Light-independent conidiation in Trichoderma spp.: a novel approach to microcycle conidiation
World Journal of Microbiology and Biotechnology, 1993Microcycle 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 ...

Polyamines as Modulators of Microcycle Conidiation in Aspergillus Flavus [PDF]
Microbiology (United Kingdom), 1996 Since polyamines (PAs) play a potential role in the regulation of growth and developmental processes in a wide variety of organisms, we have examined the influence of the PAs putrescine (Put) and spermidine (Spd) and the PA biosynthetic inhibitors α-difluoromethylornithine (DFMO), α-difluoromethylarginine (DFMA), methylglyoxal bis-(guanylhydrazone ...

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, 2010Microcycle 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, 1983Abstract 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 ...

Microcyclic Conidiation Cycles in Epichloe typhina
Mycologia, 1991Germination of ascospores in Epichloe typhina was described earlier as iterative germination in which each part spore of an ascospore germinated and produced conidia without an intervening mycelial phase. In the present study it was determined that the conidia produced by iterative germination also undergo an additional series of microcyclic ...

Canadian Journal of Microbiology, 1975
A cultivation system has been developed for Penicillium urticae (NRRL 2159A) which yields 'microcycle' conidiation in submerged culture. Spherical growth of conidia was initiated by incubation at 37 °C in a growth-favoring medium. Transfer of these enlarged conidia to a nitrogen-poor medium at 35 °C resulted in synchronous germination and limited ...

Spore Germination and Microcycle Conidiation of Two Penicillia in Soil
Mycologia, 1984Laboratory-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 in Hirsutella thompsonii
Canadian Journal of Microbiology, 1988A fermenter method for producing conidiospores of the acarine pathogen, Hirsutella thompsonii, was developed using a strain able to produce microcycle conidiation in submerged culture. The morphological changes occurring during microcycle formation were followed under electron microscopy.
