Microarray analysis and scale-free gene networks identify candidate regulators in drought-stressed roots of loblolly pine (P. taeda L.)

Table 2 Network Topology Statistics

^aGlobal gene networks were generated via Weighted Gene Correlation Network Analysis (WGCNA) [37] and network properties were calculated using the Network Analyzer plugin [51] that was developed for Cytoscape [50].
^b Identifies networks that have a topology similar to other biological networks and ranges from 0 - 1 [37].
^cAverage shortest path length between two nodes.
^dMaximum distance amongst all distances calculated between two nodes.
^eAverage number of connections made by each node.
^fNetwork topology that resembles a star has a centralization of 1 and decentralized networks have a centralization of 0. Heterogeneity reflects the tendency of a network to contain hub nodes [119].
^gThe average clustering coefficient can be used to measure whether the network exhibits modular organization [120].
