An “omic” approach towards molecular diagnosis of resistance to auxinic herbicides in Corn poppy (Papaver rhoeas)
2021
National audience; Papaver rhoeas (corn poppy) is a major, troublesome weed in winter crops. In conventionalagriculture, poppy control is essentially achieved through herbicide application. Followingintensive use of these substances, resistance has evolved in many poppy populations across itsrange in Europe. Among the herbicide modes of action concerned by resistance are auxinmimeticherbicides (HRAC group 4/O). Resistance to this mode of action has little beeninvestigated, and its determinants remain largely unknown. Literature data suggests that, whiletarget-site-based resistance exist, non-target-site-based resistance mechanisms may bepredominant. Target-site-based resistance to auxinic h…
Occurrence of non-target-site-based resistance to ALS inhibitors in the broadleaf weed Papaver rhoeas (corn poppy).
2013
The vast majority of reported cases of resistance to ALS inhibitors in broadleaves is due to the selection of mutant, herbicide-resistant ALS alleles carrying a mutation at one of a few ALS codons that can be easily identified (ALS-based resistance). Non-ALS-based resistance (non-target-site resistance, NTSR), considered to be endowed by differences in the expression of many genes, has essentially been reported in grasses and hardly ever in broadleaves. We investigated NTSR to ALS inhibitors in poppy by pairing plants resistant to ALS inhibitors with susceptible plants and subsequently analysing the segregation of resistance in F1 families. Poppy plants resistant to ALS inhibitors were geno…
Groupe de travail COLUMA Bourgogne Franche-Comté : analyse et cartographie de la résistance aux herbicides sur céréales
2013
This working group made a survey and drew maps of herbicide resistances in cereal crops according to modes of action and weed species. These resistances concern mainly grass weeds but also one dicot weeds.
