Summary
Altering plant susceptibility (S) genes, which facilitate pathogen compatibility, can offer durable, broad-spectrum resistance. However, mutations in S genes require careful assessment due to potential side effects on plant health.
Area of Science:
- Plant pathology
- Genetics
- Agricultural science
Background:
- Conventional plant resistance relies on narrow-spectrum genes easily overcome by pathogens.
- Disease development stems from compatible interactions between plants and pathogens.
Purpose of the Study:
- To review susceptibility (S) genes that facilitate pathogen compatibility.
- To explore mechanisms of loss of compatibility for durable resistance breeding.
Main Methods:
- Review of existing literature on plant susceptibility genes.
- Categorization of S genes based on their role in infection stages.
Main Results:
- Identified three groups of S genes: early establishment, defense modulation, and pathogen sustenance.
- S genes offer potential for broad-spectrum and durable resistance in plants.
Conclusions:
- Altering S genes is a promising strategy for resistance breeding.
- Side effects of S gene mutations necessitate individual evaluation for practical application.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

16.7K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

01:26Factors Affecting the Risk of Infection
14.6K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

97
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
