Motifs of the V1, V3 or V6 hypervariable regions found in at least two r-clusters.

aThe letters correspond to the aeruginosa (A), fluorescens (F) and putida (P) r-clusters.bThis V3 motif was found in the minor allele (allele a) of the 16S rRNA gene in the MFY30 strain.a 上述字母分别对应铜绿假单胞菌（aeruginosa）、荧光假单胞菌（fluorescens）与恶臭假单胞菌（putida）的r簇（r-clusters）。 b 该V3基序（V3 motif）存在于MFY30菌株16S核糖体RNA基因（16S rRNA gene）的次要等位基因（等位基因a）中。
