“…Some species of Aurantimonas have certain antibacterial activity, and researchers have previously isolated an Aurantimonas aggregata sp. nov. in extreme environment (Pereira et al 2017;Li et al 2017). Erwinia amylovora often lead to the fire blight disease, which causes huge economic losses to apples and pears (Borruso et al 2017).…”

Upland rice is an ecotype crop formed by long-term domestication and evolution of rice in the dry land without water layer. Generally, its stem and leaf are thick and luxuriant, its leaf is wide and light, its root system is developed, its root hair is abundant, its osmotic pressure of root and cell juice concentration of leaf are high, and it is drought resistant, heat-resistant and water absorbing. The purpose of this study is to reveal the "core flora" of endophytes in upland rice seeds by studying the diversity and community structure of endophytes in upland rice seeds, and to reveal the impact of soil environment on the formation of endophyte community structure in upland rice seeds by comparing with soil environment microorganisms in upland rice habitats. In this study, the high-throughput sequencing technology based on the Illumina Hiseq 2500 platform was used to study the structure and diversity of endophytic bacterial communities using upland rice varieties collected in different places and soil samples from their unified planting sites as materials. There are 42 endophytic OTUs coexisted in the 14 samples. At the phylum level, the first dominant phyla was Proteobacteria (93.81-99.99%) in all 14 samples. At the genus level, Pantoea (8.77%-87.77%), Pseudomonas (1.15-61.58%), Methylobacterium (0.40-4.64%), Sphingomonas (0.26-3.85%), Microbacterium (0.01-4.67%) and Aurantimonas (0.04-4.34%), which are probably the core microflora in upland rice seeds, served as the dominant genera that coexisted in all upland rice seeds tested. Compared with the soil microbial community structure in the upland rice uniform planting site, it was found that it had little effect on the endophytic community structure in upland rice seeds. This study is of great significance for the isolation, screening, functional evaluation and reaction of some functional microorganisms in upland rice in order to improve its agronomic traits. It also provides a certain reference for the interaction between microorganisms and plants. the adjacent plant tissues. Therefore, endophytes are ubiquitous in the plant host, including the aboveground and underground parts of the plant, even seeds, thus having a positive impact on the plant development (Zinniel et al. 2015; Chebotar et al. 2015). Endophytes can provide a variety of benefits to host plants, especially through multiple functions to improve the growth and health of plants, so that they can be protected from pathogens (Agler et al. 2016; Liu et al. 2017a,b; Xu et al. 2019; Afzal et al. 2019; Sánchez-Cruz et al. 2019). Under different environmental conditions, the communication and interaction between endophyte and plant is stronger than that between rhizosphere bacteria (Coutinho et al. 2015). A number of studies have shown that plant varieties, genotypes and geographical location have a great impact on the establishment of microbial diversity and community structure in plants (Liu et al. 2017a, 2019; Edwards et al. 2015). Although endophyte was discovered more than 100 years ago, its existe...

“…In the present study, spread-plate method was used as parallel complement of culture-independent approach and yielded 629 isolates, which would be helpful to perform more metabolic, physiological and ecological tests in future. Our previous studies have phenotypically, phylogenetically and chemotaxonomically characterized five novel type strains out of the 629 isolates (Li et al, 2017a,b, 2018a,b,c).…”

“…Two gram of each sediment stored at 4°C was measured out with a stainless steel spoon and subsequently resuspended in 20 mL sterile seawater. The suspension were serially diluted and spread on Marine Agar 2216 (MA, BD Difco, MD, USA), MC (Li et al, 2017a,b, 2018a,b,c) and LC (1/100 MC) plates. The suspension plating process was performed in parallel to generate two analogous groups of plates, which were incubated at 4°C for 30 days and at 25°C for 7 days, respectively.…”

The benthic bacterial community in Antarctic continental shelf ecosystems are not well-documented. We collected 13 surface sediments from the Ross Sea, a biological hotspot in high-latitude maritime Antarctica undergoing rapid climate change and possible microflora shift, and aimed to study the diversity, structure and assembly mechanism of benthic bacterial community using both culture-dependent and -independent approaches. High-throughput sequencing of 16S rRNA gene amplicons revealed 370 OTUs distributed in 21 phyla and 284 genera. The bacterial community was dominated by Bacteroidetes, Gamma- and Alphaproteobacteria, and constituted by a compact, conserved and positively-correlated group of anaerobes and other competitive aerobic chemoheterotrophs. Null-model test based on βNTI and RCBray indicated that stochastic processes, including dispersal limitation and undominated fractions, were the main forces driving community assembly. On the other hand, environmental factors, mainly temperature, organic matter and chlorophyll, were significantly correlated with bacterial richness, diversity and community structure. Moreover, metabolic and physiological features of the prokaryotic taxa were mapped to evaluate the adaptive mechanisms and functional composition of the benthic bacterial community. Our study is helpful to understand the structural and functional aspects, as well as the ecological and biogeochemical role of the benthic bacterial community in the Ross Sea.

“…The genus was subsequently emended by Hördt et al [3]. At the time of writing, the genus comprised four recognized species: Aurantimonas coralicida isolated from corals [1], Aurantimonas aggregate isolated from deep-sea sediment [4], Aurantimonas endophytica isolated from plant roots [5] and Aurantimonas manganoxydans isolated from sea water [6]. In this study, we used a polyphasic approach to investigate marine bacterial strain SW136 T , which was found to represent a novel species belonging to the genus Aurantimonas .…”

A novel bacterial strain, designated SW136T, was isolated from a deep-sea sediment sample collected from the South China Sea. Cells were Gram-stain-negative, aerobic, catalase-positive and oxidase-positive. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SW136T represented a novel member of the genus Aurantimonas , forming a distinct cluster with ‘ Aurantimonas litoralis ’, Aurantimonas coralicida and Aurantimonas manganoxydans (98.2, 98.1 and 97.9% sequence similarity, respectively). The predominant cellular fatty acid of strain SW136T was C18 : 1 ω7c. Strain SW136T contained ubiquinone-10 as the dominant respiratory quinone, and diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and phosphatidylglycerol as the major polar lipids. The genomic DNA G+C content was 64.3 mol%. The average nucleotide identity and digital DNA–DNA hybridization values of strain SW136T with A. coralicida CGMCC 1.12222T and A. manganoxydans CGMCC 1.12225T were 78.8 and 78.6 % and 21.5 and 25.5 %, respectively. On the basis of phylogenetic inference and phenotypic characteristics, we propose that strain SW136T represents a novel species of the genus Aurantimonas , with the name Aurantimonas marina sp. nov. The type strain is SW136T (=CGMCC 1.17725T=KCTC 82366T).
