Conyza canadensis from Jordan: Phytochemical Profiling, Antioxidant, and Antimicrobial Activity Evaluation. [PDF]
MoleculesIn this investigation, the chemical composition of the hydro-distilled essential oil (HD-EO), obtained from the fresh aerial parts (inflorescence heads (Inf), leaves (L), and stems (St)) of Conyza canadensis growing wild in Jordan was determined by GC/MS. Additionally, the methanolic extract obtained from the whole aerial parts of C.

Arbuscular mycorrhiza can be disadvantageous for weedy annuals in competition with paired perennial plants [PDF]
Scientific Reports, 2022 Arbuscular mycorrhizal (AM) fungi can support the establishment of mycotrophic plants in new environments. However, the role of mycorrhizal symbiosis in interactions between perennial and weedy annual plants is not well understood.

Functional synergy and genomic linkage of glyphosate resistance traits in Canada fleabane. [PDF]
Pest Manag SciStacking target‐site and non‐target‐site glyphosate resistance mechanisms in Conyza canadensis results in strong synergistic effects. This study quantifies gene × gene interactions and maps linked resistance loci, advancing our understanding of herbicide resistance genetics and informing management strategies.

Invasive plants optimize leaf nitrogen allocation in photosynthesis. [PDF]
New PhytolSummary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.
