Subviral Agents

Subviral 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...

Defenses Against Pathogens and Herbivores

Defenses Against Pathogens and Herbivores

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Cell Signaling in Plants

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Viral Structure

Viral Structure

Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Inhibitors of Viral Protein Synthesis

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

Background:

The mechanisms driving symptom development in compatible virus infections remain poorly understood, despite their significant economic impact.
Existing knowledge gaps hinder effective disease management strategies in agriculture and horticulture.

Purpose of the Study:

To elucidate the spatiotemporal sequence of host cell alterations during virus infection.
To identify common molecular and physiological changes induced by different viruses and abiotic stresses.

Main Methods:

Spatial analysis of virus infection fronts in host tissues.
Comparative studies of virus-host interactions across different viral species and hosts.
Analysis of gene expression, host physiology, and cellular ultrastructure changes.

Main Results:

Virus-induced host cell alterations initiate ahead of viral replication and protein accumulation and persist after replication ceases.
A conserved sequence of host responses is observed across different virus-host combinations and abiotic stress.
Virus infection and heat shock share some induced effects but utilize distinct regulatory pathways.

Conclusions:

Virus infections trigger complex, sequential host responses involving gene expression, physiology, and ultrastructure.
Commonalities exist in host responses to diverse viral pathogens, suggesting conserved vulnerability.
Future research should focus on temporal analyses of synchronous infections to fully unravel virus-host dynamics.
