Abstract
Coral reefs are the most magnificent and diverse marine ecosystems on Earth. Coral reefs have had a crucial role in shaping the ecosystems that have dominated tropical oceans over the past 200 million years. Recently major impacts of climate change including, uprising seawater temperature and ocean acidification, might have accelerated the process of destruction on coral reefs worldwide. The Kuroshio Current originates in the northern Philippines, enters the East China Sea through a strait between Taiwan and the Yaeyama Islands, and flows northward to the west of the Ryukyu Islands. In this research, we studied the physiological aspect, and transcriptional responses of the common soft coral in Japan, Korea and Taiwan against the heat stress. We collected corals from 3 sites in Korea, and 2 sites in Taiwan and 2 sites in Japan. The morphological responses of corals to a range of exposure time (6, 12, 24 and 48h) and various temperature (10, 26, 28 and 30 0C). For the microarray experiment we exposed corals to various temperature (26, 28 and 30 0C) for 24h and hybridized those RNAs extracted from the exposed groups with that of control group on the Sgr Oligo chip. As the results, 1979 genes expressions were induced and 2533 genes were reduced over 2-fold in 26 0C group, 2504 genes expressions were induced and 3520 genes were reduced over 2-fold in 28 0C group, 3148 genes expressions were induced and 3676 genes wimate change including, uprising seawater temperature and ocean acidification, might have accelerated the process of destruction on coral reefs worldwide.
