Similarities and spatial variations of bacterial and fungal communities in field rice planthopper (Hemiptera: Delphacidae) populations.

摘要: Rice planthoppers are notorious plant sap-feeding pests which cause serious damage. While several microbes in rice have been broadly characterized, the abundance and diversity of bacteria fungi field largely unknown. This study investigated bacterial fungal community compositions Chinese wild Laodelphax striatellus Sogatella furcifera using parallel 16S rRNA gene amplicon internal transcribed space region sequencing. The varied significantly between species were partitioned by sex, tissues host environments each species. majority affiliated with genera Wolbachia, Cardinium, Rickettsia Pantoea. Wolbachia was negatively correlated that Cardinium both planthopper Compared bacteria, did not differ sexes but enriched gut. as a whole showed no significant correlation community. related to Sarocladium, Alternaria, Malassezia, Aspergillus Curvularia. A phylogenetic analysis revealed these closely botanic symbionts or pathogens. Our results provide novel insights into planthoppers.
