We plan to do wet lab modelling. By tagging our microbes with simple GFP constructs and taking in vivo measurments of fluorescence levels, we hope to be able to estimate nutrient or RNAi levels produced within eukaryotic hosts. More to come as this develops.

In corn, we are doing this using a corn endophyte called Klebsiella pneumonii. Plants were either injected with 5 ul of bacterial suspension or dipped in it at an early stage. Two weeks later (a month for the dipped plants) 500 mg of tissue were harvested, ground in sterilized mortars, resuspended in 500 ul of sodium phosphate buffer, and 50 ul of the dilution was spread on half of a kanamycin LB plate.  The results are depicted graphically below.

Making projections based on measurements on endosymbiont and endophyte numbers within a functioning biological system using GFP


We plan to do wet lab modelling. By tagging our microbes with simple GFP constructs and counting colony forming units per set sample fresh weight, we hope to be able to observe microbial survival with our construct and predict how much beta carotene or RNAi might be produced and released.

In corn, we are doing this using a corn endophyte called Klebsiella pneumonii. Plants were either injected with 5 ul of bacterial suspension or dipped in it at an early stage. Two weeks later (a month for the dipped plants) 500 mg of tissue were harvested, ground in sterilized mortars, resuspended in 500 ul of sodium phosphate buffer, and 50 ul of the dilution was spread on half of a kanamycin LB plate. The results are depicted graphically below.
