Expression of NoLDSP in N. oceanica. Expression profiling of the NoLDSP-encoding gene determined by RT-qPCR and normalized against NoACTIN reference gene (A) and NoLDSP protein levels (B) under N deprivation and after NR. Each data point represents the average of three biological replicates. Values represent the means ± sd (n = 3). C, Representative image of cellular distribution of the NoLDSP:GFP construct during N deprivation.
