Resistance to Disease • Design an experiment
Biological Samples • Resistant variety vs Susceptible variety • Resistant variety, following infection. • Resistant soybean, infective/non infective pathogen
Plant selection • From where would the plants come? • Lighting conditions • Plant varieties • Temperature
Cy3/Cy5 • Channel variability? • Depends on what sort of experiment we do. Time courses will be single colour.
Infective Process • Different amounts of infection • Different strains of pathogen
With array variability • Printing Defects • Hybridisation defects • Probe strengths
Between arrays • Different conditions for hybridisation • Different detection machines
