Yellow-band disease (similar to Yellow Blotch disease)〔(Yellow-blotch/Yellow-band Disease )〕 is a disease that attacks colonies of coral at a time when coral is already under stress from pollution, overfishing, and climate change.〔 (【引用サイトリンク】title=yellow band disease News - insciences ) 〕 It is characterized by large blotches or patches of bleached, yellowed tissue on Caribbean scleractinian corals.〔 (【引用サイトリンク】title=Common Identified Coral Diseases ) 〕 Yellow-band disease is a bacterial infection that spreads over coral, causing the discolored bands of pale-yellow or white lesions along the surface of an infected coral colony. The lesions are the locations where the bacteria have killed the coral’s symbiotic photosynthetic algae, called zooxanthellae which are a major energy source for the coral.〔 (【引用サイトリンク】title=NOAA National Ocean Service Education: Example of yellow band disease ) 〕 This cellular damage and the loss of its major energy source cause the coral to starve, and usually cause coral death. There is evidence that climate change could be worsening the disease.〔 〕 ==Mechanism of action== Coral provides a stable environment for marine organism which is destroyed by Yellow-band disease (or yellow blotch disease). The bacteria produces the characteristic pale yellow lesions and eventually kills the zooxanthellae by impairing its mitosis and its ability to carry out photosynthesis. Yellow-band disease is found on coral reefs in the Caribbean.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yellow-band disease」の詳細全文を読む スポンサード リンク
