ISSR: a reliable and cost-effective technique for detection of DNA polymorphism.

With the emergence of more and more molecular markers as useful tools in plethora of population genetic and phylogenetic studies, choice of marker system for a particular study has become mind boggling. These marker systems differ in their advantages and disadvantages, so it is imperative to keep in mind all the pros and cons of the technique while selecting one for the problem to be addressed.Here, we have shed light on the ISSR (intersimple sequence repeat) technique, as a marker of choice if one wants to go for properties such as reliability, simplicity, cost effectiveness, and speed, in addition to assessing genetic diversity between closely related individuals. We have outlined here the whole methodology of this technique with an example of Tribulus terrestris as case study.
