Abstract
A Gram-staining-positive actinomycete named YZH12T was isolated from the sediment of the Yangtze River in Nanjing, Jiangsu province, China. Cells were aerobic, non-spore forming, non-motile, short rod (0.4-0.6 × 0.5-1.0 µm) or coccus (0.4-0.6 µm in diameter). Colonies were circular, smooth, and beige to yellowish. Growth occurred at 15-42 °C (optimal 28 °C), pH 5.0-9.0 (optimal 7.0), and 0-10% (w/v) NaCl (optimal 2%). The strain could tolerate 1500 mg/L of imazamox. Strain YZH12T showed 98.7% 16S rRNA gene sequence similarity Nocardioides zeae JM-1068T and less than 97% similarities with other type strains in the genus Nocardioides. Phylogenetic analysis based on genome and 16S rRNA gene sequences indicated that strain YZH12T was phylogenetically affiliated to the genus Nocardioides and formed a subclade with N. zeae JM-1068T and N. alkalitolerans DSM 16699T. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between YZH12T and closely related type strain N. zeae JM-1068T were 79.9% and 35.2%, respectively. The major fatty acids (> 5%) were C18: 1ω9c, iso-C16: 0, C16: 0, C17: 1ω8cand C18: 0; the major respiratory quinone was MK-8(H4); and the polar lipids profiles were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), glycolipid (GL), two aminophospholipids (APL1, APL2), and an unknown polar lipid (L). The genomic DNA G + C content is 73.5%. Based on the phenotypic, chemotaxonomic, phylogenetic analyses, and genomic data, strain YZH12T represents a novel species of the genus Nocardioides, for which the name Nocardioides imazamoxiresistens YZH12T is proposed, with strain YZH12T (= KCTC 49964T = MCCC 1K0892T) as the type strain.

Abstract
A Gram-stain-positive, rod-shaped, non-spore-forming and non-motile bacterium, designated WY-20T, was isolated from a lakeside soil sample collected in Jiangxi Province, PR China. Growth was observed at 20-42 °C (optimum 30 °C), pH 5.0-8.0 (optimum pH 7.0) and salinity of 0-3.0% (w/v; optimum 0.5%). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain WY-20T belongs to the genus Nocardioides and showed the highest sequence similarity (98.1%) to N. phosphati WYH11-7T, followed by N. cavernaquae K1W22B-1T (97.8%), N. marmoriterrae JOS5-1T (97.2%) and N. jensenii NBRC 14755T (97.1%). The average nucleotide identity and digital DNA-DNA hybridization values between strains WY-20T and N. phosphati WYH11-7T were 83.5% and 26.2%, respectively. The predominant fatty acids (≥ 10% of the total fatty acids) were C18:1ω9c, C17:0, C16:0, summed feature 8 (C18:1ω7c and/or C18: 1ω6c) and C17:1ω9c. The major menaquinone was MK-8 (H4). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and two unidentified phospholipids. In addition, meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Based on phenotypic, genotypic and phylogenetic pieces of evidence, strain WY-20T represents a novel species in the genus Nocardioides, for which the name Nocardioides jiangxiensis sp. nov. is proposed. The type strain is WY-20T (= GDMCC 4.317T = KACC 23379T).

Abstract
Six Gram-stain-positive, aerobic and irregular-rod-shaped actinobacteria (ZJ1313T, ZJ1307, MC1495T, Y192, 603T and X2025) were isolated from the Qinghai-Tibet Plateau of China and were characterized using a polyphasic taxonomic method. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the six new strains formed three distinct clusters within the genus Nocardioides, and strains ZJ1313T and ZJ1307 were most closely related to N. solisilvae JCM 31492T (16S rRNA gene sequence similarity, 98.0 %), MC1495T and Y192 to N. houyundeii 78T (98.5 %), and 603T and X2025 to N. dokdonensis JCM 14815T (97.6 %). The digital DNA-DNA hybridization values of strains ZJ1313T, MC1495T and 603T among each other and with type strains of their closest relatives were all below the 70 % cut-off point, but values within each pair of new strains were all higher than the threshold. The major fatty acids of these strains were iso-C16 : 0, C17 : 1 ω8c or C18 : 1 ω9c. MK-8(H4) was the predominant respiratory menaquinone and ʟʟ-2,6-diaminopimelic acid was the diagnostic diamino acid. All the strains shared diphosphatidylglycerol (predominant), phosphatidylglycerol, phosphatidylcholine and phosphatidylinositol as the common polar lipids, with minor difference in the types of unidentified phospholipids, glycolipids and lipids. The G+C contents based on genomic DNA of strains ZJ1313T, MC1495T and 603T were 72.5, 72.1 and 73.2 mol%, respectively. The above results suggested that strain pairs ZJ1313T/ZJ1307, MC1495T/Y192 and 603T/X2025 represent three new species of genus Nocardioides, for which the names Nocardioides ochotonae sp. nov. (ZJ1313T=GDMCC 4.177T=KCTC 49537T=JCM 34185T), Nocardioides campestrisoli sp. nov. (MC1495T=GDMCC 4.176T=KCTC 49536T=JCM 34307T) and Nocardioides pantholopis sp. nov. (603T=CGMCC 4.7510T=DSM 106494T) are proposed accordingly.

