Nitrate transport and assimilation in Aspergillus nidulans [PDF]

open access: yes, 2012
In this study, several aspects of nitrate assimilation and transport have been studied using the filamentous fungus Aspergillus nidulans, which has been shown to be safe laboratory organism as judged by it’s pathogenicity towards insect larvae.
