Root-rhizosphere interactions and modifications
MetadataShow full item record
The interactions between the plant and rhizosphere are complex, but recent research is elucidating more about a diverse array of relationships. In response to the growing demand for natural or plant produced pesticides and herbicides, a novel method for the identification of bioactive root exudates was developed utilizing the hypothesis that exudate compounds changing in relative abundance over plant development were likely bioactive. Research investigated this hypothesis on Arabidopsis grown in vitro and then in maize grown under greenhouse conditions. Four compounds were identified as bioactive, ...
