Title AhNAS2 suppression in Arabidopsis halleri roots
Platform organism Arabidopsis thaliana
Sample organism Arabidopsis halleri
Experiment type Expression profiling by array
Summary The model Zn hyperaccumulators Arabidopsis halleri and Noccaea caerulescens share elevated nicotianamine synthase (NAS) expression relative to non-accumulators among a core of alterations in metal homeostasis gene expression. Suppression of AhNAS2 expression by RNAi resulted in strongly reduced root NA accumulation and a concomitant decrease in root-to-shoot-translocation of Zn but not of other micronutrients. Few secondary effects on the root transcriptome were detected by microarray analysis.
Overall design Vegetatively propagated clones of A. halleri wildtype plants and a line with strong suppression of AhNAS2 were grown hydroponically for weeks in two different media (control Hoagland and 10 ┬ÁM Zn2+ added). Roots were harvested and analyzed. Three plants were pooled for one sample. Three independent experiments were performed.
