Figure 1. Map of three EPSPS haplotypes in glyphosate-resistant
kochia (Bassia scoparia). 1) increased EPSPS copy number,
presence of type I and II repeats, MGE ≥ 10 (Central Great Plains); 2)
increased EPSPS copy number, no Type I or II, MGE ≥ 10 (Northern
Plains); 3) increased EPSPS copy number, no Type I or II, MGE
< 10 (Pacific Northwest, some Wyoming). Figure legend created
using BioRender.
Figure 2. Population level phylogeny tree in
glyphosate-resistant kochia (Bassia scoparia). Forty-four kochia
populations are included in this analysis. The neighbor-joining tree is
based on Prevosti’s distance. Bootstrap values (%) are shown if
>20% and are based on 1000 replicates.
Glyphosate-resistant, (R) and -susceptible (S); CGP1, Central Great
Plains (green square with diagonal lines); NP2, Northern Plains (yellow
square with vertical lines); PNW3, Pacific Northwest (blue square with
horizontal lines).
Figure 3. Bayesian clustering analysis (STRUCTURE) in
glyphosate-resistant kochia (Bassia scoparia). Assignment of 509
kochia individuals from 44 populations to the K=3 genetic clusters
inferred by analysis. Populations are sorted by region (Central Great
Plains, Northern Plains, and Pacific Northwest) and alphabetized within
region. Each horizontal bar corresponds to a distinct individual and its
probability of assignment, q , to each cluster.
