Climate and the biotic community structure plant resistance across biogeographic groups of yellow monkeyflower

Ecology and Evolution, 2022
Characterizing correlates of phytochemical resistance trait variation across a landscape can provide insight into the ecological factors that have shaped the evolution of resistance arsenals.

Genome‐Wide Association Study Reveals Insect Genetics and Microbial Symbiont Effects on Susceptibility of Diaphorina citri to the Citrus Greening Pathogen, Candidatus Liberibacter Asiaticus

Advanced Science, EarlyView.
This study investigates the genetic and microbial factors influencing the susceptibility of Diaphorina citri to the citrus greening pathogen Candidatus Liberibacter asiaticus (CLas), employing a microbiome Genome Wide Association Study. The research identifies a key gene encoding an MFS‐type transporter contributing to CLas infectivity and abundance in

Sugar‐Armored Pesticides: Self‐Assembled System for Enhanced Foliar Adhesion and Sustained Delivery of Hydrophobic Antimicrobials Against Bacterial Diseases

Advanced Science, EarlyView.
This study develops a sugar‐armored, self‐assembled pesticide delivery system that enhances foliar adhesion, provides sustained release, effectively disrupts biofilms, and demonstrates superior bactericidal activity for improved disease control.

Linking Plant Metabolomics with Fungal Functional Dynamics Reveals a Noncanonical S‐R‐C Adaptive Trajectory

Advanced Science, EarlyView.
Using field‐based holo‐omics, we demonstrate that developmental shifts in sorghum leaf metabolomes drive a noncanonical fungal succession from stress tolerators (S) through ruderals (R) to competitors (C). Antifungal metabolites in young leaves select for S strategists with expanded genomes, transient maltose pulses during flowering favor fast‐growing ...

A native parasitic plant and soil microorganisms facilitate a native plant co‐occurrence with an invasive plant

Ecology and Evolution, 2019
Invasive plants often interact with antagonists that include native parasitic plants and pathogenic soil microbes, which may reduce fitness of the invaders. However, to date, most of the studies on the ecological consequences of antagonistic interactions

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Bacterial diet and weak cadmium stress affect the survivability of Caenorhabditis elegans and its resistance to severe stress

Heliyon, 2019
Stress may have negative or positive effects in dependence of its intensity (hormesis). We studied this phenomenon in Caenorhabditis elegans by applying weak or severe abiotic (cadmium, CdCl2) and/or biotic stress (different bacterial diets) during ...

Understanding Biotic Stress and Hormone Signalling in Cassava (Manihot esculenta): Potential for Using Hyphenated Analytical Techniques

Applied Sciences, 2020
Biotic stresses often constitute major factors limiting global crop yields. A better understanding of plant responses to these stresses will facilitate efforts to improve stress tolerance and yields, especially in a climatically changing world.

Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot

American Journal of Botany, EarlyView.
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

Invasive‐plant traits, native‐plant traits, and their divergences as invasion factors

Ecology and Evolution
Invasive plants exert significant ecological impacts on native plants, communities, and ecosystems. However, consistent conclusions regarding how traits of invasive plants, native plants, and their divergences affect invasion dynamics are still lacking ...
