B31C:
Exploring Plant Genotypic Diversity in Rhizosphere Engineering Posters

Submit an Abstract to this Session



Session ID#: 24474

Session Description:
The rhizosphere is arguably the most complex microbial habitat on earth, comprising an integrated network of plant roots, the soil and diverse microbial consortia. Understanding, predicting and controlling the structure and function of the rhizosphere will allow us to harness rhizosphere activities as a means to increase or restore plant ecosystem services, e.g. crop production and soil carbon storage. Exploring plant genotypic diversity for traits such as carbon allocation, root system architecture and root exudate chemistry will put us in position to define and utilize plant ideotypes for specified outcomes in current or simulated future biogeographical environments. Targeted plant traits can be further enhanced by synthetic biology or transgenic approaches. We invite presentations that highlight studies aimed at improving our understanding of genotypic diversity for plant functional traits and how this knowledge can be exploited in rhizosphere engineering. Focus on model systems, bioenergy cropping systems or native grasslands are welcome.
