The peptides of the hyphal wall of Neurospora crassa.
The peptides of the hyphal wall of Neurospora crassa have been studied to determine their physical characteristics. We have removed these peptides from the wall by treatment with 05 M-NaOH and shown by DEAE cellulose chromatography that there are five major fractions present. Amino acid analysis showed distinct differences in primary structure between these fractions but similarities in the pro...
متن کاملCalcium gradient dependence of Neurospora crassa hyphal growth.
A tip-high cytoplasmic calcium gradient has been identified as a requirement for hyphal growth in the fungus Neurospora crassa. The Ca2+ gradient is less steep compared to wall vesicle, wall incorporation and vesicular Ca2+ gradients, but this can be explained by Ca2+ diffusion. Analysis of the relation between the rate of hyphal growth and the spatial distribution of tip-localized calcium indi...
متن کاملDisseminated Geotrichum candidum infection.
The pathogenicity of the fungus Geotrichum candidum in humans has not been clearly defined. A patient with acute leukemia who developed a fatal disseminated G. candidum infection while neutropenic is described. At autopsy examination, this patient was misdiagnosed on the basis of histopathology as having disseminated candidiasis until G. candidum was isolated from postmortem culture specimens. ...
متن کاملLive-cell imaging of vegetative hyphal fusion in Neurospora crassa.
The process of hyphal fusion (anastomosis) in growing colonies of Neurospora crassa, stained with the membrane-selective dyes FM1-43 and FM4-64, was visualized by confocal microscopy. Time-lapse, live-cell imaging illustrated the dynamics of hyphal growth and anastomosis during its pre-contact, contact and post-contact, and post-fusion stages. Fusion-competent hyphae were morphologically distin...
متن کاملThe roles of Ca2+ and plasma membrane ion channels in hyphal tip growth of Neurospora crassa.
Growing hyphae of the ascomycete fungus Neurospora crassa contained a tip-high gradient of cytoplasmic Ca2+, which was absent in non-growing hyphae and was insensitive to Gd3+ in the medium. Patch clamp recordings in the cell-attached mode, from the plasma membrane of these hyphae, showed two types of channel activities; spontaneous and stretch activated. The spontaneous channels were identifie...
