Summary
Discovering new crop protection strategies beyond resistance genes (R genes) is crucial. Exploring susceptibility genes (S genes) and using omics tools offers promising, broad-spectrum resistance while maintaining plant health.
Area of Science:
- Plant pathology
- Genetics
- Agricultural science
Background:
- Traditional resistance gene (R gene)-based crop protection is limited by rapid pathogen evolution.
- Pathogens exploit plant susceptibility genes (S genes) during infection, presenting an alternative control target.
Purpose of the Study:
- To review integrated multi-omics approaches for identifying novel crop resistance strategies.
- To explore mechanisms of R-gene breakdown and omics-driven methods for sustainable crop protection.
Main Methods:
- Literature review focusing on R-gene limitations and S-gene manipulation.
- Analysis of integrated multi-omics tools for identifying resistance mechanisms.
- Discussion of omics-driven strategies for long-term crop protection.
Main Results:
- S-gene manipulation shows potential for broad-spectrum crop resistance.
- Understanding R-gene breakdown is key to developing durable resistance.
- Multi-omics approaches offer new avenues for crop protection.
Conclusions:
- Shifting focus to S genes and employing omics technologies can enhance crop resilience.
- Balancing S-gene strategies with plant fitness is essential for field application.
- Integrated omics tools are vital for developing next-generation, sustainable crop protection.

19.1K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

11.6K
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

24.8K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

28.8K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
