The Daily Grind
- Innoculated corn in rhizosphere exiting experiment. Did two reps (two plants) per pDSK-GFPuv labelled bacteria, with JM109 as a negative control, and Kp342 as a positive control. Innoculum was 5 ul of OD600=0.2 suspension in sodium phosphate buffer, which was pipetted into a vertically cut hole in the stem as it poked out above the tube and parafilm lid. Plants were at the 4 leaf tip stage. As the droplet usually wasn't absorbed into the hole, plants were left lying vertically to dry the droplet off and avoid driping. Plants will be harvested for samples in 5 or 7 days. Plants were grown with 24 hr a day incandescent and flourescent light in a flow hood.
