Dissection of the Ren6 and Ren7 powdery mildew resistance loci in Vitis piasezkii DVIT2027 using phased parental-progeny genomes and intraspecific locus graph reconstruction

Mélanie Massonnet, Rosa Elia Figueroa-Balderas, Noé Cochetel, Summaira Riaz, Dániel Pap, M. Andrew Walker, Dario Cantù

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.

The grape powdery mildew resistance loci Ren2, Ren3, Ren4D, Ren4U, Run1, Run1.2b, Run2.1, and Run2.2 activate different transcriptional responses to Erysiphe necator

Mélanie Massonnet, Summaira Riaz, Dániel Pap, Rosa Elia Figueroa-Balderas, M. Andrew Walker, Dario Cantù

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

The genomic diversification of clonally propagated grapevines

Amanda M. Vondras, Andrea Minio, Barbara Blanco‐Ulate, Rosa Elia Figueroa-Balderas, Michael A. Penn, Yongfeng Zhou, Danelle K. Seymour, Zirou Ye, Dingren Liang, Lucero Espinoza, Michael M. Anderson, M. Andrew Walker, Brandon S. Gaut, Dario Cantù

This study analyzes somatic mutations in clonally propagated grapevines, finding that repetitive intergenic regions drive genome diversification and that deleterious mutations accumulate in clones.
