Amino acid vectorization of salicylic acid enables efficient activation of NPR1‐dependent defense without phytotoxicity

Pest Management Science, EarlyView.
Amino acid‐vectorized salicylic acid activates PR1/NPR1‐dependent defenses without phytotoxicity, showing an efficient strategy for controlled delivery and enhanced plant immunity. Abstract BACKGROUND Addressing global food security under rapid population growth and climate change requires sustainable strategies to protect crops from pathogens while ...

Seed shattering in weedy rice is not similarly regulated as in cultivated rice.

, 2022
:Although seed shattering is one of the main causes of weedy rice persistence it still is poorly understood. The aim of this study was to identify the main genes related with the occurrence of seed shattering in weedy rice.

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.

Corn rootworm (Coleoptera: Chrysomelidae) emergence patterns, survival, and injury in blended refuges and pure stands of short‐stature corn and tall corn

Pest Management Science, EarlyView.
Graphical Abstract Text: This study compared corn rootworm (Diabrotica spp.) emergence patterns and injury between short‐stature corn and tall corn to help inform corn rootworm management strategies in short‐stature corn Abstract BACKGROUND Short‐stature corn became commercially available in the United States in 2025 and has several desirable qualities

Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

Pest Management Science, EarlyView.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

Competitive ability of cultivated rice MR219 and MR269 against weedy rice biotypes [PDF]

, 2016
An investigation to evaluate the competitive ability of MR219 and MR269 cultivated rice against three weedy rice biotypes viz: awn-spikelet (AWB), open panicle (OWB) and compact panicle (CWB) weedy rice biotypes was carried out in the greenhouse ...

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Variation in Oxidized Proanthocyanidins in Chinese Weedy Rice Seeds and Their Impact on Ecological Adaptation

Agronomy
Weedy rice, also known as red rice, mainly originates from the de-domestication of cultivated rice and is a vicious weed in paddy fields around the world. Its red seeds are rich in oxidized proanthocyanidins (OPAs).

Host‐associated chemical cues mediating host‐finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis

Pest Management Science, EarlyView.
Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...
