Figure 1: Differential display using total RNA from a wild-type strain AX2 and a mutant strain HG794 cells. Total RNA was prepared from cells developed for 3 h after starvation. 1,3, AX2; 2, HG794. Arrows indicate differential bands be- tween the wild-type strain AX2 and the mutant strain HG794. They were labeled as DD-3~-9, respectively. Combination of primers in each band: DD-3, T12MG/ AP11; DD-4, T12MG/AP17; DD-5, T12MA/AP5; DD-6, T12MC/AP5; DD-7, T12MG/ AP3; DD-8, T12MT/AP11; DD-9, T12MT/AP11.
