Phialide - an overview | ScienceDirect Topics
Phialides are generally flask-shaped, comprising a cylindrical basal part and a distinct neck, or lanceolate (with a narrow basal part tapering to a pointed apex). Conidia are produced in long dry chains, divergent, or in columns, are globose, ellipsoidal, cylindrical, or fusiform, hyaline or greenish, smooth or rough-walled.
Penicillium | Mycology | University of Adelaide
Culture of Penicillium spp. Colonies are usually fast growing, in shades of green, sometimes white, mostly consisting of a dense felt of conidiophores. Microscopically, chains of single-celled conidia are produced in basipetal succession from a specialised conidiogenous cell called a …
Estimated divergence times of Hirsutella (asexual morphs) in ...
2018年7月13日 · The differentiation of the phialides structures in the major clades demonstrated a clear evolutionary path of Hirsutella (asexual morph) species, which exhibited two trends depending on the host size.
Conidiophores - an overview | ScienceDirect Topics
Branches and phialides are broad or inflated, relatively short • Phialides on the branches are distributed in crowded verticils • Few species have the extension of sterile conidiophore • Many of them produce compact conidiogenous pustules by anatomizing with adjacent conidiophores (Rifai, 1969) (T. hamatum, T. harzianum, T. piluliferum, T ...
Conidiogenesis: Its Evolutionary Aspects in the Context of a
Phialides , an item found in members of most groups other than Onygenales and Saccharomycetes, are equally used for airborne and moisture-borne conidiation, but very rarely for intramatrical forms, the exception being found in a …
Fungal Morphogenesis, from the Polarized Growth of Hyphae …
2018年4月11日 · By other budding processes, each metula develops two uninucleated conidiogenic cells called phialides. Each phialide produces about 100 uninucleated conidia through periodic budding cycles ( Fig. 8 ).
Characterization of phiA, a gene essential for phialide …
2003年12月1日 · In the present study we have characterized the phiA gene of A. nidulans with respect to its mutant phenotype, growth effects, and localization in fungal tissue. This gene encodes a protein that is essential for asexual development and normal growth, and is probably universal in filamentous Ascomycetes (Fig. 1).
Microbiology Journal - Wiley Online Library
2012年6月1日 · Introduction. The fungal colony typically consists of a network of polarized hyphae known as a mycelium, which in turn supports the development of reproductive structures that bear spores. Among the myriad of distinct cell types produced during development, one of the most important is the phialide.
(PDF) Holoblastic phialides - ResearchGate
1982年8月1日 · Abstract and Figures. Holoblastic and enteroblastic forms of development in conidial fungi appear to intergrade in species producing annellides. Analysis of this intergradation shows that it...
A taxonomic review of Penicillium species producing …
2016年2月8日 · We delineate species using phylogenies based on the nuc rDNA internal transcribed spacer region (ITS), and partial BenA (β-tubulin), CaM (calmodulin) and RPB2 (RNA polymerase II second largest subunit) gene sequences, as well as morphological characters.
