The homeobox gene MaH1 governs microcycle conidiation for increased conidial yield by mediating transcription of conidiation pattern shift-related genes in Metarhizium acridum

Applied Microbiology and Biotechnology, 2019
Conidiation capacity and conidial quality are very important for the production and application of mycopesticides. Most filamentous ascomycetous fungi have two distinct patterns of conidiation. Conidiation through microcycle conidiation proceeds to more rapidly achieve a maximum of conidial yield than normal conidiation and hence is of greater merit ...

Microcycle conidiation in Penicillium urticae: an ultrastructural investigation of conidiogenesis

Canadian Journal of Microbiology, 1975
A cultivation system has been developed for Penicillium urticae which yields 'microcycle' conidiation in submerged culture. Spherical growth of spores was initiated by incubation at 37 °C in a growth-favoring medium. Transfer of these enlarged spores to a nitrogen-poor medium at 35 °C results in synchronous germination and limited outgrowth followed ...

Microcycle conidiation by regenerating protoplasts of Aspergillus awamori

Experimental Mycology, 1982
Abstract Enzymatically prepared protoplasts of Aspergillus awamori regenerate cell walls and become resistant to osmotic shock within 4 hours after their removal from the digestion mixture. By 6 hours, germ tubes have been formed by many of the reverting protoplasts.

Effect of metabolic inhibitors on microcycle conidiation of Aspergillus niger

Transactions of the British Mycological Society, 1979
The effects of several metabolic inhibitors on normal spore germination and microcycle conidiation in Aspergillus niger van Teigh. were examined. Normal spore germination showed the greatest susceptibility to inhibition, followed by conidiation, while giant cell formation (vegetative growth) was the least susceptible.

Effect of medium composition on microcycle conidiation in Aspergillus niger

Transactions of the British Mycological Society, 1986
The effect of the physical and chemical environment on microcycle conidiation in A. niger has been studied in a 5 1 fermenter. It appears that temperature is the critical factor for giant-cell formation and germ-tube suppression, the addition of CO2 having little effect.

Microcycle conidiation in the entomopathogenic fungus Beauveria bassiana bals. (vuill.)

Process Biochemistry, 1999
Abstract The present work documents the experimental conditions under which the three types of two local strains of Beauveria bassiana conidia enter into a microcycle conidiation process (conidiation without vegetative phase). Different levels of different C (glucose and starch) and N sources (KNO3, NH4Cl, glutamate and peptone) were added to a basal

Differential deoxyribonucleic acid synthesis during microcycle conidiation in Neurospora crassa

Archives of Microbiology, 1978
In conidia of Neurospora crassa germinating at 25 degrees C, DNA synthesis measured by incorporation of tritiated adenosine reaches a maximum soon after the outgrowth of the germ tube (6--7 h after inoculation). In conidia heat-treated at 46 degrees C (for 15 h), a maximum of incorporation of the DNA precursor occurs already 1 h after inoculation, then

Microcycle conidiation and medusa head conidiophores of aspergilli on indoor construction materials and air filters from hospitals

Mycologia, 2007
Microcycle conidiation and microniche colonization by aspergilli was observed in-situ on various indoor construction and finishing materials. Microcycle conidiation, direct conidiogenesis from a conidium or spore with minimal intervening hyphal development, for several decades has been considered a survival mechanism during stress for a variety of ...

Microcycle conidiation and the conidial properties in the entomopathogenic fungus Metarhizium acridum on agar medium

Biocontrol Science and Technology, 2010
Abstract Conidiation of the entomopathogenic fungus Metarhizium acridum on agar media was investigated. M. acridum CQMa102 exhibits two different conidiation patterns on agar media: normal conidiation in which conidia are formed on extended hyphae and microcycle conidiation in which conidiation occurs directly after conidia germination.

Dimorphism and microcycle conidiation of Pseudocercospora pseudostigmina‐platani conidia from American sycamore

Forest Pathology, 2022
Abstract In this study, the micromorphology and surface details of Pseudocercospora pseudostigmina‐platani conidia were investigated on American sycamore ( Platanus occidentalis ) leaves. Sooty films were collected from diseased leaves
