Gene co-expression networks and module assignment for a combined flag leaf development [34], and current RNA-Seq datasets. a 23 modules were detected between 17,637 genes (nodes). The top half of the network (yellow circle) consists of genes primarily expressed in flag leaves (early development on the right, senescence onset on the left) white arrow. Bottom white circle of the network consists of genes primarily expressed in seedlings used in the current study (GB-induced host genes in the lower-left; magenta circle). Module 2 (M2, orange dots) contained the network of co-expressed genes associated with GB infestation. Module 7, (M7, yellow dots) contained genes co-expressed in GB-infested plants and during senescence of flag leaves. Module 18 (M18, green dots) consisted of genes co-expressed in expanding flag leaves and during the latter stages of GB-infestation. Module profiles within this network are shown in supporting Additional file 6: Figure S2. b SAGs associated with different modules; dots color coded as in Panel a. c WRKY transcription factors; dots color coded as in Panel a. d MYB transcription factors; dots color coded as in Panel a. Gene abbreviations, identities, and normalized transcript counts are provided in Additional file 4: Data S2
