Illumina sequencing of O. chalcidica and A. arenosa.
We hypothesized that microorganisms may enhance metal uptake by modulating the expression patterns of plant metal transporters. To test this, we compared the root transriptomes (RNA-seq) of in vitro- cultured Odontarrhena chalcidica and Arabidpsis arenosa, either inoculated with a serpentine-soil microbial extract or left uninoculated.