Abstract
An aerobic, Gram-stain-positive, non-motile, dull-yellow, short rod-shaped actinomycete strain, designated G10T, was isolated from Tagetes patula (marigold) roots collected from Goyang in the Republic of Korea. The isolate showed best growth on Reasoner's 2A agar at 25 °C, pH 6.5.0 and with 0% NaCl (w/v). The strain was negative for oxidase activity and positive for catalase activity. On the basis of 16S RNA gene sequence similarity, strain G10T was affiliated to the genus Nocardioides and the closest species were Nocardioides glacieisoli HLT3-15T (98.8 %), Nocardioides zhouii HLT2-9T (98.8 %), Nocardioides ganghwensis JC2055T (98.7 %), Nocardioides cavernae YIM A1136T (98.6 %), Nocardioides flavus Y4T (98.5 %), Nocardioides oleivorans DSM 16090T (98.3 %), Nocardioides alpinus Cr7-14T (98.2 %), Nocardioides exalbidus DSM 22017T (98.1 %) and Nocardioides hwasunensis KCTC 19197T (98.1 %). Strain G10T formed a monophyletic cluster with N. glacieisoli HLT3-15T, N. zhouii HLT2-9T and N. hwasunensis KCTC 19197T in all phylogenetic trees. The cell-wall peptidoglycan of strain G10T contained ll-diaminopimelic acid as the diagnostic amino acid. The predominant fatty acids were iso-C16 : 0 and C17 : 1 ω8c. MK-8(H4) was the major isoprenoid quinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol. Average nucleotide identity and digital DNA-DNA hybridization values were 78.6-88.7 % and 21.5-36.2 %, respectively, with the type strains of related species of the genus Nocardioides, suggesting that strain G10T represents a novel species. The genome of strain G10T is 4 231 000 bp long with a DNA G+C content of 71.5 mol% and encodes 4071 predicted proteins, six rRNAs and 46 tRNAs. The genome of strain G10T comprises the biosynthetic gene cluster for T3PKS, terpene, NRPS-like fragment and RRE-containing element as secondary metabolites. The results of taxonomic, phylogenetic, biochemical, chemotaxonomic and genomic analysis clearly supported that strain G10T represent a novel species within the genus Nocardioides, for which the name Nocardioides baculatus sp. nov is proposed and the type strain is G10T (=KCTC 49626T=NBRC 114801T).

Abstract
Microbial communities associated with the plant phyllosphere and endosphere can have both beneficial as well as detrimental effects on their hosts. There is an ongoing debate to which extend the phyllosphere and endosphere microbiome assembly is controlled by the host plant how pronounced cultivar effects are. We investigated the bacterial and fungal communities from the phyllosphere and endosphere of 10 different rice cultivars grown under identical environmental conditions in the frame of a targeted approach to identify drivers of community assembly. The results indicated that the endophytic bacterial communities were clearly separated into two groups. The α-diversity and microbial network complexity within Group I were significantly lower than in Group II. Moreover, the genera Nocardioides, Microvirga, and Gaiella were significantly more abundant in Group II and only present in the interaction networks of this group. These three genera were significantly correlated with α- and β-diversity of the endophytic bacterial community and thus identified as major drivers of the endosphere community. We have identified keystone taxa that shape endophytic bacterial communities of different rice cultivars. Our overall findings provide new insights into plant-microbe interactions, and may contribute to targeted improvements of rice varieties in the future.

