从叠层石中纯化得到一株含叶绿素丝状蓝藻，命名为Halomicronema hongdechloris gen., sp.。十一月其系统发育分类和形态特征。 Hongdeloris 含有四种主要的类胡萝卜素和两种叶绿素，a 和 f。 Chl f 与 Chla a 的比例可逆地从红光下的 1:8 变为白光培养条件下无法检测到的 Chl f 水平。在白光生长条件下诱导藻胆蛋白。 748 nm 的荧光发射峰被确定为 Chl f 所致。结果表明 Chl f 是一种红光诱导叶绿素。 (C) 2012 年欧洲生化学会联合会。由 Elsevier B.V. 出版。保留所有权利。
A Chl f-containing filamentous cyanobacterium was purified from stromatolites and named as Halomicronema hongdechloris gen., sp. nov. after its phylogenetic classification and the morphological characteristics. Hongdechloris contains four main carotenoids and two chlorophylls, a and f. The ratio of Chl f to Chl a is reversibly changed from 1:8 under red light to an undetectable level of Chl f under white-light culture conditions. Phycobiliproteins were induced under white light growth conditions. A fluorescence emission peak of 748 nm was identified as due to Chl f. The results suggest that Chl f is a red-light inducible chlorophyll. (C) 2012 Federation of European Biochemical Societies. Published by Elsevier B.V. All rights reserved.
