• Abstract

  Visible light is an environmental factor that regulates metabolism, growth, reproduction and even pathogenicity and virulence in different species of fungi. Exposure to light can also pre-adapt fungal structures, such as conidium and mycelia, to future conditions of stress. In the entomopathogenic fungus Metarhizium acridum, exposure to visible light increases the tolerance to UV-B radiat…

• Abstract

  Circadian clocks are important biological oscillators capable of marking the passage of time and were initially described in the model organism Neurospora crassa. In this fungus, the clock regulates a variety of biological processes such as conidiogenesis and metabolism. Circadian clocks are important because they allow the organism to both prepare and respond to environmental changes. Th…

• Abstract

  Toxoplasma gondii is an obligatory intracellular parasite and the causative agent of severe disturbances in human and animals, mostly in pregnant women and immunosuppressed patients. The treatment and prevention for toxoplasmosis are complex and non-completely solved processes, once there are no forms for the effective control of all parasite transmission routes and proliferation. Among t…

• Abstract

  Light response is a wide studied phenomenon in some fungi, such as Neurospora crassa and Aspergillus nidulans. However, the vast majority of fungal species have not had their light response mechanism elucidated. In the entomopathogenic fungus Metarhizium acridum, light is responsible for inducing an increase in tolerance to UV-B (290-315 nm) radiation. Given the potential use of this fung…

• Abstract

  The putative methyltransferase LaeA is the master regulator of secondary metabolism in Aspergillus nidulans. Deletion of LaeA coding gene, laeA, results in decreased production of many secondary metabolites including the aflatoxin precursor sterigmatocystin. LaeA also interacts with the velvet protein VeA, a central regulator of development. VeA-LaeA interaction was found to be necessary …
