Figure 2

Characterisation of the mgo operon: A) diagram of the location of the amplified region obtained during the RT-PCR experiments. The molecular size and gel lanes are indicated. Lanes 2 and 5 have two molecular sizes: lane 2 shows 306 bp, and line 5 shows 360 bp in section B; lane 2 shows 401 bp and lane 5 shows 568 bp in section C. The putative mgo operon involved in mangotoxin production by Pseudomonas syringae pv. syringae UMAF0158 is illustrated by grey boxes, and the upstream ORF is indicated by a white box. Each gene studied in this study was given a specific name. B) The PCR products obtained from the RT-PCR experiments that used as templates genomic DNA and mRNA derived from wild-type UMAF0158 after 48 h of incubation at 22°C on liquid PMS minimal medium. C) The PCR products obtained from the RT-PCR experiments using mRNA from the insertional mutants UMAF0158::mgoB and UMAF0158::mgoC. HyperLadder IV (Bioline) were subjected to agarose electrophoresis. D) The Northern blot analysis of the total mRNA obtained from wild-type UMAF0158 and the insertional mutants using a fraction of the mgoC gene as a probe. Lane L, ssRNA ladder; lane 1, UMAF0158; lane 2, UMAF0158::mgoB and lane 3, UMAF0158::mgoC.
