RESEARCH INTERESTS
I Molecular interactions between grapevine and obligate biotrophic
Uncinula necator
Powdery mildew caused by the fungus Uncinula necator is the
most destructive fungal disease in grapevines worldwide. U. necator
thrives only on living grapevine tissues by getting nutrients through an
elaborate feeding
structure called haustoria formed between fungus and
epidermal cell. Research in my laboratory focuses on understanding molecular
mechanisms underlying this intimate relationship between grapevine and U.
necator. We conduct the following projects, hopefully, to reveal key
steps in the complex interactions that happen after fungal conidiospores
start to germinate on the surfaces of leaf, stem, and berry in a grapevine.
These projects are part of the overall long-term objectives in the Center
for Grapevine Biotechnology.
I.a. Histological study of grapevine and U. necator
interaction
I.b. Identify powdery mildew-responsive genes in grapevines
I.c. Isolation of powdery mildew-responsive regulatory elements in
grapevines
I.d. Arabidopsis thaliana as a model plant for functional analysis
of grapevine genes
II Characterization of graft-transmissible diseases in grapevine
A severe disease infecting Chardonnay vines has emerged in a commercial
vineyard. We have investigated the possible causal pathogens
through bio-indexing, ELISA and RT-PCR. The results suggest that the agents
causing the disease are graft-transmissible and appear to be virus or
virus-like pathogens based on the induced symptoms on original vines and
three grapevine indicator plants. We are applying dsRNA
procedures, PCR, and other molecular tools to unveil the identity of
graft-transmissible causal pathogens.
III Grapevine Importation and Certification Program.
A USDA permit allows us to introduce grape cultivars from other
countries. Our team provides
quarantine services for testing grapevines viruses in the introduced grape
cultivars, investigates emerging grapevine viruses, and produces clean
grapevine stocks. The Program is funded jointly by the Missouri Wine and
Grape Board, and the Viticulture Consortium-East Section