Abstract
Due to the sequence homology between the bacterial 16S rRNA gene and plant chloroplast and mitochondrial DNA, the taxonomic characterization of plant microbiome using amplicon-based high throughput sequencing often results in the overwhelming presence of plant-affiliated reads, preventing the thorough description of plant-associated microbial communities. In this work we developed a PCR blocking primer assay targeting the taxonomically informative V5-V6 region of the 16S rRNA gene in order to reduce plant DNA co-amplification, and increase diversity coverage of associated prokaryotic communities. Evaluation of our assay on the characterization of the prokaryotic endophytic communities of Zea mays, Pinus taeda and Spartina alternifora leaves led to significantly reducing the proportion of plant reads, yielded 20 times more prokaryotic reads and tripled the number of detected OTUs compared to a commonly used V5-V6 PCR protocol. To expand the application of our PCR-clamping assay across a wider taxonomic spectrum of plant hosts, we additionally provide an alignment of chloroplast and mitochondrial DNA sequences encompassing more than 200 terrestrial plant families as a supporting tool for customizing our blocking primers.

Abstract
Two novel Gram-stain-positive, irregular rod-shaped bacterial strains, dk3136T and dk3543, were isolated from the faeces of Tibetan gazelle (Procapra picticaudata) in the Qinghai-Tibet Plateau of PR China. The cells were aerobic, oxidase-negative and catalase-positive. Colonies were yellowish, circular without any observable aerial mycelium after culturing at 28 ℃ for 3 days on brain-heart infusion (BHI) agar with 5 % sheep blood. The cells grew optimally at 28 °C, pH 7.5 and with 1 % (w/v) NaCl on BHI agar supplemented with 5 % sheep blood. Phylogenetic analysis of the 16S rRNA gene sequences revealed that their nearest phylogenetic relative was Nocardioides solisilvae Ka25T (97.9 % similarity). The results of 16S rRNA gene sequence and phylogenetic/phylogenomic analyses illustrated that N. solisilvae Ka25T, Nocardioides gilvus XZ17T, Nocardioides houyundeii 78T and Nocardioides daphniae D287T were their nearest phylogenetic neighbours. The DNA G+C contents of strains dk3136T and dk3543 were 70.3 mol% and 70.4 mol%, respectively. Their genomes exhibit lower than threshold (95-96 %) average nucleotide identity to known species of the genus Nocardioides. ll-2,6-diaminopimelic acid was the diagnostic diamino acid and MK-8(H4) was the predominant respiratory quinone. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The two strains had C18 : 1 ω9c, iso-C16 : 0 and C17 : 1 ω8c as the major fatty acids, and rhamnose and galactose as the main whole-cell sugars. On the basis of the results of our genotypic, phenotypic and biochemical analyses, we conclude that strains dk3136T and dk3543 represent a novel species in genus Nocardioides, for which the name Nocardioides jishulii sp. nov. is proposed. The type strain is dk3136T (=CGMCC 4.7570T=JCM 33496T=KCTC 49314T).

Abstract
Two novel Gram-stain-positive, irregular rod-shaped actinomycetes, S-1144T and 4053, were isolated from leaves of Lamiophlomis rotata on the Qinghai-Tibet Plateau, PR China. Cells were aerobic, catalase-positive and oxidase-negative. Colonies on Reasoner's 2A agar were light yellow, circular, shiny, smooth and convex after 2 days of incubation. The isolates grew optimally at 25 °C, pH 7.5 and with 0 % (w/v) NaCl. The results of polyphasic analyses indicated that strain S-1144T belonged to the genus Nocardioides and its close phylogenetic neighbours (16S rRNA gene sequence similarity) were Nocardioides litoris DSM 103718T (98.4 %), Nocardioides rubriscoriae DSM 23986T (98.2%) and Nocardioides plantarum DSM 11054T (97.8 %). The genome of strain S-1144T showed less than 70 % digital DNA-DNA hybridization and < 95-96 % average nucleotide identity values to the above reference strains. The DNA G+C content of strain S-1144T was 73.5 mol%. MK-8(H4) was the predominant respiratory quinone (96.0 %) and llLL-2,6-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The polar lipid profile of strain S-1144T consisted of diphosphatidylglycerol, phosphatidylglycerol, three unidentified phospholipids, one unidentified glycolipid and one unidentified lipid. The major cellular fatty acids were iso-C16 : 0, C17 : 1 ω8c, C17 : 0 and C18 : 1 ω9c. On the basis of obtained data, strain S-1144T represented a novel species of the genus Nocardioides, for which the name Nocardioides dongxiaopingii sp. nov. is proposed. The type strain is S-1144T (=CGMCC 4.7568T=JCM 33469T).

