Abstract
During mating, Saccharomyces cerevisiae cells must degrade the intervening cell wall to allow fusion of the partners. Because improper timing or location of cell wall degradation would cause lysis, the initiation of cell fusion must be highly regulated. Here, we find that yeast cell fusion is negatively regulated by components of the cell wall integrity (CWI) pathway. Loss of the cell wall sensor, MID2, specifically causes “mating-induced death” after pheromone exposure. Mating-induced death is suppressed by mutations in cell fusion genes (FUS1, FUS2, RVS161, CDC42), implying that mid2Δ cells die from premature fusion without a partner. Consistent with premature fusion, mid2Δ shmoos had thinner cell walls and lysed at the shmoo tip. Normally, Cdc42p colocalizes with Fus2p to form a focus only when mating cells are in contact (prezygotes) and colocalization is required for cell fusion. However, Cdc42p was aberrantly colocalized with Fus2p to form a focus in mid2Δ shmoos. A hyperactive allele of the CWI kinase Pkc1p (PKC1*) caused decreased cell fusion and Cdc42p localization in prezygotes. In shmoos, PKC1* increased Cdc42p localization; however, it was not colocalized with Fus2p or associated with cell death. We conclude that Mid2p and Pkc1p negatively regulate cell fusion via Cdc42p and Fus2p.

Abstract
AIMS (i) To analyse the increase in calcium ion uptake caused by several cationic dyes on Candida albicans, (ii) to postulate a mechanism, (iii) to define the effects of Zn ions on the phenomenon, and (iv) to propose the use of the dyes or their derivatives against C. albicans. METHODS AND RESULTS Cells were grown in yeast peptone dextrose medium and starved. We measured the hydrophobic solvent/water partition coefficients and the dyes uptake by the cells and found no correlation with their hydrophobicity. Most of the dyes caused an increase in K+ efflux (in correlation with a decrease in 86 Rb+ uptake), and a raise in Ca2+ uptake except for those used as Zn salts, but not of their HCl salts. Respiration and acidification of the medium were modified only with few dyes and interestingly, when exposing cultures to nile blue, neutral red and toluidine blue ZnCl2 a decrease in C. albicans growth was observed. CONCLUSIONS We propose a general mechanism for the stimulation of Ca2+ uptake by the dyes used. Some of the dyes tested might be used as agents against C. albicans, probably combined with other agents. Moreover, the effects of Zn ions on Ca2+ uptake and on cell growth open possibilities of further studies, not only of their effects, but also of the mechanism of Ca2+ transport in C. albicans and other yeasts. SIGNIFICANCE AND IMPACT OF THE STUDY This study, in conjunction with previously published results, contribute to the basic research regarding ion transport in C. albicans and the role of zinc in this process. Besides, suggests the additional use of dyes, along with other antifungals agents, as combined therapy against candidiasis. Derived dyes from those used also might be possible therapeutic agents against this disease.

Abstract
Malachite green, an N-methylated diaminotriphenylmethane dye, is used primarily as a therapeutic agent in aquaculture. In solution, the dye exists as a mixture of the cation (chromatic malachite green) and its carbinol base, with the ratio depending on the pH of the solution; the dye also can undergo chemical and metabolic reduction to a leuco derivative. Analysis offish tissue after exposure to malachite green indicates the presence of both chromatic and leuco forms, with the latter having a much longer tissue half-life. Malachite green intercalates with DNA, with a preference for A:T-rich regions, and the leuco derivative bears a structural resemblance to carcinogenic aromatic amines that can form covalent DNA adducts. Malachite green is mutagenic in Salmonella typhimurium TA98 in the presence of an exogenous metabolizing system. In mammalian cells, it shows marked cytotoxicity and the ability to induce cell transformation and lipid peroxidation. Results from carcinogenicity bioassays with malachite green have been equivocal; however, it appears to act as a tumor promoter, perhaps because of its ability to induce the formation of reactive oxygen species. These characteristics, plus its close structural similarity to carcinogenic triphenylmethane dyes (e.g., gentian violet) suggest that additional data are required to determine if human exposure to malachite green results in adverse health effects.

Abstract
Potassium efflux in yeast induced by several cationic compounds showed different characteristics. All of the observed efflux required glucose as substrate at the concentrations used. For most of them, the phenomenon required binding of the cationic compound to the cell surface and increased with the negative cell surface charge, and for all the compounds tested, it depended on a metabolizable substrate. Efflux induced with terbium chloride appeared more likely due to the function of a K+/H+ antiporter. With DEAE-dextran and dihydrostreptomycin, potassium efflux was dependent on the cell potassium content and was also sensitive to osmotic changes of the medium. DEAE-dextran-provoked efflux was not due to cell disruption. Dihydrostreptomycin seemed to activate a potassium efflux system which could not be studied in isolation, but its inhibition of potassium uptake may also be involved. Except for cells treated with ethidium bromide, no appreciable cell disruption was observed. The potassium efflux observed appears to be a membrane phenomenon reversible after washing with magnesium chloride.

