“…These discrepancies might be due to differences in crop types, continuous cropping years, and soil types. It has been reported that the changes in the diversity of soil bacterial community species differed greatly based on different years of continuous cropping [37], and plant species, plant genotypes and soil types had a certain impact on the structure of the soil microbial community [13,[38][39].…”

“…In addition, the content of Lysobacter and Bacillus in the X18 rhizospheric soil were higher than those in Y138. Many studies showed that Bacillus may resist some soil-borne diseases [13,24,34]. The more content of Lysobacter and Bacillus would be more conducive to the growth of X18.…”

“…Soil microorganisms are the key factors related to changes in soil quality, fertility and productivity, and play an important role in ecosystem [10][11][12]. The rhizosphere is the narrow region of soil that surrounds plant roots, where plants, soil, and microorganisms interact dynamically [13]. Rhizospheric soil microorganisms are closely related to the absorption and transformation of soil nutrients.…”

Background: Continuous cropping obstacles from sweet potato are widespread, which seriously reduce the yield and quality, restrict the sustainable development of sweet potato industry. Bacteria are the most abundant in rhizospheric soil and have a certain relationship with continuous cropping obstacles. However, there are few reports on how continuous cropping affected the bacterial community structure in the rhizospheric soil of sweet potato. In this study, high-throughput sequencing technique was used to explore the changes of rhizospheric soil bacterial community structure of different sweet potato varieties, and the correlation between soil characteristics and this bacterial community after continuous cropping, so as to provide a theoretical basis for the prevention and control of sweet potato continuous cropping obstacles.Results: After two years of continuous cropping, the results showed that (1) the dominant bacteria phlya in rhizospheric soils from both Xushu18 and Yizi138 were Proteobacteria, Acidobacteria, and Actinobacteria. The most dominant genus was Subgroup 6_norank. Significant changes in the relative abundance of rhizospheric soil bacteria were observed for two sweet potato varieties. (2) Bacterial richness and diversity indexes of rhizospheric soil from Xushu18 were higher than those from Yizi138 after continuous cropping. Moreover, the beneficial Lysobacter and Bacillus were more prevalent in Xushu18, but Yizi138 contained more harmful Gemmatimonadetes. (3) Soil pH decreased after continuous cropping, and redundancy analysis showed that soil pH was significantly correlated with bacterial community. Spearman’s rank correlations coefficients analysis demonstrated that pH was positively correlated with Planctomycetes and Acidobacteria, and negatively correlated with Actinobacteria and Firmicutes.Conclusions: After continuous cropping of sweet potato, the bacterial community structure and physicochemical properties in the rhizospheric soil were unbalanced, and the changes of different sweet potato varieties were different. The contents of Lysobacter and Bacillus were higher in the sweet potato variety resistant to continuous cropping. It provides a basis for the development of special microbial fertilizer for sweet potatoes to alleviate continuous cropping obstacle.

Fruit rot is one of the most important factors affecting the postharvest quality and shelf life of Lanzhou Lily fruits. The aims of this study were to characterize different isolates from Lanzhou Lily using morphological and molecular approaches and to test their pathogenicity in Lanzhou Lily fruit. Different isolates were collected from decayed Lanzhou Lily fruits in Lanzhou in Gansu Province in China during 2016 and 2017. In total, four isolates were obtained and identified based on their DNA sequences of the 16S rDNA and 26S rDNA genes in combination with the morphological characteristics of the cultures and sporulation. Of the four isolates, one was identified as Bacillus safensis, one was Stenotrophomonas maltophilia and the other two isolates were Metschnikowia pulcherrima. The pathogenicity tests showed that all four isolates were pathogenic in Lanzhou Lily fruit. Previously Fusarium tricinctum has been reported to be the primary cause of fruit rot in Lanzhou Lily throughout the world. Our report is the first to show results that indicate that B. safensis, S. maltophilia and M. pulcherrima are pathogenic in Lanzhou Lily in China. This is the first report on the bacteria and yeast that infect Lanzhou Lily fruits.

Background: Dendrobium is a precious herbal belongs to Orchid and widely used as health care traditional Chinese medicine in Asia. Although orchids are mycorrhizal plants, most researches still focus on endophytes, and there is still large unknown in rhizosphere microorganisms. In order to investigate the rhizosphere microbial community of different Dendrobium species during the maturity stage, we used high-throughput sequencing to analyze microbial community in rhizosphere soil during maturity stage of three kinds of Dendrobium species.Results: In our study, a total of 240,320 sequences and 11,179 OTUs were obtained from these three Dendrobium species. According to the analysis of OTU annotation results, different Dendrobium rhizosphere soil bacteria include 2 kingdoms, 63 phyla, 72 classes, 159 orders, 309 families, 850 genera and 663 species. Among all sequences, the dominant bacterial phyla (relative abundance > 1%) were Proteobacteria, Actinobacteria, Bacteroidetes, Acidobacteria, Firmicutes, Verrucomicrobia, Planctomycetes, Chloroflexi, Gemmatimonadetes. We analyzed the environmental factors of the growth of Dendrobium and found that the environmental factor that affects the rhizosphere soil microorganisms of Dendrobium is the soil factor. Among them, soil factors most closely related to the influence of Dendrobium rhizosphere soil microorganisms include total nitrogen, available phosphorus, ammonium nitrogen and pH value.Conclusions: We found that the rhizosphere bacterial communities of the three kinds of Dendrobium have significant differences, and the main species of rhizosphere microorganisms of Dendrobium are concentrated in the Proteobacteria, Actinobacteria, Bacteroidetes. Moreover, the smaller the level of bacterial, the greater the difference among Dendrobium species. Soil is the most important environmental factor affecting the bacterial communities in the rhizosphere soil of Dendrobium. These results fill the gap in the rhizosphere microbial community of Dendrobium and provide a theoretical basis for the subsequent mining of microbial functions and the study of biological fertilizers.
