温泉红藻学名:Cyanidiophyceae)是一群生活在高温高酸环境中的单细胞红藻[1],主要分布于世界各地火山活动仍然活跃,并具有硫酸成分高之温泉水体之地区,如美国黄石国家公园、意大利火山区、新西兰火山区、印尼火山区及日本火山区[2]。根据目前的分类系统,温泉红藻目前主要有四属九种(Cyanidium caldarium, Cyanidium chilensis, Cyanidioschyzon merolae, Cyanidiococcus yangmingshanensis, Galdieria sulphuraria, Galdieria daedala, Galdieria partita, Galdieria maxima, Galdieria phlegrea)[3]。其中,Cyanidioschyzon merolae细胞核基因组最早被解密[4],也是目前唯一一种真核生物之基因组达到100%的解密[5]。另外,其线粒体叶绿体之基因组也完成解密。因此,对于温泉红藻的研究中,Cyanidioschyzon merolae可说是最佳的模式物种。部分藻种能栖息在硫磺口喷气处潮湿之土壤表层,另有些藻种能够存活于具有地热酸性潮湿之岩石表面下,靠着穿透石缝微弱之光线进行光合作用[6]

Cyanidium sp.
科学分类 编辑
门: 红藻门 Rhodophyta
亚门: 小青藻亚门 Cyanidiophytina
纲: 温泉红藻纲 Cyanidiophyceae

In older texts it has been known as "Cyanidales". It was granted phylum status in the Saunders and Hommersand 2004 classification (as "Cyanidophyta"), but demoted to subphylum in the Yoon et al. classification of 2006.[7]
