“…There was significant genetic differentiation (P < 0.000) between populations. This variability distribution pattern was different from that found in studies on other species of tropical plants (Rossi, 2007;Rossi et al, 2009;Bertoni et al, 2010;Brandão et al, 2011). However, the same distribution pattern between populations was found in a study carried out by Silva et al (2007), who found high inter-population genetic differentiation between populations of Oryza glumaepatula Steud.…”

“…Therefore, this method is efficient to detect genetic variability within and between populations of T. subincanum. The usefulness of this type of marker has been previously described for both cultivated and wild species (Rossi et al, 2009;Almeida et al, 2009;Brandão et al, 2011). This marker also presents high reproducibility and potential to be used in species without detailed DNA sequence information (Rossi et al, 2009;Almeida et al, 2009;Brandão et al, 2011).…”

“…Among these, inter-simple sequence repeat (ISSR) markers have been widely used in studies of the genetic diversity and variability of wild populations. These markers stand out because they do not need prior information of the DNA sequence, have low development costs, present laboratory procedures with good rates of transferability for other plant species (Bhart et al, 2002), and generate a large number of polymorphic fragments in spite of the low-cost of the technique (Brandão et al, 2011). ISSR markers have proven to be efficient in the many studies on genetic variability of populations that have used them (Cidade et al, 2009;Rossi et al, 2009;Brandão et al, 2011).…”

ABSTRACT. The genus Theobroma, recently reclassified in the family Malvaceae, comprises some species with high economic potential, including the cupuí, Theobroma subincanum Mart., which has not yet been domesticated, and whose genetics and population structure are mostly unknown. This study aimed to assess the population structure and genetic diversity in natural populations of T. subincanum Mart., using inter-simple sequence repeat (ISSR) markers. A total of 59 individuals were sampled in three geographically separate populations, CFA, CMN, and CPT. Nei's genetic distance was estimated to characterize populations with the use of 13 polymorphic primers. The analysis of 4999 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 12 (4): 4998-5006 (2013) Genetic diversity in Theobroma subincana Mart. molecular variance revealed that the variability between populations (51.71%) was higher than that within populations (48.29%). Among the three populations, CPT showed the highest diversity index and percentage of polymorphism. The ISSR molecular markers were efficient and presented sufficient polymorphism to estimate genetic diversity in populations of T. subincanum Mart.

Molecular characterization and population structure study of cambuci: strategy for conservation and genetic improvement

et al. 2016

ABSTRACT. Cambuci (Campomanesia phaea) belongs to the Myrtaceae family and is native to the Atlantic Forest of Brazil. It has ecological and social appeal but is exposed to problems associated with environmental degradation and expansion of agricultural activities in the region. Comprehensive studies on this species are rare, making its conservation and genetic improvement difficult. Thus, it is important to develop research activities to understand the current situation of the species as well as to make recommendations for its conservation and use. This study was performed to characterize the cambuci accessions found in the germplasm bank of Coordenadoria de Assistência Técnica Integral using inter-simple sequence repeat markers, with the goal of understanding the plant's population structure. The results showed the existence of some level of genetic diversity among the cambuci accessions that could be exploited for the genetic improvement of the species. Principal coordinate analysis and discriminant analysis clustered the 80 accessions into three groups, whereas Bayesian modelbased clustering analysis clustered them into two groups. The formation of two cluster groups and the high membership coefficients within the groups pointed out the importance of further collection to cover more areas and more genetic variability within the species. The study also showed the lack of conservation activities; therefore, more attention from the appropriate organizations is needed to plan and implement natural and ex situ conservation activities.

“…Oliveira et al (2014), evaluating the genetic distance among 37 accesses of Psidium spp., using 17 primers, obtained 216 polymorphic fragments, with an average of 13 by primer. Studying the diversity of 272 genotypes of the same species of the jaboticabeira family, Myrcia splendens (SW), Brandão et al (2011) used 10 primers and identified 70 polymorphic fragments. Mani et al (2011), evaluating the genetic distance among 15 species of Psidium spp., used 31 ISSR primers and obtained a total of 234 polymorphic fragments.…”

Molecular Characterization of Jaboticaba Tree Genotypes Located in the Municipalities of Recôncavo of Bahia

ABSTRACT-The jaboticaba tree (Plinia sp.) is a native fruit tree belonging to the Myrtaceae family, which occurs spontaneously throughout Brazil. The estimation of genetic divergence among genotypes of native populations can be useful for conservation and knowledge of available genetic resources, in the formation of gene banks and breeding species. In order to evaluate the genetic diversity of jaboticaba trees identified in the Bahia Reconcavo municipalities, 35 genotypes were characterized by ISSR primers (Inter Simple Sequence Repeats). The 18 primers generated a total of 463 amplicons, and the number of initiator fragments ranged from 14 to 36, with an average of 25.72% and 99.65% polymorphism. Polymorphic information content ranged from 0.13 to 0.33 with a mean of 0.22 and the marker resolution power from 4.34 to 15.77, with an average of 8.67. Multivariate analysis allowed the formation of five groups of genetic divergence, where the longest distance was 0.97 between JCA6 and JSF8 genotypes and the lower of JMT2 and JCA1 (0.11). From the use of ISSR markers it is possible to check the variability between genotypes on the evaluated jaboticaba trees. Index terms: genetic diversity, ISSR, Plinia sp.
