Genetic analysis of grapevine root system architecture and loci associated gene networks.
Front Plant Sci
February 2023
Own-rooted grapevines and grapevine rootstocks are vegetatively propagated from cuttings and have an adventitious root system. Unraveling the genetic underpinnings of the adventitious root system architecture (RSA) is important for improving own-rooted and grafted grapevine sustainability for a changing climate. Grapevine RSA genetic analysis was conducted in an 'VRS-F2' population.

- Increased map density and the ability to transfer genetic markers are important for studying fruit quality and stress tolerance in grapevines.
- Researchers developed a detailed genetic map for an interspecific grapevine population using various markers, resulting in a map with over 2500 markers that aligns well with the 'PN40024' grape genome.
- They identified key quantitative trait loci (QTL) related to berry skin color, flower type, and malic acid content, including a novel QTL for a specific grape aroma compound, which provides insights into breeding for desired traits.
, a critically important Native American grapevine species, is used globally in rootstock and scion breeding and contributed to the recovery of the French wine industry during the mid-19th century phylloxera epidemic. This species has abiotic and biotic stress tolerance and the largest natural geographic distribution of the North American grapevine species. Here we report an Illumina short-read 369X coverage, draft de novo heterozygous genome sequence of Michx.
