Abstract

Light is one crucial environmental signal which can determine whether a fungus reproduces asexually or initiates sexual development. Mating in the ascomycete Hypocrea jecorina (anamorph Trichoderma reesei) occurs preferentially in light. We therefore investigated the relevance of the light response machinery for sexual development in H. jecorina. We found that the photoreceptors BLR1 and BLR2 and the light-regulatory protein ENV1 have no effect on male fertility, while ENV1 is essential for female fertility. BLR1 and BLR2 were found to impact fruiting body formation although they are not essential for mating. Quantitative reverse transcription-PCR (qRT-PCR) analyses revealed that BLR1, BLR2, and ENV1 negatively regulate transcript levels of both pheromone receptors as well as peptide pheromone precursors in light but not in darkness and in a mating type-dependent manner. The effect of BLR1 and BLR2 on regulation of pheromone precursor and receptor genes is less severe than that of ENV1 as strains lacking env1 show 100-fold (for ppg1) to more than 100,000-fold (for hpp1) increased transcript levels of pheromone precursor genes as well as more than 20-fold increased levels of hpr1, the pheromone receptor receiving the HPP1 signal...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.
