Genetic Diversity and Fine-scale Genetic Structure in Syagrus oleracea (Mart.) Becc.: A Survivor Palm Species of the Semiarid | Chapter 09 | Research and Development in Agricultural Sciences Vol. 1
The species Syagrus oleracea is a native palm tree, present in highly impacted environments of the Brazilian semiarid. This species is exploited for use in the manufacture of folk crafts and for human and animal feeding. The objective of this study was to characterize the diversity and genetic structure of individuals from different populations, located in anthropic regions of the Brazilian semiarid region, in the state of Minas Gerais. This information is important for species management and conservation strategies. Thus, we used ISSR molecular markers in 157 individuals in seven populations of S. oleracea. Looking at the results, one can observe that amplifications of 109 locos occurred and that an average of 18, 17 alleles were found on each primer, values that demonstrated that the ISSR technique used was highly efficient. The genetic diversity indexes were observed, showing expected heterozygosity (He) and Shannon index (I) of 0.260 and 0.383, respectively. The number of allele...
