Cross-Kingdom RNAi of Pathogen Effectors Leads to Quantitative Adult Plant Resistance in Wheat [PDF]

Frontiers in Plant Science, 2020
Cross-kingdom RNA interference (RNAi) is a biological process allowing plants to transfer small regulatory RNAs to invading pathogens to trigger the silencing of target virulence genes. Transient assays in cereal powdery mildews suggest that silencing of

sRNA Profiling Combined With Gene Function Analysis Reveals a Lack of Evidence for Cross-Kingdom RNAi in the Wheat – Zymoseptoria tritici Pathosystem [PDF]

Frontiers in Plant Science, 2019
Cross-kingdom small RNA (sRNA) silencing has recently emerged as a mechanism facilitating fungal colonization and disease development. Here we characterized RNAi pathways in Zymoseptoria tritici, a major fungal pathogen of wheat, and assessed their ...

Botrytis small RNA Bc-siR37 suppresses plant defense genes by cross-kingdom RNAi. [PDF]

RNA Biol, 2017
Pathogens secrete effector proteins to suppress host immune responses. Recently, we showed that an aggressive plant fungal pathogen Botrytis cinerea can also deliver small RNA effectors into host cells to suppress host immunity. B. cinerea sRNAs (Bc-sRNAs) translocate into host plants and hijack the plant RNAi machinery to induce cross-kingdom RNAi of ...

A rice ceRNA module suppresses Rhizoctonia solani–induced cross-kingdom RNAi to reduce fungal pathogenicity [PDF]

Nature Communications
Cross-kingdom RNA interference (RNAi) is a key virulence mechanism in which pathogens deliver small RNAs (sRNAs) into host plants, hijacking host ARGONAUTE (AGO) proteins to silence immunity-related genes.

Cross-Kingdom Small RNAs among Animals, Plants and Microbes

Cells, 2019
Small RNAs (sRNAs), a class of regulatory non-coding RNAs around 20~30-nt long, including small interfering RNAs (siRNAs) and microRNAs (miRNAs), are critical regulators of gene expression.

Cross-kingdom RNAi: a universal mechanism of inter-organismal communication with many unknowns. [PDF]

J Exp Bot
Abstract Cross-kingdom RNAi (ck-RNAi) is a biological process in which small RNA (sRNA) molecules are transferred between organisms belonging to different kingdoms to silence specific genes. Although numerous instances of reciprocal ck-RNAi have been documented in plants, demonstrating a modulation of the interaction between plants ...

Fungal small RNA: unveiling the breakthroughs and promising applications [PDF]

Frontiers in Fungal Biology
Small RNAs (sRNAs) are abundant endogenous non-coding RNAs in eukaryotic organisms that regulate gene expression by binding to their target mRNAs either completely or partially.

Spray-induced gene silencing for plant disease control: mechanistic basis and deployment-oriented design [PDF]

Frontiers in Plant Science
Spray-induced gene silencing (SIGS) is a transgene-free, biodegradable RNA-based approach for crop protection in which exogenously applied double-stranded RNA (dsRNA) is taken up and processed by plants or susceptible pathogens to drive the sequence ...

RNA Interference in Plant Interactions with Pathogenic Microorganisms: A Weapon or a Liability? [PDF]

Current Issues in Molecular Biology
The RNA interference machinery is crucial for regulating the activity of both native and foreign genes across all eukaryotes. The core protein families involved in this process are Dicer-like, Argonaute, and RNA-dependent RNA polymerase.

Tracking of Tobacco Mosaic Virus in Taxonomically Different Plant Fungi [PDF]

Journal of Fungi
Plant viruses have been traditionally considered pathogens restricted to plant hosts. However, recent studies have shown that some plant viruses can infect and replicate in filamentous fungi and oomycetes, suggesting that their host range is broader than
