Identification and profiling of microRNAs in the midgut of Laodelphax striatellus after rice black-streaked dwarf virus (RBSDV) infection

ABSTRACT: MicroRNAs (miRNAs) are endogenous small noncoding RNAs (18–25 nt) that are involved in many physiological processes including development, cancer, immunity, apoptosis and host-microbe interactions through posttranscriptional regulation of gene expression. In this study, we measured the profile of small RNAs in the midgut of Laodelphax striatellus after rice black-streaked dwarf virus (RBSDV) infection. We identified 19 insect miRNAs that were differentially expressed compared with the RBSDV-free (VF) control. Among them, seven were upregulated and 12 downregulated in the RB midgut. Four miRNAs exhibited high expression levels (>500 reads) in either the VF or RBSDV-infected (RB) midgut; among them, three were up-regulated. This study identified critical miRNAs involved in the RBSDV infection in the midgut of L. striatellus.

Whole transcriptome analysis of coding and non-coding RNAs associated with RBSDV infection in Laodelphax striatellus (Fallén) midgut

Project description:We report the application of whole transcriptome sequencing technology for high-throughput profiling of coding and non-coding RNAs associated with RBSDV infection in Laodelphax striatellus (Fallén) midgut. Over 20 and 21 million clean reads from virus free (VF) and RBSDV infected (RB) libraries were obtained, respectively. Q30 base percentages of each sequencing sample were no less than 93.89%. More than 50.37% of the clean reads were perfectly mapped to the L. striatellus genome. The uniquely mapping ratio was ranged from 48.03% to 52.08%. A total of 35,316 mRNAs and 13,927 novel lncRNAs were identified from VF and RB libraries. 169 mRNAs and 176 lncRNAs were differentially expressed during RBSDV infection. RNA-seq data had a linear relationship with qRT–PCR results. Our study represents the first detailed transcriptomes analysis of L. striatellus midgut during RBSDV infection, with biologic replicates, generated by RNA-seq technology. Our data contribute to the understanding of the function of coding and non-coding RNAs in the regulation of viral infection.

iTRAQ-based quantitative proteomics suggests mitophagy involvement after Rice black-streaked dwarf virus acquisition in insect vector small brown planthopper Laodelphax striatellus Fallén

Project description:Plant virus triggers numerous responses in its insect vectors. Using the iTRAQ-based quantitative proteomics analysis. Early responses of the insect vector small brown planthopper (Laodelphax striatellus Fallén, SBPH) after acquiring Rice black-streaked dwarf virus (RBSDV) at 3 days and 5 days post first access to disease plants (padp), respectively, were revealed. A total of 582 differentially abundant proteins (DAPs) in SBPH with a fold change > 1.500 or <0.667 (p-value<0.05) were identified. The proteomic analysis in SBPH at 3 days padp revealed 106 high abundant proteins and 193 low abundant proteins, while 5 days padp revealed 214 high abundant proteins and 182 low abundant proteins. Among them, 51 high abundant proteins and 42 low abundant proteins were consistently differentially abundant at both 3 days and 5 days padp.

Differentially expressed miRNAs between the ovaries of Wolbachia-infected and Wolbachia-uninfected Laodelphax striatellus

Project description:Laodelphax striatellus is naturally infected with the Wolbachia strain wStri, which significantly increase the fecundity of its host. Wolbachia-infected females produce 30%–40% more eggs than Wolbachia-uninfected females. MicroRNAs (miRNAs) are a class of endogenous non-coding small RNAs that play critical roles in the regulation of gene expression at post-transcriptional level. Here we report the differentially expressed miRNAs between Wolbachia-infected and Wolbachia-uninfected strains of L. striatellus ovaries. Our data may be helpful to explore the molecular mechanisms by which Wolbachia increase the fecundity of Laodelphax striatellus.

Transcriptome analysis of rice reveals the lncRNA-mRNA regulatory network in response to Rice black-streaked dwarf virus infection

Project description:To better understand the response mechanism of rice plants to Rice black-streaked dwarf virus (RBSDV) infection, we performed a comparative transcriptome analysis between the RBSDV-infected and non-infected rice plants. A total of 1342 mRNAs and 22 lncRNAs were identified to be differentially expressed after RBSDV infection. Most differentially expressed transcripts involved in the plant-pathogen interaction pathway were upregulated after RBSDV infection, indicating the activation of rice defense response by RBSDV. A network of differentially expressed lncRNAs (DElncRNAs) and mRNAs (DEmRNAs) was then constructed. In this network, there are 56 plant-pathogen interaction-related DEmRNAs co-expressing with 20 DElncRNAs, suggesting these DElncRNAs and DEmRNAs may play essential roles in rice innate immunity against RBSDV.

Comparative proteomic analysis of maize (Zea may L.) seedlings under rice black-streaked dwarf virus infection

Project description:Maize rough dwarf disease (MRDD) is a severe disease that has been occurring frequently in southern China and many other Asian countries. MRDD is caused by the infection of Rice black streaked dwarf virus (RBSDV) and leads to significant economic losses in maize production. To well understand the destructive effects of RBSDV infection on maize growth, comparative proteomic analysis of maize seedlings under RBSDV infection was performed using an integrated approach involving LC-MS/MS and TMT labeling. Our study identified 7615 maize proteins, of which 6319 proteins were quantified. A total of 116 differentially expressed proteins (DEPs) were identified, including 35 up- and 81 down-regulated proteins under RBSDV infection. Enrichment analysis showed that the DEPs were most strongly associated with Cyanoamino acid metabolism, protein processing in ER, and ribosome-related pathways. Two sulfur metabolism-related proteins were significantly reduced, indicating that sulfur may participate in the resistance against RBSDV infection. Furthermore, 15 DEPs involved in six metabolic pathways were identified in maize under RBSDV infection. Our data revealed that the responses of maize to RBSDV infection were controlled by various metabolic pathways.
