Abstract: | Caesalpinia echinata, commonly known as Pau-brasil (Brazilwood), the famous tree that named Brazil is native to the Atlantic forest. Men extensively
exploited it ever since discovery and colonial times due to its value as a source of red dye. As a consequence, Brazilwood
is a threatened species with populations reduced to small forest fragments. Ten polymorphic microsatellite loci were developed
from an enriched genomic library. Using fluorescently-labeled primers, a total of 83 alleles were found after analyzing a
sample of 44 trees. These high genetic information content markers should allow detailed investigations of mating systems,
gene flow, population structure and paternity in natural populations. |
