“…Genetic variation can be evaluated by using molecular markers, such as inter-simple sequence repeats (ISSRs). ISSR analysis is a simple and efficient technique that does not require previous knowledge of the genome of the taxon under study (Duarte et al 2018;Tian et al 2018;Mariano et al 2019).…”

Cajui (Anacardium spp.) is a native fruit tree (small cashew) of the Brazilian Cerrado and possesses the potential for commercialization. However, cajui exploitation occurs exclusively through extractivism in the absence of conservation strategies. The lack of conservation strategies may lead to a decrease in genetic diversity of Anacardium. In this work, the genetic diversity and population structure of three natural populations in Sete Cidades National Park (PNSC; PI, Brazil) were assessed using ISSR analysis of 56 cajui accessions and two A. occidentale accessions (outgroup) from Pacajus (CE, Brazil). A total of 112 markers were obtained, 93 (83.04%) of which were polymorphic. The diversity indices of these populations indicated moderate levels of genetic diversity. According to AMOVA, 96.17% of the genetic variability lay within populations, with low genetic differentiation among populations (ΦST = 0.03828). Furthermore, STRUCTURE analysis indicated the existence of four connected genetic groups. The findings show that the individuals from the three collection sites did not represent different subpopulations, likely due to the high gene flow (Nm = 6.7) favored by the floral biology of Anacardium, pollinators and small-animal seed dispersers. This research identifies genetically divergent individuals (C-03, C-05, C-22, C-26, C-34 and C-39), which should be considered priority individuals for conservation and can inform conservation programs for Anacardium spp.

Physic nut (Jatropha curcas Linn.) has the potential as a source of sustainable biofuels. Somatic embryo proliferation of J. curcas may cause somaclonal variations. This research aimed to investigate somaclonal variations of J. curcas somatic embryo derived-plantlet using ISSR markers. Somatic embryos of J. curcas at the globular phase were cultured on liquid MS medium supplemented with 0, 0.5, 1.0, 1.5, and 2.0 mg L-1 of 2,4-D. Parameter observed were embryos weight, embryos volume, colour, and size of embryos. After proliferation, the embryos were cultured on a germination medium until the cotyledonary phase. The results showed that proliferation of J. curcas somatic embryos was optimal, with the highest weight and volume, at MS medium added with 1 mg L-1 2,4-D.

“…Determining the genetic variation between J. platyphylla accessions using phenotypic traits and molecular analysis is critical to choosing the parents that will cross paths to generate appropriate populations for breeding purposes [34]. The genetic diversity status of J. platyphylla has not been clear yet.…”
