In filamentous fungi however, the frequency of ectopic integration events is rather high and the actual efficiency of homologous recombination depends upon the length of homologous DNA flanking the transformation marker. Recently, d'Enfert and coworkers (Chaveroche et al., 2000) presented a two-step technology for the integration of a bi-functional zeocin-pyrG cassette into a target sequence of interest using an Escherichia coli strain expressing the phage lambda Red functions. In the resulting recombinant cosmids, the selection marker is flanked by fungal DNA sequences longer than 1 kb, which can be used to transform appropriate fungal recipient strains. For selection of fungal transformants, those workers used the A. nidulans pyrG gene encoding orotidine-5'monophosphate decarboxylase, which confers prototrophy in appropriate uridine/uracil auxotrophic recipient strains. Here, we describe the novel bi-functional transformation vector pZHK2, which carries in addition to the zeocin resistance gene the hygromycin B phosphotransferase gene often used as a dominant selectable marker gene in fungal recipient strains. The applicability of the vector is demonstrated by generating a ura3 knock out strain from Sordaria macrospora showing auxotrophy.","PeriodicalId":12490,"journal":{"name":"Fungal Genetics Reports","volume":"363 Pt 3 1","pages":"4-6"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79651234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Newsl. 50:17-19 Neurospora possesses more cell types than are commonly recognized. We have been able to identify 28 morphologically distinct types. Having the cell types clearly defined will be important for genome annotation, describing new mutant phenotypes, and determining sites of gene expression. ____________________________________________________________________________________ Neurospora is a morphologically complex multicellular organism with many more cell types than the unicellular yeast Saccharomyces. Most workers are familiar with mycelia, macroconidia, perithecia, asci, and ascospores, but the diversity of cell types produced by Neurospora may not be fully appreciated. Now that the products of specific genes can be localized using GFP and o ther fluorescent proteins, attention will be focused increasingly on particular cell types that differ in morphology, physiology, or developmental origin. D istinguishing different cell types is also important for genome annotation. For convenience, we need to use the terms ‘cell’ and ‘cell type’ rather loosely to cover both cellular elements such as hyphae and discrete cells such as spores (see discussion by Read, 1994). The basic undifferentiated, totipotent cellular element is the compartmentalized vegetative hypha at the colony periphery (the leader hypha). Certain other cell types are comprised of differentiated hyphae (e.g., fusion hyphae, ascogonia, trichogynes, ascogenous hyphae, asci, paraphyses, and periphyses). At the other extreme are highly differentiated nonhyphal cells such as ascospores, microconidia, and the different wall cells of protoperithecia and perithecia. Twenty-eight morphologically distinct cell types are listed and described below. Designation of protoperithecia and microconidia as vegetative or sexual is arbitrary. Additional types or subtypes will no doubt be revealed.","PeriodicalId":12490,"journal":{"name":"Fungal Genetics Reports","volume":"27 1","pages":"17-19"},"PeriodicalIF":0.0,"publicationDate":"2003-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78834707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Terry W. Hill, Darlene M. Loprete, Jared A, Castagna, and Samuel O. Weems. Department of Biology and Department of Chemistry, Rhodes College, Memphis, TN 38112 USA. Even seasoned workers find it tedious and sometimes frustrating to remove Hülle cells and stray conidia from Aspergillus cleistothecia by rolling them with forceps across an agar surface, particularly when large numbers must be cleaned. It can be even more challenging to teach the skill to others, especially to a whole class of easily discouraged undergraduates, who may be seeing their first high-mag image of forceps tips at the same time as their first view of a cleistothecium. The tips of forceps are sharp and rough, and the hands that wield them often shaky. A peridium is no match for an ill-aimed poke or slash. We find, however, that cleistothecia can be cleaned very rapidly, with reduced breakage, and with minimal contamination by doing away with forceps altogether and using instead the tools that nature gave us “at our fingertips”. Indeed they are our fingertips themselves. The method is simply to roll cleistothecia briefly and firmly around the surface of a 4% agar plate (with or without diatomaceous earth per Kaminskyj and Hamer, 1996, Fungal Genetics Newsletter 43:71) beneath a well-cleaned fingertip. A few seconds’ rubbing in a circle about an inch in diameter is all that is required. The pressure of the finger is spread evenly, and the cleistothecia only rarely break. For increased efficiency, several cleistothecia can be rubbed at once beneath a single fingertip. Soap-andwater washing, followed by two or three 10-second immersions of the finger in 95% alcohol, with Kimwipe-drying after each immersion, is sufficient in our experience to reduce levels of bacterial contamination to no more than those observed when using flamed forceps – i.e., essentially none.

Metzenberg. Visiting Prof., Dept. of Chemistry and Biochemistry, University of California, Los Angeles CA 90095. Fungal Genet. News. 50:14 Vogel's Medium N salts (Vogel, 1956 Microbiol. Genet. Bull. 13:42-43), supplemented with a carbon source, is widely used for the cultivation of Neurospora and many other fungi. The standard recipe includes ammonium nitrate. Because the ammonium ion is a reductant and nitrate ion is an oxidant, solid ammonium nitrate is potentially an explosive, as is well known from the disastrous 1947 Texas City accident and from more recent acts of terrorism such as the bombing of the Federal Building in Oklahoma City. Ammonium nitrate can explode without being deliberately detonated. Shipping it, therefore, presents some problems, and even declaring it in a lab inventory may do so in the future. The tendency of the dry salt to become caked in its container invites foolish actions to free up a sample, for example, banging the jar on the edge of a benchtop . The following recipe yields an identical final composition to Vogel's Medium N, but employs potassium nitrate and ammonium phosphate. Since potassium ion is not a reductant and phosphate ion is not an oxidant, the dry ingredients can be regarded as harmless, as, of course, are the dissolved salts. The following recipe is for 1 liter of 50X salts. water 750 ml. Na3 citrate .2H2O 130 g. KNO3 126 g. (NH4)H2PO4 144 g. KH2 PO4 80 g. MgSO4 7 H2O 10 g.
