Disease development on Arabidopsis inoculated with B. cinerea. A, Four-week-old Arabidopsis plants were drop-inoculated with B. cinerea strain IMI169558, and photographs were taken 12 d later. Circles (heads of pipet tips) indicate positions of completely decayed plants. B, Decay of Arabidopsis plants drop-inoculated with B. cinerea strains IMI169558 and MUCL30158. The percentage of dead plants is expressed as a function of time after inoculation. Plants were considered dead when their hearts were completely rotten. Data represent averages ± se of three different experiments performed with 20 plants per genotype. Circles, Wild-type (Col-0) plants; squares, the mutant ein2-1; white symbols, plants inoculated with strain IMI169558; black symbols, plants inoculated with strain MUCL30158.
