Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Effect of Direct Contact on the Phytotoxicity of Silver Nanomaterials

, 2016
The increasing use of silver nanomaterials (AgNMs) in consumer products will result in an increased amount entering the environment, where AgNMs were recently found to cause phytotoxicity in the model plant Lolium multiflorum.

Comparing verbenone‐based repellents for ambrosia beetle management in eastern apple orchards

Agricultural and Forest Entomology, EarlyView.
Non‐native ambrosia beetles (Xylosandrus germanus, X. crassiusculus, Anisandrus maiche) damage high‐density apple orchards across the eastern United States, motivating the search for selective, semiochemical‐based repellent strategies. Across Ohio, New York and Pennsylvania, three verbenone formulations, sachets, SPLAT® VERB and a test SPLAT ...

Multiomics Analysis of the Mechanism by Which Gibberellin Alleviates S-Metolachlor Toxicity in Rice Seedlings

Plants
S-metolachlor is a selective pre-emergence herbicide used in dryland. However, it is challenging to employ in paddy fields due to its phytotoxic effects on rice.

Surfactant-Induced Phytotoxicity

, 1994
The leaves of tall morningglory, giant duckweed, and common purslane were treated with nine surfactants at a concentration of 0.1% and examined after 24 hr using cryo-scanning electron microscopy for phytotoxicity as evidenced by tissue damage and ...

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Knowledge Work as a Condition of Accumulation in the Pesticide Industry: Syngenta's Defence of Paraquat

Journal of Agrarian Change, EarlyView.
ABSTRACT What do pesticide companies do to keep their products on the market despite strong societal and scientific critiques of their environmental and health risks? This paper examines the herbicide paraquat, one of the most controversial pesticides, from the early 1960s to the present.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...
