The Genetic Diversity of Aquilaria microcarpa interacting with Fusarium sp

Abstract

Aquilaria microcarpa is one of the agarwood-producing plants, which is currently very limited in nature. Plant defense systems are strongly influenced by the resistance genes possessed by plants. The genetic diversity of these plants would be seen by microsatellite markers as consideration in the development of this species. This research was conducted by observing the differences in gene characteristics from plants that were inoculated with Fusarium (n=40) and not inoculated (n=40). The results showed that of the 4 specific primers tested, only two primers were well amplified, with an average of 4 alleles per locus. The Polymorphism value of Information Content (PIC) at 6PA 18 locus in plant populations inoculated was 0.534. The value of genetic differential obtained from the two observed loci is high, indicating that the genetic diversity that occurs was not only influenced by the genetic makeup of plants, but also environmental factors where the plant grows.
