Genetic basis and origin of resistance to acetolactate synthase inhibitors in Amaranthus palmeri from Spain and Italy

BACKGROUND:Amaranthus palmeriis an aggressive annual weed native to the United States, which has become invasive insome European countries. Populations resistant to acetolactate synthase (ALS) inhibitors have been recorded in Spain andItaly, but the evolutionary origin of the resistance traits remai...

Populations resistant to acetolactate synthase (ALS) inhibitors have been recorded in Spain andItaly, but the evolutionary origin of the resistance traits remains unknown. Bioassays were conducted to identify cross-resistance to ALS inhibitors and a haplotype-based genetic approach was used to elucidate the origin and distribution of resis-tance in both countries.RESULTS:Amaranthus palmeripopulations were resistant to thifensulfuron-methyl and imazamox, and the 574-Leu mutantALSallele was found to be the main cause of resistance among them. In two Spanish populations, 376-Glu and 197-Thr mutantALSalleles were also found. The haplotype analyses revealed the presence of two and four distinct 574-Leu mutant haplotypes inthe Italian and Spanish populations, respectively. None was common to both countries, but some mutant haplotypes wereshared between geographically close populations or between populations more than 100 km apart. Wide genetic diversitywas found in two very close Spanish populations.CONCLUSION: ALS-resistantA. palmeripopulations were introduced to Italy and Spain from outside Europe. Populations fromboth countries have different evolutionary histories and originate from independent introduction events. ALS resistance thenspread over short and long distances by seed dispersal. The higher number and genetic diversity among mutant haplotypesfrom the Spanish populations indicated recurrent invasions. The implementation of control tactics to limit seed dispersaland the establishment ofA. palmeriis recommended in both countries.This work was supported by the Spanish State Research Agency, Spain (AEI) and the European Regional Development Fund, EU (ERDF) through the project PID2020‐113229RB‐C42.
