Resistance to Elsinoë ampelina and expression of related resistant genes in Vitis rotundifolia Michx. grapes.

Muscadine grapes (Vitis rotundifolia Michx) are considered as excellent genetic resources for grape breeding programs as they are known for their hardiness and resistance to pests and diseases. However, contrary to popular belief, our study indicated that not all muscadine cultivars are resistant to anthracnose disease. In order to identify a source of genetic tolerance towards anthracnose among muscadine cultivars, a series of in-situ and ex-situ experiments were conducted through strict and sensitive screening processes.

Proteomics approach to identify unique xylem sap proteins in Pierce's disease-tolerant Vitis species.

Pierce's disease (PD) is a destructive bacterial disease of grapes caused by Xylella fastidiosa which is xylem-confined. The tolerance level to this disease varies among Vitis species. Our research was aimed at identifying unique xylem sap proteins present in PD-tolerant Vitis species.

Characterization of unique and differentially expressed proteins in anthracnose-tolerant Florida hybrid bunch grapes.

Anthracnose is a major disease in Florida hybrid bunch grapes, caused by a fungus viz. Elsinoe ampelina. Florida hybrid bunch grapes are grown in southeastern USA for their superior wine characteristics.

Cloning and characterization of differentially expressed genes of internal breakdown in mango fruit (Mangifera indica).

Internal breakdown in mango fruits has become a major concern in recent years. This disorder renders the fruits unfit for human consumption. The overall loss due to this disorder is about 35-55%.
