The Production of Conidiophores and Conidia by Newly Germinated Conidia of Aspergillus niger (Microcycle Conidiation) [PDF]

open access: yesJournal of General Microbiology, 1971
SUMMARY: The ability of Aspergillus niger conidia to produce conidiophores after germination in shaken culture at 30° was stimulated by the inclusion of glutamate in the medium. Incubation of the conidia at 35° to 41° increased swelling of the conidia and also the proportion which produced conidiophores.

Transformation of Epichloë typhina by electroporation of conidia [PDF]

open access: yesBMC Research Notes, 2011
Abstract Background Choke, caused by the endophytic fungus Epichloë typhina, is an important disease affecting orchardgrass (Dactylis glomerata L.) seed production in the Willamette Valley. Little is known concerning the conditions necessary for successful infection of orchardgrass by E. typhina.

Biocontrol and Action Mechanism of Bacillus subtilis Lipopeptides’ Fengycins Against Alternaria solani in Potato as Assessed by a Transcriptome Analysis

open access: yesFrontiers in Microbiology, 2022
Alternaria solani is an airborne fungus and the primary causal agent of potato early blight worldwide. No available fungicides that are both effective and environmentally friendly are usable to control this fungus.

Entomophthora Conidia in the Air-spora [PDF]

open access: yesJournal of General Microbiology, 1970
SUMMARY: At Silwood Park, Berkshire, in 1958, the largest concentration of each of five ‘types’ of Entomophthora conidia in the air typically occurred at 05.00 to 07.00 h. and was associated with humid air and sunrise. The smallest concentration occurred between 14.00 and 17.00 h. when the air was usually driest.

Interactions Between Spore Morphogenetic Mutations Affect Cell Types, Sporulation, and Pathogenesis in Magnaporthe grisea

open access: yesMolecular Plant-Microbe Interactions, 1998
We have previously defined four single-gene mutations, con1, con2, con4, and con7, that control various stages of spore morphogenesis in the rice blast fungus.

An LaeA- and BrlA-Dependent Cellular Network Governs Tissue-Specific Secondary Metabolism in the Human Pathogen Aspergillus fumigatus

open access: yesmSphere, 2018
Biosynthesis of many ecologically important secondary metabolites (SMs) in filamentous fungi is controlled by several global transcriptional regulators, like the chromatin modifier LaeA, and tied to both development and vegetative growth.

Suppression of Aspergillus fumigatus Germination by Neutrophils Is Enhanced by Endothelial-Derived CSF3 Production

open access: yesFrontiers in Microbiology, 2022
Infection with Aspergillus fumigatus can cause life-threatening diseases in immunocompromised patients with an unacceptable mortality rate. Angioinvasion is one of the features of severe invasive aspergillosis.

Novel Treatment Approach for Aspergilloses by Targeting Germination

open access: yesJournal of Fungi, 2022
Germination of conidia is an essential process within the Aspergillus life cycle and plays a major role during the infection of hosts. Conidia are able to avoid detection by the majority of leukocytes when dormant.

Trichoderma asperelloides Spores Downregulate dectin1/2 and TLR2 Receptors of Mice Macrophages and Decrease Candida parapsilosis Phagocytosis Independent of the M1/M2 Polarization

open access: yesFrontiers in Microbiology, 2017
The intensive use of pesticides to control pests in agriculture has promoted several issues relating to environment. As chemical pesticides remain controversial, biocontrol agents originating from fungi could be an alternative.

Blastospores from Metarhizium anisopliae and Metarhizium rileyi Are Not Always as Virulent as Conidia Are towards Spodoptera frugiperda Caterpillars and Use Different Infection Mechanisms

open access: yesMicroorganisms, 2023
Infective conidia from entomopathogenic fungi are widely used to control insect pests. Many entomopathogenic fungi also produce yeast-like cells called blastospores under specific liquid culture conditions that can directly infect insects.
