The research interests of plant virology Group are covering both basic and applied problems in plant virology and plant virus diagnosis.

A main research interest is in tropical plant viruses, plant – virus – vector interactions and specifically the identification and validation of resistant genes by knockdown experiments. Along with, the focus is on Begomoviruses, Barley yellow dwarf virus (BYDV), Sugarcane mosaic virus (SCMV), and Citrus tristeza virus (CTV) diversity, multiple transgenic resistance(s) in significant cash crops and development of antibodies against them.

A curiosity is to standardize a protocol for Agrobacterium mediated wheat/sugarcane transformation and to create transgenic resistance in model plant system targeting Barley yellow dwarf virus, Sugarcane mosaic virus and Citrus tristeza virus. A great intension is the utilization of plant system for the development of vaccines against human viral diseases.

 

Focus of the laboratory:

Begomoviruses

Barley yellow dwarf virus (BYDV)

Sugarcane mosaic virus (SCMV)

Citrus tristeza virus (CTV)

Development of Transgenic resistance in significant cash crops

Development of diagnostic kit(s) against plant virus

Current Projects:

1.     Sugarcane productivity enhancement by development of transgenic virus resistance through expression of hairpinRNA (hpRNA) carrying Sugarcane mosaic virus derived sequences. (As PI).

2.     Development of transgenic resistance in Solanum tuberosum L. against abiotic stress, by the expression of DREB protein gene (As Co-PI).
