Metabolism was obtained. The strategy applied here will probably be valuable to direct further studies by reverse genetic methods and eventually decipher the mechanisms by which root epidermal cells are re-programmed to adapt to Pi deficiency.correlation threshold of 0.7. The generated co-expression networks had been visualized by Cytoscape (http://www. cytoscape.org). If a single cluster of genes didn’t have any connection (with out any edges) to any other cluster inside the co-expression network, we referred to such a cluster as a module.Construction of root hair-specific networks of Pi-responsive PK and PP genesMethodsData collection and processingTranscriptome information of roots from plants grown in the presence or absence of Pi from 13-d-old Arabidopsis seedlings by RNA-seq were downloaded from a public database (NCBI: SRA050356.1) and analyzed as described in [22]. Microarray information of 2,671 ATH1 arrays in the NASCarray database (http://affymetrix.arabidopsis.info/) had been downloaded and normalized using the RMA function with the Affy package of the Bioconductor software. Amongst the 2,671 arrays, 300 root-related arrays were manually identified as described in [9]. PK and PP genes were retrieved on the basis of TAIR ten release of Arabidopsis genome.Generation of co-expression networks and modules of Pi-responsive PK and PP genes utilizing the MACCU toolboxTo receive a root hair cell-specific network of Pi-responsive PK and PP genes, the 208 root epidermal `core’ genes had been very first mined from the datasheet described in [45]. Subsequent, Pi-responsive PK and PP genes involved in the module of pollen tube/root hair improvement and growth have been extracted (bait genes), combined together with the genes from the root epidermal `core’ (preys), and made use of for producing co-expression network using the MACCU toolbox having a Pearson correlation threshold of 0.7. The resulting networks shows only these nodes (genes) and edges (relationships between genes) that had been linked by no less than one edge should with bait. Edges linked to two preys have been excluded.Extra filesAdditional file 1: Expression of 1,118 kinase genes in Arabidopsis retrieved from TAIR10 roots.
