“…Acidovorax has been mostly considered as biotrophic pathogen [11]. However, bacteria of this genus are also known as commensal species or plant beneficial bacteria, which produce secondary metabolites and hormones promoting plant growth, as well as competing with pathogens [12].…”

Beta-proteobacteria belonging to the genus Acidovorax have been described from various environments. Many strains can interact with a range of hosts, including humans and plants, forming neutral, beneficial or detrimental associations. In the frame of this study we investigated genomic properties of 52 bacterial strains of the genus Acidovorax, isolated from healthy roots of Lotus japonicus, with the intent of identifying traits important for effective plant-growth promotion. Based on single-strain inoculation bioassays with L. japonicus, performed in a gnotobiotic system, we could distinguish 7 robust plant-growth promoting strains from strains with no significant effects on plant-growth. We could show that the genomes of the two groups differed prominently in protein families linked to sensing and transport of organic acids, production of phytohormones, as well as resistance and production of compounds with antimicrobial properties. In a second step, we compared the genomes of the tested isolates with those of plant pathogens and free-living strains of the genus Acidovorax sourced from public repositories. Our pan-genomics comparison revealed features correlated with commensal and pathogenic lifestyle. We could show that commensals and pathogens differ mostly in their ability to use plant-derived lipids and in the type of secretion-systems being present. Most free-living Acidovorax strains did not harbour any secretion-systems. Overall, our data indicated that Acidovorax strains undergo extensive adaptations to their particular lifestyle by horizontal uptake of novel genetic information and loss of unnecessary genes.

“…The second group is formed by the plant-pathogenic species A. anthurii, A. avenae and A. konjaci (Willems & Gillis, 2015). Acidovorax avenae consists of three subspecies (avenae, cattleyae and citrulli) that cause a wide range of economically important diseases in monocotyledonous and dicotyledonous plants (Giordano et al, 2012;Willems & Gillis, 2015). However, these three subspecies have different host ranges.…”

“…cattleyae infects only orchid species belonging to the genera Cattleya and Phalaenopsis. Aaa has a wide host range in the Poaceae family, including maize, rice, sorghum, oats, barley, rye, various millets, vasey grass and sugarcane (Martin & Wismer, 1989;Song et al, 2003;Fontana et al, 2013;Willems & Gillis, 2015), as well as tea (Schaad et al, 2008), white bird of paradise (Strelitzia nicolai; Seijo & Peres, 2011) and creeping bentgrass (Agrostis stolonifera; Giordano et al, 2012).…”

Red stripe caused by the bacterium Acidovorax avenae subsp. avenae (Aaa) is a disease of sugarcane that is distributed worldwide. In this study, 108 sugarcane leaf samples were collected in 2013–2016 from nine sugarcane‐growing regions in China. Aaa was detected by PCR with specific and novel primers from the 16S–23S rDNA internal transcribed spacer region in 81 of 84 (96%) leaves with red stripe symptoms and in 20 of 24 (83%) leaves without symptoms. Furthermore, Aaa was detected in all nine sampling locations representing six sugarcane‐producing provinces in China. The 101 amplified fragments were cloned and sequenced. The size of the nucleotide sequences varied from 436 to 454 bp and the sequence identity ranged from 89.2% to 100%, suggesting a significant genetic variation among Aaa strains from China. Five major restriction fragment length polymorphism (RFLP) profiles were obtained by in silico and polyacrylamide gel electrophoresis analyses of the PCR products digested with HindIII and EcoRI. The causal agent of sugarcane red stripe was also successfully isolated from a diseased plant and its pathogenicity confirmed by inoculation of healthy sugarcane plantlets and reproduction of disease symptoms. The data showed that Aaa is currently widespread in China, suggesting that control methods should be implemented to limit the impact of red stripe on sugarcane production.

“…Decline includes chlorosis and necrosis that can lead to severe thinning throughout the turfgrass stand (Latin, 2012). Recent reports show that bacteria ( Acidovorax avenae and Xanthomonas translucens ) are causal agents in etiolation (Giordano et al, 2012; Roberts et al, 2014). Acidovorax species cause bacterial brown stripe of creeping bentgrass ( Agrostis stolonifera L.) (CBG) turf in Japan (Furuya et al, 2009), and Giordano et al (2012) observed that infection by Acidovorax avenae subsp.…”

Etiolation is an abnormal elongation and chlorosis of turfgrass plants that has become problematic in recent years, and bacteria have been implicated as causal agents. The frequent reports of etiolation are of concern to turfgrass managers, since management practices for bacterial diseases in turf are not well developed. The purpose of this research trial was to evaluate fungicides and nonregistered antibiotics for management of etiolation in creeping bentgrass turf. This 2‐year field study evaluated oxytetracycline, streptomycin sulfate, acibenzolar‐S‐methyl + chlorothalonil (ASM + C), potassium phosphite (PPP), hydrogen dioxide, fosetyl‐Al [pigmented (FAP) and nonpigmented (FA)], and copper + mancozeb for their effects on etiolation caused by Xanthomonas translucens on creeping bentgrass putting‐green turf. Reductions in etiolation severity were observed with oxytetracycline treatment in both years and with ASM + C in the second year of study. While ASM + C did not reduce etiolation in the first year, turf quality with ASM + C alone and in combination with PPP was superior to all other treatments in both years. While PPP and FAP did not reduce etiolation, turf quality of these plots was often better than the control. Both antibiotics in addition to copper + mancozeb had phytotoxicity that reduced turf quality. Preventative applications of ASM + C were the most effective in reducing etiolation of creeping bentgrass while maintaining turf quality.
