Summary This account presents information on all aspects of the biology Ambrosia artemisiifolia L. (Common ragweed) that are relevant to understanding its ecology. The main topics presented within standard framework Biological Flora British Isles : distribution, habitat, communities, responses biotic factors, environment, structure and physiology, phenology, floral seed characters, herbivores disease, history, conservation, impacts management. is a monoecious, wind‐pollinated, annual herb...
Abstract Aim The problems in public health and field management France caused by Ambrosia artemisiifolia L. require a better knowledge of the introduction naturalization this species both past present. Location France. Methods pattern spread A. was investigated through study herbarium specimens. More than 1200 specimens were found 58 herbaria virtual bordering countries. analysed mapping localities for each 30‐year period since 1863. Specific indications as ‘new plant’ used to determine...
Summary Pleiotropic effects associated with genes endowing resistance to herbicides are generally predicted reduce plant fitness. Quantifying these is necessary develop management strategies against herbicide‐resistant weeds. We assessed the pleiotropic three mutant alleles of herbicide target enzyme acetyl‐coenzyme A carboxylase (ACCase) on growth and seed production in black‐grass Alopecurus myosuroides . In each two field experiments, populations segregating for Leu‐1781 (five...
• The geographical structure of resistance to herbicides inhibiting acetyl-coenzyme A carboxylase (ACCase) was investigated in the weed Alopecurus myosuroides (black-grass) across its range gain insight into process plant adaptation response anthropogenic selective pressures occurring agricultural ecosystems. We analysed 297 populations distributed six countries A. myosuroides' main area occupancy. frequencies plants resistant two broadly used ACCase inhibitors and seven mutant, alleles were...

Weed Research 51 , 433–437. Summary (NTSR) mechanisms can confer unpredictable to herbicides with different chemistries or modes action. In two French fields, 18% and 40% individual plants (black‐grass), respectively, were resistant via NTSR all most effective approved A. control in wheat...
Invasive species are a key driver of the global biodiversity crisis, but drivers invasiveness, including role pathogens, remain debated. We investigated genomic basis invasiveness in Ambrosia artemisiifolia (common ragweed), introduced to Europe late 19th century, by resequencing 655 ragweed genomes, 308 herbarium specimens collected up 190 years ago. In invasive European populations, we found selection signatures defense genes and lower prevalence disease-inducing plant pathogens. Together...
Background and Aims:Ambrosia artemisiifolia is a ruderal weed introduced from North America to Europe. It produces large amount of achenes which are highly heterogeneous in size. Due the preponderant role propagules invasive plant processes, achene mass variability related germination, dispersal strategy life history traits offspring were investigated within this species.
Abstract Questions: What are the relationships between weed species traits and their change in distribution over a 30‐year period? does it tell us about factors that have driven shifts composition of communities? Location: France. Methods: We analysed links status sunflower crops (decreasing or increasing) set 17 using data sets collected 1970s 2000s, respectively. contribution to explain changes both individually multivariate way by mean clustering into functional groups. Results: 69% most...
Summary We assessed the contributions of target site‐ and non‐target site‐based resistance to herbicides inhibiting acetyl‐coenzyme A carboxylase (ACC) in Alopecurus myosuroides (black grass). total 243 A. populations collected across France were analysed using herbicide sensitivity bioassay (24 300 seedlings analysed) ACC genotyping (13 188 analysed). Seedlings resistant at least one ACC‐inhibiting detected 99.2% populations. Mutant, allele(s) 56.8% Among five alleles known , containing an...
Acetyl-CoA carboxylase (ACCase) alleles carrying one point mutation that confers resistance to herbicides have been identified in arable grass weed populations where has evolved under the selective pressure of herbicides. In an effort determine whether herbicide evolves from newly arisen mutations or standing genetic variation populations, we used herbarium specimens Alopecurus myosuroides seek mutant ACCase isoleucine-to-leucine substitution at codon 1781 endows resistance. These had...
Abstract The weed soil seedbank is of interest in agroecosystems as a major source infestation fields and reservoir plant seed‐feeder diversity. A characteristic annual plants has been the focus numerous studies, it reflects past aboveground vegetation future vegetation. Therefore, potentially can be used to evaluate past, present communities. goal this paper was provide guidelines help researchers do survey. Through qualitative review 60 articles, we investigate why how studied agronomy. It...
