Summary
Researchers identified Arabis mosaic virus (ArMV) as a suitable pathogen for laboratory studies in the model legume Lotus japonicus. Different Lotus species and accessions showed varying susceptibility, impacting virus multiplication and plant response.
Area of Science:
- Plant virology
- Legume research
- Molecular plant pathology
Background:
- The model legume Lotus japonicus is a valuable system for plant science research.
- Identifying suitable pathogens is crucial for establishing robust laboratory models.
- Arabis mosaic virus (ArMV) is a known plant pathogen with a broad host range.
Purpose of the Study:
- To identify a suitable virus pathogen for laboratory studies in Lotus japonicus.
- To evaluate the susceptibility of different Lotus species and accessions to ArMV.
- To characterize virus multiplication, persistence, and plant responses in Lotus.
Main Methods:
- Screening of various Lotus species and accessions for susceptibility to ArMV.
- Inoculation with Arabis mosaic virus derived from barley (ArMV-ba).
- Monitoring virus multiplication, persistence, and plant reactions in infected tissues.
Main Results:
- Differential susceptibility to ArMV was observed across Lotus species and accessions.
- Virus multiplication and persistence within Lotus tissues were confirmed.
- Varied plant responses to ArMV infection were documented.
Conclusions:
- ArMV is a suitable pathogen for laboratory investigations in Lotus japonicus.
- Geographical origin may influence the susceptibility of Lotus accessions to ArMV.
- Further studies can leverage this model for understanding plant-virus interactions.

01:29Subviral Agents
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
