Satellite RNAs Cucumber mosaic virus (an epiphytotic of lethal necrotic disease among tomato plants in France in 1972). This was unusual because of the severity and atypical nature of the symptoms associated with infections of tomato plants (See description of cucumber mosaic in prior text). Enhanced response of tomatoes to this disease were associated with host used for virus propagation; virus grown in tobacco or tomato yielded an enhanced necrotic response, those propagated in cucurbit hosts yielded a reduce necrotic response. RNA extractions of necrotic tomato plants revealed the presence of variable amounts of a small RNA species in addition to the expected three genomic and one subgenomic RNAs. This 5th RNA species was designated CARNA 5 (i.e., CMV-associated RNA 5 or CMV satRNA), a satellite RNA. When CARNA 5 is present with CMV, symptoms of the disease are enhanced in tomato plants, while in tabasco pepper the presence of CARNA 5 tends to attenuate the disease symptoms caused by CMV. ...

To investigate the extent of the 3 end repair in a satellite RNA of Cucumber mosaic virus (CMV) strain Q (Q(sat)) by a heterologous Tomato aspermy virus (TAV), a set of biologically active agrotransformants corresponding to the three genomic RNAs of TAV was developed. Analysis of Nicotiana benthamiana plants agroinfiltrated with TAV and either wild type or each of the six 3 deletion mutants of Q(sat) revealed that (i) heterologous replicase failed to generate Q(sat) multimers, a hallmark feature of homologous replicase dependent replication of Qsat; (ii) manifestation of severe symptom phenotypes and progeny analysis suggested that heterologous replicase was competent to repair Q(sat) deletion mutants lacking up to 313 nucleotides (nt) but not beyond and (iii) comparative in silico analysis indicated that the 3 secondary structural features of the repaired Q(sat) progeny from heterologous vs homologous driven replicases are remarkably very similar. The significance of these observations is discussed

Detection of the three agents of groundnut rosette disease (groundnut rosette assistor virus, groundnut rosette virus and its satellite RNA) in plants and vectoraphids by reverse transcription-polymerase chain reaction (RT-PCR) is reported. Three procedures for extraction of total RNA from groundnut were tested, of which two were found to be useful in giving RNA of sufficient quality for RT-PCR. Of these two, the total RNA extraction kit supplied by Qiagen was found to be the most versatile for extraction of all three agents from individual vector aphids (Aphis craccivora). Both groundnut rosette assistor virus and groundnut rosette virus could be detected from total RNA extracted from a single aphid that had been exposed to either green or chlorotic rosette-infected groundnut plants. They could be detected in aphids stored in 70% ethanol for up to 30 days at room temperature. However, satellite RNA could be amplified only when total RNA extracted from two or more aphids was used. Groundnut ...
Groundnut (ArachishypogaeaL.) is an economically important edible oilseed legume, grown in western Kenya. Groundnut rosette disease (GRD) is a major constraint in sub-Saharan Africa, which can cause 100% yield losses in a severe epidemic situation. Rosette is transmitted in nature by the viruliferous aphid vector, Aphis craccivoraKoch (Homoptera: Aphididae), in a polycyclic, persistent, circulative and non-propagative manner. The disease is caused by two synergistic viruses; groundnut rosette assistor virus (GRAV, genus Luteovirus) and groundnut rosette virus (GRV, genus Umbravirus) associated with a satellite-ribonucleic acid (Sat-RNA). The GRD viruses occur in two predominant symptom forms; chlorotic rosette and green rosette, which override the isolated occurrence of mosaic rosette symptom. There is not enough information on the occurrence, distribution and diversity of GRAV causing GRD in western Kenya. This study characterized the virus and determined its occurrence, distribution and ...

