The filamentous cyanobacterial genus Moorea gen. nov., described here under the provisions of the International Code of Botanical Nomenclature, is a cosmopolitan pan-tropical group abundant in the marine benthos. Members of the genus Moorea are photosynthetic (containing phycocyanin, phycoerythrin, allophycocyanin and chlorophyll a), but non-diazotrophic (lack heterocysts and nitrogenase reductase genes). The cells (discoid and 25-80 µm wide) are arranged in long filaments (<10 cm in length) and often form extensive mats or blooms in shallow water. The cells are surrounded by thick polysaccharide sheaths covered by a rich diversity of heterotrophic micro-organisms. A distinctive character of this genus is its extraordinarily rich production of bioactive secondary metabolites. This is matched by genomes rich in polyketide synthase and non-ribosomal peptide synthetase biosynthetic genes which are dedicated to secondary metabolism. The encoded natural products are sometimes responsible for harmful algae blooms and, due to morphological resemblance to the genus Lyngbya, this group has often been incorrectly cited in the literature. We here describe two species of the genus Moorea: Moorea producens sp. nov. (type species of the genus) with 3L(T) as the nomenclature type, and Moorea bouillonii comb. nov. with PNG5-198(R) as the nomenclature type.
这里根据《国际植物命名法规》的规定描述了丝状蓝藻属 Moorea gen. nov.，该属广泛分布于热带和全球海洋底层，是一个丰饶的属。Moorea 属的成员是光合作用的（含有藻蓝蛋白、藻红蛋白、别藻蓝蛋白和叶绿素 a），但不是固氮的（缺乏异形胞和氮酶还原酶基因）。细胞（盘状，宽 25-80 µm）排列成长丝状（<10 cm 长），在浅水中常形成广泛的垫或花。细胞被厚多糖鞘包围，上面覆盖着丰富多样的异养微生物。该属的一个独特特征是其具有非常丰富的生物活性次生代谢产物。这与富含聚酮合酶和非核糖体肽合成酶生物合成基因的基因组相匹配，这些基因专门用于次生代谢。编码的天然产物有时是有害藻类大量繁殖的原因，而且由于与 Lyngbya 属形态相似，该属在文献中经常被错误引用。我们在这里描述了 Moorea 属的两个种：Moorea producens sp. nov.（属的模式种），其命名模式为 3L(T)，以及 Moorea bouillonii comb. nov.，其命名模式为 PNG5-198(R)。
