Conservation; Genetic variability; Harvesting; ISSR

Maytenus truncata (Celastraceae) is a plant species widely used in the treatment of ulcers and tumors. Despite the intensive harvest of native specimens in the State of Bahia, northeastern Brazil, there is no information about the genetic variability or structure of this species. Therefore, the goal of this study was to estimate the genetic diversity and population structure of ... more

Allium cepa L; Genetic characterization; Heterozygosity; Polymorphism; SSR marker

The five most common cultivars from the genus Allium cepa L. in Bosnia and Herzegovina (BiH) were analysed, focusing on Konjic onion. Seven SSR markers for genetic similarity analysis were used to address the genetic backgrounds. The polymorphic relationship between the SSR markers was analyzed by using Polymorphic Information Content (PIC) and Heterozygosity (H) ... more

Anthonomus grandis; Body length; Heterozygosity; Morphometric marker; Prothorax width

The boll weevil, Anthonomus grandis (Curculionidae) is the main pest of cotton culture. To establish more efficient forms of control, it is important to understand its genetic structure and the diversity of its populations. We examined the genetic diversity of various populations of boll weevils, collected from several Brazilian locations, through ... more

Genetic diversity; Inter-simple sequence repeat; Kernel apricot; Simple sequence repeat

Simple sequence repeat (SSR) and inter-simple sequence repeat (ISSR) markers were used to evaluate genetic diversity among 22 sweet kernel apricot accessions and 12 cultivars in China to provide information on how to improve the utilization of kernel apricot germplasms. The results showed that 10 pairs of SSR primers screened from 40 primer pairs amplified 43 allelic variants, all of which ... more

Asian corn borer; Beauveria bassiana; Genetic distance; Inter-simple sequence repeat; Molecular tracing; Population genetic structure

Beauveria bassiana is a soil fungus that parasitizes arthropod species, and is used to control the Asian corn borer in Northeast China. In this study, B. bassiana was investigated in Xiaoxian County and Baicheng City, and the results were compared with those of Gongzhuling City, where the fungus was not applied. Using the inter-simple sequence repeat (ISSR) ... more

Conservation strategy; Genetic structure; Inter-simple sequence repeat; Wild soybean

Knowledge of the spatial patterns of genetic variation in wild populations has significant implications for in situ conservation and the determination of conservation order. To study the levels of genetic diversity, spatial genetic structures, and genetic distances in Glycine soja, 11 natural populations in northern China were analyzed by estimating genetic coefficients ... more

Capparis spinosa L.; Genetic diversity; Inter-simple sequence repeat

Capparis spinosa L. is an important medicinal species in the Xinjiang Province of China. Ten natural populations of C. spinosa from 3 locations in North, Central, and South Xinjiang were studied using morphological trait inter simple sequence repeat (ISSR) molecular markers to assess the genetic diversity and population structure. In this study, the 10 ISSR primers ... more

Atlantic Forest; Bromeliads; Genetic diversity; Inter-simple sequence repeat; Natural populations

Bromeliads are greatly represented in the Atlantic Forest, although many species are threatened with extinction owing to habitat fragmentation and intense extraction for ornamental purposes. Therefore, it is necessary to conduct studies generating knowledge about genetic diversity and the distribution of this diversity among and within natural populations to establish conservation strategies. ... more

Genetic variability; Microsatellites; Molecular characterization; Musa spp

Microsatellite markers have been widely used in the quantification of genetic variability and for genetic breeding in Musa spp. The objective of the present study was to evaluate the discriminatory power of microsatellite markers derived from ‘Calcutta 4’ and ‘Ouro’ genomic libraries, and to analyze the genetic variability among 30 banana accessions. Thirty-eight markers were ... more

Cacauí; Cupuí; Genetic variability; Theobroma speciosum; Theobroma subincanum

Several species within the genus Theobroma have particularly high economic value, including T. cacao and T. grandiflorum. Other species in this genus, such as T. speciosum and T. subincanum, have potential value for use in the conservation of genetic diversity in breeding programs. These latter species could also be domesticated or improved to ... more
