HbWRKY40 plays an important role in the regulation of pathogen resistance in Hevea brasiliensis.
Article in Plant cell reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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 messageOverexpression of HbWRKY40 induces ROS burst in tobacco and increases disease resistance in Arabidopsis; RNA-seq and ChIP assays revealed the regulatory network of HbWRKY40 in plant defense. WRKY, a family of plant transcription factors, are involved in the regulation of numerous biological processes. In rubber tree Hevea brasiliensis, the roles of WRKYs remain poorly understood. In the present study, a total of 111 genes encoding putative HbWRKY proteins were identified in the H. brasiliensis genome. Among these genes, HbWRKY40 transcripts were significantly induced by Colletotrichum gloeosporioides and salicylic acid. To assess its roles in plant defense, HbWRKY40 was over-expressed in Nicotiana benthamiana and Arabidopsis thaliana. The results showed that HbWRKY40 significantly induced reactive oxygen species burst in N. benthamiana and increased resistance of Arabidopsis against Botrytis cinerea. Transient expression in mesophyll cell protoplasts of H. brasiliensis showed that HbWRKY40 localizes at nuclei. In addition, transcripts of 145 genes were significantly up-regulated and 6 genes were down-regulated in the protoplasts over-expressing HbWRKY40 based on the RNA-seq analysis. Among these potential downstream targets, 12 genes contain potential WRKY-binding sites at the promoter regions. Further analysis through chromatin immunoprecipitation revealed that 10 of these 12 genes were the downstream targets of HbWRKY40. Taken together, our findings indicate that HbWRKY40 plays an important role in the disease resistance by regulating defense-associated genes in H. brasiliensis.
