The Booroola fecundity gene (FecB) increases ovulation rate and litter size in sheep is inherited as a single autosomal locus. effect of FecB additive for (increasing by about 1.6 corpora lutea per cycle each copy) has been mapped to chromosome 6q23–31, which syntenic human 4q21–25. Bone morphogenetic protein IB (BMP-IB) receptor (also known ALK-6), binds members the transforming growth factor-β (TGF-β) superfamily, located region containing have mutation (Q249R) highly conserved...
Recent discoveries that high prolificacy in sheep carrying the Booroola gene (FecB) is result of a mutation BMPIB receptor and Inverdale (FecXI) BMP15 oocyte-derived growth factor have allowed direct marker tests to be developed for FecB FecXI. These were carried out seven strains (Javanese, Thoka, Woodlands, Olkuska, Lacaune, Belclare, Cambridge) which inheritance patterns suggested presence major genes affecting prolific Garole India, been proposed as ancestor Australian Merinos. The was...

It was established that Candida albicans grew rapidly in a simple medium containing yeast extract (0·2 %, w/v) plus glucose (2 w/v). These cultures were or near to state of nitrogen limitation and the concentration secreted aspartate proteinase increased (within 3–4 h) on addition BSA. Synthesis secretion apparently controlled both positively (induction by albumin or, more probably, peptides produced from it) negatively (repression NH4Cl). A small intracellular pool enzyme detected during...
The intraovarian roles of BMP family members such as BMP2, 4, 6 and 7 are not well understood, particularly in species with low ovulation rates sheep. Therefore, the objectives these experiments were to determine expression patterns mRNAs encoding during ovarian follicular development sheep, effects growth factors on ovine granulosa cell functions vitro. For comparative purposes, BMPs also determined rat cells since have been most widely studied this poly-ovulatory species. As assessed by...
The redox structure of the water column in anoxic basins through geological time remains poorly resolved despite its importance to biological evolution/extinction and biogeochemical cycling. Here, we provide a temporal record bottom pore conditions by analyzing distribution chemistry sedimentary pyrite. We combine machine-reading techniques, applied over large library published literature, with statistical analysis element concentrations databases pyrite bulk rocks generate scaled spanning...
(1973). The Stemonitomycetidae, A New Subclass of Myxomycetes. Mycologia: Vol. 65, No. 2, pp. 477-485.
Certain strains of Myxomycetes grown in pure culture liquid media display widely varying chromosome numbers which indicate the presence polyploid series amoebae and plasmodia. The implications these number variations on existing controversies concerning Myxomycete life cycles cytology are discussed.

Illus. 1960.–Three discoideum having the number chromosomes (14) at all stages their life cycle were examined. No evidence sexuality as shown by syngamy or meiosis was found in strains. Two unstable and reverted to haploid type with 7 chromosomes. These had a sexual phase which observed. The nuclear behavior both differed from that reported previous papers.
Basal bodies and centrioles are conserved microtubule-based organelles whose improper assembly leads to a number of diseases, including ciliopathies cancer. Tubulin family members components these structures that integral their proper formation function. We have identified the ε-tubulin gene in Tetrahymena thermophila localized protein through fluorescence tagged allele basal bodies. Immuno-electron microscopy has shown localizes primarily core microtubule scaffold. A complete genomic...

Eighteen field-collected isolates of Agaricus bisporus from coastal central California and two extralimital field were subjected to allozyme analysis via PAGE, genotypically scored at six polymorphic loci. This population sample carries previously unreported alleles three five loci for which a large culture collection (PSUMCC), composed primarily cultivar lines, had been screened. Only one allele known the PSUMCC was not found in wild population. Novel combinations also found. With...
The mycelium of the basidiomycete Coprinus congregatus is not uniformly competent to differentiate. Differentiation occurs only in localized areas young mycelia. Studies on laccase activities from whole extracts suggest a correlation between overall levels and development mushroom primordia. However, studies higher resolution developmental competence, under variety light, nutrient temperature regimes, indicate that probably involved actual If C. differentiation, it at initial, light-requiring, step.

SUMMARYThe development of the capillitia Stemonitis, Comatricha, and Lamproderma is discussed. In all three genera hypothallus formed underneath fruiting plasmodium. Comatricha stalk composed an interlaced system tubes, some which bend out at intervals to form lateral capillitial threads. The ends these threads remain free. capillitium derived primarily from tubes originating columella. Stemonitis a single large tube, with no individual in arises apex columella free peripheral cytoplasm....
The isolation and successful two‐membered culture of the homothallic myxomycete Perichaena vermicularis (order Trichiales) is reported for first time. Comparisons mitosis in amoebae, zygotes plasmodia as seen with phase contrast microscopy are made distinguishing features different kinds nuclear behavior discussed.
