Gene regulation under P-starvation in Brassica oleracea var. alboglabra cv. A12DHd as a function of the gDNA hybridisation intensity threshold used to generate probe mask files for the transcriptome analysis. Total RNA samples were extracted from control B. oleracea shoots and from the shoots of plants grown in the absence of P for 100 h (n = 4). (a) genes significantly regulated under P starvation at Benjamini and Hochberg False Discovery Rate multiple test corrected (BH-FDR MTC) P < 0.05. (b) genes regulated > ± 1.3-fold under P starvation. (c) genes significantly regulated > ± 1.3-fold under P starvation (BH-FDR MTC P < 0.05). Data in 1.
