Fig. 4From: Cloning and characterization of nitrate reductase gene in kelp Saccharina japonica (Laminariales, Phaeophyta)qPCR analysis of SjNR transcript level. A Evaluated SjNR transcript level under N deprivation. B Evaluated SjNR transcript levels to different N sources (NH4Cl or NaNO3). The SjNR transcript levels in two experiments were separately normalized by assuming that the highest level of SjNR transcript = 100%Back to article page
