants fighting for fitness.

ABSTRACT

IRON MAN (IMA) peptides have a critical role in iron uptake and homeostasis, but whether and how they associate with plant immunity signaling remain unclear. Recently, Cao et al. provided intriguing insights into the underlying plant mechanisms that restrict root iron acquisition on perception of microorganism-associated molecular patterns (MAMPs) by spatial IMA-1 turnover.