To determine the structural requirements for cucumber mosaic virus (CMV) satellites to elicit lethal tomato necrosis, three satellite variants D, S and Y were used in the construction and cloning of chimeric cDNAs. D and S are necrogenic and non-necrogenic prototype variants, respectively, and Y possesses the 3′ conserved necrosis-determining region but does not cause lethal tomato necrosis. Its 5′ half harbours an insertion/deletion region that results in a molecule about 30 nucleotides longer than other variants. Tomato bioassays were conducted with RNA transcripts of all six chimeric combinations of the 5′ and 3′ halves of the three satellite variants divided by a common restriction site, as well as with a mutated chimera. None of the chimeras containing the 5′ half of Y induced lethal necrosis in tomato even when their 3′ halves were that of the D variant with the conserved necrogenic element. Chimeras with the 3′ half of Y elicited only partial or restricted necrosis which was much
Groundnut Rosette Virus disease (GRD) has long been regarded a major limiting biotic constraint to groundnut production in Sub-Saharan Africa (SSA). The disease is caused by a complex of three viral components that interact in a synergistic fashion resulting into severe crop losses. A study was conducted to better understand the genetics of inheritance of GRD resistance. Nineteen groundnut genotypes among which twelve F2 families populations arising from a 3x4 North Carolina II mating design, were evaluated for their percentage disease severity (PDS) and incidence (PDI). There was significant genetic variability for resistance to GRD among the materials studied with more significant additive gene action as compared to non additive. However, since specific combining ability effects were not so consistent among the F2 family populations, evaluation and testing of progenies alongside with their parents would be more meaningful and selection in the early generations would be the most effective ...
With the significant increase in small satellite activities and projects in Europe, the US, Asia, and other parts of the world, the availability of regular, affordable access to space for small satellites becomes even more critical than before. Obviously, there are many complicating factors in arranging a ride for your small satellite. These can be technical and programmatic mismatches between the available launch opportunity and the small satellite mission objectives and planning. But (more) often these complicating factors also relate to export restrictions, political considerations, lack of standardization or a mismatch in requirements and expectations between the small satellite developer and the launch provider or primary customer. Considering the number of rocket launches per year, one might expect sufficient excess capacity on board these launch vehicles to easily accommodate a large number of small satellites as auxiliary or piggyback payloads, In practice it is actually quite difficult to
McLean, VA and Englewood, CO - June 29, 2010 - XStreamHD, an emerging leader in the delivery and distribution of Full HD entertainment directly to the home, announced that it has entered into a long-term satellite service agreement with EchoStar Satellite Services L.L.C., a subsidiary of EchoStar Corporation (Nasdaq: SATS).

We are not going to be stampeded or blackmailed with how amateur the Chinese companies are in satellite manufacture or launching but if they are the ones that can open our engineers eyes in this technology, let them have it, he added. Gwandu noted that even satellites built by world renowned corporations also fail.. The satellite industry, like others, has its share of mishaps. Hotbird 3, owned and operated by Eutelsat had its solar array damaged in October 2006. Japan Aerospace Exploration Agency lost its MTSAT 1R in April 2006. The satellite failed to operate and lost attitude on 16 April. However, it was regained 16 hours later.. This happened about a year after it was originally launched. PanAmSat lost its PAS 6 communication satellite in 2004 due to significant loss of power. It was built by the highly reputable SpaceSystems/Loral (SS/L).

The Oko system forms a part of the Russian intercontinental ballistic missiles detection and early warning system. It was composed of three satellites out of which only one has now been left in orbit. Despite the pre-scheduled launches of the system apparatuses in 2007 and 2008, the satellites went out of order fairly shortly: the contact with both first and second satellites was lost in 2013-2014. That period of time was marked by a number of catastrophes in which Russian recon satellites de-orbited quite massively.. Naturally, the Russian Ministry of Defense immediately reacted to another falling, having announced that the de-orbiting of the satellite was timely and pre-scheduled. Well, it would have been surprising if the Russian military body commented on another their shameful fail in any other way. Since 2015, Russians have been implementing new Tundra system designed to replace The Eye. This system is described as being more precise, powerful and allowing military not only to detect ...
