    Notes: Summary We have examined the structure of the rRNA genes from the mitochondrial genome of Podospora anserina. Using R-loop analysis, nuclease protection experiments, and Southern blot hybridization analysis we have observed two intervening sequences (IVS) in the large rRNA gene, and none in the small rRNA gene. the IVS sequences are 1.65 kbp and 2.73 kbp long, and the larger of the two is in the position of the conserved IVS found in the mitochondrial genomes of other fungi. We have detected precursor transcripts for the large rRNA, and these data support the observation of two IVS in this gene. We also note that the large and small rRNA genes are separated by approximately 6 kbp of DNA.

    Transcription of a mitochondrial plasmid during senescence in Podospora anserina (1983)
    Springer

    Topics: Biology
    Notes: Summary In the ascomycete fungus Podospora anserina, cellular senescence is characterized by the excision, circularization, and amplification of specific segments of the non-senescent mitochondrial genome. During senescence, various plasmids can be found in the mitochondria, and different senescent events produce different plasmid populations. In this paper we have examined the transcriptional activity of one mitochondrial plasmid (α-sen DNA) and have contrasted this with the non-senescent mitochondrial genome of rapidly (A+) and slowly (s+) senescing races. In non-senescent and senescent mitochondria we observe two RNAs which are homologous to α-sen DNA and to the parental locus on the native genome. These are 2.4 and 2.5 kb long and have different 5′ ends while overlapping throughout most of their lengths. They may represent different transcripts for α-sen DNA and the parental genome and indicate that excision of the plasmid begins 450 bp from the 5′ end of the genomic coding sequence. Transcription of the α-sen DNA plasmid appears to be active in both senescent and in non-senescent mycelia.

    Notes: [Auszug] The presence in young, non-senescent s race mitochondria of autonomously replicating a-event senDNA has been reported previously7. Because of the obvious interest in examining senescence in terms of both the occurrence of senDNAs and the race-specific timing of senescence, we began to contrast the ...

    Reversible pseudohyphal growth in haploid Saccharomyces cerevisiae is an aerobic process (1993)

    Notes: Abstract Pseudohyphal growth in Saccharomyces cerevisiae has been postulated to be an adaptation to foraging for nitrogen during nitrogen starvation. This process was described as a strictly diploid phenomenon which did not occur in haploid yeast cells and was under the genetic control of both the mating-type locus and a group of five genes, the BUD genes, regulating bud formation. We have also observed a dimorphic growth pattern in yeast growing on various nitrogen-limiting synthetic media. However, and in contrast to a previous report, we find that pseudohyphal growth is not precluded in haploid cells. We demonstrate that haploid pseudohyphal growth is strictly oxygen-dependent and is rapidly reversible, defining pseudohyphal growth as a reversible developmental pathway in yeast.

    Analysis of aldehyde oxidase and xanthine dehydrogenase/oxidase as possible candidate genes for autosomal recessive familial amyotrophic lateral sclerosis (1995)

    Notes: Abstract Recently, point mutations in superoxide dismutase 1 (SOD1) have been shown to lead to a subset of autosomal dominantly inherited familial amyotrophic lateral sclerosis (ALS). These findings have led to the hypothesis that defects in oxygen radical metabolism may be involved in the pathogenesis of ALS. Therefore, we decided to analyze other enzymes involved in oxygen radical metabolism for possible involvement in other forms of ALS. We report here analysis of two genes encoding the molybdenum hydroxylases aldehyde oxidase (AO) and xanthine dehydrogenase/ oxidase (XDH) for involvement in ALS. Of particular interest, one gene identified as encoding aldehyde oxidase is shown to map to 2q33, a region recently shown to contain a gene responsible for a familial form of ALS with autosomal recessive inheritance (FALS-AR). The AO gene appears to be located within 280,000 bp of simple sequence repeat marker D2S116, which shows no recombination with the FALS-AR locus. The AO gene is highly expressed in glial cells of human spinal cord. In addition, we mapped a gene for XDH to 2p22, a region previously shown to contain a highly homologous but different form of XDH. Neither of these XDH genes appears to be highly expressed in human spinal cord. This evidence suggests that AO may be a candidate gene for FALS-AR.

    An auxin-induced polypeptide in dicotyledonous plants (1987)
    Springer
    Plant molecular biology 9 (1987), S. 625-634

    ISSN: 1573-5028
    Keywords: auxin ; auxin-inducible protein ; protein blots
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Antisera were raised to a 70-kD (kilodalton) soybean (Glycine max) protein encoded by a 2,4-dichlorophenoxyacetic acid (2,4-D) inducible mRNA, GH3. These antisera have been used to probe protein blots to study the kinetics and specificity of the GH3 induction response as well as the species specificity and intracellular location of the protein. Detectable levels of the GH3 protein are induced by 2,4-D within 2 h in elongating hypocotyl sections, root sections, and etiolated plumules, and within 30–60 min in soybean suspension cells. Synthesis of the GH3 protein is induced by a variety of auxins. Other plant hormones such as gibberellic acid, cytokinin and ethylene added with or whithout 2,4-D do not alter the level of GH3 protein induction. The GH3 protein is found only in the S100 fraction and is not associated with the nucleus or cell wall. This antiserum also reacts with a 2,4-D-inducible 70-kD protein in other dicots.

    Mitochondrial DNA from Podospora anserina (1982)

    Notes: Summary EcoRI fragments of the 94 kilobase mitochondrial DNA (mtDNA) from young, wild type Podospora anserina were cloned into the EcoRI site of the E. coli plasmid vector pBR325. A complete EcoRI clone bank was developed, containing all 16 of the EcoRI fragments from the native mtDNA. Restriction endonuclease maps for the enzymes SalI, XhoI, BamHI, EcoRI, BglII, and HaeIII were constructed from the analysis of single, double, and triple restriction digests of cloned and native mtDNA. In constructing the maps data were refined by extensive Southern analysis of the native genome hybridized to cloned DNA probes. Restriction maps were analyzed and permitted us to locate the origin of mtDNA derived from senescent cultures. Both the large and small rRNA genes were then localized on these restriction maps using Southern and Northern blot analysis. We have shown the large rRNA locus to lie within a 10.8 kb region of EcoRI fragments E5 and E7, and the small rRNA locus to lie on a 5 kb subfragment of EcoRI fragment E1. The limit of separation between these two loci was determined to be between 6 and 9 kb. Surprisingly, when electrophoresed in agarose-CH3HgOH gels, the large rRNA was found to be 3.8 kb long, 500 bases longer than that from the very closely related Neurospora crassa, making it the largest rRNA yet described.