Abstract
Photodynamic treatment of Kluyveromyces marxianus with the sensitizer Toluidine blue leads to the loss of colony forming capacity. In this paper, the influence of this treatment on the barrier properties of the plasma membrane has been studied. Photodynamic treatment with the dye Toluidine blue resulted in efflux of potassium ions and E260-absorbing material. Moreover, cells became stainable with erythrosine. It is concluded that the permeability change induced by photodynamic treatment proceeds in an all-or-none fashion. Treatment of this yeast strain, with the dye and light, also induced a diminution of the cell volume. This process is most likely not coupled to the cellular potassium content, but rather to the integrity of the vacuole. These data suggest that the vacuole has an important function in the maintenance of cell volume. Finally, it was observed that the loss of cell viability was not induced by the all-or-none loss of barrier properties.

Abstract
An efflux of potassium ions was demonstrated in mutants of yeast cells lacking a functional high affinity carrier system for monovalent cations. This efflux showed the following characteristics: (a) It was stimulated by the presence of a substrate, either glucose or ethanol. (b) It was stimulated by several cationic organic molecules, such as ethidium bromide, dihydrostreptomycin, diethylaminoethyldextran, and also by trivalent cations, such as Al3+ and lanthanides; this stimulation also depended on the presence of a substrate. (c) K+ efflux was decreased in yeast mutants with decreased ATPase activity, which generated a lower membrane potential. (d) Although the efflux appeared to be of an electrogenic nature, producing hyperpolarization of cells, it was accompanied by the efflux of phosphate, probably as an anion partially compensating for the large amount of cations leaving the cell. (e) K+ efflux was also accompanied by an uptake of protons. (f) The efflux appeared more clearly in cells grown in YPD medium, and not in more complex media nor in the same YPD medium if supplemented with Ca2+ or Mg2+. Efflux of monovalent cations produced by Tb3+ and organic cationic agents was also demonstrated in wild type strains. This efflux system appears to be, at least partially, electrogenic, but seems to be also an exchange system for protons and to function as a symport with phosphate; it may be involved in the regulation of the internal pH of the cell, and appears to be regulated by its link to the energetic status of the cell, probably through the membrane potential.

Abstract
In experiments dealing with the effect of xenobiotics upon the efflux of K+ from yeast cells, one should be aware that when this efflux proceeds via an all-or-none process, the K+ being released from the intoxicated cells can again be accumulated into the still unaffected cells. Therefore, the measured net efflux of K+ will be less than the efflux from the intoxicated cells. The difference between these two magnitudes can be minimalized by incubating the cells for only a short period and on applying yeast densities that are not too high. When the cells are permeabilized relatively slowly but ultimately to a great extent, the kinetics of K+ efflux may be quite complicated.

Abstract
Mild sonication was used to obtain single cell suspensions of Paracoccidioides brasiliensis. These cells were intact by microscopic criteria. Direct cell counts in a given inoculum and colony formation on various media were used to determine plating efficiency. Sonicated and nonsonicated cell suspensions were used to study plating efficiency and to estimated viability by means of vital dyes. Methylene blue Erythrosin B, and Janus green were unreliable when used with P. brasiliensis, but vital dyes were accurate when tested with Candida albicans. Acridine orange gave more meaningful results of viability. Estimates of viability, however, changed significantly as a result of relatively minor alterations in the composition of the suspending medium. In initial experiments, the plating efficiency of P. brasiliensis was dismally low. It descended abruptly with increasing dilution of inoculum. Efficiency was much improved if horse serum was added to brain heart infusion plates or if glucose glycine yeast extract (GGY) plates were incubated at room temperature and mycelial colonies were counted. With the technique we report, current plating efficiency of sonicated suspensions is of the order of 25%. Our results and procedures have an important bearing upon those studies concerned with in vitro killing of P. brasiliensis in suspensions or with isolating this fungus from clinical or environmental specimens.

Abstract
A quantitative technique is presented for differentiating live and dead yeast cells grown in culture through the use of the fluorescent dye acridine orange. The method gives results that correlate well with those of other commonly used vital staining techniques and is free of certain interpretative errors inherent in them. Vital staining of yeasts with acridine orange also allows for more precise assessment of the physiological state of individual cells and the culture as a whole. The progressive senescence of yeast cells in culture can be monitored by the changing staining characteristics of several subcellular organelles. The method is simple and reliable.

Abstract
SUMMARYMutant colonies of yeast are described which varied in colour from blue to green and in intensity of colour when grown on medium containing methylene blue. Blue mutant colonies contained more dead cells, decolorized redox dyes more slowly, had a higher respiratory quotient on glucose containing medium, and absorbed more methylene blue dye than did wild-type. The blue colony phenotype was induced both spontaneously and at high frequency by ultraviolet light and ethylmethane-sulphonate in both haploid and diploid strains. Many of the light-coloured colonies isolated following mutagenic treatment reverted to wild-type when subcultured but most dark-coloured colonies remained stable. Stable blue mutants were shown to arise by mutation of many separate nuclear genes in haploids and were often caused by recessive lethals in diploids.

Abstract
Abstract
Uranyl ions and thorium ions are effective in preventing cytolysis by Toluidine Blue and Azure A because they interfere with dye uptake by the cells. Neither uranyl nor thorium ions prevent the uptake of cetrimide or cetylpyridinium chloride. Cetylpyridinium chloride is capable of releasing previously bound uranyl ions from the cell surface. Anionic groups belonging to lipid constituents of the cell membrane may be involved in the uptake of uranyl and thorium ions as well as in the binding of dye and surfactants cations respectively. Possible cytolytic mechanisms involving polar interactions at the cell surface with lytic cations are discussed.
