University of Kentucky Research Shows Microbially Derived Product Can Increase Plant Flavonoid and Lignin Content

University of Kentucky Blog ImageA study published in BMC Plant Biology demonstrated that SoilBuilder, a microbially derived soil additive, can increase the production of secondary metabolites in plants.

The study, which was conducted by researchers at the University of Kentucky, investigated how SoilBuilder application and timing of application (single or multiple times) influenced secondary metabolic responses by monitoring changes in the phenlypropanoid (PP) pathway in Arabidopsis thaliana.

Quantitative real-time PCR was used for transcriptional profiling of flavonoid and lignin pathway genes, and high performance liquid chromatography and liquid chromatography-electrospray ionization-quadrupole-time of flight-mass spectrometry were used to determine flavonoid content.

The results showed that application of SoilBuilder induced the phenlypropanoid pathway and there was a different response to treatment that was dependent on application timing. However, both single application and multiple applications of the microbial-derived product induced flavonoid and lignin content in Arabidopsis leaves compared to an untreated control.
