Abstract

Plant disease resistance (R) genes confer effector-triggered immunity (ETI) to pathogens carrying complementary effector/avirulence (Avr) genes. They are traditionally recognized to function at translational and/or posttranslational levels. In this study, however, transcriptional and posttranscriptional regulation of Cf-9, a tomato R gene conferring resistance to leaf mould fungal pathogen carrying Avr9, was demonstrated. Expression of the Cf-9 gene was 10.8-54.7 folds higher in the Cf-9/Avr9 tomato lines than in the Cf-9 lines depending on the seedling age, indicating that the Cf-9 gene expression was strongly induced by Avr9. Moreover, expression of the Cf-9 gene in the 5-day-old Cf-9/Avr9 seedlings at 33 °C was approximately 80 folds lower than that at 25 °C, and was enhanced by 23.4 folds at only 4 h post temperature shift from 33 °C to 25 °C, demonstrating that the Avr9-mediated induction of the Cf-9 gene expression is reversibly repressed by high temperature. Expression of the Cf-9 gene in the Cf-9 seedlings was similarly affected by temperature as in the Cf-9/Avr9 seedlings, implying that the genetic control of temperature sensitivity of the Cf-9 gene expression is epistasis to its Avr9-mediated induction. Additionally, ...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.
