AbstrakStrategi klasik yang meliputi perbandingan anatomi, fisiologi dan sitogenetika telah banyak diterapkan untuk mengidentifikasi karakter tertentu serta untuk menentukan keragaman dan hubungan antar dan intra spesies. Namun, saat ini penanda molekuler telah melengkapi strategi sebelumnya dengan sangat cepat. Berbagai jenis penanda molekuler digunakan untuk menilai tingkat polimorfisme DNA. Penanda molekuler ini diklasifikasikan sebagai penanda berbasis hibridisasi dan berbasis Polymerase Chain Reaction (PCR). Dalam beberapa tahun terakhir, sistem penanda DNA yang berbeda seperti Restriction Fragment Length Polymorphisms (RFLPs), Random Amplied Polymorphic DNAs (RAPDs), Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs) yang juga disebut Mikrosatelit, Single Nucleotide Polymorphims (SNPs) dan lain-lain telah dikembangkan dan diterapkan pada berbagai spesies tanaman. Penanda molekuler ini dapat digunakan untuk sidik jari DNA dan studi keragaman genetik. Sidik jari berdasarkan DNA telah banyak digunakan dalam ilmu forensik, juga memiliki berbagai aplikasi dalam pemuliaan tanaman. Tulisan ini memberikan overview tentang berbagai penanda molekuler dan aplikasinya untuk sidik jari dan kajian keragaman genetik tanaman berdasarkan DNA pada berbagai spesies tanaman, dan secara khusus pada Coffea sp.AbstractConventional strategies including comparative anatomy, physiology and cytogenetics were applied to identify the certain character as well as to determine inter- and intra-species diversity and relationships. However, more recently molecular markers have very rapidly complemented the previous strategies. Various types of molecular markers are used to assess DNA polymorphism. They are classified as hybridization-based markers and polymerase chain reaction (PCR) based markers. In recent years, different DNA marker systems such as Restriction Fragment Length Polymorphisms (RFLPs), Random Amplied Polymorphic DNAs (RAPDs), Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs) which also called as microsatellites, Single Nucleotide  Polymorphims  (SNPs)  and  others  have been developed and applied to a range of plant species. These molecular markers can be used for DNA fingerprinting and genetic diversity study. DNA fingerprinting has been widely used in forensic science, but is has also a variety of application in plant breeding. This paper provides an overview about various molecular markers and their application for DNA plant fingerprinting and genetic diversity, especially in Coffea sp.

A reliable data set is a fundamental prerequisite for consistent results and conclusions in population genetic studies. However, marker scoring of genetic fingerprints such as amplified fragment length polymorphisms (AFLPs) is a highly subjective procedure, inducing inconsistencies owing to personal or laboratory-specific criteria. We applied two alternative marker selection algorithms, the newly developed script scanAFLP and the recently published AFLPScore, to a large AFLP genome scan to test how population genetic parameters and error rates were affected. These results were confronted with replicated random selections of marker subsets. We show that the newly developed marker selection criteria reduced the mismatch error rate and had a notable influence on estimates of genetic diversity and differentiation. Both effects are likely to influence biological inference. For example, genetic diversity (HS) was 29% lower while genetic differentiation (FST) was 8% higher when applying scanAFLP compared with AFLPScore. Likewise, random selections of markers resulted in substantial deviations of population genetic parameters compared with the data sets including specific selection criteria. These randomly selected marker sets showed surprisingly low variance among replicates. We conclude that stringent marker selection and phenotype calling reduces noise in the data set while retaining patterns of population genetic structure.

The levels of genotypic and genetic variation were estimated in six natural populations of arctic bramble (Rubus arcticus L. subsp. arcticus) in Finland. Using three primer combinations, a total of 117 amplified fragment length polymorphisms (AFLP) were found. The results were highly reproducible and allowed identification of 78 genets among the 122 plants of arctic bramble studied. Genotypic variation measured as Simpson index (D) was high in all populations, ranging from 0.72 to 0.94. Also, the level of genetic variation measured as Shannon index was relatively high in all populations, ranging from 0.19 to 0.32 (average 0.26). The high levels of genetic diversity indicate that sexual reproduction has played a significant role in these populations. The hierarchical analysis of molecular variance (AMOVA) partitioned 48% of the genetic variation among populations, suggesting a high level of population differentiation and a low level of interpopulation gene flow. Genetic diversity among ten currently grown cultivars of arctic bramble and hybrid arctic bramble (R. arcticus subsp. arcticus × R. arcticus subsp. stellatus) was large, and the subspecies were clearly distinguished from each other based on the AFLP marker data.Key words: AFLP, AMOVA, population, natural habitat, Rubus arcticus subsp. arcticus, Rubus arcticus subsp. stellatus.
