Mutation bias shapes gene evolution in Arabidopsis thaliana

The paper shows that mutation rates in Arabidopsis thaliana are influenced by cytogenetic features and are lower in genes with deleterious mutations, contradicting neutral expectations.

Host-associated microbe PCR (hamPCR): accessing new biology through convenient measurement of both microbial load and community composition

The paper introduces hamPCR, a method to measure microbial load and community composition from amplicon sequencing, demonstrating its accuracy and scalability across different host-microbe systems.

A singleton NLR of recent origin causes hybrid necrosis in Arabidopsis thaliana

The paper identifies a singleton NLR gene, DM10, and its interaction with DM11 causing hybrid necrosis in Arabidopsis thaliana.

The relationship between microbial population size and disease in the Arabidopsis thaliana phyllosphere

The paper assesses microbial load and composition in Arabidopsis thaliana phyllosphere using shotgun metagenomics, finding high microbial loads correlate with pathogen proliferation and reduced diversity.

A new role for histone demethylases in the maintenance of plant genome integrity

This study identifies ELF6 and REF6 as JMJ histone demethylases in Arabidopsis that maintain H3K27me3 and H3K27me1 homeostasis, preventing epigenetic imprints and transposon activation during sexual reproduction.

Finding genetic variants in plants without complete genomes

The paper reanalyzes GWAS data using k-mers derived from raw sequencing to detect structural variants and missing regions in plant genomes, finding stronger associations than SNPs.

Importance of parental genome balance in the generation of novel yet heritable epigenetic and transcriptional states during doubled haploid breeding

The paper identifies imbalanced parental genome contributions as a source of transcriptional and epigenetic variation in doubled haploid plants, revealing a role for epigenetic modification of transposons in generating heritable phenotypic diversity.

Specific Regulation of TCP genes by miR319

The paper confirms that TCP genes are not targeted by miR159 and shows that specific sequence differences enable miR319 to regulate TCP transcription factors.

Multiple modes of convergent adaptation in the spread of glyphosate-resistant Amaranthus tuberculatus

This study investigates the genetic mechanisms of glyphosate resistance in Amaranthus tuberculatus, finding multiple modes of convergent adaptation through gene flow and de novo mutations in different populations.

Oligomerization of the NLR immune receptor RPP7 triggered by the atypical resistance protein RPW8/HR as a ligand

The paper shows that HR4Fei-0 disrupts RPP7bLerik1-3 oligomerization, triggering NLR signaling and cell death, while HR4Col-0 does not.

A map of climate change-driven natural selection in Arabidopsis thaliana

The paper assesses climate change-driven natural selection in Arabidopsis thaliana by analyzing fitness impacts of rainfall manipulation across different geographic regions.

The Arabidopsis thaliana pan-NLRome

The paper defines the Arabidopsis thaliana pan-NLRome by analyzing NLR diversity across 65 accessions, finding that 40 accessions saturate the NLRome and identifying architectural diversity and selective forces.

Long-term balancing selection drives evolution of immunity genes in Capsella

The paper shows that balancing selection maintains genetic diversity at immunity genes across Capsella species after population bottlenecks.

Modulation of ACD6 dependent hyperimmunity by natural alleles of an Arabidopsis thaliana NLR resistance gene

The paper investigates how natural alleles of the NLR gene SNC1 modulate the autoimmune activity of the ACD6 gene in Arabidopsis thaliana, revealing genetic interactions that influence immune system trade-offs.

Adaptive diversification of growth allometry in the plant Arabidopsis thaliana

The paper shows that Arabidopsis thaliana accessions exhibit variation in growth allometry linked to climate adaptation, with PUB4 gene under balancing selection affecting trade-offs between stress resistance and seed production.

Incomplete reprogramming of cell-specific epigenetic marks during asexual reproduction leads to heritable phenotypic variation in plants

Stability of association between Arabidopsis thaliana and Pseudomonas pathogens over evolutionary time scales

The paper surveys Pseudomonas in Arabidopsis thaliana over multiple years and sites, finding that pathogenic sublineages coexist without a single dominant strain overtaking populations.

The genetic architecture of recurrent segregation distortion in Arabidopsis thaliana

This study identifies segregation distortion in Arabidopsis thaliana by analyzing over 500 segregating populations using reduced-representation genome sequencing, revealing biased allele transmission in up to a quarter of populations.

Genomic basis and evolutionary potential for extreme drought adaptation in Arabidopsis thaliana

The paper predicts future genetic changes in A. thaliana populations by integrating climate change models with genomic data from experimental drought survival experiments.
