Haplotype graph analysis of <i>PdR1</i> uncovers resistance diversity to Pierce’s Disease in <i>Vitis arizonica</i> and its hybrids

2025-12-26

Abstract excerpt

Previous genetic mapping studies indicate that multiple haplotypes of the Pierce’s disease (PD) Resistance 1 (PdR1) locus occur in Vitis arizonica and its hybrids. To characterize sequence diversity at this locus, we assembled chromosome-scale diploid genomes for four PD-resistant (PD-R) accessions: b43-17 ( PdR1a⁺/PdR1b⁺ ), the backcross 07744-094 ( PdR1c⁺/PdR1⁻ ), b46-43 ( PdR1e⁺/PdR1f⁺ ), and b42-26 ( PdR...
