The oomycete Pythium periplocum is an aggressive mycoparasite of a number of plant pathogenic fungi and oomycetes and therefore has potential as a biological control agent. Here, we report the first draft genome sequence of P. periplocum, which comprises 35.89 Mb. It contains 1,043 scaffolds and 14,399 predicted protein-coding genes.

While most commonly associated with prokaryotes, horizontal gene transfer (HGT) can also have a significant influence on the evolution of microscopic eukaryotes. Systematic analysis of HGT in the genomes of the oomycetes, filamentous eukaryotic microorganisms in the Stramenopiles-Alveolates-Rhizaria (SAR) supergroup, has to date focused mainly on intradomain transfer events between oomycetes an...

In order to investigate the oomyceteous flora associated with ornamental trees of Shiraz County (Iran), during 2017–18, rhizosphere soil and plant debris of ornamented trees from various parks and green spaces of Shiraz County (including 11 districts) were sampled. Based on morphological, morphometrical and physiological analyses, three Phytophthora species, namely, Ph. cactorum</e...
