Project description

  • We aim to reveal novel bacteria by plant host-selection for boosting productivity of bio-fertilizer for sustainable agriculture.
     

  • We apply novel culture-independent approach and characterize plant response to bacterial inoculants. Which are amended to the roots, for screening in planta and under greenhouse condition (Multi-seasonal trials).

Bacteria characterization and isolation process

324 cell growth tray with plants about to be amended with bacterial isolates. Each plant is separated by Styrofoam squared cells. A line of untreated plants is planted to avoid cross contamination. Each tray can used for up to 25 randomly assigned bacterial isolates.

The Rhizosphere accommodates 10-100 time more bacteria in comparison to non-rhizospheric soil. It contains a rich interaction and communication network the exhibits strong plant microbe and microbe-microbe relationships (1). Bacteria were isolated from tomato roots with plant derived media (2) and are screened in planta by inoculating roots and growing for a test period (3)
