Abstract

Pear ring rot, caused by Botryosphaeria species, is responsible for substantial economic losses by causing severe recession of pear tree growth in China. Mycovirus-mediated hypovirulence in plant pathogenic fungi is a crucial biological method to control fungal diseases. We conducted a large-scale and comprehensive transcriptome analysis to identify mRNA in B. dothidea in response to mycovirus. De novo sequencing technology from four constructed libraries of LW-C (Botryosphaeria dothidea chrysovirus 1, BdCV1), LW-P (Botryosphaeria dothidea partitivirus 1, BdPV1), LW-CP (LW-1 strain infection with BdCV1 and BdPV1), and Mock (free virus) was used to investigate and compare gene expression changes in B.dothidea strains infected with mycovirus. In total, 30,058 Unigenes with an average length of 2128 bp were obtained from 4 libraries of B. dothidea strains. These were annotated to specify their classified function. We demonstrate that mRNAs of B. dothidea strains in response to mycovirus are differentially expressed. In total, 5598 genes were up-regulated and 3298 were down-regulated in the LW-CP group, 4468 were up-regulated and 4291 down-regulated in the LW-C group, and 2590 were up-regulated and 2325 down-regulated in the LW-P group. RT-qPCR was used to validate the expression of 9 selected genes. The B. dothidea transcriptome was more affected by BdCV1 infection than BdPV1. We conducted GO enrichment analysis to characterize gene functions regulated by B. dothidea with mycovirus infection. These involved metabolic process, cellular process, catalytic activity, transporter activity, signaling, and other biological pathways. KEGG function analysis demonstrated that the enriched differentially expressed genes are involved in metabolism, transcription, signal transduction, and ABC transport. mRNA is therefore involved in the interaction between fungi and mycovirus. In addition, changes in differential accumulation levels of cp and RdRp of BdCV1 and BdPV1 in B. dothidea strains were evaluated, revealing that the accumulation of BdCV1 and BdPV1 is related to the phenotype and virulence of B. dothidea strain LW-1. The identification and analysis of mRNAs from B. dothidea was first reported at the transcriptome level. Our analysis provides further insight into the interaction of B. dothidea strains infection with chrysovirus 1 (BdCV1) and partitivirus 1 (BdPV1) at the transcriptome level.

Attention Score in Context

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 15 August 2018.
All research outputs
#10,205,111
of 13,376,849 outputs
Outputs from Virology Journal
#1,559
of 2,181 outputs
Outputs of similar age
#184,197
of 266,755 outputs
Outputs of similar age from Virology Journal
#1
of 1 outputs
Altmetric has tracked 13,376,849 research outputs across all sources so far. This one is in the 20th percentile – i.e., 20% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,181 research outputs from this source. They receive a mean Attention Score of 3.5. This one is in the 21st percentile – i.e., 21% 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 266,755 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
