Soil‐dependent variation in strigolactone signaling distance revealed by a parasitic seed germination bioassay

Pest Management Science, EarlyView.
A parasitic seed germination bioassay reveals strong soil‐dependent variation in strigolactone signaling distance, controlled by physical and biological soil properties, which shapes signaling range and parasitic weed infection risk. Abstract BACKGROUND Strigolactones are root‐exuded plant metabolites acting as germination stimulants for several ...

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

The TaRNS4–TaPP2C10 module regulates wheat resistance to stripe rust through RNA degradation and MAPK cascades

Journal of Integrative Plant Biology, EarlyView.
In wheat, phosphorylation of the S‐like RNase TaRNS4 mediated by the kinase TaRLK5 promotes its degradation of Puccinia striiformis f. sp. tritici RNA in the apoplast, enhancing resistance to stripe rust. TaRNS4 can hijack phosphatase TaPP2C10 to relieve its dephosphorylation of TaMAPK6, thereby activating MAPK‐mediated immune responses. ABSTRACT RNase

Abscisic acid and the antioxidant system are involved in germination of Butia capitata seeds

Acta Botânica Brasílica, 2018
Seed germination is an important step for plants without vegetative propagation and is a physiological process that begins with specific environmental cues resulting in biochemical responses. Breaking-dormancy is necessary to study germination in dormant

Efficiency of RNAi‐based gene silencing in fungi: a meta‐analysis

New Phytologist, EarlyView.
Mechanistic interpretation of RNAi efficiency across fungal lifestyles and delivery strategies based on the present meta‐analysis. Summary RNA interference (RNAi) shows great potential to protect crops against fungal diseases, yet reported protection efficiencies vary greatly, and our understanding of the factors responsible for this variance remains ...

Broomrape weeds. Underground mechanisms of parasitism and associated strategies for their control: a review.

Frontiers in Plant Science, 2016
Broomrapes are plant-parasitic weeds which constitute one of the most difficult-to-control of all biotic constraints that affect crops in Mediterranean, central and eastern Europe, and Asia.

Subversion of plant endomembrane trafficking by a Plasmodiophora brassicae effector PbALE that recruits membrane components at the host–pathogen interface to aid in colonization

New Phytologist, EarlyView.
Schematics of ΔSPPbALE‐induced disruption of plant endomembrane trafficking impairs both preinvasive and postinvasive immunity against filamentous fungi and facilitates intracellular colonization by Plasmodiophora brassicae. Summary Plasmodiophora brassicae, an intracellular biotrophic protist that causes clubroot in crucifers, extensively alters the ...

Modulation of Anaphase‐Promoting Complex Genes Regulates Root‐Knot Nematode Gall Development and Plant Susceptibility

Plant, Cell &Environment, EarlyView.
ABSTRACT The anaphase‐promoting complex/cyclosome (APC/C) is a multi‐subunit E3 ubiquitin ligase that regulates cell cycle progression, but its role in plant‐pathogen interactions is poorly understood. Here, we demonstrate that regulation of the ubiquitin–proteasome system, involving APC/C‐associated components, is critical for coordinating host cell ...

CRISPR gene editing to improve crop resistance to parasitic plants

Frontiers in Genome Editing, 2023
Parasitic plants pose a significant threat to global agriculture, causing substantial crop losses and hampering food security. In recent years, CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) gene-editing technology has emerged as a ...
