Inheritance of downy mildew (Plasmopara viticola) and anthracnose (Sphaceloma ampelinum) resistance in grapevines.
Downy mildew (Plasmopara viticola) and anthracnose (Sphaceloma ampelinum) are two of the major diseases of most grapevine (Vitis vinifera L.) cultivars grown in Thailand. Therefore, breeding grapevines for improved downy mildew and anthracnose resistance is crucial. Factorial crosses were made between three downy mildew and/or anthracnose resistant lines ('NY88.0517.01', 'NY65.0550.04', and 'NY...
متن کاملThe mode of interaction between Vitis and Plasmopara viticola Berk. & Curt. Ex de Bary depends on the host species.
In order to obtain insight into host responses to grapevine downy mildew (Plasmopara viticola), we compared pathogen development on a panel of Vitis species from North America, Asia and Europe. Leaf discs from different host species were inoculated in parallel, and the colonisation of the mesophyll was visualised by aniline blue staining and quantified with respect to infection incidence and my...
متن کاملLinking Jasmonic Acid to Grapevine Resistance against the Biotrophic Oomycete Plasmopara viticola
Plant resistance to biotrophic pathogens is classically believed to be mediated through salicylic acid (SA) signaling leading to hypersensitive response followed by the establishment of Systemic Acquired Resistance. Jasmonic acid (JA) signaling has extensively been associated to the defense against necrotrophic pathogens and insects inducing the accumulation of secondary metabolites and PR prot...
متن کاملVariation Within and Between Vitis spp. for Foliar Resistance to the Downy Mildew Pathogen Plasmopara viticola
Vitis vinifera grapevines are highly susceptible to downy mildew caused by the host-specific oomycete Plasmopara viticola. In humid climates like New York, where the unchecked pathogen will defoliate vines and destroy young fruit clusters, growers depend upon multiple fungicide applications for disease management. However, management of P. viticola by fungicides is tenuous, because the pathogen...
متن کاملStaining methods for the investigation of Plasmopara viticola and its infection structures in semi-thin sections
The investigation of Plasmopara viticola, that spends most of its life cycle inside of leaves, requires specific staining techniques. It is desirable to visualize both, host cells and parasitic structures, given their silimar chemical constitutions, especially in reference to the cell wall. On the basis of appropriate staining procedures it was possible to demonstrate parasitic structures durin...
