Abstract

Abstract: Chlorophyll b -containing, phycobiliprotein-less cyanobacterium (“prochlorophyte”) Prochlorothrix scandica Skulberg 2008 represents the second species of the genus Prochlo-rothrix . Distinction between the strains P. scandica NIVA-8/90 and Prochlorothrix hollandica PCC 9006 (CCAP 1490/1 T ) is based predominantly on genomic DNA properties. The degree of DNA reassociation of the two strains is 5 %. Compared to P. hollandica, P. scandica possesses an additional rrn operon. In addition, there is a distinct polymorphism of the highly iterated short palindromes (Hip1). Among the pheno-typic features different in the two species are cell morphology, growth temperature optimum and fatty acids content. Keywords: polyphasic taxonomy, prochlorophytes, cyanobacteria, ITS, Hip1, Prochlorothrix, Prochlorothrix scandica The GenBank accession number for the single 16S−23S ITS sequence of Prochlo-rothrix hollandica PCC 9006 T is HQ316172 and the accession numbers for the two 16S−23S ITS sequences of

丝状原叶藻原绿思(Prochlorothrix scandica Skulberg)的多相修正描述2008

摘要/ Abstract摘要:含叶绿素b、不含藻胆蛋白的蓝藻原绿菌(Prochlorothrix scandica Skulberg 2008)是原绿菌属的第二种。菌株P. scandica NIVA-8/90和原荷兰绿思菌PCC 9006 (ccap1490 /1 T)之间的区别主要基于基因组DNA特性。两个菌株的DNA重关联度为5%。与荷兰假单胞菌相比，斯堪的纳维亚假单胞菌拥有一个额外的rrn操纵子。此外，高迭代短回文(Hip1)具有明显的多态性。在表型特征中，两种植物的细胞形态、最适生长温度和脂肪酸含量不同。关键词:多相分类，原绿藻，蓝藻，ITS, Hip1，原绿thrix, scandica原绿thrix。Prochlo-rothrix hollandica PCC 9006 T的单个16S−23S ITS序列的GenBank登录号为HQ316172, Prochlo-rothrix PCC 9006 T的两个16S−23S ITS序列的登录号为
