Genetic determinisms, evolution and detection of non-target-site based resistance to herbicides inhibiting acetolactate-synthase in rye-grass (Lolium…
2016
The aim of this study is to unravel the genetic determinism of non-target-site resistance (NTSR) to herbicides inhibiting acetolactate-synthase (ALS) in the major weed rye-grass (Lolium sp.), and to estimate the feasibility of NTSR diagnosis based on genetic data. On the one hand, this work contributes to the understanding of the processes driving the evolution of NTSR to herbicides, and on the other hand it lays the foundations for the development of a diagnosis tool to identify NTSR to ALS inhibiting herbicides. - Using a quantitative transcriptome sequencing approach, we showed that NTSR evolve by recurrent selection of higher and higher constitutive expression levels of genes involved i…
Status of herbicide-resistant Lolium populations in wheat fields in Tunisia
2013
The evolution of herbicide resistance in weeds is a worldwide phenomenon in modern cropping systems. The presence of resistant populations can severely hamper herbicide-based weed control, thus leading to the need for a more accurate use of these products. In Tunisia, the first report of evolved herbicide resistance concerned Lolium rigidum populations collected in wheat fields in northern Tunisia in 1996 and found to be resistant to acetyl-coenzyme A carboxylase-inhibiting (ACCase) herbicides. The objective of this study is to detect and characterise herbicide resistance in ryegrass (Lolium spp). The sensitivity of nine ryegrass populations, collected in wheat fields in northern Tunisia, w…
