Surface Waxes in Grapevine as Target for Resistance Breeding

Ge, Xinshuang

Abstract (englisch):

Viticulture accounts for around 80% of fungicide use in Europe, a demand which is caused by several diseases that have been introduced in the 19th century, especially Powdery Mildew (Arnold, Schnitzler, Douard, Peter, & Gillet, 2005). Owing to the structure and the location of surface wax (Collinge, 2009; L. Kunst & Samuels, 2003), maybe it can block Powdery Mildew penetrating the surface wax and cuticle as well as the adhesion at the leaf surface (Wenping Qiu, 2015). It is important consequently to find out that if there are distinct resistance to the Powdery Mildew in the grape accessions which have wax accumulation differences. Further wax biosynthesis mechanism needs to be investigated in the grapevine collection. That can provide another strategy to create new varieties.
In this study, there were three types of wax morphologies discerned as long wing-like structure, small wax crystals and occurrence long wax wings with small wax crystals together in the wild ancestor of domesticated grapevine collections. Surface waxes formation and accumulation of the genotypes indicated genetic variation and wax contents stabilized at fully expanded leaves. ... mehr
