Consisting of pools of five plants. Gene expression levels are relative to the internal manage -actin genes. JAZ3 and JAZ4 expression was not examined due to lack of F. oxysporum inducibility (Fig. 1).Fig. 10. Priming of JA-regulated gene expression in jaz7-1D. Extremely MeJA inducible genes in wild-type were typically not as inducible in jaz7-1D. Shown is often a subset of differentially regulated genes in the jaz7-1D mutant following a manage or MeJA (6 h) therapy as identified by microarray evaluation. Col-0 handle and MeJA: white and dark gray boxes, respectively. jaz7-1D manage and MeJA: light gray and black boxes, respectively. The numbers above MeJA columns represent fold-induction over control therapy. Values are averages E of 4 biological replicates consisting of pools of 20 plants.JAZ7 interacts with all the transcriptional activators MYC3 and MYC4, as well as the transcriptional repressor JAMTo dissect the potential mechanism of JAZ7 in JA-responses we tested for JAZ7 interactions using the transcriptional activators MYC2, MYC3 and MYC4 that may bind to most JAZ proteins (Chini et al., 2009; Cheng et al., 2011; Fernandez-Calvo et al., 2011; Niu et al., 2011). Utilizing Y2H approaches, numerous groups have reported JAZ7 binding to MYC2, MYC3 and MYC4, when other folks have not detected these interactions (Chini et al., 2009; Arabidopsis Interactome Mapping Consortium, 2011; Cheng et al., 2011; Fernandez-Calvo et al., 2011; Qi et al., 2011). To address this, we performed Y2H research applying JAZ5 and JAZ8 as positive controls; both interact with MYC2, MYC3 and MYC4 in all published studies to our knowledge (Cheng et al., 2011; Fernandez-Calvo et al., 2011). We identified a sturdy interaction amongst JAZ7-MYC3 and JAZ7-MYC4, but failed to determine a Eperisone web JAZ7-MYC2 interaction (Fig. 11C).To determine whether or not JAZ7 has the capacity to repress these transcriptional activators we performed transcriptional activation assays with JAZ7 against MYC3 and MYC4. In these experiments, we co-bombarded a reporter gene construct containing the GAL4 upstream activation sequence (pGAL4UAS) linked to the GUS gene (pGAL4UAS-GUS), together with CaMV35S expression constructs of MYC3 or MYC4 fused towards the GAL4 DNA binding domain (GAL4BD) or 4-Hydroxychalcone Epigenetics GAL4BD alone, also as empty vector, JAZ7, JAZ7mEAR or JAZ8 under CaMV35S promoter (Fig. 13). Additionally, an expression construct with the firefly luciferase (LUC) gene was co-bombarded as a normalization handle. The addition in the vector constructs expressing either MYC3- or MYC4-GAL4BD made drastically higher transcription activity with the GUS reporter gene in comparison to the handle effector plasmid (GAL4BD only) when co-bombarded with the empty vector. Even so, transcription activation abilities from the MYC3 and MYC4-GAL4BD fusionActivation-tagged jaz7-1D mutant confers susceptibility to Fusarium oxysporum |Table 1.
