Melting the wall: plant parasitism entails pectin modification

Plant Signaling & Behavior, 2023
Phtheirospermum japonicum shows induced expression of PjPME and PjPMEI genes during haustoria development in rice and Arabidopsis with increased PME activity, which leads to the modulated cell wall during parasitism.

The Survival and Parasitism Rate of Tamarixia radiata (Hymenoptera: Eulophidae) on Its Host Exposed to Beauveriabassiana (Ascomycota: Hypocreales)

Agronomy, 2021
The effect of the entomopathogenic fungus Beauveria bassiana (BB-12) on the biological characteristics of Tamarixia radiata parasitizing Diaphorina citri was studied under laboratory conditions.

Rare insights into intraspecific brood parasitism and apparent quasi–parasitism in black–capped chickadees

Animal Biodiversity and Conservation, 2011
Genetic analysis of passerine birds often finds evidence of extra–pair copulations within species, but genetic evidence of intraspecific brood parasitism (IBP) and quasi–parasitism (Q–P) are relatively rare. Further, it is even rarer for genetic patterns

The effect of host community functional traits on plant disease risk varies along an elevational gradient

eLife, 2021
Quantifying the relative impact of environmental conditions and host community structure on disease is one of the greatest challenges of the 21st century, as both climate and biodiversity are changing at unprecedented rates.

RNAi in the Rhizarian Phytopathogen Plasmodiophora brassicae: The Causal Agent of Clubroot Disease in Cruciferous Crops

Advanced Science, EarlyView.
This study uncovers an unusual RNAi pathway in the rhizarian pathogen Plasmodiophora brassicae. In the absence of Dicer, a Drosha‐like RNase III protein supports the biogenesis of predominant 21‐nt small RNAs, and two Argonaute proteins mediate small RNA‐guided silencing.

Common Mechanisms of Developmental Reprogramming in Plants—Lessons From Regeneration, Symbiosis, and Parasitism

Frontiers in Plant Science, 2020
Most plants are exquisitely sensitive to their environment and adapt by reprogramming post-embryonic development. The systematic understanding of molecular mechanisms regulating developmental reprogramming has been underexplored because abiotic and ...

Larval parasitism of the autumnal moth reduces feeding intensity on the mountain birch [PDF]

, 2013
Plants respond to grazing by herbivorous insects by emitting a range of volatile organic compounds, which attract parasitoids to their insect hosts. However, a positive outcome for the host plant is a necessary precondition for making the attraction ...

Escape from parasitism by the invasive alien ladybird, Harmonia axyridis [PDF]

, 2014
1. Alien species are often reported to perform better than functionally similar species native to the invaded range, resulting in high population densities, and a tendency to become invasive.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Adaptation of Echinococcus Multilocularis to Oxidative Stress Depends on EmPDK‐Mediated Metabolic Reprogramming

Advanced Science, EarlyView.
Metabolic adaption presents a vital survival strategy for E. multilocularis. This study identifies EmPDK as a central metabolic regulator governing glucose metabolic reprogramming. Oxidative stress activates EmHIF1α to induce EmPDK expression. Mechanistic characterization reveals this ROS/EmHIF1α/EmPDK axis drives glycolytic reprogramming to sustain ...
