Light-independent conidiation in Trichoderma spp.: a novel approach to microcycle conidiation

World Journal of Microbiology and Biotechnology, 1993
Microcycle conidiation in Trichoderma hamatum and T. harzianum has been achieved in complete darkness for the first time. The time required for mass conidiation without intervening vegetative growth was decreased to 24 h instead of 6 to 7 days. The conidia produced by microcycle conidiation were viable and had pigmentation and antagonistic behaviour ...

Arginine metabolism governs microcycle conidiation by changing nitric oxide content in Metarhizium acridum

Applied Microbiology and Biotechnology, 2023
Microcycle conidiation commonly exists in filamentous fungi and has great potential for mass production of mycoinsecticides. L-Arginine metabolism is essential for conidiation and conditional growth and virulence, but its role in microcycle conidiation has not been explored.

Mmc, a gene involved in microcycle conidiation of the entomopathogenic fungus Metarhizium anisopliae

Journal of Invertebrate Pathology, 2010
Microcycle conidiation is a survival mechanism for some fungi encountering unfavorable conditions, in which asexual spores germinate secondary spores directly without formation of mycelium. Here, we isolated a microcycle conidiation associated gene, Mmc, from Metarhizium anisopliae and obtained its full length of cDNA and DNA sequence.

Microcycle conidiation inPenicillium italicum

Experimental Mycology, 1983
Abstract Penicillium italicum readily conidiates in submerged (shaken) culture in a common carbohydrate-mineral salts medium. At 25°C formation of penicilli is completed within 40 h after inoculation of the nutrient medium with conidia. In medium of proper composition all conidia undergo a true microcycle conidiation, i.e., conidiogenesis ...

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.

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

Spore Germination and Microcycle Conidiation of Two Penicillia in Soil

Mycologia, 1984
Laboratory-produced spores of two penicillia isolated from soil were placed onto PVC membrane filters, inserted into microholders and buried in the A horizon of an oak-birch forest. After various intervals of time incubation filters were retrieved, stained, and mounted on glass slides for examination.

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 ...
