摘要

摘要绿藻Prasiola fluviatilis (Sommerfelt) Areschoug ex Lagerstedt生长在寒冷的海洋环境中。该物种主要分布在北极周围，但也有报道称在两个半球低纬度地区的冰川地区。中国在20世纪上半叶曾报道过一次，但由于没有描述、插图或凭证标本，无法证实该记录的身份。本文通过形态特征、生境特征和质体rbcL和tufA基因序列分析，证实了新疆天山地区存在河流假蝇。讨论了河流假单胞虫的生物地理分布及其与其他陆生和淡水假单胞虫的系统发育关系。

Morphological and Phylogenetic Data Confirm the Identity of Prasiola fluviatilis (Prasiolales, Trebouxiophyceae) from Glacier Streams in the Tianshan Mountains, China

ABSTRACT The green alga Prasiola fluviatilis (Sommerfelt) Areschoug ex Lagerstedt occurs in cold lotic environments. The species has a mainly circumarctic distribution, but has also been reported from glacier areas in lower latitude regions in both hemispheres. It was reported from China on a single occasion in the first half of the 20th century, but without description, illustrations or voucher specimens the identity of this record cannot be verified. Here we confirm the presence of P. fluviatilis in the Tianshan Mountains, Xinjiang Province, China based on morphological features, habitat characteristics, and plastid rbcL and tufA gene sequences. The biogeographic distribution of P. fluviatilis and its phylogenetic relationship with other terrestrial and freshwater Prasiola species are discussed.
