We investigated conserved and variable regions of the mxaF gene and amino acid sequence in methylotrophic strain M1K isolated from saline soil rhizosphere and belonging to Methylophaga genus. The significant heterogeneity was revealed in methano- and methylotrophic bacteria by method of Minimum Evolution. The ability of strain to influence indole-3-acetic acid synthesis from L-tryptophan and halotolerance are the arguments in favor of application in new agrotechnology.
