Hong Kong
The former British crown colony located off the southeast coast of China, comprised of Hong Kong Island, Kowloon Peninsula, and New Territories. The three sites were ceded to the British by the Chinese respectively in 1841, 1860, and 1898. Hong Kong reverted to China in July 1997. The name represents the Cantonese pronunciation of the Chinese xianggang, fragrant port, from xiang, perfume and gang, port or harbor, with reference to its currents sweetened by fresh water from a river west of it.

Classification
Bacteria
One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

Functional specialization and evolution of leader proteinases in the family Closteroviridae. (1/17)
Members of the Closteroviridae and Potyviridae families of the plant positive-strand RNA viruses encode one or two papain-like leader proteinases. In addition to a C-terminal proteolytic domain, each of these proteinases possesses a nonproteolytic N-terminal domain. We compared functions of the several leader proteinases using a gene swapping approach. The leader proteinase (L-Pro) of Beet yellows virus (BYV; a closterovirus) was replaced with L1 or L2 proteinases of Citrus tristeza virus (CTV; another closterovirus), P-Pro proteinase of Lettuce infectious yellows virus (LIYV; a crinivirus), and HC-Pro proteinase of Tobacco etch virus (a potyvirus). Each foreign proteinase efficiently processed the chimeric BYV polyprotein in vitro. However, only L1 and P-Pro, not L2 and HC-Pro, were able to rescue the amplification of the chimeric BYV variants. The combined expression of L1 and L2 resulted in an increased RNA accumulation compared to that of the parental BYV. Remarkably, this L1-L2 chimera exhibited reduced invasiveness and inability to move from cell to cell. Similar analyses of the BYV hybrids, in which only the papain-like domain of L-Pro was replaced with those derived from L1, L2, P-Pro, and HC-Pro, also revealed functional specialization of these domains. In subcellular-localization experiments, distinct patterns were observed for the leader proteinases of BYV, CTV, and LIYV. Taken together, these results demonstrated that, in addition to a common proteolytic activity, the leader proteinases of closteroviruses possess specialized functions in virus RNA amplification, virus invasion, and cell-to-cell movement. The phylogenetic analysis suggested that functionally distinct L1 and L2 of CTV originated by a gene duplication event. (+info)Effects of modification of the transcription initiation site context on citrus tristeza virus subgenomic RNA synthesis. (2/17)
Citrus tristeza virus (CTV), a member of the Closteroviridae, has a positive-sense RNA genome of about 20 kb organized into 12 open reading frames (ORFs). The last 10 ORFs are expressed through 3'-coterminal subgenomic RNAs (sgRNAs) regulated in both amounts and timing. Additionally, relatively large amounts of complementary sgRNAs are produced. We have been unable to determine whether these sgRNAs are produced by internal promotion from the full-length template minus strand or by transcription from the minus-stranded sgRNAs. Understanding the regulation of 10 sgRNAs is a conceptual challenge. In analyzing commonalities of a replicase complex in producing so many sgRNAs, we examined initiating nucleotides of the sgRNAs. We mapped the 5' termini of intermediate- (CP and p13) and low- (p18) produced sgRNAs that, like the two highly abundant sgRNAs (p20 and p23) previously mapped, all initiate with an adenylate. We then examined modifications of the initiation site, which has been shown to be useful in defining mechanisms of sgRNA synthesis. Surprisingly, mutation of the initiating nucleotide of the CTV sgRNAs did not prevent sgRNA accumulation. Based on our results, the CTV replication complex appears to initiate sgRNA synthesis with purines, preferably with adenylates, and is able to initiate synthesis using a nucleotide a few positions 5' or 3' of the native initiation nucleotide. Furthermore, the context of the initiation site appears to be a regulatory mechanism for levels of sgRNA production. These data do not support either of the established mechanisms for synthesis of sgRNAs, suggesting that CTV sgRNA production utilizes a different mechanism. (+info)Complete nucleotide sequence and genome organization of Grapevine leafroll-associated virus 3, type member of the genus Ampelovirus. (3/17)
This study reports on the complete genome sequence of Grapevine leafroll-associated virus 3, the type member of the genus Ampelovirus. The genome is 17 919 nt in size and contains 13 open reading frames (ORFs). Previously, the sequence of 13 154 nt of the 3'-terminal of the genome was reported. The newly sequenced portion contains a 158 nt 5' UTR, a single papain-like protease and a methyltransferase-like (MT) domain. ORF1a encodes a large polypeptide with a molecular mass of 245 kDa. With a predicted +1 frameshift, the large fusion protein generated from ORF1a/1b would produce a 306 kDa polypeptide. Phylogenetic analysis using MT domains further supports the creation of the genus Ampelovirus for mealy-bug-transmitted viruses in the family Closteroviridae. (+info)Genetic variability and population structure of Grapevine leafroll-associated virus 3 isolates. (4/17)
