Abstract:

The biological mechanism of Streptomyces TOR3209 volatile organic compounds(VOCs)promoting tobacco growth and development was studied.The growth-promoting properties of VOCs in the fermentation broth were identified by two separate plates,and the VOCs components were analyzed by solid phase microextraction and gas chromatography-mass spectrometry.VOCs of Streptomyces TOR3209 at different concentrations could promote the growth of tobacco,and the effect of adding 5 mL(6×107 CFU/mL)strain fermentation liquid was the most significant in the treatment group,which increased 238% compared with the control group.A total of 32 substances were extracted from the VOCs of Streptomyces TOR3209 fermentation broth,and the growth-promoting function of dinbutyl adipate was verified.The results showed that dinbutyl adipate of different mass concentrations could promote the growth of tobacco,and the growth promoting effect of 1 mol/mL was the most significant.Through transcriptome analysis,it was found that many genes such as laccase were up-regulated in the tobacco treated group compared with the control group.VOCs of Streptomyces TOR3209 had a significant growth promoting effect on tobacco,and dinbutyl adipate regulated several growth promoting genes in tobacco.This study clarified the mechanism of the VOCs of Streptomyces TOR3209 regulating tobacco growth and development,and provided a theoretical basis for the development of efficient and environmentally friendly microbial production promotion products and the application evaluation.
