Opis:
The genus Phytopythium is a relatively new group of organisms distinguished from the Pythium genus. These are organisms closely related to Pythium and Phytophthora, with similar structure and biology. Despite many similarities, this genus is characterised by several morphological features that allow it to be easily identified. Until now, more than 20 species belong to this genus, most of which are saprophytic organisms. However, there is also a group of species particularly dangerous to plants. These species include, among others, Pp. litorale, Pp. helicoides and Pp. vexans. The purpose of this work was to collect information about these organisms and present them in a condensed form. The study contains basic information about the history of the type of separation, differences in morphology distinctive genus of Phytopythium, Phytophthora and Pythium and information about diseases and host plants. Information is also provided on the potential threat posed by these organisms to forest ecosystems.

Opis:
Phytophthora species are best known as pathogens of agricultural crops (e.g. P. infestans), but there are also invasive pathogens destroying forest atands (e.g. P. ramorum in the USA) or even whole forest ecosystems (e.g. P. cinnamomi in Australia). Still, little is known about indiginous species, especially in wild ecosystems. Rhododendrons are well known as a reservuar for oomycetes’ development. The main objectives of the present study were to develop the new tool for the identification of pathogenic Phytophthora and Phytium based on DNA sequence analysis of the ITS1, 5.8S gene and ITS2 region. Rhododendrons leaves served as specific plant baits. In order to reach the goal the real time PCR, the nested PCR and the DNA sequencing of the rDNA ITS region were carried out. The genomic DNA was extracted form the symptomatic rhododendron leaves. Three distinct Oomycetes species: Phytophthora cactorum, Pythium mercuriale and em>Pythium recalcitrans were detected in rhododendron leaves and registered in GenBank.
