Microcycle conidiation in Penicillium urticae: an ultrastructural investigation of spherical spore growth

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 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 resulted in synchronous germination and limited ...

Heat-induced changes in respiratory pathways and mitochondrial structure during microcycle conidiation of Neurospora crassa

Archives of Microbiology, 1980
Changes in both respiratory pathways and mitochondrial structure of Neurospora crassa occurred under conditions of microcycle conidiation. Upon heat-treatment at 46 degrees C, conidia developed a highly cyanide-insensitive, hydroxamate-sensitive respiration associated with morphological alterations in mitochondrial membranes; such changes were time ...

DNA, RNA and protein biosynthesis during microcycle conidiation in Aspergillus niger

Transactions of the British Mycological Society, 1978
The levels of DNA, RNA and protein were determined at different stages throughout microcycle conidiation in Aspergillus niger van Tiegh. The period of maximum accumulation of these cellular components occurred during spore growth rather than the period of conidiophore outgrowth.

Stress Induced Microcycle Conidiation in Fungi

Journal of Biomedical Sciences and Biotechnology Research
Microcycle conidiation (MC) is a kind of survival mechanism in fungi reproducing asexually to produce a lot of spores in stress to withstand themselves unfavorably. In MC, new conidia are often formed on conidiophores from the parent conidia with the arrest of a mycelial phase. The conidia thus produced are synchronous in nature.

In vitro growth and microcycle conidiation of Idriella bolleyi, a biocontrol agent of cereal pathogens

Mycological Research, 1994
The minimum nutrient requirements for growth of Idriella (= Microdochium ) bolleyi in shaken liquid culture were mineral salts, nitrate nitrogen, glucose and thiamine. Typical batch culture kinetics were displayed in this medium and were assessed by culture turbidity when sodium alginate was used to induce growth by dispersed mycelia. Conidia were

D-Glucose soluble starch, a novel medium for inducing microcyclic conidiation in Aspergillus

Mycological Research, 1992
d -Glucose soluble starch (D-GSS) is a new growth medium for the induction of microcyclic conidiation in Aspergillus . Four different aspergilli, A. niveus, A. tamarii, A. terreus and Aspergillus sp. produced conidiophores, vesicles, sterigmata and conidia within 18–24 h of incubation with no intervening vegetative mycelium.

Microcycle conidiation induced by partial nitrogen deprivation in Neurospora crassa

Canadian Journal of Microbiology, 1984
Premature macroconidiation occurs at the tips of germ tubes elongated as presumptive conidiophores from macroconidia of Neurospora crassa incubated at 37 °C in nitrogen-limited shaken cultures. The use of different nitrogen sources indicated that this differentiation process could be induced by ammonium deprivation.

MaNrg1, a transcriptional regulator, negatively regulates the UV-B tolerance and governs the microcycle conidiation in Metarhizium acridum

Pesticide Biochemistry and Physiology
Microcycle conidiation (MC) displayed a great potential for enhancing the yield and quality of conidia in entomopathogenic fungus. Elucidating the molecular regulatory mechanisms of MC is helpful to improve mycoinsecticide efficacy through optimized conidiation.

Mutants with continuous microcycle conidiation in the filamentous fungus Fusarium solani f. sp. pisi

Molecular and General Genetics MGG, 1984
A method of repeated mutation induction and subsequent selection was used to obtain mutants with microcycle conidiation, mc, in Fusarium solani f. sp. pisi. Wild-type, wt, Fusarium has a filamentous (hyphal) growth in a three-stage, conidium—hypha—conidiophore (phialid) vegetative life cycle.
