Plant Virology 

Research Interests :


  • Banana bunchy top virus (BBTV) is the most devastating virus disease of bananas. The virus is transmitted by the banana aphid (Pentalonia nigronervosa) in a persistent manner. New growth from infected plants is stunted and distorted, resulting in a characteristic "bunchy top" appearance. No fruit is produced on infected plants, and a high incidence of BBTV in production areas can cause complete yield loss. Specific objectives of this project are: (1) to develop rapid, sensitive, and reliable assays for detection of BBTV in plants and insects; (2) to characterize the genome organization and vector transmission of BBTV; and (3) to develop resistant transgenic banana plants to control BBTV.
  • Mealybug wilt of pineapple (MWP) is a devastating disease found in all the pineapple-growing regions of the world. The disease is characterized by severe leaf tip dieback, downward curling of the leaf margins, and reddening and wilting of the leaves that can lead to total collapse of the plant. Specific objectives of this project include: (1) to develop rapid detection assays for the closterovirus; (2) to study the cause (etiology) of MWP; (3) to examine the epidemiology of the virus; and (4) to develop alternative, environmentally sound strategies to manage MWP.
