摘要：
We studied bacterial isolates 15M and 16M from calla lily tubers showing soft rot in commercial plantations in Poland. Colony morphology differed from that of known agents of bacterial soft rot of this plant. The use of Microgen Bacillus ID system allowed to identify both isolates as Paenibacillus polymyxa. This was confirmed by sequence analysis of 16S rRNA gene fragments. The isolates showed pectolytic activity on crystal violet pectate medium and on potato tubers. They caused strong soft rot on calla tubers and leaf petioles already 48 h after inoculation. Re-isolation of bacteria from rotted tissue confirmed their identity with those used for inoculation. This is the first report that P polymyxa can cause soft rot on calla lily.
