Methylobacterium oryzihabitans sp. nov., isolated from water sampled from a rice paddy field

Fine-Scale Adaptations to Environmental Variation and Growth Strategies Drive Phyllosphere Methylobacterium Diversity

“…Experimental studies have shown the important roles of Methylobacterium in plant physiology, including growth stimulation through hormone secretion ( 25 – 27 ), heavy metal sequestration ( 27 ), antiphytopathogenic compound secretion, and nitrogen fixation in plant nodules ( 28 ), sparking increasing interest in the use of Methylobacterium in plant biotechnology applications ( 27 , 29 , 30 ). Although up to 64 Methylobacterium species have been described ( 31 – 39 ), genomic and phenotypic information was until recently limited to a small number of model species: M. extorquens , M. populi , M. nodulans , M. aquaticum , and M. radiotolerans , mostly isolated from anthropogenic environments and only rarely from plants ( 40 – 44 ). Additionally, Methylobacterium was mostly isolated assuming that its optimal growth was in the range of 25 to 30°C ( 45 ), an approach that could bias strain collections toward mesophyllic isolates to the exclusion of isolates from temperate forests, where temperatures typically range from 10 to 20°C during the growing season ( 46 ).…”

Methylobacterium nonmethylotrophicum sp. nov., isolated from tungsten mine tailing

“…oryzihabitans and M. aquaticum [5, 6]. In this study, we introduce a novel member of clade C in the genus Methylobacterium , designated 6HR-1 T , by using polyphasic taxonomic approach.…”

Comprehensive Phylogenomics of Methylobacterium Reveals Four Evolutionary Distinct Groups and Underappreciated Phyllosphere Diversity

“…Although more than 60 Methylobacterium species have been described so far ( Green and Ardley 2018 ; Chen et al 2019 ; Feng et al 2020 ; Jia et al 2020 ; Kim, Chhetri, Kim, Lee et al 2020 ; Kim, Chhetri, Kim, Kim et al 2020 ; Ten et al 2020 ; Jiang et al 2020 ; Pascual et al 2020 ; Alessa et al 2021 ), available genomic and phenotypic information was until recently limited to a few model species, mostly from groups B and C, and mostly isolated from anthropogenically impacted environments, and in rare cases from plants ( Marx et al 2012 ; Tani et al 2015 ; Minami et al 2016 ; Morohoshi and Ikeda 2016 ; Belkhelfa et al 2018 ). Surveys of Methylobacterium diversity associated with plants have mainly focused on the rhizosphere, especially in crop species ( Sy et al 2001 ; Jourand et al 2004 ; Grossi et al 2020 ).…”
