Sample distribution of ' Candidatus Liberibacter asiaticus' from 15 citrus-growing counties (gray highlighted) in Florida, USA. Green circles indicate the counties where only the dominant 'Ca. L. asiaticus' group were observed based on STRUCTURE analysis (green in Figure 2). Some isolates from Polk County (13), Pasco County (14) and Lake County (15) were included with the genetic group 2 (less dominant group) (see Figure 2).
