Abstract
Towards a Unified View on Taxonomy of P. solanacearum (Smith 1896) Smith 1914.
M. Machmud. P. solanacearum, the bacterial wilt pathogen, is a complex and heterogeneous species. Studies have proven that the bacterium is composed of a number of different strains differing in host range, colony morphology, physiology and biochemistry, fatty acid and membrane proteins profiles, phage susceptibility, serological reactions. Because of complexity of the species, control of the disease has not been very successful. Two popular schemes are currently used in grouping of the bacterial isolates, i.e. race and biovar groupings. Each of the schemes is an attempt to establish meaningful categories on the basis of phenotypic characters. However, there seems to
be no correlation between the race and the biovar groupings, this is because the race system is based on ecological categories (host ranges), while the biovar grouping is based on phenotypic characters. Bacterial wilt scientists have put many efforts to study various aspects related to taxonomy of the pathogen. In the past decade, with the advancement of DNA technology, scientists have used molecular genetic techniques such as whole genome analysis, finger printing techniques and PCR to study systematic and phytogeny of the bacterium. This paper is a brief review on various works on molecular techniques that have been done by scientists to unify view on taxonomy
of P. solanacearum.