The genetic variability and population structure of a collection of 45 Grapevine leafroll-associated virus 3 (GLRaV-3) isolates were studied by single-stranded conformation polymorphism (SSCP) and sequence analysis of the RNA-dependent RNA polymerase (RdRp), heat-shock protein 70 homologue (HSP-70) and coat protein (CP) genes. The distribution of SSCP profiles was not correlated with the geographical origin of the isolates, indicating that GLRaV-3 is a single, undifferentiated population. The majority of the isolates showed an SSCP profile and a population structure that were composed of a single predominant variant. However, 10% of the isolates for the RdRp and HSP-70 genes and 15% for the CP gene were composed of a combination of two or more variants. Estimation of genetic diversity and phylogenetic analysis disclosed the possible existence of vines with mixed infections by diverging sequence variants, showing, in some cases, possible recombination events. Furthermore, differences in the genetic diversity and constraints existing in the three regions analysed indicated a higher variability in the CP gene. The epidemiological and biological implications of this finding are discussed. (+info)Transmission of grapevine leafroll-associated virus 3 by the vine mealybug (Planococcus ficus). (5/17)

Retrovirus
When retroviruses have integrated their own genome into the germ line, their genome is passed on to a following generation. These endogenous retroviruses (ERVs), contrasted with exogenous ones, now make up 5-8% of the human genome.[7] Most insertions have no known function and are often referred to as "junk DNA". However, many endogenous retroviruses play important roles in host biology, such as control of gene transcription, cell fusion during placental development in the course of the germination of an embryo, and resistance to exogenous retroviral infection. Endogenous retroviruses have also received special attention in the research of immunology-related pathologies, such as autoimmune diseases like multiple sclerosis, although endogenous retroviruses have not yet been proven to play any causal role in this class of disease.[8] While transcription was classically thought to occur only from DNA to RNA, reverse transcriptase transcribes RNA into DNA. The term "retro" in retrovirus refers to ...
Hepadnaviridae
The hepatitis envelope proteins are composed of subunits made from the viral preS1, preS2, and S genes. The L (for "large") envelope protein contains all three subunits. The M (for "medium") protein contains only preS2 and S. The S (for "small") protein contains only S. The genome portions encoding these envelope protein subuntis share both the same frame and the same stop codon (generating nested transcripts on a single open reading frame. The pre-S1 is encoded first (closest to the 5' end), followed directly by the pre-S2 and the S. When a transcript is made from the beginning of the pre-S1 region, all three genes are included in the transcript and the L protein is produced. When the transcript starts after the pro-S1 at the beginning of the pre-S2 the final protein contains the pre-S2 and S subunits only and therefore is an M protein. The smallest envelope protein containing just the S subunit is made most because it is encoded closest to the 3' end and comes from the shortest transcript. ...
Betanodavirus
Viruses in Betanodavirus are non-enveloped, with icosahedral geometries, and T=3 symmetry. The diameter is around 30 nm. Genomes are linear and segmented, bipartite, around 21.4kb in length.[8]. The crystal structure of a betanodavirus- T=3 Grouper nervous necrosis virus (GNNV)-like particle has been determined by X-ray crystallography. The virus-like particle contains 180 subunits of the capsid protein, and each capsid protein (CP) shows three major domains: (i) the N-terminal arm, an inter-subunit extension at the inner surface; (ii) the shell domain (S-domain), a jelly-roll structure; and (iii) the protrusion domain (P-domain) formed by three-fold trimeric protrusions. [10]. ...
Polydnavirus
Nucleic acid analysis suggests a very long association of the viruses with the wasps (greater than 70 million years).. Two proposals have been advanced for how the wasp/virus association developed. The first suggests that the virus is derived from wasp genes. Many parasitoids that do not use PDVs inject proteins that provide many of the same functions, that is, a suppression of the immune response to the parasite egg. In this model, the braconid and ichneumonid wasps packaged genes for these functions into the viruses-essentially creating a gene-transfer system that results in the caterpillar producing the immune-suppressing factors. In this scenario, the PDV structural proteins (capsids) were probably "borrowed" from existing viruses.. The alternative proposal suggests that ancestral wasps developed a beneficial association with an existing virus that eventually led to the integration of the virus into the wasp's genome. Following integration, the genes responsible for virus replication and the ...
Virus
Louis Pasteur was unable to find a causative agent for rabies and speculated about a pathogen too small to be detected using a microscope.[21] In 1884, the French microbiologist Charles Chamberland invented a filter (known today as the Chamberland filter or the Pasteur-Chamberland filter) with pores smaller than bacteria. Thus, he could pass a solution containing bacteria through the filter and completely remove them from the solution.[22] In 1892, the Russian biologist Dmitri Ivanovsky used this filter to study what is now known as the tobacco mosaic virus. His experiments showed that crushed leaf extracts from infected tobacco plants remain infectious after filtration. Ivanovsky suggested the infection might be caused by a toxin produced by bacteria, but did not pursue the idea.[23] At the time it was thought that all infectious agents could be retained by filters and grown on a nutrient medium - this was part of the germ theory of disease.[2] In 1898, the Dutch microbiologist Martinus ...
