Developmental constraint underlies the replicated evolution of grass awns. [PDF]
New PhytolSummary Replicated trait evolution can provide insights into the mechanisms underlying the evolution of biodiversity. One example of replicated evolution is the awn, an organ elaboration in grass inflorescences. Awns are likely homologous to leaf blades.

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism. [PDF]
Plant DirectABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.

The genetic architecture and spatiotemporal dynamics of adaptation across human-modified landscapes. [PDF]
New PhytolSummary Understanding the rate and nature of adaptation is crucial for managing biodiversity across our changing landscapes. This perspective synthesizes insights from resistance evolution – a case of rapid, repeated adaptation to extreme human‐mediated selection – to reveal how adaptive genetic architectures determine and feedback with evolutionary ...

The continuing significance of chiral agrochemicals. [PDF]
Pest Manag SciIn the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Plant, Soil and Environment, 2023 Changing political demands requires the search for alternatives to glyphosate, which has often been used in the stale seedbed method. In three field trials between 2020 and 2023, three electrophysical treatments (XPower System, Zasso®) differing in speed,

Julius-Kühn-Archiv, 2022 The herbicide flufenacet, applied in pre-emergence, acts as an inhibitor of the synthesis of very long-chain fatty acids (HRAC group 15) and is an important component in the control of grasses in winter cereals, especially when resistance to other ...

Deep haplotype analyses of target-site resistance locus ACCase in blackgrass enabled by pool-based amplicon sequencing. [PDF]
Plant Biotechnol J, 2023 Summary Rapid adaptation of weeds to herbicide applications in agriculture through resistance development is a widespread phenomenon. In particular, the grass Alopecurus myosuroides is an extremely problematic weed in cereal crops with the potential to manifest resistance in

Agronomy, 2022 Cinmethylin, a pre-emergent applied active ingredient, inhibits the fatty acid thioesterase and offers a new option in the chemical control of Alopecurus myosuroides, one of the most problematic weeds in arable farming in Europe. It was assumed that with
