Xisha Islands are located in a low-latitude area that straddles the boundary between the Indian and eastern Asian monsoon systems. The unique and diverse ecosystem provides habitats for numerous microorganisms, generating exceptionally rich microbial resources. Due to the remote geographical locations of most islands and the fact that the coastal vegetation is in the vanguard stage of oligotrophic conditions, the microbial communities may differ from those of islands with complex vegetation. In this study, through the research on the fungal diversity of coastal coral sandy soil in Xisha Islands, two new species of Aspergillus, namely A. paraflavipes and A. ganquanensis, were isolated from the local coral sandy soil samples using potato-dextrose agar. Identifications of new species were carried out based on various methods such as detection of growth rate in plate culture, observation of colony morphology in plate growth, microscopic morphological comparison, and multi-gene combined phylogenetic analysis (ITS-BenA-CaM-RPB2). The results showed that the species exhibiedt taxonomic status and morphological characteristics that are different from those of existing species. By integrating various detection methods and comparison results, they could be regarded as new taxonomic units. A. paraflavipes and A. ganquanensis belonged to the genus Aspergillus, subgen. Circumdati in sect. Flavipedes and sect. Circumdati, respectively. According to the results of the combined phylogenetic analysis of multiple genes, A. paraflavipes in sect. Flavipedes was a separate lineage parallel to the ser. Flavipedes. According to its microscopic morphological structure, it is shown that the conidiomata of A. paraflavipes was very special, and the size of its stipes and vesicles was much smaller than that of other species in the sect. Flavipedes. According to the growth rate detection results, A. paraflavipes could grow at a relatively fast rate (21-24 mm, 7 days) on Czapek yeast autolysate (CYA) at 40 ℃. Among the ser. Flavipedes similar to A. paraflavipes, only A. ardalensis (growth rate ≤2 mm, 7 days) and A. templicola (4-8 mm, 7 days) could grow on CYA at 40 ℃. And its growth rate was extremely slow, and none of the other species grow. Based on the results of phylogenetic analysis, microscopic morphological observation and growth rate comparison, it is believed that A. paraflavipes is located in an undiscovered series in sect. Flavipedes. Therefore, we propose to establish a new strain, ser. Paraflavipedes, to accommodate A. paraflavipes. The detailed morphological comparison and the description of the identification results were described in the article. Multi-gene combined phylogenetic analysis showed A. ganquanensis presented a unique branch in the sect. Circumdati, ser. Sclerotiorum, showing similar morphology to those of the species in this series. This study isolated and documented two new species of Aspergillus originated from the Xisha Islands, expanding our understanding of the fungal diversity of the Xisha Islands. Moreover, it is particularly important to record the biodiversity of the ecosystem before human activities affecting it.

西沙群岛地处低纬度地区,位于印度季风和亚洲季风的中间地带,其独特而多样的生态系统,为众多微生物提供了栖息地,催生了丰富多样的微生物资源。由于大多数岛屿地理位置偏远且滨海植被处于寡营养的先锋阶段,因此微生物群落可能与植被复杂的岛屿存在差异。通过对西沙群岛滨海土壤的真菌多样性进行研究,从当地的珊瑚土壤样本中分离出2个曲霉属(Aspergillus)真菌新物种,即并黄柄曲霉(A.paraflavipes)和甘泉曲霉(A.ganquanensis)。根据形态学比对和多基因联合(ITS+BenA+CaM+RPB2)系统发育分析表明,这些物种表现出独特的分类地位和形态特征,综合结果可以确认为新的分类单元。并黄柄曲霉和甘泉曲霉分别属于曲霉属下环绕亚属(subgen.Circumdati)的黄柄组(sect.Flavipedes)和环绕组(sect.Circumdati)。根据系统发育分析结果显示,并黄柄曲霉在黄柄组(sect.Flavipedes)中是一个平行于黄柄系(ser.Flavipedes)的单独谱系;并且通过形态学比较,发现其孢梗茎(stipes)和顶囊(vesicle)尺寸远小于该组其他物种;此外,在生长速度方面,与并黄柄曲霉相近的黄柄系中仅有A.ardalensisA.templicola能在40 ℃的察氏酵母培养基(CYA)上生长,且生长速度极为缓慢(生长速度<10 mm,7 d),而A.paraflavipes则能以相对较快的速度(21~24 mm,7 d)生长。综上所述,本研究提出设立一个新系并黄柄系(ser.Paraflavipedes)以容纳并黄柄曲霉,详细的形态学比对以及鉴定结果描述在文中阐述。多基因联合系统发育分析显示甘泉曲霉在环绕组(sect.Circumdati)的菌核系(ser.Sclerotiorum)中呈现独特分支,且形态结构与该系中的物种相似。本研究分离并记录了2个源于西沙群岛的曲霉属真菌,拓展了对西沙群岛的真菌多样性认知,并且在人类活动影响该生态系统之前,记录其生物多样性的工作尤为重要。