Abstract
In the present study, we describe two novel Gram-stain-positive, irregular rod-shaped bacterial strains, 78T and 601, that had been isolated from the faeces of Tibetan antelopes at the Hoh Xil Nature Reserve, Qinghai-Tibet Plateau, China. The cells were aerobic, oxidase-negative and catalase-positive. When cultured on brain-heart infusion agar supplemented with 5 % sheep blood, colonies were cream in colour, circular, smooth and convex. Phylogenetic analysis based on the full-length 16S rRNA sequences revealed that type strain 78T and strain 601 belong to the genus Nocardioides, sharing the highest similarity to Nocardioides solisilvae JCM 31492T (98.3 %), Nocardioides gilvus XZ17T (97.4 %) and Nocardioides daejeonensis JCM 16922T (97.4 %). The average nucleotide identity values between the two novel strains and the three closely related type strains of the genus Nocardioides were lower than the 95-96 % threshold. The DNA G+C content of strains 78T and 601 were 71.2 and 71.3 mol% respectively. MK-8 (H4) was the predominant respiratory quinone and ll-2,6-diaminopimelic acid was the diagnostic diamino acid in its cell-wall peptidoglycan. Its polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, an unidentified phospholipid and an unidentified lipid. The main whole-cell sugars were rhamnose, xylose and galactose and the major fatty acids (>10 %) were C17 : 1ω8c, iso-C16 : 0 and C18 : 1ω9c. These data supported the affiliation of strains 78T and 601 to genus Nocardioides. Based on evidence collected from the phenotypic, genotypic and phylogenetic analyses, we propose a novel species named Nocardioideshouyundeii sp. nov. The type strain is 78T (=CGMCC 4.7461T=DSM 106424T).

Abstract
A Gram-positive, non-motile, rod-shaped bacterial strain, designated HH06T, was isolated from a nodule of Astragalus chrysopterus in northwestern China. Phylogenetic analysis of the 16S rRNA gene sequence showed that the strain is closely related to Nocardioides alpinus Cr7-14T and Nocardioides furvisabuli DSM 18445T with 98.5 and 98.1% similiarity, respectively. Growth was observed at 4–28 °C in R2A medium (optimum at 25 °C), at 10–30 °C in YMA and LB medium (optimum in both at 28 °C) and at pH 5.0–10.0 in R2A medium (optimum at pH 7.0–8.0). The cell wall peptidoglycan was found to contain LL-diaminopimelic acid as the principal diamino acid and MK-8(H4) was identified as the predominant menaquinone. The major polar lipids were identified as phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, two unidentified glycolipids and two unidentified polar lipids. The major fatty acids were identified as iso-C16:0 (32.8%) and C18:1ω9c (15.1%). The DNA G+C content of strain HH06T was determined to be 71.4 mol%. Based on phenotypic, chemotaxonomic, phylogenetic properties and DNA–DNA relatedness, it is concluded that strain HH06T represents a novel species of the genus Nocardioides, for which the name Nocardioides astragali sp. nov. is proposed. The type strain is HH06T (= CGMCC 4.7327T = NBRC 112322T).

Abstract
A Gram-staining-positive, aerobic non-spore-forming and short-rod-shaped endophytic actinomycete was isolated from a branch of Sonneratia apetala, designated strain BGMRC0092T and investigated in detail data to determine its taxonomic position. On the basis of the 16S rRNA gene sequence analysis, the results of the phylogenetic analyses indicated that BGMRC0092T was most closely related to Nocardioides alpinus Cr7-14T (96.9 %), Nocardioides oleivorans DSM16090T (96.4 %) and Nocardiodes exalbidus RC825T (96.3 %). The predominant cellular fatty acids of BGMRC0092T were iso-C16 : 0 and C18 : 1ω8c. The major menaquinone was MK-8(H4). The diagnostic diamino acid in the cell-wall peptidoglycan was ll-2,6-diaminopimelic acid. The predominant cell-wall sugars were composed of galactose, mannose, rhamnose and xylose. The polar lipid pattern contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, one unknown phospholipid and three unknown polar lipids. The DNA G+C content was 69.3 mol%. On the basis of phenotypic and chemotaxonomic characteristics and the results of phylogenetic analysis, BGMRC0092T represents a novel species of the genus Nocardioides, for which the name Nocardioides sonneratiae sp. nov. is proposed. The type strain is Nocardioides sonneratiae BGMRC0092T (=KCTC 39565T=NBRC 110251 T=DSM 100390T).

