Non-target-site-based resistance to herbicides: what do we know, and how can we know more?
2013
Non-target-site-based resistance (NTSR) includes all types of mechanisms conferring resistance to herbicides that do not involve modifications at the herbicide target site. NTSR can be the most widespread type of resistance in a weed species, especially in grasses. NTSR can confer resistance to herbicides with different modes of action. Despite the threat it sets upon chemical weed control, NTSR is still the dark side of resistance to herbicides. In particular, NTSR genetics is poorly known. As a consequence, there are no quick, molecular-based, NTSR diagnostic tools, which hampers the development of tactics aiming at delaying NTSR selection in the field. The lack of data regarding NTSR gen…
Identification de gènes liés à la résistance aux herbicides non liée à la cible chez les Ivraies : vers des tests « moléculaires » de diagnostic
2016
Identification of genes linked to non-target-site resistance to herbicides in ryegrass : towards "molecular" diagnosis assays. Setting up molecular diagnosis tools would greatly foster preventing and managing non-target-sitebased resistance to herbicides (NTSR). This is currently hampered by the complexity of NTSR genetic determinism, which is largely based upon differences in the expression of an unknown number of genes between resistant and sensitive plants. Identifying NTSR genes is thus a challenging task. Herein, we report the identification of 19 genes which expression patterns are correlated to NTSR to ALS-inhibiting herbicides in rye-grasses (Lolium sp.). We demonstrate the potentia…
