Abstract:

ISSR (Inter-Simple Sequence Repeat) markers are molecular markers used in genetics to analyze genetic diversity by amplifying regions of DNA located between microsatellites. They are generated using polymerase chain reaction (PCR) with a single primer, which is a short, repeating sequence (like a microsatellite). The resulting fragments provide a genetic fingerprint that is highly polymorphic, cost-effective, and useful for applications like genetic mapping, cultivar identification, and studying genetic relationships. ISSR markers show a high level of variation among individuals and are particularly good at detecting genetic diversity in plants.
