Role of luxS in Stress Tolerance and Adhesion Ability in Lactobacillus plantarum KLDS1.0391

Figure 3

PCR products of the luxS gene and its flanking regions (a) and morphological features of the Lactobacillus plantarum KLDS1.0391 luxS mutant (b) and wild-type strain (c) (×20,000). Lane 1: DL5000 DNA marker. Lane 2: luxS mutant strain. Lane 3: wild-type strain. The predicted sizes are as follows: flanking regions and the luxS gene of the wild-type strain, 2900 bp; the luxS deletion mutant, 3400 bp.
