The Association of Tobacco mosaic virus with Green Spot of Cured Wrapper Tobacco Leaves

Plant Disease
J A LaMondia

Abstract

Near-isogenic lines of cigar wrapper tobacco resistant or susceptible to Tobacco mosaic virus (TMV) were used to evaluate the association of TMV infection with green spot symptoms in cured leaves. TMV infection, as determined by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA), was detected on susceptible but not resistant plants in field experiments. Green spot severity on cured leaves was greater for susceptible than resistant plants, even when symptoms of TMV were not evident in the field. Some green spots were present on resistant leaves despite the fact that the virus was not detected by ELISA. Resistant and susceptible plants had similar responses to virus infection and similar ELISA detection of TMV when plants were held at continuous temperatures over 28°C in growth chambers. Plant resistance was not compromised in the field in cloth-covered shade tents even when 33.5 of the 96 h immediately following inoculation were above 28°C. Green spot of cured leaves was strongly associated with TMV infection in susceptible plants, even when plants were infected after leaf expansion and mosaic symptoms were not present. Green spot also occurred to a lesser extent and for a limited time in inoculated resistant pla...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
