TL;DR: The data indicate that the introduction of the genetically modified derivative of 89B-27 did not pose a greater environmental risk than its unaltered wild type with respect to aerobic-heterotrophic bacterial community structure.

TL;DR: In this article, the authors proposed a method to increase the growth rate of seedlings in the soil or in the greenhouse, and produce seeds having a coating imparting resistance to disease, thereby decreasing the time required to produce transplants in seedling greenhouses prior to transplanting into agricultural fields; and develop "disease-suppressive" transplant plugs, which are protected for a time from multiple diseases through combined mechanisms of stimulated plant defense and increased activity of indigenous antagonistic microorganisms on plant roots.

TL;DR: These experiments show that the growth promotion effects by the tested PGPR/PGPB bacteria varied significantly between fresh and dry weights of shoot, root, and/or whole plant in the repeated greenhouse experiments, supporting the hypothesis that using fresh weight determination for assessing plant growth promotion by beneficial bacteria is inherently faulty.

TL;DR: The results indicate that the use of velvetbean in a cropping system alters the microbial communities of the rhizosphere and soil, and they are consistent with the hypothesis that the resulting control of nematodes results from induction of soil suppressiveness.
