Abstract In marine environments, mutualisms such as those between corals or sea anemones and their algal symbionts (Symbiodiniaceae) play a key role for supporting surrounding biodiversity. However, the breakdown of mutualism and/or Symbiodiniaceae (i.e. bleaching) become increasingly frequent severe, risk losing additional species that rely on them may also increase. While effects anemone blea...
Five previously undescribed triterpenoid saponins (1-5), along with eight known ones (6-13), were isolated from the whole plants of Anemone rivularis var. flore-minore. Their structures were clarified by extensive spectroscopic data and chemical evidence. For the first time, the lupane-type saponins (3 and 12) were reported from the Anemone genus. The anti-proliferative activity of all isolated...
We recently identified the existence of new isoforms of Avt-I (from sea anemone Actineria villosa) and Pstx20 (from sea anemone Phyllodiscus semoni) hemolytic toxins, and named them Avt-II and Pst-I. Avt-II and Pst-I differ in length by 14 and 7 bp, respectively, as compared to their corresponding isoform genes. Both newly found isoform genes have the coding regions with the identical length of...
BACKGROUND Rising sea temperatures are causing significant destruction to coral reef ecosystems due to coral mortality from thermally-induced bleaching (loss of symbiotic algae and/or their photosynthetic pigments). Although bleaching has been intensively studied in corals, little is known about the causes and consequences of bleaching in other tropical symbiotic organisms. METHODOLOGY/PRINCI...
