A taxonomic summary and revision of Rozella (Cryptomycota)

Morphological, molecular, and ultrastructural characterization of Rozella rhizoclosmatii, a new species in Cryptomycota.

Rozella is a genus of unwalled endoparasites of a variety of hosts including Oomycota (Stramenopiles), Blastocladiomycota and Chytridiomycota (Fungi), and one green alga (Coleochaete, Chlorophyceae). It currently includes more than 20 formally described species, and no new species of Rozella have been described since 1987. We discovered a new Rozella species parasitizing Rhizoclosmatium globosu...

Ultrastructural characterization of the host-parasite interface between Allomyces anomalus (Blastocladiomycota) and Rozella allomycis (Cryptomycota).

Rozella allomycis is an obligate endoparasite of the water mold Allomyces and a member of a clade (= Opisthosporidia) sister to the traditional Fungi. Gaining insights into Rozella's development as a phylogenetically pivotal endoparasite can aid our understanding of structural adaptations and evolution of the Opisthosporidia clade, especially within the context of genomic information. The purpo...

TAXONOMIC REVISION OF THE CYPERUS SUBGENUS CYPERUS IN IRAN

The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...

A TAXONOMIC REVISION OF THE GENERA STERIGMOSTEMUM AND PETINIOTIA IN IRAN

The genus Sterigmostemum M. Bieb. belongs to the tribe Hesperideae of the Brassicaceae family. The results of this research confirmed the recognition of five species in Iran: S.incanum, S. sulphureum,  S. ramosissimum,  S. acanthocarpum  and S. longistylum. S. laevicaule is excluded from the genus Sterigmostemum and is regarded as a synonym of Erysimum crassicaule. The new combination, namely, ...
