Abstract:
... Two Pyrenopeziza species, P. protrusa and P. nervicola known to have similar morphology, were newly reported from Japan. This study clarified that P. protrusa morphologically differs from P. nervicola in (1) more protruded outermost cells in ectal excipulum, (2) smaller ascospores, and (3) longer and thinner asci. Pyrenopeziza protrusa produces chlamydospore-like brown cells under culture while P. ...

Abstract:
... Genus Apanteles is a cosmopolitan and largest genus in Microgastrinae that can be set as chief example of the subfamily to be studied for. However, highly similar morphological characters intraspecifically lead to difficulty in identifying this genus. In this study, 25 individuals of Apanteles were identified morphologically and molecularly by using error rates approach of barcoding analysis. The ...

Abstract:
... Ribosomal DNA, the topic of this special issue, has long fascinated biologists. The RNA products of the ribosomal DNA are the ribosomal RNAs that are part of the ribosome. In this special issue, we focus on the sequence, molecular organization, repair, stability, copy number, and peculiar genetics of this region of the genome. The locus can impact not only the translational capability of cells, bu ...

Abstract:
... Our goal is to draw a line—hypothetical in its totality but experimentally supported at each individual step—connecting the ribosomal DNA and the phenomenon of transgenerational epigenetic inheritance of induced phenotypes. The reasonableness of this hypothesis is offset by its implication, that many (or most) (or all) of the cases of induced-and-inherited phenotypes that are seen to persist for g ...

As many fungal species cannot be cultured, morphological identification of those species is almost impossible. But, DNA barcoding technique can be employed for identification of such species. For fungal taxonomy prediction, the ITS (internal transcribed spacer) region of rDNA (ribosomal DNA) is used ...

Abstract:
... The systematic position of Urotrema Braun, 1900 and the family Urotrematidae Poche, 1926 have always been controversial. Due to its unusual morphological characteristics, lack of knowledge of the life cycle or details of its excretory system, this family was placed within different higher taxonomic groups of digeneans. Despite being one of the most enigmatic digenean families in terms of its phylo ...
