HiFi chromosome-scale diploid assemblies of the grape rootstocks 110R, Kober 5BB, and 101-14 Mgt
The three North American Vitis species, V. riparia, V. rupestris, and V. berlandieri, are the main species used for breeding grape rootstocks. Here, we report the diploid chromosome-scale assembly of three widely used rootstocks derived from these species: Richter 110 (110R), Kober 5BB, and 101-14 Millardet et de Grasset (Mgt).[... see more]

Assembly of complete diploid phased chromosomes from draft genome sequences
HaploSync uses a genetic map and/or the genome of a closely related species to guide the scaffolding of a diploid assembly into phased pseudomolecules for each chromosome. It compares alternative haplotypes to identify and correct misassemblies independent of a reference, fills assembly gaps with unplaced sequences, and resolves collapsed homozygous regions.[... see more]

Haplotype-resolved powdery mildew resistance loci reveal the impact of heterozygous structural variation on NLR genes in Muscadinia rotundifolia
Muscadinia rotundifolia cv. Trayshed is a valuable source of resistance to grape powdery mildew. It carries two powdery mildew resistance-associated genetic loci, Run1.2 on chromosome 12 and Run2.2 on chromosome 18. The purpose of this study was to identify candidate resistance genes associated with each haplotype of the two loci.[... see more]

03.07.2022 - New Paper
‘Nebbiolo’ genome assembly allows surveying the occurrence and functional implications of genomic structural variations in grapevines (Vitis vinifera L.).
We employed a multiple platform approach to produce long-range genomic data for two different ‘Nebbiolo’ clones, namely: optical mapping, long-reads and linked-reads. We performed a haplotype-resolved de novo assembly for cultivar ‘Nebbiolo’ (clone CVT 71) and used an ab-initio strategy to annotate it.. [... see more]

Characterization of the grape powdery mildew genetic resistance loci in Muscadinia rotundifolia Trayshed
Muscadinia rotundifolia cv. Trayshed is a valuable source of resistance to grape powdery mildew (PM). It carries two PM resistance (R) loci, Run1.2 on chromosome 12 and Run2.2 on chromosome 18. This study identified the nucleotide-binding leucine-rich repeat (NLR) genes composing each R locus and their associated defense mechanisms.[... see more]

Rootstock influences the effect of grapevine leafroll-associated viruses on berry development and metabolism via abscisic acid signalling
Using a dedicated experimental vineyard, we studied the responses to Grapevine leafroll-associated virus (GLRaV) in ripening berries from Cabernet Franc grapevines grafted to different rootstocks and with zero, one, or pairs of leafroll infection(s). [... see more]

Multiple independent recombinations led to hermaphroditism in grapevine
We studied the grape sex-determining region (SDR) in 12 Vitis genomes and demonstrated its conservation across 556 genotypes including 193 accessions from 47 world-wide wild grapevine species and 363 accessions of cultivated grapevine. Although the grape SDR is recombination free in all wild species, we found two distinct hermaphrodite (H) haplotypes [... see more]

Diploid chromosome-scale assembly of the Muscadinia rotundifolia genome supports chromosome fusion and disease resistance gene expansion during Vitis and Muscadinia divergence
Muscadinia rotundifolia, has been cultivated for centuries in the southeastern United States and is resistant to pathogens that detrimentally affect Vitis vinifera. Single molecule real-time reads were combined with optical maps to reconstruct the two haplotypes of each of the 20 M. rotundifolia chromosomes [... see more]
