Comparison of expression ratios based on microarray- and qPCR- data. Array data: more than 15× higher expressed in toxic strains, ++; more than 5×, +; more than 5× higher expressed in non-toxic strain, -; 2-5× higher expressed in non-toxic strain, (-); raw data see supplementary table 1. qPCR: Ct < 25, ++; Ct<27, +; Ct>27, -; N.D., not detected at Ct < 35.
