摘要
利用叶绿体伸长因子 Tu（tufA）和核内部转录间隔标记（ITS）以及大体和显微镜检查，报告了新加坡的一个新科、新属和新种记录--Gayralia brasiliensis（Gayraliaceae, Ulotrichales, Chlorophyta）。由于该物种在当地的分布有限，表面上与更常见的莼菜相似，而且体型较小，因此以前的调查很可能遗漏了该物种。从形态上看，新加坡的 G. brasiliensis 与巴西的 G. oxysperma 更为相似。这项研究表明了分子和形态学综合分析在描述大型藻类多样性特征方面的重要性。
New record of the green macroalga Gayralia brasiliensis (Ulotrichales, Chlorophyta) in Singapore
A new family, genus, and species record, Gayralia brasiliensis (Gayraliaceae, Ulotrichales, Chlorophyta) is reported in Singapore using chloroplast elongation factor Tu (tufA) and nuclear internal transcribed spacer (ITS) markers alongside gross and microscopic examination. This species was likely missed by previous surveys due to its limited local distribution, superficial similarity to the much more common Ulva, and its small size. Morphologically, G. brasiliensis in Singapore is more similar to G. oxysperma than to G. brasiliensis in Brazil. This study demonstrates the importance of integrative molecular and morphological analysis for characterising macroalgal diversity.
期刊介绍：
Botanica Marina publishes high-quality contributions from all of the disciplines of marine botany at all levels of biological organisation from subcellular to ecosystem: chemistry and applications, genomics, physiology and ecology, phylogeny and biogeography. Research involving global or interdisciplinary interest is especially welcome. Applied science papers are appreciated, particularly when they illustrate the application of emerging conceptual issues or promote developing technologies. The journal invites state-of-the art reviews dealing with recent developments in marine botany.
