Abstract
Brassica yellows virus (BrYV) is an economically important virus on cruciferous species. In this study, a one-pot reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay coupled with the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a system was developed for the detection of BrYV. The limit of detection of this method reached 32.8 copies of the BrYV ORF5, which is 100-fold more sensitive than the RT-LAMP method. Moreover, there was no cross-reactivity with other rapeseed-infecting RNA viruses or poleroviruses. We dried the CRISPR/Cas12a reagent in a trehalose and pullulan mixture to retain its efficacy at the RT-LAMP temperature of 63°C in order to allow portable BrYV detection in a water bath. The entire process can be performed in about 1 h, and a positive result can be rapidly and conveniently detected using a handheld UV lamp. In the field, the RT-LAMP-CRISPR/Cas12a assay was accurate and had higher sensitivity than RT-LAMP and reverse transcription-polymerase chain reaction assays. The novel RT-LAMP-CRISPR/Cas12a assay allows convenient, portable, rapid, low-cost, highly sensitive, and specific detection of BrYV and has great potential for on-site monitoring of BrYV.

Abstract
DNA methylation regulates gene expression under abiotic and biotic stresses. Recently, Gui et al. discovered that geminiviruses subverted DNA methylation-mediated defense through boosting the active DNA demethylation mediated by host DNA glycosylases to promote viral virulence. Their findings reveal a distinctive counter-defense strategy exploited by invading pathogens to achieve successful infection.

Abstract
Mixed virus infection has increasingly become a problem in the production of Solanaceae crops in recent years; therefore, a fast and accurate detection method is needed. In this study, a novel triplex immunostrip assay was developed for the simultaneous detection of tobacco mosaic virus (TMV), tobacco vein banding mosaic virus (TVBMV), and potato virus Y (PVY). The limits of detection of this novel immunostrip reached 200 ppb (ng/ml), 1 ppm (µg/ml), and 2 ppm for TMV, PVY, and TVBMV particles, respectively. Importantly, no cross-reactivity was observed among TMV, TVBMV, and PVY or to a nontarget virus. When the assay was applied to suspected virus-infected tobacco, tomato, and potato samples collected from fields in Southwest China, samples of single or mixed virus infection were successfully identified. In conclusion, the triplex immunostrip assay provides a fast and easy to use on-site detection method for field epidemiological studies of TMV, TVBMV, and PVY, and for managing diseases that are caused by them.

Abstract
Interferons (IFNs) are divided into 3 types (type I, type II, and type III) on the basis of sequence homology and functional properties. Recombinant IFNs have been approved by regulatory agencies in many countries for clinical treatment of hepatitis B, hepatitis C, and other diseases; these IFNs are mainly produced in microorganisms and mammalian cell systems. However, there are serious obstacles to the production of recombinant IFNs in microorganism systems; for example, the recombinant IFN may have different glycosylation patterns from the native protein, be present in insoluble inclusion bodies, be contaminated with impurities such as endotoxins and nucleic acids, have a short half-life in human blood, and incur high production costs. Some medicinal proteins have been successfully expressed in plants and used in clinical applications, suggesting that plants may also be a good system for IFN expression. However, there are still many technical problems that need to be addressed before the clinical application of plant-expressed IFNs, such as increasing the amount of recombinant protein expression and ensuring that the IFN is modified with the correct type of glycosylation. In this article, we review the classification of IFNs, their roles in antiviral signal transduction pathways, their clinical applications, and their expression in plant systems.

Abstract
Potato virus Y (PVY) causes huge damage to potato and tobacco production worldwide. The complete genome sequence of GZ, a PVY isolate (strain SYR-I) from Guizhou province, China, was cloned into the binary vector pCambia0390. Three introns were individually inserted into the P3 and CI ORFs to produce plasmid pCamPVY-GZ. The plasmid could infect plants of Nicotiana benthamiana, N. tabacum via agroinfiltration and plants of pepper and potato by mechanical inoculation. The green fluorescence protein gene of Aequoria victoriae was cloned into the encoding regions between nuclear inclusion body 'b' and coat protein genes in pCamPVY-GZ to produce pCamPVY-GZ-GFP, which could infect plants of N. benthamiana, N. tabacum, potato and tomato, and produce green fluorescence in the systemic leaves of inoculated plants. Mutations were introduced to pCamPVY-GZ to make the lysine (K) 391 and glutamic acid (E)410 of helper component-proteinase to arginine (R) and asparagic acid (E), respectively. Unlike wild type PVY-GZ, the mutant PVY-K391R/E410D could not induce veinal necrosis in N. tabacum plants. With an interval of 14 days, mutant PVY-K391R/E410D could protect N. tabacum plants from the infection of severe PVY strain. The results presented here provide a promising alternate for the prevention of diseases caused by PVY.

Abstract
Potato virus Y (PVY) is a globally and economically important pathogen of potato, tobacco, tomato and other staple crops and caused significant yield losses and reductions in quality.To explore the molecular PVY-host interactions, we analysed changes in the miRNA and mRNA profiles of tobacco in response to PVY infection. A total of 81 differentially expressed miRNAs belonging to 29 families and 8133 mRNAs were identified. The Gene Ontology (GO) enrichment analyses showed that genes encoding the DNA/RNA binding, catalytic activity and signalling molecules were all significantly enriched. Moreover, 88 miRNA-mRNA interaction pairs were identified through a combined analysis of the two datasets. We also found evidence showing that the virus-derived siRNAs (vsiRNAs) from the PVY genome target tobacco translationally controlled tumor protein (NtTCTP) mRNA and mediate plant resistance to PVY. Together, our findings revealed that both miRNA and mRNA expression patterns can be changed in response to PVY infection and novel vsiRNA-plant interactions that may regulate plant resistance to PVY. Both provide fresh insights into the virus-plant interactions.

Abstract
Maize rough dwarf disease caused by Rice black-streaked dwarf virus (RBSDV) is a major viral disease in China. It has been suggested that the viral infection of plants might cause distinct disease symptoms through the inhibition or activation of host gene transcription. We scanned the gene expression profile of RBSDV-infected maize through oligomer-based microarrays to reveal possible expression changes associated with symptom development. Our results demonstrate that various resistance-related maize genes and cell wall- and development-related genes, such as those for cellulose synthesis, are among the genes whose expression is dramatically altered. These results could aid in research into new strategies to protect cereal crops against viruses, and reveal the molecular mechanisms of development of specific symptoms in rough dwarf-related diseases.
