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 ...

Rhythmic Conidiation in Neurospora crassa

2007
In the filamentous fungus Neurospora crassa the production of asexual spores (conidia) is regulated by its circadian clock. When the fungus is grown on a thin layer of agar medium in long growth tubes (so-called "race tubes"), restricting its growth to one direction only, bright orange bands are clearly visible.

Paedogenetic conidiation inNeurospora crassa

Experimental Mycology, 1983
Abstract Under conditions of growth limitation the germ tubes of Neurospora crassa macroconidia may convert to functional conidiophores with developing chains of viable, new conidia. The induction of this paedogenetic conidiation in liquid culture does not require exposure to high temperature, as reported for conidia of some other ascomycetous fungi,

Conidial anastomosis fusion between Colletotrichum species

Mycological Research, 2004
Colletotrichum lindemuthianum is a pathogen of the common bean plant (Phaseolus vulgaris) causing anthracnose. Large numbers of isolates can rapidly arise with different genetic and chromosomal compositions but their origin is unknown since sexual fruit bodies have only been found in the laboratory.

The molecular mechanisms of conidial germination

FEMS Microbiology Letters, 2001
The asexual spore, or conidium, is critical in the life cycle of many fungi because it is the primary means for dispersion and serves as a 'safe house' for the fungal genome in adverse environmental conditions. This review discusses the physiological process of germination, conidial adhesion and initiation of protein synthesis and also the regulatory ...

Conidial germination patterns in powdery mildews

Mycological Research, 2009
Four conidial germination types namely, polygoni (syn. Pseudoidium), cichoracearum (syn. Reticuloidium), pannosa (syn. Fibroidium) and fuliginea (syn. Magnicellulatae) are commonly used as an aid in the identification of the Oidium anamorphs of powdery mildews. However, results of germination tests and a survey of the literature showed that these types

Two Unusual Conidial Fungi

Mycologia, 1949
It occasionally happens, during the routine of collecting and identifying fungi, that a species having an unusual type of conidium and conidiophore is encountered. The two species given brief consideration herein are believed to be quite unlike any with which even well-trained and experienced students of fungi are acquainted, and consequently they are ...

Microcycle conidiation in Penicillium urticae: an ultrastructural investigation of conidial germination and outgrowth

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 ...
