TLDR
It is demonstrated that the simple isoflavones daidzein and genistein, which occur in soybean root exudates, are highly effective chemoattractants for zoospores of Phytophthora sojae, an economically important pathogen of soybeans.About:

The rhizosphere microbiome: significance of plant beneficial, plant pathogenic, and human pathogenic microorganisms
TL;DR: The main functions of rhizosphere microorganisms and how they impact on health and disease are reviewed and several strategies to redirect or reshape the rhizospheric microbiome in favor of microorganisms that are beneficial to plant growth and health are highlighted.

TL;DR: Comparison of the two species' genomes reveals a rapid expansion and diversification of many protein families associated with plant infection such as hydrolases, ABC transporters, protein toxins, proteinase inhibitors, and, in particular, a superfamily of 700 proteins with similarity to known oömycete avirulence genes.

Biological Control of Plant Pathogens
TL;DR: Some pest management researchers have focused their efforts on developing alternative inputs to synthetic chemicals for controlling pests and diseases, among these alternatives are those referred to as biological controls.

Rhizosphere carbon flow in trees, in comparison with annual plants: the importance of root exudation and its impact on microbial activity and nutrient availability
TL;DR: It is demonstrated that root exudates are an important component of carbon loss from plants and that they may have a more important role in nutrient acquisition and plant growth than previously thought.

Rhizobium-legume nodulation: life together in the underground.
TL;DR: This review concerns a dramatic association, one of the few that has been studied in detail: the nitrogen fixing symbiosis between certain plants and microbes Rhizobium bacteria stimulate leguminous plants to develop root nodules, which the bacteria infect and inhabit.

Induction of Bradyrhizobium japonicum common nod genes by isoflavones isolated from Glycine max
TL;DR: A broad-host-range plasmid containing a Bradyrhizobium japonicum nodDABC-lacZ translational fusion was constructed and used to monitor nod gene expression in response to soybean root extract, and the specificity of induction appears to be influenced by the host-strain genome.

Flavonoid and isoflavonoid distribution in developing soybean seedling tissues and in seed and root exudates.
TL;DR: Analysis of seed exudates suggests that this is a continuous, but saturable event; in the dark, isoflavone levels in the root tips are greatly reduced, while those in the cotyledons are higher.

Factors affecting glucosidase and galactosidase activities in soils
F. Eivazi,M. A. Tabatabai +1 more
TL;DR: In this paper, the effects of soil treatments, the addition of 12 inorganic salts and of 20 trace elements on α- and β-glucosidase and α-and β-galactosidases activities in soils were investigated.
