Pathogen diversity and diagnosisDetailed knowledge of pathogen diversity is a prerequisite to developing unambiguous diagnostic tools. Pathogen populations are characterized by DNA molecular markers (SSRs, ISSRs, sequencing specific genes) and the data generated is used to interpret origin, spread, taxonomy and phylogeny.
Our research also focuses on the development of novel molecular techniques for detection and diagnosis. Methods include DNA -based and other nucleic acid-based alternatives to the polymerase chain reaction (e.g LAMP). Our focus is to develop methods which are simple, rapid, cost effective and eliminate the delay in implementation of disease management tactics associated with traditional morphological methods.
Presently, our current research is on pathogens of economic importance in tobacco production e.g Root knot nematode, PVY, TMV, Pythium, Pseudomonas and Granville wilt.
