“…We found a higher mean number of bands per primer than that found by Angrizani et al (2013) using 11 SSR primers in 68 rosewood accessions from two localities in the central Amazon in Brazil. We also obtained higher mean polymorphism than that reported by Santos et al (2008a) for one locality in the central Brazilian Amazon using RAPD in 94 rosewood accessions.

“…Endangered species usually have low genetic diversity, mainly due to genetic drift and inbreeding in small remnant populations (Spielman et al 2004). Our results indicate a higher genetic diversity in rosewood in the Peruvian Amazon than the reported values for rosewood in the central Brazilian Amazon (Santos et al 2008a;Angrizani et al 2013). Santos et al (2008b) studied the genetic variability of four rosewood populations in central Amazonia using RAPD markers, and found higher genetic variations in Ducke Reserve, the only population under long-term protection.…”

“…Most studies on the species have been about the activity of its essential oil (Sarrazin et al 2016;Amusant et al 2016;Maia and Mourão 2016). Information about the genetic characterization of rosewood using molecular markers and its conservation management is available for populations in Brazil (Santos et al 2004, Santos et al 2008aAngrizani et al 2013), but is lacking for rosewood in Peru. There is no ex situ germplasm bank for this species in Peru, and the information available in Peruvian Amazonian herbaria on this species is limited.…”

Rosewood, Aniba rosaeodora is an endangered species in Amazon forests and its natural stands have been heavily depleted due to over-exploitation for the cosmetic industry. This study aimed to investigate the genetic diversity and population structure of 90 rosewood accessions from eight localities in the Peruvian Amazon through 11 Inter Simple Sequence Repeats (ISSR) primers. The ISSR primers produced a sum of 378 bands, of which 375 (99.2%) were polymorphic, with an average polymorphism information content (PIC) value of 0.774. The mean effective number of alleles (Ne), Shannon informative index (I), gene diversity (He) and total gene diversity (Ht) were 1.485, 0.294, 0.453 and 0.252, respectively. Analysis of molecular variance (AMOVA) showed the presence of maximum variability within populations (88%). The Structure algorithm, neighbor joining and principal coordinate analysis (PCoA) grouped the 90 rosewood accessions into three main populations (A, B and C). Diversity indices at the inter-population level revealed a greater genetic diversity in population A, due to higher gene flow. The neighbor-joining analysis grouped populations A and B, while population C was found to be divergent at the inter population level. We concluded that population A reflects higher genetic diversity and should be prioritized for future management and conservation plans.

“…SSRs in coding regions are prone to mutation and cause frame-shifts to occur, which renders the gene non-functional ( Wang, Barkley & Jenkins, 2009 ). Chloroplast SSRs have been used to evaluate genetic variations among plant genotypes ( Vendramin et al, 1999 ) and to investigate the genetic diversity of Lauraceae species ( Santos, Spironello & Sampaio, 2008 ; Zhai et al, 2010 ). The SSRs in this analysis are good resource for developing molecular markers and will be applied to molecular marker-assisted breeding, population genetics and genetic linkage map construction ( Deguilloux, Pemonge & Petit, 2004 ; Huang et al, 2014 ).…”

Cinnamomum camphora, a member of the Lauraceae family, is a valuable aromatic and timber tree that is indigenous to the south of China and Japan. All parts of Cinnamomum camphora have secretory cells containing different volatile chemical compounds that are utilized as herbal medicines and essential oils. Here, we reported the complete sequencing of the chloroplast genome of Cinnamomum camphora using illumina technology. The chloroplast genome of Cinnamomum camphora is 152,570 bp in length and characterized by a relatively conserved quadripartite structure containing a large single copy region of 93,705 bp, a small single copy region of 19,093 bp and two inverted repeat (IR) regions of 19,886 bp. Overall, the genome contained 123 coding regions, of which 15 were repeated in the IR regions. An analysis of chloroplast sequence divergence revealed that the small single copy region was highly variable among the different genera in the Lauraceae family. A total of 40 repeat structures and 83 simple sequence repeats were detected in both the coding and non-coding regions. A phylogenetic analysis indicated that Calycanthus is most closely related to Lauraceae, both being members of Laurales, which forms a sister group to Magnoliids. The complete sequence of the chloroplast of Cinnamomum camphora will aid in in-depth taxonomical studies of the Lauraceae family in the future. The genetic sequence information will also have valuable applications for chloroplast genetic engineering.

“…Previous studies used PCR-based molecular markers to explore the genetic variation potential of rosewood germplasm from various parts of the world. Previous studies explored the genetic diversity of Brazilian rosewood germplasm through RAPD markers [27] and SSR markers [28]. Very recently, Guizado et al [29] for the first time reported the characterization of Peruvian rosewood germplasm with molecular markers (ISSR markers) and confirmed the existence of a good level of genetic diversity in their germplasm.…”

Research studies on conservative genetics of endangered plants are very important to establish the management plans for the conservation of biodiversity. Rosewood is an evergreen tree of the Amazon region and its essential oil has great acceptance in the medical and cosmetic industry. The present study aimed to explore the genetic diversity and population structure of 90 rosewood accessions collected from eight localities of Peruvian Amazon territory through DArTseq markers. A total of 7485 informative markers resulted from genotyping by sequencing (GBS) analysis were used for the molecular characterization of rosewood germplasm. Mean values of various calculated diversity parameters like observed number of alleles (1.962), the effective number of alleles (1.669), unbiased expected heterozygosity (0.411), and percent polymorphism (93.51%) over the entire germplasm showed the existence of a good level of genetic variations. Our results showed that the Mairiricay population was more diverse compared to the rest of the populations. Tamshiyacu-2 and Mairiricay-15 accessions were found genetically distinct accessions. The analysis of molecular variance (AMOVA) reflected maximum variations (75%) are due to differences within populations. The implemented clustering algorithms, i.e., STRUCTURE, neighbor-joining analysis and principal coordinate analysis (PCoA) separated the studied germplasm on the basis of their geographical locations. Diversity indices for STRUCTURE-based populations showed that subpopulation A is more diverse population than the rest of the populations, for such reason, individuals belonging to this subpopulation should be used for reintroduction or reinforcement plans of rosewood conservation. We envisage that molecular characterization of Peruvian rosewood germplasm with DArTseq markers will provide a platform for the conservation, management and restoration of endangered rosewood in upcoming years.
