We describe a method of inducing hairy roots by Agrobacterium rhizogenes-mediated transformation in Tartary buckwheat (Fagopyrum tataricum). This can be used to investigate gene functions and production of secondary metabolites in Tartary buckwheat, be adopted for any genetic transformation, or used for other medicinal plants after improvement.

Network analysis was applied to evaluate the association of various ecological microbial communities, such as soil, water and rhizosphere. Presented here is a protocol on how to use the WGCNA algorithm to analyze different co-occurrence networks that may occur in the microbial communities due to different ecological environments.