Abstract
A Gram-stain-positive, aerobic and yellow actinobacterial strain, designated SYP-A7303T, was isolated from the root of Ginkgo biloba L. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain SYP-A7303T belongs to the genus Nocardioides. The 16S rRNA gene sequence of strain SYP-A7303T showed highest similarity to Nocardioides marinus CL-DD14T ( = JCM 15615T) (98.3 %) and Nocardioides aquiterrae GW-9T ( = JCM 11813T) (97.1 %), and less than 96.9 % to the type strains of other species of the genus Nocardioides. Strain SYP-A7303T grew optimally at 28 °C, pH 7.0 and in the absence of NaCl. It contained ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, with mannose, ribose, rhamnose, glucose and galactose as whole-cell sugars. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and an unknown lipid. The menaquinone was MK-8(H4) and the predominant cellular fatty acids were iso-C16 : 0, C18 : 1ω9c and C17 : 1ω8c. The DNA G+C content was 72 mol%. Mean DNA-DNA relatedness values between strain SYP-A7303T and the closely related strains N. marinus JCM 15615T and N. aquiterrae JCM 11813T were 62.5 ± 2.4 and 56.5 ± 3.5 %, respectively. Based on the morphological, physiological, biochemical and chemotaxonomic characteristics presented in this study, strain SYP-A7303T represents a novel species of the genus Nocardioides, for which the name Nocardioides ginkgobilobae sp. nov. is proposed. The type strain is SYP-A7303T ( = DSM 100492T = KCTC 39594T).

Abstract
A Gram-stain-positive, aerobic organism was isolated as an endophyte from the stem tissue of healthy maize (Zea mays) and investigated in detail for its taxonomic position. On the basis of the 16S rRNA gene sequence analysis, strain JM-601T was shown to be most closely related to Nocardioides alpinus (98.3%), and Nocardioides ganghwensis (98.0%). The 16S rRNA gene sequence similarity to all other species of the genus Nocardioides was ≤ 98.0%. The diagnostic diamino acid of the peptidoglycan was ll-diaminopimelic acid. The major quinone of strain JM-601T was menaquinone MK-8(H4). The polar lipid profile revealed the major components diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylcholine and an unidentified phospholipid. The polyamine pattern contained predominantly spermine and moderate amounts of spermidine. In the fatty acid profile, iso-C16:0, C17:1ω8c and 10-methyl C17:0 were present in major amounts. All these data support the allocation of the strain to the genus Nocardioides. The results of physiological and biochemical characterization allow in addition a phenotypic differentiation of strain JM-601T from N. alpinus and N. ganghwensis. Strain JM-601T represents a novel species of the genus Nocardioides, for which we propose the name Nocardioides zeicaulis sp. nov., with JM-601T (=CCM 8654T=CIP 110980T) as the type strain.

Abstract
A Gram-stain-positive, aerobic, non-motile, rod-shaped, yellow-pigment-producing bacterium, (designated strain CC-CZW004T), was isolated from seafood samples (sea urchins) at Penghu Island in Taiwan. Strain CC-CZW004T grew optimally at pH 7.0 and 30 °C in the presence of 3 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA genes revealed a distinct taxonomic position attained by strain CC-CZW004T with respect to other members of the genus Nocardioides. The novel strain shared highest 16S rRNA gene sequence similarities to Nocardioides daejeonensis JCM 16922T (96.4 %), Nocardioides pacificus JCM 19260T (96.3 %), and Marmoricola scoriae JCM 17444T (96.2 %). The major fatty acids of strain CC-CZW004T consisted of C17:0, C16:1ω5c, C17:1ω8c`, iso-C16:0 and C19:1ω11c/C19:1ω9c (summed feature 6). The diagnostic diamino acid in the cell wall was ll-2,6-diaminopimelic acid. The polar lipid profile was composed of major amounts of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and aminophospholipid. The DNA G+C content was 73.3 mol%. The predominant quinone system was menaquinone (MK-8). On the basis of polyphasic taxonomic evidences presented here, strain CC-CZW004T represents a novel species of the genus Nocardioides, for which the name Nocardioides echinoideorum sp. nov. is proposed. The type strain is CC-CZW004T ( = BCRC 16974T = JCM 30276T).
