We identified 163 AP2/EREBP (APETALA2/ethylene-responsive element-binding protein) genes in rice. analyzed gene structures, phylogenies, domain duplication, genome localizations and expression profiles. Conserved amino acid residues phylogeny construction using the AP2/ERF conserved sequence suggest that rice OsAP2/EREBP family can be classified broadly into four subfamilies [AP2, RAV (related to ABI3/VP1), DREB (dehydration-responsive ERF (ethylene-responsive factor)]. The chromosomal of...
Sedoreoviridae is a large family of icosahedral viruses that are usually regarded as non-enveloped with segmented (10–12 linear segments) dsRNA genomes 18–26 kbp. Sedoreovirids have broad host range, infecting mammals, birds, crustaceans, arthropods, algae and plants. Some them important pathogenic potential for humans (e.g. rotavirus A), livestock bluetongue virus) plants rice dwarf virus).

Spinareoviridae is a large family of icosahedral viruses that are usually regarded as non-enveloped with segmented (9-12 linear segments) dsRNA genomes 23-29 kbp. Spinareovirids have broad host range, infecting animals, fungi and plants. Some important pathogenic potential for humans (e.g. Colorado tick fever virus), livestock avian orthoreoviruses), fish aquareoviruses) plants rice ragged stunt virus black streaked dwarf virus).

The family Phenuiviridae comprises viruses with 2-8 segments of negative-sense or ambisense RNA, comprising 8.1-25.1 kb in total. Virions are typically enveloped spherical pleomorphic morphology but can also be non-enveloped filaments. Phenuivirids infect animals including livestock and humans, birds, plants fungi, as well arthropods that serve single hosts act biological vectors for transmission to plants. include important pathogens livestock, seafood agricultural crops. This is a summary...
ABSTRACT Prior to 2017, the family Bunyaviridae included five genera of arthropod and rodent viruses with tri-segmented negative-sense RNA genomes related Bunyamwera virus. In International Committee on Taxonomy Viruses (ICTV) promoted order Bunyavirales subsequently greatly expanded its composition by adding multiple families for non-segmented polysegmented animals, fungi, plants, protists. The continued accelerated discovery bunyavirals highlighted that an would not suffice depict...
Rice stripe disease, caused by rice virus (RSV), is one of the major diseases in east Asia. plants infected with RSV usually show symptoms such as chlorosis, weakness, necrosis newly emerged leaves and stunting. To reveal cellular systems influenced infection, temporal changes transcriptome RSV-infected were monitored a customized oligoarray system. The indicated that protein-synthesis machineries energy production mitochondrion activated whereas chloroplast synthesis cell-structure...
Rice stripe virus (RSV) has a serious negative effect on rice production in temperate regions of East Asia. Focusing the putative importance selection target sequences for RNA interference (RNAi), we analysed effects potential each coding genes RSV genome, using transgenic plants that expressed set inverted-repeat (IR) constructs. The reactions inoculated T(1) to were divided subjectively into three classes, namely highly resistant, moderately resistant and lacking enhanced resistance RSV,...
The P9-1 protein of Rice black streaked dwarf virus accumulates in viroplasm inclusions, which are structures that appear to play an important role viral morphogenesis and commonly found viruses the family Reoviridae. Crystallographic analysis revealed structural features allow form dimers via hydrophobic interactions. Each dimer has carboxy-terminal regions, resembling arms, extend neighboring dimers, thereby uniting sets four lateral interactions, yield cylindrical octamers. importance...
Background Rice dwarf virus (RDV) is the causal agent of rice disease, which often results in severe yield losses East Asian countries. The disease symptoms are stunted growth, chlorotic specks on leaves, and delayed incomplete panicle exsertion. Three RDV strains, O, D84, S, were reported. RDV-S causes most symptoms, whereas RDV-O mildest. Twenty amino acid substitutions found 10 12 proteins among three strains. Methodology/Principal Findings We analyzed gene expression response to...
Expression levels of the NAC gene family were studied in rice infected with Rice dwarf virus (RDV), black-streaked (RBSDV), grassy stunt (RGSV), ragged (RRSV) and transitory yellowing (RTYV). Microarray analysis showed that 75 (68%) OsNAC genes differentially regulated during infection RDV, RBSDV, RGSV, RRSV compared control. The number upregulated was highest RGSV infection, while lowest found RTYV infection. These phenomena correlate severity syndromes induced by infections. Most subgroups...
Abstract An increasing number of plant viruses and viroids have been reported from all over the world due largely to metavirogenomics approaches with technological innovation. Herein, official changes virus taxonomy, including establishment megataxonomy amendments codes classification nomenclature, recently made by International Committee on Taxonomy Viruses were summarized. The continued efforts virology community Japan index occurring in Japan, which represent 407 viruses, 303 species 104...
Rice grassy stunt virus (RGSV), a member of the genus Tenuivirus, causes significant economic losses in rice production South, Southeast, and East Asian countries. Growing resistant varieties is most efficient method to control RGSV; however, suitable resistance genes have not yet been found natural resources. One promising methods confer against RGSV use RNA interference (RNAi). It important target viral that play roles infection proliferation at an early stage replication. Our recent...
Broad-spectrum disease resistance against two or more types of pathogen species is desirable for crop improvement. In rice, Xanthomonas oryzae pv. (Xoo), the causal bacteria rice leaf blight, and Magnaporthe oryzae, fungal causing blast, are most devastating pathogens. We identified BROAD-SPECTRUM RESISTANCE 1 (BSR1) gene a BIK1-like receptor-like cytoplasmic kinase using FOX hunting system, demonstrated that BSR1-overexpressing (OX) showed strong to bacterial pathogen, Xoo M. oryzae. Here,...
Thioredoxin (TRX) is a multi-functional redox protein. Genome-wide survey and expression profiles of different stresses were observed. Conserved amino acid residues phylogeny construction using the OsTRX conserved domain sequence suggest that TRX gene family can be classified broadly into six subfamilies in rice. We compared potential birth-and-death events genes. The Ka/Ks ratio measure to explore mechanism 3 evolutionary stages genes divergence after duplication. used 270 from monocots...
The Ophioviridae is a family of filamentous plant viruses, with single-stranded negative, and possibly ambisense, RNA genomes 11.3-12.5 kb divided into 3-4 segments, each encapsidated separately. Virions are naked nucleocapsids, forming kinked circles at least two different contour lengths. sole genus, Ophiovirus, includes seven species. Four ophioviruses soil-transmitted their natural hosts include trees, shrubs, vegetables bulbous or corm-forming ornamentals, both monocots dicots. This...
