Abstract

Gayralia brasiliensis Pellizzari, M.C. Oliveira et N.S. Yokoya (Gayraliaceae Ulotrichales), a new record for Indian waters, is described based on morphological, anatomical, and molecular characterization. Gayralia brasiliensis was growing luxuriantly towards the upper limit of the intertidal zone at Shirgaon Creek, Maharashtra, west coast of India. The thalli were pale green in color, growing mat-like on muddy substrata. Juvenile thalli were attached to pneumatophores of mangroves, and barnacles, as well as on polyethylene sheets through a rhizoidal disc. The molecular characterization verifies the presence of G. brasiliensis in western India. We observed overlapping morphological traits between G. brasiliensis and G. oxysperma. However, the ITS sequence showed 100 % similarity with no nucleotide divergence to Brazilian G. brasiliensis. The phylogenetic analysis based on ITS rDNA sequence showed that G. brasiliensis from Shirgaon Creek forms a sister lineage to G. oxysperma.

Gayralia brasiliensis Pellizzari M.C. Oliveira et N.S. Yokoya (Gayraliaceae Ulotrichales)：基于形态和分子分析的印度水域新记录

Gayralia brasiliensis Pellizzari, M.C. Oliveira et N.S. Yokoya（Gayraliaceae Ulotrichales）是根据形态学、解剖学和分子特征描述的印度水域新记录。Gayralia brasiliensis 茂盛地生长在印度西海岸马哈拉施特拉邦 Shirgaon 溪潮间带的上限。藻体呈淡绿色，呈垫状生长在泥质基底上。幼体通过根状盘附着在红树林和藤壶的气生组织以及聚乙烯板上。分子特征验证了 G. brasiliensis 在印度西部的存在。我们观察到 G. brasiliensis 和 G. oxysperma 的形态特征有重叠。然而，ITS 序列显示与巴西 G. brasiliensis 的相似度为 100%，没有核苷酸差异。基于 ITS rDNA 序列的系统发育分析表明，Shirgaon 溪的 G. brasiliensis 与 G. oxysperma 是姊妹系。

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.
