The effect of age on the structure and compostition of the cell walls of Choanephora cucurbitarum
… fixed thin sections of the 1 day old vegetative hyphae of £. curbitarum revealed the presence of a monolayered cell wall, which upon aging became bilayered. Replicas of acid hydrolysed cell walls demonstrated that both the 1 and 7 day old samples possessed an outer layer which was composed of …

Continuum models for fungal growth
… i.e. an interconnected network of tubes (hyphae) is formed. The mycelium can operate over a very large range of scales (each hypha is only a few microns in diameter, yet mycelia can be kilometres across). Fungi are of fundamental importance to many natural processes: certain species have …

Isolation and characterization of a chitinase-secreting mutant of mortierella pusilla with altered interaction with the mycoparasite piptocephalis virginiana
… auxotrophy, because this strain displayed normal hyphae when glucose was used as the sole carbon source. One interesting phenomenon was that MUT23 showed an extensive clearing zone around the colony on colloidal chitin agar after 20-25 d. On the same conditions, wild type strain did not show this …

Confocal and light microscopy of infection by, and resistance to, Ciborinia camelliae in Camellia species and the potential for biocontrol : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Plant Science (Plant Pathology) at Massey University, Palmerston North, New Zealand
… temperature restricted the growth of penetration hyphae in the tissue and disease development. Absence of free water affected ascospore germination and germ tube penetration when ascospores were inoculated as suspensions using a pipette or atomizer. Ascospores released from apothecia and allowed …

MECHANICAL ABRASION AND ELECTROPORATION IN THE TRANSFORMATION OF INTACT PLEUROTUS OSTREATUS HYPHÆ and NUTRIENT-DEPENDANT RESISTANCE TO HYGROMYCIN B
<p>ABSTRACT 1: Abrasive treatment and subsequent electroporation of the basidiomycete Pleurotus ostreatus in a hypertonic buffer was investigated as a potential method of transforming of intact hyphæ. Mycelia, which are not capable of being transformed via electroporation due to interference by the …

Role of secreted aspartyl proteases in Candida albicans virulence, host immune response and immunoprotection in murine disseminated candidiasis
… or CpG plus Alum as adjuvants. Moreover, as the hypha-associated isoenzyme Sap5 is preferentially expressed during systemic candidiasis, it was also evaluated as target antigen for Candida vaccination, together with Alum or Imiquimod. All these approaches failed in protecting the immunized mice …
