Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

Pest Management Science, EarlyView.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

Pest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

Effects of Epichloë festucae var. lolii on heavy metal stress tolerance of its perennial ryegrass host

Grassland Research
Background The endophyte Epichloë festucae var. lolii forms mutualistic symbiosis with perennial ryegrass, and their relationship under heavy metal stress needs to be more clearly defined. Methods This study assessed the growth and physiological response

Pro‐197 mutations confer resistance to thiencarbazone but not to foramsulfuron in ALS‐resistant Poa annua populations

Pest Management Science, EarlyView.
Foramsulfuron remains effective on Pro‐197 Poa annua, but co‐formulation with thiencarbazone reduces efficacy due to limited activity and antagonism. Therefore, foramsulfuron + thiencarbazone should be used in fields without ALS‐resistant weeds to ensure effective in‐crop control.

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Dietary preference of sheep for perennial ryegrass and white clover at contrasting sward surface heights

, 2000
Non-pregnant, non-lactating ewes grazed adjacent monocultures of white clover and perennial ryegrass with three sward surface height (SSH) combinations [6 cm white clover: 6 cm perennial ryegrass (c6gG), 3 cm white clover: 6 cm perennial ryegrass (c3g6),

Low pyrrolizidine alkaloid levels in perennial ryegrass is associated with the absence of a homospermidine synthase gene

BMC Plant Biology, 2018
Background Pyrrolizidine alkaloids (PAs) are a class of secondary metabolites that function as feeding deterrents in a range of different plant species.

A Meta‐Analysis Reveals That the Protective Role of Silicon in Grasses Against Fungal Pathogens Depends on Infection Mechanism

Plant, Cell &Environment, EarlyView.
ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

Effect of ryegrass endophyte in mixed swards of perennial ryegrass and white clover under two levels of irrigation and pesticide treatment

, 1992
In a small-plot experiment at Hurley, UK, infection of perennial ryegrass with the endophytic fungus Acremonium lolii had no apparent effect on seedling populations and herbage yield of ryegrass and white clover sown in mixture. The plots were maintained
