Abstract

Microorganisms associated with nematodes or enriched in galls have been reported previously to aid plant-parasitic nematodes (PPNs) in infecting and establishing parasitism in the host plants. However, the rhizosphere-associated microbiota, which strengthens the pathogenicity of PPNs, remains largely unknown. This study illustrated rhizosphere bacteria enhancing Meloidogyne incognita infection on Arabidopsis thaliana by comparing the gall numbers of the treatments between natural soil and the sterile soil or soils drenched with antibiotics. By culture-dependent and pot testing methods, sixteen bacterial combinations from rhizosphere soils of A. thaliana were demonstrated to enhance M. incognita pathogenicity, including the most effective Nocardioides. Single-strain inoculation from the Nocardioides combination significantly resulted in M. incognita forming more galls on roots than the control, in which N. nematodiphilus R-N-C8 was the most effective strain. Strain R-N-C8 could substantially facilitate the M. incognita second-stage juveniles (J2s) moving towards the roots of A. thaliana and infecting the roots by releasing chemoattractant to attract J2s. The chemoattractant from strain R-N-C8 was determined to be L-lysine. This study furnishes vital insights for understanding the infection of root-knot nematodes associated with rhizosphere microbes.

Abstract

A novel strain, 1433T, was isolated from leaves of Chinese red pepper (Huajiao, Zanthoxylum bungeanum Maxim) collected from Gansu province in northwestern China, and was characterised by a polyphasic approach. Cells of strain 1433T were observed to be Gram-stain positive, aerobic, asporogenous, rod shaped, motile and to have peritrichous flagella. The strain was observed to grow at a range of temperatures and pH, 4–45 °C (optimum 28–32 °C) and 6.0–10.0 (optimum pH 6.0–7.0), respectively. Growth was found to occur in the presence of 0–7% (w/v) NaCl [optimum 0–3% (w/v)]. The G+C content of the genomic DNA was determined to be 41.9 mol% and the cell wall peptidoglycan found to contain meso-diaminopimelic acid. The predominant menaquinone was identified as MK-7 and the major polar lipids as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unidentified polar lipid and three unidentified phospholipids. The major cellular fatty acids were identified as iso-C15:0 (31.6%), anteiso-C15:0 (26.9%) and iso-C14:0 (17.1%). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 1433T is a member of the genus Bacillus and is closely related to Bacillus aryabhattai DSM 21047T (99.4% sequence similarity) and Bacillus megaterium DSM 32T (99.2%). DNA–DNA relatedness of the novel strain 1433T with B. aryabhattai DSM 21047T and B. megaterium DSM 32T was 33.8 ± 2.8% and 28.9 ± 3.4%, respectively. On the basis of the polyphasic evidence presented, strain 1433T is considered to represent a novel species of the genus Bacillus, for which we propose the name Bacillus zanthoxyli sp. nov. The type strain is 1433T (= CCTCC AB 2016326T = KCTC33730T).