Herpesvirales
The Herpesvirales naming system originated in 1973 and has been elaborated considerably since. All herpesviruses described since this system was adopted have been named in accordance with it. The recommended naming system specifies that each species name consists of three parts: a first word, a second word, and finally a number. The first word should be derived from the taxon (family or subfamily) to which its primary natural host belongs. The subfamily name is used for viruses from members of the family Bovidae or from primates (the virus name ending in -ine, e.g. bovine), and the host family name for other viruses (ending in -id, e.g. equid). Human herpesviruses have been treated as an exception (human rather than hominid). Following the host-derived term, species in the family Herpesviridae, which are divided into subfamilies Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae, will have the word alphaherpesvirus, betaherpesvirus, or gammaherpesvirus added, respectively. Species in ...
History of virology
Despite his other successes, Louis Pasteur (1822-1895) was unable to find a causative agent for rabies and speculated about a pathogen too small to be detected using a microscope.[1] In 1884, the French microbiologist Charles Chamberland (1851-1931) invented a filter - known today as the Chamberland filter - that had pores smaller than bacteria. Thus, he could pass a solution containing bacteria through the filter and completely remove them from the solution.[2] In 1876, Adolf Mayer, who directed the Agricultural Experimental Station in Wageningen was the first to show that what he called "Tobacco Mosaic Disease" was infectious, he thought that it was caused by either a toxin or a very small bacterium. Later, in 1892, the Russian biologist Dmitry Ivanovsky (1864-1920) used a Chamberland filter to study what is now known as the tobacco mosaic virus. His experiments showed that crushed leaf extracts from infected tobacco plants remain infectious after filtration. Ivanovsky suggested the infection ...
Gammaherpesvirinae
Gammaherpesviruses are of primary interest due to the two human viruses, EBV and KSHV and the diseases they cause. The gammaherpesviruses replicate and persist in lymphoid cells but some are capable of undergoing lytic replication in epithelial or fibroblast cells. Gammaherpesviruses may be a cause of chronic fibrotic lung diseases in humans and in animals.[10] Murid herpesvirus 68 is an important model system for the study of gammaherpesviruses with tractable genetics. The gammaherpesviruses, including HVS, EBV, KSHV, and RRV, are capable of establishing latent infection in lymphocytes.[9] Attenuated virus mutants represent a promising approach towards gamma-herpesvirus infection control. Surprisingly, latency-deficient and, therefore, apathogenic MHV-68 mutants are found to be highly effective vaccines against these viruses.[8] Research in this area is almost exclusively performed using MHV68 as KSHV and EBV (the major human pathogens of this family) do not productively infect model organisms ...
Birnaviridae
The Birnaviridae genome encodes several proteins: Birnaviridae RNA-directed RNA polymerase (VP1), which lacks the highly conserved Gly-Asp-Asp (GDD) sequence, a component of the proposed catalytic site of this enzyme family that exists in the conserved motif VI of the palm domain of other RNA-directed RNA polymerases.[3] The large RNA segment, segment A, of birnaviruses codes for a polyprotein (N-VP2-VP4-VP3-C) [4] that is processed into the major structural proteins of the virion: VP2, VP3 (a minor structural component of the virus), and into the putative protease VP4.[4] VP4 protein is involved in generating VP2 and VP3.[4] recombinant VP3 is more immunogenic than recombinant VP2.[5] Infectious pancreatic necrosis virus (IPNV), a birnavirus, is an important pathogen in fish farms. Analyses of viral proteins showed that VP2 is the major structural and immunogenic polypeptide of the virus.[6][7] All neutralizing monoclonal antibodies are specific to VP2 and bind to continuous or discontinuous ...

Members of the genus Closterovirus whose genomes have been sequenced show three types of genome organization exemplified by those of BYV (Figure 1.Closterovirus), CTV (Figure 2.Closterovirus) and beet yellow stunt virus (BYSV): (i) the BYV genome contains eight ORFs flanked by 5′- and 3′-UTRs of 107 and 181 nt, respectively; (ii) the genome of CTV has 12 ORFs and UTRs of 107 nt at the 5′-end and 275 nt at the 3′-end, and differs from the BYV genome in having two papain-like protease domains in the ORF1a-encoded protein, an extra 5′-proximal ORF (ORF2) encoding a 33 kDa product with no similarity to any other protein in databases, and two extra 3′-proximal ORFs (ORF9 and ORF11); and (iii) the genome of BYSV has 10 ORFs and a 3′-UTR of 241 nt, intermediate between that of the BYSV and CTV UTRs. A further difference with the BYSV genome rests in the presence of an extra ORF (ORF2) encoding a 30 kDa polypeptide with no similarity to any other protein in databases. This ORF is located ...
