Fig. 1From: A survey of Methylobacterium species and strains reveals widespread production and varying profiles of cytokinin phytohormonesTotal cytokinin (CK) concentration (pmol mL−1) in 46 Methylobacterium strains. Strains were cultured in vitro in the DSM125 minimal medium until they reached the early stationary phase. Cytokinin were analysed in the cell-free bacteria supernatants using HPLC-(ESI +)MS/MS. Values are means ± SE of 3 replicatesBack to article page
