AI Article Synopsis
- Grapevine fanleaf disease, caused by the grapevine fanleaf virus (GFLV) and transmitted by the nematode Xiphinema index, leads to serious economic losses for vineyards globally.
- Researchers have found that the Riesling grape variety shows resistance to GFLV, linked to a single recessive factor called rgflv1 on chromosome 1.
- This discovery could lead to new grapevine rootstocks that are resistant to GFLV, offering an environmentally friendly solution that wasn't previously available, and rgflv1 appears to be different from other virus susceptibility factors in plants.
Article Abstract
Grapevine fanleaf disease, caused by grapevine fanleaf virus (GFLV), transmitted by the soil-borne nematode Xiphinema index, provokes severe symptoms and economic losses, threatening vineyards worldwide. As no effective solution exists so far to control grapevine fanleaf disease in an environmentally friendly way, we investigated the presence of resistance to GFLV in grapevine genetic resources. We discovered that the Riesling variety displays resistance to GFLV, although it is susceptible to X. index. This resistance is determined by a single recessive factor located on grapevine chromosome 1, which we have named rgflv1. The discovery of rgflv1 paves the way for the first effective and environmentally friendly solution to control grapevine fanleaf disease through the development of new GFLV-resistant grapevine rootstocks, which was hitherto an unthinkable prospect. Moreover, rgflv1 is putatively distinct from the virus susceptibility factors already described in plants.
