摘要

海草属包括11个世界公认的物种。在印度，该属由单一物种Ruppia maritima代表。然而，最近的研究表明，在印度-太平洋地区报道的R. maritima属于R. brevipedunculata。我们对印度Pulicat湖的Ruppia sp.标本进行了研究，发现它属于R. brevipedunculata。Hartog（2014）基于短花梗等关键形态特征。母体叶绿体成熟酶K （matK）基因和核内转录间隔物（ITS）序列的系统发育分析确定了该标本与先前报道的短柄短叶蒿属同种。

Integrative taxonomy reveals the presence of seagrass Ruppia brevipedunculata in India

The seagrass genus Ruppia comprises eleven accepted species worldwide. In India, the genus is represented by a single species Ruppia maritima. However, recent studies indicated that the reported species of R. maritima in the Indo-Pacific region belongs to R. brevipedunculata. We have examined the specimen of Ruppia sp. from Pulicat Lake, India, and found that it belongs to R. brevipedunculata Shuo Yu & Hartog (2014) based on key morphological characters such as the short peduncle. Phylogenetic analysis of the maternal chloroplast maturase K (matK) gene and nuclear internal transcribed spacer (ITS) sequence ascertained the species identity as the specimen clustered with previously reported R. brevipedunculata.

期刊介绍： Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
