Comparative analysis of differentially expressed genes (DEGs) in roots of twoBrassica oleraceaaccessions (C6 and F103) grown hydroponically for two weeks in solutions containing 0.025 mM P (Low P) and 0.25 mM P (High P). Differentially expressed genes were defined by comparing the gene expression in theLow Ptreatment with the gene expression in theHigh P治疗的每一个B. oleraceaaccession.a年代chematic representation of the common and accession-specific DEGs.bGene ontology analysis of enriched functional categories of these DEGs. Depicted arep-values to highlight the significance of the over-representation of the corresponding functional category. Only child terms are displayed here. The full analysis can be found in Additional file2: Table S6.cA MapMan analysis illustrating responses of functional pathways to theLow Ptreatment. The image was designed after the MapMan output for cellular overview. Line graphs below categories show expression of respective genes in response to decreasing P supply with the average and the confidence interval are shown in red.Arabidopsis thalianaorthologues ofB. oleraceaP-responsive DEGs were used as input together with expression values detected in the twoB. oleraceaaccessions
