That deregulation in nitrate reductase gene expression could possibly have been due to a modified transcription rate for the nitrate reductase gene or a modified translation rate for nitrate reductase mRNA, or it could have been due to interference with nitrate reduction, which could have limited reduced N metabolites to low levels. Further studies are needed to examine these possibilities.
