Analysis reveals genetic diversity and phylogeny of grapevine cultivars, indicating historical dispersal patterns.

This research aims to investigate the genetic diversity and phylogenetic relationships of grapevine cultivars using chloroplast SNVs.
Analyzed chloroplast SNV markers in 409 V. vinifera accessions via whole-genome shotgun sequencing.
Detected 93 SNVs across 24 chloroplast genes, focusing on the most variable genes.
Conducted haplotype analysis to identify 102 distinct haplotypes with geographic structuring.
Validated findings by comparing selected SNV markers with target capture sequencing.
Identified 102 distinct haplotypes with clear patterns: ATT in Eastern Mediterranean, ATA in Western Europe.
Observed high variability in the ycf1 gene, significant for species differentiation.
Demonstrated the accuracy of shotgun sequencing with minimal discrepancies for variant detection.
Delineated three major haplotype clusters reflecting historical human-mediated dispersal of grapevine cultivars.
