“…Similar proliferation of endoplasmic reticulum under anaerobic conditions has been found in root meristems by Wrischer (1960) and Gavaudan, Poussel, and Guyot (1960) and in yeast grown anaerobically (Linnane, Vitols, and Nowland 1962).…”

Ab8tractThe nectary hair cells of Abutilon are particularly rich in mitochondria and endoplasmic reticulum. The vacuoles are initially small but enlarge and coalesce during nectar production when invaginations of the plasmalemma are often present at the tips and at the cross-walls of the hairs. The presence of these invaginations suggests that nectar may be transported through the nectary by a process resembling pinocytosis and exocytosis. Entry of nectar into the hair is restricted to a route through the protoplast of the stalk cell by a cutinized sheath in the outer walls of this cell.Pretreatment of the nectaries in anaerobic conditions or low temperature results in changes in the structure of the endoplasmic reticulum.

“…Configurations with concentric whorls of lamellar membranes apparently are of widespread occurrence in fungi (Blondel and Turian 1960, Carbonell and Pollak 1962, Hairstone 1967, Hyde and Walkinshaw 1966, Linnane et al 1962, McKeen et al 1967, Smith and Marchant 1968, Thomas and Isaac 1967. Although the morphology of these configurations is generally similar, a certain amount of control of the morphology of these configurations is apparently exerted by the fungus species.…”

“…Tubular elements have been previously described in Puccinia graminis tritici (Thomas and Isaac 1967) and in Geotrichum candidum (Hashimoto and Yoshida 1966), but these configurations differ morphologically from those in T. roseum. A mesh-like configuration has been noted in Paracoccidioides brasilensis (Carbonell and Pollak 1962), and a reticulated membrane system has been noted in yeast cells (Linnane et al 1962). …”

“…Such configurations have been observed in animal cells (Clark 1957, Olah and Rohlich 1966, Seljelid 1966, in lima bean cells (Klein and Ben Schaul 1966), in bacteria (Murray 1963, Pontefract et al 1969, Silva 1966, in slime molds (Hohl 1965), and in various fungi (Carbonell and Pollak 1962, Hashimoto and Yoshida 1966, Hyde and Walkinshaw 1966, Linnane et al 1962, Smith and Marchant 1968, Thomas and Isaac 1967. The configurations with concentric whorls of lamellar membranes strongly resemble the concentric membranes found in the myelin sheaths formed by peripheral nerves of vertebrates (Geren 1956).…”

“…In the case of a dermatophyte, however, potassium permanganate fixation did not always result in preserving the structural details of both organelles. Internal Double Membrane A double membranous structure, resembling the endoplasmic reticulum of animal cells, was also noted in several species of fungi (2,11,15,21,22). In certain dermatophytes, T. rubrum, the presence of a much-folded smooth membrane, which traverses the cytoplasm and is reminiscent of the endoplasmic reticulum of higher animals, has been reported (3,7,17).…”

A rapid progress made for ultrathin sectioning technique in electron microscopy has contributed much to the analysis of microbial cell structures. Recently, several papers (3,(7)(8)(9)17,18,23) have appeared on the subject of electron microscopic studies of certain dermatophytes, and the structural details of fungal cells have been exposed to some extent through electron microscopy of ultrathin sections. However, the published electron micrographs of the organism, especially those in its early stage, were not of sufficient quality to reveal the detail architectures of the fungus. Moreover, the findings of the cell structures hitherto obtained have not been always agreeable among workers, and many problems of the fine structures of the organism still remained to be studied.Since Watson (1958)(25,26) succeeded in enhancing the contrast and resolution in thin sections of biological materials, using stain technique with heavy metals, several modifications(4,10,16) of his method have been reported, and these electron-opaque stains have been widely applied to tissue sections for electron microscopy. Vitols, North and Linnane (1961)(24) first reported that uranyl nitrate treatment of the whole cells of Saccharomyces cerevisiae after permanganate fixation leads to better preservation of the membrane structures and also to an improvement in general contrast. This paper describes some of the fine structures of Trichophyton mentagrophytes as observed chiefly by staining the thin sections of fungus cells with various heavy metals. MATERIALS AND METHODSOrganism employed: A stock culture of Trichophyton mentagrophytes, strain J-812, maintained on a glucose peptone agar at 27 C, was used. This strain was obtained from Dr. T. Tsuchiya, Professor of Juntendo University School of Medicine.Culture media employed: The medium mostly used was a glucose (1 per cent) peptone (1 per cent) water adjusted to pH 5.6.Electron microscopy of thin sections : Hyphal pellets of the strain grown on the medium for 5 to 7 days at 27 C were harvested by centrifugation and washed with sterile veronal-acetate buffer solution several times. These pellets of about 1 to 2 mm in diameter were fixed in 1 per cent osmium tetroxide solution, or 2 per cent potassium permanganate buffered at pH 6.99 with veronal-acetate buffer, for 24 hr at 4 C.
