Coral reefs which form some of the most diverse ecosystems on Earth support many symbiotic relationships. Symbiodinium can provide up to 90% of a coral.s energy requirements. Temperature rise, turbid water and high salinity in the Persian Gulf were among the factors separating zooxanthellae from corals and result in bleaching phenomenon. Therefore, it is crucial to identify Symbiodinium of the ...

Reef- building coral harbor communities of photosynthetic taxa of the genus Symbiodinium (zooxanthellae). The genus Symbiodinium is currently classified into nine genetic clades (A–I). Various corals harbor different Symbiodinium clades some show specificity to single strain. Coral and their zooxanthellae are sensitive to environmental stresses. In the Persian Gulf, coral reefs are subject to h...
Pythium is a fungus-like genus with worldwide distribution that is found in most terrestrial and aquatic ecosystems. It is a species-rich genus contains important plant pathogenic species. Little is known on the systematics of Pythium in West Azarbaijan province (N.W. Iran). Thus, the aim of this study was to identify 200 isolates collected from different cultivated soils of West Azarbaijan pro...
Clade D Symbiodinium are thermally tolerant coral endosymbionts that confer resistance to elevated sea surface temperature and bleaching to the host. The union between corals and clade D is thus important to management and coral conservation. Here, we review the diversity and biogeography of clade D Symbiodinium, factors linked to increasing abundances of clade D, and the benefits and drawbacks...
Reef-building corals switch endosymbiotic algae of the genus Symbiodinium during their early growth stages and during bleaching events. Clade C Symbiodinium algae are dominant in corals, although other clades - including A and D - have also been commonly detected in juvenile Acroporid corals. Previous studies have been reported that only molecular data of Symbiodinium clade were identified with...
Taxonomic uncertainty of the Asian tree frog Polypedates leucomystax complex presents the challenging task of inferring its biogeographical history. Here, we describe its dispersion and the genetic relationships among different populations in Thailand, where we connect the population of the P. leucomystax complex of the Sunda Islands to the Indochina (mainland) population based on analyses of 2...

Diversity among global isolates of HIV-1 presents a formidable challenge for vaccine development. As distinct clades of the virus are recognized, it will be important to monitor their geographic distribution and divergence. In this study, we characterized HIV-1 subtypes from 17 seropositive individuals in Nairobi and Mombasa, Kenya. Seventy-one percent of viruses were clade A and 29% were clade...
Reef-building corals harbor symbiotic dinoflagellates, Symbiodinium spp., which are currently divided into several clades. The responses of corals associated with different Symbiodinium clades to thermal stress are not well understood, especially at a gene expression level. Juveniles of the coral Acropora tenuis inoculated with different algal types (clade A or D) were exposed to thermal stress...
