| Abstract/Contents: | "Poa annua L., or annual bluegrass, is a common weed in turfgrass. P. annua has been found resistant to nine different herbicide modes of action and some cases of multiple resistances within the same population. In an effort to quantify the spread of herbicide resistant P. annua across the country, the ResistPoa Project (http://resistpoa.org) surveyed 1367 P. annua populations for resistance to nine modes of action and a single fungicide. Herein we report results from sequencing of known target site mutations found in EPSPS, ALS, psbA, and ??- tubulin genes. Populations were sequenced using either capillary or amplicon sequencing (AmpSeq), depending on the complexity of the gene, and analyzed for target site resistance. 463 suspected resistant populations were sequenced, of which 131 for ALS, 84 for EPSPS, 93 for psbA, and 78 for ??-tubulin. 77 of these populations also displayed resistance to multiple modes of action. Of these populations, 65.6% of ALS, 73.8% of EPSPS, 38.7%% of psbA, 97.4% of ??- tubulin, and 44.2% of populations with multiple resistances presented with a target site mutation at the Trp574, Pro106, Ser264, and Thr239 sites respectively." |
