Native DNA repeats and methylation in Ascobolus.
We identified two classes of native dispersed DNA repeats in the Ascobolus genome. The first class consisted of several kilobase long, methylated repeats. These repeats, named Mars (methylated Ascobolus repeated sequences), fell in one family of LINE-like elements and in three families of LTR-containing retrotransposable elements. The methylation features of Mars elements were those expected if...
متن کاملInterference Competition among Coprophilous Fungi: Production of (+)-Isoepoxydon by Poronia punctata.
(+)-Isoepoxydon has been established as the major causative agent of interference competition between Poronia punctata (NRRL 6457), a late fungal colonist of cattle dung, and two early-occurring dung colonists, Ascobolus furfuraceus (NRRL 6460) and Sordaria fimicola (NRRL 6459). This compound was isolated from ethyl acetate extracts of liquid cultures of P. punctata by silica gel chromatography...
متن کاملSuppression of crossing-over by DNA methylation in Ascobolus.
Homologous recombination between dispersed DNA repeats creates chromosomal rearrangements that are deleterious to the genome. The methylation associated with DNA repeats in many eukaryotes might serve to inhibit homologous recombination and play a role in preserving genome integrity. We have tested the hypothesis that DNA methylation suppresses meiotic recombination in the fungus Ascobolus imme...
متن کاملGene Conversion in the Pasadena Strain of ASCOBOLUS IMMERSUS.
TUDIES on a strain of Ascobotus immersus collected in Pasadena, California ( Y u S U N 1964) have shown unusually high rates of gene conversion at a number of sites of white-spored mutations. In most such examples conversion ratios 5 t : 3w (wild type: white) and especially 3+: 5w have been common. Closely linked sites frequently have had very similar distributions of the different conversion r...
متن کاملUniform PERs and Comportment Analysis
Hunt showed that the notion of PER-based strictness properties subsumed the incomparable notions of idealand projection-based properties on non-lifted value spaces. We extend Hunt’s idea so it can encompass other comportment properties (such as totality) by separating the information and fixpoint orderings. We then define a class of uniform PERs (in the sense that they treat non-bottom ground e...
