The present investigation focused on studying the phylogenetic position of the green endosymbiont, , collected from the Gulf of Mannar, India. In this study, we re-examined the evolutionary position of this endosymbiotic algae using rbcL sequences. The phylogenetic analysis revealed that is distantly related to the species, and formed a monophyletic clade with Marsupiomandaceae. Based on the phylogenetic association of endosymbiont with Maruspiomonadales it was concluded that the endosymbiont belongs to an independent genus within the family Marsupiomonadaceae. At the site of the bloom, was found to exhibit a dense monospecific proliferation, with an average cell density of 27.l88 × 10 cells L. The investigation revealed that the green during its senescent phase primarily relied on autotrophic nutrition, which was confirmed by the presence of a high number of trophonts, vegetatively reproducing cells (1.45 × 10 cells L) and the absence of food vacuoles.

阿拉伯海东南部马纳尔湾夜光藻和绿色夜光藻营养动态的系统发育关系

本研究的重点是研究从印度马纳尔湾收集的绿色内共生体的系统发育位置。在这项研究中，我们使用 rbcL 序列重新研究了这种内共生藻类的进化地位。系统发育分析表明，该物种与该种有远缘关系，与Marsupiomandaceae形成单系支。基于内共生体与 Maruspiomonadales 的系统发育关联，得出结论，内共生体属于 Marsupiomonadaceae 科内的独立属。在开花部位，发现呈现密集的单特异性增殖，平均细胞密度为27.l88 × 10 cells L。调查显示，绿色在衰老阶段主要依靠自养营养，这一点得到了证实存在大量营养体、营养繁殖细胞 (1.45 × 10 个细胞 L) 且不存在食物泡。
