Time series analysis of transcriptomic responses to iron and zinc stress in Poplar

Iron (Fe) and zinc (Zn) are indispensable cofactors for critical aspects of plantgrowth including numerous metabolic pathways, post-translational modifications, cell-wall biosynthesis, and carbon/nitrogen assimilation.We aim to investigate transcriptional changes under limiting, normal and excess Iron and Zinc stress in leaf and root tissues of a bioenergy feedstock model plant western poplar (Populus trichocarpa accession Nisqually-1).
