and : Two New Oomycete Species from Rice Paddies in Iran.

An investigation into oomycete diversity in rice paddies of Fars Province in Iran led to the identification of two new () species as and The identification was based on morphological and physiological features as well as on the phylogenetic analysis of nuclear (ITS and ) and mitochondrial (1 and 2) loci using Bayesian inference and Maximum Likelihood. The present paper formally describes these two new species and defines their phylogenetic relationships with other congeneric species. According to multiple gene genealogy analysis, was grouped with other species of (formerly, clade G of ) and was closely related to both and the recently described The second species, designated , was grouped with other species of (formerly, clade B of ) and, according to the phylogenetic analysis, shared an ancestor with The production of globose hyphal swellings was a major characteristic of , which did not produce vesicles and zoospores.

and Species Associated with Rot of and Other Succulent Plants.

Infections by and -like species on cacti and other succulent plants cause the syndrome known as Fusarium dry rot and soft rot. There are only few records of species as pathogens of cacti and other succulent plants from Iran. The objective of this study was the identification and characterization of fusarioid species recovered from ornamental succulents in Shiraz County, Iran.

Three new Pythium species from rice paddy fields.

In an investigation of the oomyceteous flora in rice paddy fields of Fars Province, Iran, three new Pythium species were isolated and identified on the basis of morphological features and molecular phylogenetic characteristics. Their unique morphological traits, including sexual and asexual structural characteristics (i.e.
