The new genus name Dolichospermum, for most of the planktonic former members of the genus Anabaena, is one of the most ubiquitous bloom-forming cyanobacterial genera. Its dominance and persistence have increased in recent years, due to eutrophication from anthropogenic activities and global climate change. Blooms of Dolichospermum species, with their production of secondary metabolites that commonly include toxins, present a worldwide threat to environmental and public health. In this review, recent advances of the genus Dolichospermum are summarized, including taxonomy, genetics, bloom occurrence, and production of toxin and taste-and-odor compounds. The recent and continuing acquisition of genome sequences is ushering in new methods for monitoring and understanding the factors regulating bloom dynamics.
新属名 Dolichospermum，是大多数浮游性前蓝藻属 Anabaena 成员的名称，是最普遍的形成水华的蓝细菌属之一。由于人为活动和全球气候变化导致的富营养化，其优势和持久性近年来有所增加。含有毒素等次生代谢产物的 Dolichospermum 物种水华的爆发，对环境和公共健康构成了全球性威胁。在这篇综述中，总结了 Dolichospermum 属的最新进展，包括分类学、遗传学、水华发生以及毒素和异味化合物的产生。最近和持续获得的基因组序列为监测和了解调节水华动态的因素带来了新的方法。
