Figure 1From: Housekeeping genes essential for pantothenate biosynthesis are plasmid-encoded in Rhizobium etli and Rhizobium leguminosarumPantothenate auxotrophy of R. etli CFN42 panC and panB mutants. Growth of the R. etli CFN42 wild-type strain and its derivative panC (ReTV1) and panB (ReTV2) mutants in: (a) minimal medium, (b) minimal medium supplemented with 1 μM calcium pantothenate. Values represent the means of three independent experiments; error bars show standard deviations.Back to article page
