采用形态分析和分子分析相结合的方法,对东南亚热带海域褐藻属Padina(Dictyotales,Phaeophyceae)的分类、物种多样性和地理分布进行了研究。这项研究提出了一种新的示意图,显示了一套形态特征,包括对该属物种描述有用的叶状体发际线结构。这项研究还发现了缅甸的两个新种--细柄拟青霉。11月和P.拉提包。11月根据分子和形态数据,细柄假单胞菌的特征是2层叶状体,菌体两面都有细长的毛发,两面距离相等,非工业性生殖毛非常接近下表面的毛发,存在Vauganilastag.lata的特征是2-4层微小的叶状体,只在下表面有宽阔的毛发,非内生生殖毛邻接下表面的毛发并在上表面不规则地展开,以及VauganilaStage的存在。本研究还发现了四个Padinas种的新分布记录:来自缅甸的P.okinwasis和P.Fasciata,P.ryukyana.和P.来自菲律宾的三色。这些发现表明,印度-太平洋中部水域的物种多样性有所增加。这项研究证实,太平洋地区的大多数Padinas物种在各地区呈现重叠分布,而印度洋的物种往往局限于特定地区。
Taxonomy, species diversity, and geographical distribution of the marine brown algal genusPadina(Dictyotales, Phaeophyceae) from tropical South-East Asian waters were investigated through a combination of morphological and molecular analyses. The study presents a new schematic diagram showing a suite of morphological characters including thallus hairline structures that are useful for species delineation in the genus. This study also revealed two new species from Myanmar,P. gracilissp. nov. andP. latasp. nov. based on molecular and morphological data.P. gracilisis characterised by a 2-layered thallus, thin hairlines on both surfaces of the thallus at equal distances, non-indusiate reproductive sori distally very close to the hairlines on the inferior surface, and the presence ofVaughaniellastage.P. latais characterized by a 2–4-layered tiny thallus, broad hairlines located only on the inferior thallus surface, non-indusiate reproductive sori abutting the hairlines on the inferior surface and irregularly spreading on the superior surface, and the presence ofVaughaniellastage. This study also revealed new distributional records for fourPadinaspecies:P. okinawaensisfrom Myanmar andP. fasciata, P. ryukyuanaandP. terricolorfrom the Philippines. These findings point to elevated species diversity in central Indo-Pacific waters. This study confirmed that most of thePadinaspecies in the Pacific regions are showing overlapping distribution across the regions, in contrast to species from the Indian Ocean, which tend to be confined to specific localities.
