Exposure to an Environmentally Isolated Strain TC09 of Triggers Plant Growth Promotion, Early Flowering, and Fruit Yield Increase.

A growing number of bacteria and fungi have been found to promote plant growth through mutualistic interactions involving elements such as volatile organic compounds (VOCs). Here, we report the identification of an environmentally isolated strain of (herein named TC09), that substantially enhances plant growth after exposure beyond what has previously been reported. When cultured on Murashige and Skoog (MS) medium under conditions, tobacco seedlings () exposed to TC09 cultures for 20 days increased stem height and whole plant biomass up to 25- and 15-fold, respectively, over controls without exposure.
