Fig 2.

Plant phenotypes exhibited by putative Tat substrate deletions. Shown are plant dry weights of alfalfa (black bars) or sweet clover (white bars) inoculated with the strain indicated. The data represent between 4 and 6 independent experiments, each consisting of 30 plants, and are presented as percentages of the wild type. Wild-type plant weights (100%) were 57 ± 6 mg/plant (alfalfa, n = 6) and 85 ± 11 mg/plant (sweet clover, n = 6). Differences between the plants inoculated with mutant and the wild type are based on Student's t test at the 95% confidence level (P < 0.0001).
