From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

Ecological Entomology, EarlyView.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

Feeding Preference and Foraging Behaviour of Eriopis connexa on Two Aphid Species

Journal of Applied Entomology, EarlyView.
ABSTRACT Aphids are phloem‐feeding insects that cause both direct and indirect damage to crops, reducing agricultural productivity. Among the available pest control strategies, biological control using natural enemies is a sustainable and effective approach. The ladybird Eriopis connexa (Germar, 1824) is a generalist predator known for its voracity and

A natural variation within duplicated AsWRKY49‐D2 drives the subgenomic functional divergence of homeologs in salt response of allohexaploid oats

Journal of Integrative Plant Biology, EarlyView.
Transcriptome analysis of oats under salt stress identified ten important salt‐responsive transcription factor families, which show extensive functional divergence among three oat subgenomes. Further integration with a genome‐wide association study under salt stress identified the AsWRKY49‐D2 gene, whose elite haplotype holds substantial potential for ...

The maize mitogen‐activated protein kinase kinase kinase gene ZmMAPKKK45 is associated with multiple disease resistance

New Phytologist, EarlyView.
Summary Southern leaf blight (SLB), caused by the necrotrophic fungus Cochliobolus heterostrophus, is a major foliar disease of maize (Zea mays) world‐wide. A genome‐wide association study was performed to dissect the genetic basis of SLB resistance in maize. Functional validation was performed using mutant and transgenic analyses.
