Developmental constraint underlies the replicated evolution of grass awns. [PDF]

open access: yesNew Phytol
Summary 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.

Altered Translocation Pattern as Potential Glyphosate Resistance Mechanism in Blackgrass (Alopecurus myosuroides) Populations from Lower Saxony

open access: yesInternational Journal of Plant Biology
Glyphosate is a broad-spectrum herbicide widely used. After years of extensive usage, many weed species have developed resistance due to both target-site (TSR) and non-target-site resistance mechanisms (NTSRs).

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism. [PDF]

open access: yesPlant Direct
ABSTRACT 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]

open access: yesNew Phytol
Summary 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]

open access: yesPest Manag Sci
In 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.

Suppressing Alopecurus myosuroides in winter cereals by delayed sowing and pre-emergence herbicides

open access: yesPlant, Soil and Environment, 2022
Delayed sowing of winter cereals in Western Europe is a preventive method to reduce Alopecurus myosuroides infestations. Two series of on-farm studies including 36 experiments were conducted in South-Western Germany to analyse the combined effects of ...

The potential of glyphosate-alternatives like electrophysical weeding in the stale seedbed method for Alopecurus myosuroides (Huds.) control

open access: yesPlant, 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,

Multispectral Fine-Grained Classification of Blackgrass in Wheat and Barley Crops

open access: yesComputers and Electronics in Agriculture
As the burden of herbicide resistance grows and the environmental repercussions of excessive herbicide use become clear, new ways of managing weed populations are needed.

Investigation of glutathione transferases at the gene regulation level in flufenacet resistant black-grass populations (Alopecurus myosuroides Huds.)

open access: yesJulius-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 ...
