Polymerase chain reaction detection of candidatus liberibacter asiatic associated with citrus huanglonbing

Journal Title: Scientific Journal of Animal Science - Year 2012, Vol 1, Issue 2

Abstract

Polymerase chain reaction diagnosis of Candidatus liberibacter asiatic associated with citrus Huanglonbing disease is molecular technique which is used for detection of disease when pathogen present is very low concentration in disease sample. Among these three DNA isolation methods viz., commercial kit method, sodium sulphite method and membrane bard nucleic acid technique, sodium sulphite method is cost effective for commercial use. In nucleic acid membrane method for DNA extraction isolation there is no use of liquid nitrogen. Polymerase chain reaction detection of disease is based on principal of thermal cycling in which PCR instrument allow to run generally 60-65 thermal cycle, during PCR operation it allow different stages of cycle at different temperatures for different period of time i.e. initiation (940C), denaturation (940C), primer annealing (600C), extension/elongation step (720C), final elongation (720C) and holding temperature (40C). PCR based diagnosis system is developed for detection of greening bacteria. The comparative cost of detection by various combinations of reagent and sampling time was determined and cost effective technology was standardized and validated.
