Figure 2

Map showing ___location of Conyza biotypes and accessions in this study and the presence or absence of the Pro-106-Ser mutation. White markers indicate biotypes and accessions with the Pro-106-Ser mutation, and black markers indicate those without the Pro-106-Ser mutation. Glyphosate resistance categories based on 80% survival at 0×(susceptible, S), 1×(R1), 8×(R2), 20×(R3), and 40×(R4). See Supplemental Table 1 for GPS locations for each biotype or accession.
