 Abstract

The objective of this study is to investigate the endophytic bacterial communities in Noni (Morinda citrifolia L.) seeds. By using high-throughput sequencing (HTS) technique, a research on the diversity of endophytic bacterial communities in Noni seed samples was conducted by this paper, which were collected from four planting locations in the introduction and cultivation base of Hainan Noni Biological Engineering Development Co., Ltd. in Sanya. A total of 268159 sequences and 2870 Operational Taxonomic Units (OTUs) were obtained from the seed samples, which were classified into N1, N2, N3 and N4, through HTS by bioinformatics analysis. The results showed that there was a good consistency between bacterial community structure and distribution of dominant genus in all samples. A mount of 10 OTUs of the most abundance associated with the four sample libraries were found to be related to Pelomonas sp., Ochrobactrum intermedium, Kinneretia sp., Serratia sp., Paucibacter sp., Leptothrix sp., Inhella sp., Ewingella sp., Thiomonas sp. and Massilia sp.. This study has laid a solid foundation for further study in beneficial microbes, which would help to improve the growth and efficacy of component production in Noni plants.
