Soil phosphate availability drives shifts between arbuscular mycorrhizal and ectomycorrhizal fungi in the dual mycorrhizal plant Quercus serrata

Dual mycorrhizal plants are associated with both arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) fungi that differ in cost and effectiveness for nutrient acquisition. Little is known about env.....

Drought mitigation in plants through root exudate-mediated rhizosphere interactions: Opportunities for future research - ScienceDirect

•The study showed the role of root exudate in drought stress mitigation. •In drought conditions, increased naringenin and daidzein in exudates to attract diazotrophic bacteria. •Proteoid roots enhance surface area, carboxylic acid release, and phosphorus uptake in drought conditions. •The HvAACT1 gene aids citrate exudation at root apex, boosting elongation of root in drought conditions. •This study is useful in formulating strategies for sustainable environment management.
