Bactericidal activity of the chloroplast-produced Pal and Cpl-1 proteins on S. pneumoniae cultures. (A) Time course of bacterial cell death as monitored by clearing of bacterial cultures. The amounts of total soluble plant protein added to the cultures at time point 0 are indicated. The OD of the cultures was measured at 600 nm (OD₆₀₀). Data are from 2 sets of experiments with 3 replicas each. The standard deviation is indicated. (B) Synergistic action of Pal and Cpl-1 in bacterial killing assays is shown.
