Yeast mating: trying out new pickup lines.
Summary of "Yeast mating: trying out new pickup lines."
Mating of Ascomycete fungi involves chemically distinct pheromones; one partner makes a lipid-modified peptide, the other partner a simple peptide. A new study has now found that this inherent asymmetry may not be necessary.

Medical and Biotech [MESH] Definitions
Genes, Mating Type, Fungal
Fungal genes that mostly encode TRANSCRIPTION FACTORS. In some FUNGI they also encode PHEROMONES and PHEROMONE RECEPTORS. The transcription factors control expression of specific proteins that give a cell its mating identity. Opposite mating type identities are required for mating.
Receptors, Mating Factor
A family of pheromone receptors that were initially discovered in SACCHAROMYCES CEREVISIAE as proteins necessary for fungal conjugation. Each mating factor receptor is expressed in HAPLOID CELLS of a single mating type.
Animals, Inbred Strains
Animals produced by the mating of littermates or siblings over multiple generations. The resultant strain of animals is virtually identical genotypically. Highly inbred animal lines allow the study of certain traits in a relatively pure form. (Segen, Dictionary of Modern Medicine, 1992)
Killer Factors, Yeast
Protein factors released from one species of YEAST that are selectively toxic to another species of yeast.
Cell lines whose original growing procedure consisted being transferred (T) every 3 days and plated at 300,000 cells per plate (J Cell Biol 17:299-313, 1963). Lines have been developed using several different strains of mice. Tissues are usually fibroblasts derived from mouse embryos but other types and sources have been developed as well. The 3T3 lines are valuable in vitro host systems for oncogenic virus transformation studies, since 3T3 cells possess a high sensitivity to CONTACT INHIBITION.
Polarized cell morphogenesis requires actin cytoskeleton rearrangement for polarized transport of proteins, organelles and secretory vesicles, which fundamentally underlies cell differentiation and be...
Prm1 is a pheromone regulated membrane glycoprotein involved in the plasma membrane fusion event of yeast mating. Although this function suggests that Prm1 should act at contact sites in pairs of mati...
Mating decisions usually involve conflict of interests between sexes. Accordingly, males benefit from increased number of matings, whereas costs of mating favour a lower mating rate for females. The r...
Estrous female domestic rabbits (Oryctolagus cuniculus) display scent marking ("chinning") and sexual receptivity. Mating induces ovulation, which occurs approximately 12 h later, and also decreases c...
Yeasts associate with numerous insects, and they can assist the metabolic processes within their hosts. Two distinct yeasts were identified by PCR within the planthopper Perkinsiella saccharicida, the...
This study will examine the effect of red yeast rice extract compared to pravastatin on muscle related complaints in individuals with high cholesterol who have previously been unable to to...
A prospective, non-randomized study to evaluate the performance of the MyoScience Tissue Remodeling Device for the treatment of glabellar lines (frown lines), lateral orbital lines (crow's...
Yeast vaginitis is a very common ailment affecting premenopausal women in Nigeria. This condition is more prevalent in the age group between 21-30 years. More than 75% of premenopausal wom...
The purpose of this study is to determine to what degree Hypocol® (Red Yeast Rice) may lower low density lipoprotein (LDL)-cholesterol in a European population. The effect of Red Yeast Ri...
