An atypical NLR gene confers bacterial wilt susceptibility in Arabidopsis.

Quantitative disease resistance (QDR) remains the most prevalent form of plant resistance in crop fields and wild habitats. Genome-wide association studies (GWAS) have proved to be successful in deciphering the quantitative genetic basis of complex traits such as QDR. To unravel the genetics of QDR to the devastating worldwide bacterial pathogen Ralstonia solanacearum, we performed a GWAS by challenging a highly polymorphic local mapping population of Arabidopsis thaliana with four R.

DNA demethylation and hypermethylation are both required for late nodule development in Medicago.

Plant epigenetic regulations are involved in transposable element silencing, developmental processes and responses to the environment. They often involve modifications of DNA methylation, particularly through the DEMETER (DME) demethylase family and RNA-dependent DNA methylation (RdDM). Root nodules host rhizobia that can fix atmospheric nitrogen for the plant's benefit in nitrogen-poor soils.

APOK3, a pollen killer antidote in Arabidopsis thaliana.

The principles of heredity state that the two alleles carried by a heterozygote are equally transmitted to the progeny. However, genomic regions that escape this rule have been reported in many organisms. It is notably the case of genetic loci referred to as gamete killers, where one allele enhances its transmission by causing the death of the gametes that do not carry it.
