Abstract Background While leaves are far more accessible for analysing plant defences, roots are hidden in the soil, leading to difficulties in studying soil-borne interactions. Inoculation strategies for infecting model plants with model root pathogens are described in the literature, but it remains demanding to obtain a methodological overview. To address this challenge, this study uses the model root pathogen Verticillium longisporum on Arabidopsis thaliana host plants and provides recommendations for selecting appropriate infection systems to investigate how plants cope with root pathogens. Results A novel root infection system is introduced, while two existing ones are precisely described and optimized. Step-by-step protocols are presented and accompanied by pathogenicity tests, transcriptional analyses of indole-glucosinolate marker genes and independent confirmations using reporter constructs. Advantages and disadvantages of each infection system are assessed. Overall, the results validate the importance of indole-glucosinolates as secondary metabolites that limit the Verticillium propagation in its host plant. Conclusion Detailed assistances on studying host defence strategies and responses against V. longisporum is provided. Furthermore, other soil-borne microorganisms (e.g., V. dahliae) or model plants, such as economically important oilseed rape and tomato, can be introduced in the infection systems described. Hence, these proven manuals can support finding a root infection system for your specific research questions to further decipher root-microbe interactions.

Four phenotypically similar bacterial strains isolated from fungal, plant, and human sources were identified as Azospirillum species. Strains RC1 and LOD4 were isolated from the mycelium of the apple root pathogen Rhizoctonia solani AG 5 and from the rhizosphere of wheat grown in apple orchard soil, respectively. Strains C610 and F4626 isolated from human wounds were previously misclassified as Roseomonas genomospecies 3 and 6. All four strains demonstrated close similarities in 16S rRNA gene sequences, having [Formula: see text]97% identity to Azospirillum brasilense type strain ATCC 29145 and <90% identity to Roseomonas gilardii, the Roseomonas type strain. Extensive phenotypic similarities among the four strains included the ability of free-living cells to fix N2. Cells of strains RC1, LOD4, and C610 but not of strain F4626 could be induced to flocculate by incubation with 10 mmol·L–1glycerol or fructose in medium containing 0.5 mmol·L–1NO3–. Our results indicate a wide range of potential sources for Azospirillum spp. with the isolation of Azospirillum spp. from human wounds warranting further investigation.Key words: Azospirillum brasilense, Roseomonas fauriae, flocculation, Rhizoctonia solani.

Abstract G. philippii was described as a root pathogen that is particularly destructive to tropical plantation crops, especially rubber (Steyaert, 1975a). It occurs on many woody and non-woody plant hosts in South-East Asia through Indonesia to Papua New Guinea and New Caledonia (UK CAB International, 1993). Acacia trees are considered as invasive species and as an economic crop (Koutika and Richardson, 2019) and the significance of the disease is from both aspects. A similar situation exists for other trees such as Eucalyptus (Deus et al., 2019). These trees are being considered to combat climate change by absorbing carbon dioxide and consequently disease is extremely important. Red root rot is a significant disease of tropical plantations in South-East Asia. In severely infected areas in Malaysia, root rot caused more than 40% mortality of Acacia trees aged between 9 and 14 years. In Indonesia, the disease can kill up to 28% of trees in second-rotation A. mangium plantations in Sumatra and Kalimantan. Second rotation A. mangium and A. crassicarpa plantations trees as young as 6 months old may be killed by red root disease (Gafur et al., 2015).
