“…Bennett et al (2017a) in their research potentially describe the threats resulting from the presence of these species in mangrove forests (leaf discoloration). Other researchers also found species belonging to this genus in similar conditions (Leanio 2001;Thines 2014;Bennett et al 2017b).…”

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.

An overview on Philippine estuarine oomycetes

Estuarine saprotrophic oomycetes are a group of eukaryotic, fungal-like protists of the Kingdom Straminipila. Species classified as estuarine oomycetes are commonly present on mangrove leaf litter and saltmarsh plant debris. They are distributed over several families (i.e. Peronosporaceae, Pythiaceae, Salisapiliaceae, and Salispinaceae). It is estimated that there are more than 100 species of estuarine oomycetes and, surprisingly, some supposedly terrestrial phytopathogenic hemibiotrophic oomycetes, e.g. Phytophthora elongata, Ph. insolita, and Ph. ramorum, are likewise present in the estuarine biome. In the Philippines, this group has been neglected for several decades as compared to the obligate biotrophic and hemibiotrophic members of Peronosporaceae and Albuginaceae. In this account, a general overview on the systematics and phylogeny of estuarine oomycetes is given. Further, the state of knowledge regarding thallus organization, taxonomy, habitat, and status of Philippine oomycetes are presented.

“…Highest oomycete diversity seems to be in terrestrial plant pathogens (Thines 2009;Thines and Kamoun 2010) such as Phytophthora, Pythium and the downy mildews. Marine oomycetes are commonly from Calycofera, Halophytophthora, Phytopythium, Salisapilia and Salispina (Fell and Master 1980;Ho and Jong 1990;Leaño 2001;Nakagiri 2002;Hulvey et al 2010;Bennett et al 2017aBennett et al ,2017b, where congeners from these group are occurring in marine and brackish water environments, especially in mangroves and colonize submerged leaf litter. Among the initial colonizers of fallen mangrove leaves, Halophytophthora spp.…”

Studies on marine‐sourced fatty acids have gathered significant interest recently as an important component of aquaculture feeds and of biofuel production. Of the organisms capable of producing fatty acids, marine oomycetes are promising model organisms. One group of marine oomycetes are the Halophytophthora spp. which is known to have an important role in leaf decomposition, thereby changing the plant debris into exudates which are usable to consumers in the mangrove ecosystems. This study reports the three mangrove oomycetes isolated from Philippine mangrove forests, identified herein as Halophytophthora vesicula AK1YB2 (Aklan), H. vesicula PQ1YB3 (Quezon) and Salispina spinosa ST1YB3 (Davao del Norte). These isolates were subjected to growth analyses using varying incubation parameters (salinity level and pH), and for fatty acid production. Results revealed the presence of different fatty acids such as Arachidonic acid, Linoleic acid and Vaccenic acid when grown on V8S and PYGS media. This study is the first observation of fatty acids from S. spinosa and H. vesicula from the Philippines. Significance and Impact of the Study Tropical Philippines straddling west of the Pacific Ocean and East of South China Sea is rich in marine and estuarine oomycetes. These micro‐organisms, hitherto poorly known and unstudied in the country, play an important role in the nutritive cycle of the mangrove ecosystem. Due to the increasing demand for an alternative source of fatty acids, species of Oomycetes isolated from select mangrove forests in Luzon, Visayas and Mindanao were analysed for their fatty acid contents. Prospects for industrially‐important fatty acids make these Oomycetes all‐important to study in applied microbiology in the Philippine setting where these structurally simple micro‐organisms abound.
