Determination of potential plant growth promoting compounds from Ochrobactrum sp. (MH685438) by thermal desorption-gas chromatography

Abstract

Volatile organic compounds (VOCs) produced by plant growth promoting rhizobacteria (PGPR) has emerged as a mode of communication between bacteria and plants. In current study in vitro experiment was conducted to investigate the effect of volatile organic compounds (VOCs) produced by the plant growth promoting rhizobacterium Ochrobactrum sp. (MH685438) on Nicotiana tabacum. Volatile organic compound (VOCs) emitted from the Ochrobactrum sp. was evaluated under in vitro were resulted in significant growth promotion on tobacco plants. VOCs emitted by Ochrobactrum sp. was identified through gas chromatography/mass spectrometry- thermal desorption (GC-MS-TD) analysis. These results suggest that a volatile compound released from Ochrobactrum sp. significantly enhances the plant growth promotion.
