Pattern-triggered immunity is the first line of defense against infection by pathogens such as bacteria and fungi in plants, and this mechanism remains poorly defined in plant viruses. Double-stranded RNA (dsRNA) is an intermediate in the replication of plant RNA viruses, and is considered to be a conserved structure of plant viruses similar to pathogen-associated molecular pattern. Whether dsRNA is the elicitor that activates plant immunity in response to virus infection remains obscure. In this method, we use the cDNA of turnip mosaic virus genome as the template to in vitro synthesis of viral dsRNA and examine whether viral dsRNA could activate plant immunity in Arabidopsis thaliana, including MAPK kinase cascade and reactive oxygen burst. In order to provide some references for researchers studying dsRNA in terms of research methodology and experimental methods, we use western blot to measure MAPK kinase cascade and luminol-based assay to measure ROS burst in Arabidopsis thaliana treated by viral dsRNA.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 January 2024.
All research outputs
#17,190,674
of 25,252,667 outputs
Outputs from Methods in molecular biology
#5,967
of 14,149 outputs
Outputs of similar age
#131,565
of 253,838 outputs
Outputs of similar age from Methods in molecular biology
#101
of 238 outputs
Altmetric has tracked 25,252,667 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 14,149 research outputs from this source. They receive a mean Attention Score of 3.5. This one is in the 42nd percentile – i.e., 42% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 253,838 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 238 others from the same source and published within six weeks on either side of this one. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
