Real-time PCR analysis of genes involved in biofilm formation and degradation of nutrients. B. subtilis OKB105 cells were harvested at different times during interaction with rice seedlings (15 min, 30 min, 1 h, 2 h, 4 h, 6 h, 8 h, 10 h and 12 h) for extracting total RNA. The gene galE encoding UDP-glucose-4-epimerase, ywkA encoding malate dehydrogenase and araA encoding L-arabinose isomerase were identified, and are known to be involved in nutrient degradation. TasA encoding major a biofilm matrix component, srfAA encoding surfactin synthetase, and sinI encoding antagonist of SinR were also identified, and are involved in biofilm formation.
