This study identifies haplotype-specific expression of a terpene synthase gene as the source of linalool variation in Riesling grapevines, showing regulatory variation within terpene synthase clusters drives monoterpene diversity.

The paper investigates how drought and esca disease affect grapevine wood interactions with fungi, finding shared stress responses and distinct fungal adaptations under each condition.

The paper analyzes haplotype diversity at the PdR1 locus in Vitis species to identify resistance mechanisms against Pierce's Disease.

The paper identifies NLR genes associated with powdery mildew resistance loci Ren6 and Ren7 in Vitis piasezkii by analyzing phased genomes and structural variation across multiple accessions.

This study identifies genetic loci in grapevine that influence berry-associated microbial communities, including pathogenic fungi and fermentative yeasts, revealing broad genetic control over microbiome assembly.

This study traces the evolutionary history of the grape sex-determining region across angiosperms, finding it conserved in flowering plants but not in non-flowering plants.

This study uses dual-organism single-nucleus transcriptomics to analyze grapevine and Erysiphe necator gene expression during early powdery mildew infection, identifying cell type markers and immune response patterns.

This study constructs a super-pangenome of North American wild grape species to capture genetic diversity and identify loci associated with adaptive traits like salt tolerance.

The paper compares transcriptional responses of eight grape resistance loci to powdery mildew, finding distinct gene expression patterns and limited overlap between loci.

The paper reports chromosome-scale diploid assemblies of three grape rootstocks using PacBio HiFi sequences and HaploSync, providing resources for studying stress adaptation and marker development.

The paper identifies and characterizes haplotype-resolved resistance loci in Muscadinia rotundifolia, revealing structural variations affecting NLR genes involved in powdery mildew resistance.

HaploSync improves diploid genome assemblies by phasing, correcting scaffolding errors, and filling gaps in multiple species.

This study identifies GST4 as a candidate gene for berry color in muscadine grapes, showing a proline to leucine mutation correlates with black vs. bronze berry color.

The paper assembles the diploid genome of Muscadinia rotundifolia, identifies chromosome fusions, and detects expanded disease resistance genes in comparison to Vitis species.

This study uses Iso-Seq to reconstruct the transcriptome of Cabernet Sauvignon grape berries, identifying cultivar-specific genes without relying on a reference genome.

The paper identifies structural genomic variation affecting secondary metabolism gene clusters in Phaeoacremonium minimum, highlighting the need for a pan-transcriptome reference to capture virulence factor diversity.
