Microsatelites in general are sensitive markers used for low-level identification because their high variability. I think that you have to more precise identification of rare plants in such way. Microsatellites is very helpful in such cases as analysis and distinguishing on specific or infraspecific levels of plants with hard taxonomy. Also such markers widely used for studies in population genetics and can potentially show the processes inside genome of plants in populations. But it also depend on what plants you planned to analyse for such way and what the main goal of your research.
Microsatellites are codominant markers, thus allow to retrieve the exact genotype of each individual for the locus analyzed. The ability to distinguish the alleles present in a population (or related populations) is very useful for the study of processes such as genetic drift, population bottlenecks, founder effects, inbreeding, etc., which are essential for risk assessment analyses in conservation biology. For plant species, these markers are useful to study their reproductive biology (whether they are self- or cross-pollinated), which is also useful knowledge for their conservation.
Microsatellites is very useful to parentage, maping and genetic diversity and conservation field for the molecullar marker stable,co-dominate and low exploring cost.Of course, the twins from the one egg is a excepion.
Microsatellites are tandemly repeated regions in the nuclear genome, which can use for intratranspacific identifications of different populations. The data will be useful for population genetic studies to determine population bottleneck and expansion. It will helpful to identify isolated populations which are going to threaten or extinct in near future, which need urgent conversational treat.
