1 · What the graph read from 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.

2 · The registry

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

Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial pathogens using overexpression (OE) and short tandem target mimic (STTM) poplar lines of miR1447. Moreover, we demonstrated that PopTCTP contributed to poplar immunity as a target of miR1447 through integrative analysis of overexpression and RNAi lines, degradomes, transient co-expression assay and GFP fluorescence report system, and found that PopTCTP interacted with dnaJ A6. Further molecular and genetic analyses revealed that the promoters of miR1447 and PopTCTP were responsive to exogenous salicylic acid (SA) treatment. We showed that the negative regulatory role of miR1447 in SA signalling and poplar resistance was weakened with exogenous SA treatment. Notably, the miR1447-PopTCTP module contributed to PTI in poplar triggered by flg22 and associated with crosstalk between PTI and ETI via regulating MAPK signalling and scavenging ROS. Taken together, these findings unveil a novel pathway by which the miR1447-PopTCTP-SA signalling mediates disease resistance to diverse pathogens in poplar, offering promising genetic targets for tree breeding of disease resistance.
