abstract = {The biological processes underlying zinc homeostasis are
targets for genetic improvement of crops to counter human
malnutrition. Detailed phenotyping, ionomic, RNA-Seq
analyses and flux measurements with 67Zn isotope revealed
whole-plant molecular events underlying zinc homeostasis
upon varying zinc supply and during zinc resupply to starved
Brachypodium distachyon (Brachypodium) plants. Although both
zinc deficiency and excess hindered Brachypodium growth,
accumulation of biomass and micronutrients into roots and
shoots differed depending on zinc supply. The zinc resupply
dynamics involved 1,893 zinc-responsive genes. Multiple
zinc-regulated transporter and iron-regulated transporter
(IRT)-like protein (ZIP) transporter genes and dozens of
other genes were rapidly and transiently down-regulated in
early stages of zinc resupply, suggesting a transient zinc
shock, sensed locally in roots. Notably, genes with
identical regulation were observed in shoots without zinc
accumulation, pointing to root-to-shoot signals mediating
whole-plant responses to zinc resupply. Molecular events
uncovered in the grass model Brachypodium are useful for the
improvement of staple monocots.},
