Systematics and phylogeny of Cordyceps and the Clavicipitaceae with emphasis on the evolution of host affiliation

Creator:

Sung, Gi-Ho

Cordyceps is a genus of perithecial ascomycetes. It includes over 400 species that are pathogens of arthropods and parasites of the truffle genus Elaphomyces. Based on the morphology of cylindrical asci, thickened ascus apices and filiform ascospores, it is classified in the Clavicipitaceae (Hypocreales), which also includes endophytes and epiphytes...

Studies on the centromere-specific histone, CenH3, of Neurospora crassa and related ascomycetes

Creator:

Phatale, Pallavi A.

Abstract:

In eukaryotes, the defined loci on each chromosome, the centromeres, accomplish the critical task of correct cell division. In some organisms, centromeres are composed of a euchromatic central core region embedded in a stretch of heterochromatin and the inheritance and maintenance of centromeres are controlled by dynamic epigenetic phenomena. Although...