西沙群岛地处低纬度地区,位于印度季风和亚洲季风的中间地带,其独特而多样的生态系统,为众多微生物提供了栖息地,催生了丰富多样的微生物资源。由于大多数岛屿地理位置偏远且滨海植被处于寡营养的先锋阶段,因此微生物群落可能与植被复杂的岛屿存在差异。通过对西沙群岛滨海土壤的真菌多样性进行研究,从当地的珊瑚土壤样本中分离出2个曲霉属(Aspergillus)真菌新物种,即并黄柄曲霉(A.paraflavipes)和甘泉曲霉(A.ganquanensis)。根据形态学比对和多基因联合(ITS+BenA+CaM+RPB2)系统发育分析表明,这些物种表现出独特的分类地位和形态特征,综合结果可以确认为新的分类单元。并黄柄曲霉和甘泉曲霉分别属于曲霉属下环绕亚属(subgen.Circumdati)的黄柄组(sect.Flavipedes)和环绕组(sect.Circumdati)。根据系统发育分析结果显示,并黄柄曲霉在黄柄组(sect.Flavipedes)中是一个平行于黄柄系(ser.Flavipedes)的单独谱系;并且通过形态学比较,发现其孢梗茎(stipes)和顶囊(vesicle)尺寸远小于该组其他物种;此外,在生长速度方面,与并黄柄曲霉相近的黄柄系中仅有A.ardalensisA.templicola能在40 ℃的察氏酵母培养基(CYA)上生长,且生长速度极为缓慢(生长速度<10 mm,7 d),而A.paraflavipes则能以相对较快的速度(21~24 mm,7 d)生长。综上所述,本研究提出设立一个新系并黄柄系(ser.Paraflavipedes)以容纳并黄柄曲霉,详细的形态学比对以及鉴定结果描述在文中阐述。多基因联合系统发育分析显示甘泉曲霉在环绕组(sect.Circumdati)的菌核系(ser.Sclerotiorum)中呈现独特分支,且形态结构与该系中的物种相似。本研究分离并记录了2个源于西沙群岛的曲霉属真菌,拓展了对西沙群岛的真菌多样性认知,并且在人类活动影响该生态系统之前,记录其生物多样性的工作尤为重要。

Xisha Islands are located in a low-latitude area that straddles the boundary between the Indian and eastern Asian monsoon systems. The unique and diverse ecosystem provides habitats for numerous microorganisms, generating exceptionally rich microbial resources. Due to the remote geographical locations of most islands and the fact that the coastal vegetation is in the vanguard stage of oligotrophic conditions, the microbial communities may differ from those of islands with complex vegetation. In this study, through the research on the fungal diversity of coastal coral sandy soil in Xisha Islands, two new species of Aspergillus, namely A. paraflavipes and A. ganquanensis, were isolated from the local coral sandy soil samples using potato-dextrose agar. Identifications of new species were carried out based on various methods such as detection of growth rate in plate culture, observation of colony morphology in plate growth, microscopic morphological comparison, and multi-gene combined phylogenetic analysis (ITS-BenA-CaM-RPB2). The results showed that the species exhibiedt taxonomic status and morphological characteristics that are different from those of existing species. By integrating various detection methods and comparison results, they could be regarded as new taxonomic units. A. paraflavipes and A. ganquanensis belonged to the genus Aspergillus, subgen. Circumdati in sect. Flavipedes and sect. Circumdati, respectively. According to the results of the combined phylogenetic analysis of multiple genes, A. paraflavipes in sect. Flavipedes was a separate lineage parallel to the ser. Flavipedes. According to its microscopic morphological structure, it is shown that the conidiomata of A. paraflavipes was very special, and the size of its stipes and vesicles was much smaller than that of other species in the sect. Flavipedes. According to the growth rate detection results, A. paraflavipes could grow at a relatively fast rate (21-24 mm, 7 days) on Czapek yeast autolysate (CYA) at 40 ℃. Among the ser. Flavipedes similar to A. paraflavipes, only A. ardalensis (growth rate ≤2 mm, 7 days) and A. templicola (4-8 mm, 7 days) could grow on CYA at 40 ℃. And its growth rate was extremely slow, and none of the other species grow. Based on the results of phylogenetic analysis, microscopic morphological observation and growth rate comparison, it is believed that A. paraflavipes is located in an undiscovered series in sect. Flavipedes. Therefore, we propose to establish a new strain, ser. Paraflavipedes, to accommodate A. paraflavipes. The detailed morphological comparison and the description of the identification results were described in the article. Multi-gene combined phylogenetic analysis showed A. ganquanensis presented a unique branch in the sect. Circumdati, ser. Sclerotiorum, showing similar morphology to those of the species in this series. This study isolated and documented two new species of Aspergillus originated from the Xisha Islands, expanding our understanding of the fungal diversity of the Xisha Islands. Moreover, it is particularly important to record the biodiversity of the ecosystem before human activities affecting it.
