Diversity of epiphytic bacterial communities on male and female Porphyra haitanensis

Abstract Purpose To study the structure of epiphytic bacterial community male and female Porphyra haitanensis , in order to explore similarities differences between dioecious macroalgae . Methods Collection from intertidal zone Niushan Island, Fujian, China. Epiphytic bacteria were collected studied, composition diversity explored using high-throughput sequencing technology. Results There was no significant difference on ?-diversity ?-diversity. Proteobacteria Bacteroidetes core microbiota Bacteria Maribacter (male 14.87%, 1.66%) Tenacibaculum 1.44%, 25.78%) most indicative taxa Conclusions Sex have some influence construction communities but they are not decisive factors affecting
