Uncovering the transcriptional response of popcorn (Zea mays L. var. everta) under long-term aluminum toxicity

Abstract To date, the investigation of genes involved in Al resistance has focused mainly on microarrays and short periods of Al exposure. We investigated genes involved in the global response under Al stress by tracking the expression profile of two inbred popcorn lines with different Al sensitivit...
