Utilisation de la PCR-RFLP sur de l'ADN chloro-plastique pour l'étude des relations phylogénétiques au sein du genre Phaseolus [PDF]

Biotechnologie, Agronomie, Société et Environnement, 1998
Phylogenetic relationships among 74 accessions belonging to six species of Phaseolus are investigated using variation in chloroplast DNA assessed according to a PCR-RFLP protocol. Three fragments of chloroplast DNA are amplified using universal primers,

Predator cues from jumping spiders modulate herbivore behaviour and reduce plant damage

Ecological Entomology, EarlyView.
Jumping spider cues increase immobility and delay first reproduction in the aphid Myzus persicae. Spider cues reduce leaf consumption by chewing herbivores, indicating reduced herbivore pressure on plants. Jumping spider cues may mediate indirect effects across trophic levels by altering herbivore behaviour and plant–herbivore interactions.

Improving Decision‐Making in the Identification of Tephritidae Larvae at Import in the European Union and Key to Third Instar Larvae

Journal of Applied Entomology, EarlyView.
ABSTRACT The Tephritidae family, or true fruit flies, comprises approximately 250 species recognized as economically significant due to their capacity to infest commercial fruits. These pests pose serious threats to both food security and trade, and are considered quarantine pests in areas where they are not yet established. In the European Union (EU),

Can Soil‐Dwelling Predatory Mites Control the Invasive Thrips Species Thrips parvispinus?

Journal of Applied Entomology, EarlyView.
ABSTRACT Thrips parvispinus (Karny) has recently become an important invasive thrips in crops world‐wide. It is highly polyphagous and a threat to both ornamental and vegetable crops. Often, new pests are controlled with chemical pesticides, but sustainable options such as biological control are in increasing demand as alternatives.

Cytokinins Promote Rust Susceptibility in Poplar by Suppressing Defence Signalling, Reducing Defence Accumulation and Reprogramming Primary Metabolism

Plant, Cell &Environment, EarlyView.
ABSTRACT Cytokinins (CKs), classically recognised as plant growth regulators, are increasingly implicated in plant‐microbe interactions. Studies in herbaceous plants suggest that CKs can function as signalling molecules with dual roles in plant defence, either restricting or facilitating pathogen infection.
