PpERF3b, a transcriptional repressor from peach, contributes to disease susceptibility and side branching in EAR-dependent and -independent fashions.
Article in Plant cell reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
key messagePeach ERF3b is a potent transcriptional repressor for defense-related genes even in the presence of similar levels of transcriptional activators and can interfere with plant development through pathways independent of the EAR motif. Ethylene response factors (ERFs) are a major group of plant transcription factors with either activation or repression capabilities on gene transcription. Repressor-type ERFs are characterised by an intrinsic motif, namely the ERF-associated amphiphilic repression motif (EAR). Here we report the identification of three genes from peach (Prunus persica), PpERF12, PpERF3a and PpERF3b, encoding for ERF repressors. The transcription kinetics of these genes was investigated by qRT-PCR after inoculation of peach leaves with Xanthomonas campestris pv. pruni. All three genes showed higher induction in the susceptible 'BabyGold 5', than in the resistant 'Venture' peach varieties suggesting a negative role for these genes in disease resistance. The functional potency of PpERF3b has been confirmed in vivo by its ability to repress the expression of GUS-reporter gene. To better understand the functional role of PpERF3b, the full-length and the EAR-truncated (PpERF3b∆EAR) genes were overexpressed in tobacco (Nicotiana tabacum). Both transgenic plants (PpERF3b and PpERF3b∆EAR) uniformly exhibited precocious side branching, which suggests the interference of PpERF3b with auxin-mediated dormancy of lateral shoots. Consistent with that the expression of auxin-response factors (Nt-ARF1, Nt-ARF6 and Nt-ARF8) was significantly downregulated in transgenic plants compared to the wild type (WT). Although side branching was independent of EAR motif, the response of transgenic plants to inoculation by Pseudomonas syringae pv. tabaci was EAR dependent. Transgenic plants overexpressing PpERF3b∆EAR showed less disease symptoms than those overexpressing the full-length gene or WT plants. Resistance of PpERF3b∆EAR plants was associated with enhanced induction of pathogenesis-related (PR) genes. Our results indicate that repressor-type ERFs might act through pathways that are dependent or independent of the EAR motif.
