The genetic diversity and population structure of Genipa americana L. in Northern Mato Grosso, Brazil
Authors: D.A.C. Ruzza, A.A.B. Rossi, R.B. Bispo, A.V. Tiago, J.S. Cochev, Fernando Saragosa Rossi and J.M. Fernandes
Genipa americana L. (Rubiaceae) is an Amazon region-natural species, which may be subject to inbreeding, since it grows in fragmented environments. The aim of the current study is to assess the genetic diversity and population structure of three G. americana populations naturally grown in Northern Mato Grosso State using SSR m.. Read More»

Development of 21 novel polynucleotide microsatellite markers in a Clithon retropictum (Gastropoda: Neritidae), using next-generation sequencing
Authors: Young Se Hyun, Ha Yeun Song, Min-Seop Kim, Hye Suck An
The neritid species Clithon retropictum (Gastropoda), an oviparous snail, is distributed in freshwater and brackish water in southern Korea, south-east Japan, southern China and Taiwan. This species is listed as a class II endangered species in Korea because of its decreasing population size. It has led to an increase in the n.. Read More»

Genetic diversity of Plathymenia reticulata Benth. in fragments of Atlantic Forest in southeastern Brazil
Authors: L.C. Souza, A.L. Silva J�?ºnior, M.C. Souza, S.H. Kunz and F.D. Miranda
Studies of genetic diversity in natural populations are important for the definition of conservation strategies, especially in populations reduced by processes of fragmentation and continuous forest extraction. Molecular markers stand out as interesting tools for these studies. The objective of this research was to characteriz.. Read More»

Analysis of genetic variability of commercial melon cultivars using SSR molecular markers
Authors: N. Carvalho, F.M. Canela, P.H.S. Leite, M.A. Ferreira, V.R. Oliveira, M.F. Santos, N.O.S. Souza and G.S.C. Buso
Taking into account the scenario of melon production (Cucumis melo L.) in Brazil, it is notable the importance of the culture in the fruit market. The preference of the national market is concentrated in the fruits of the yellow type. Therefore, it is possible that the genetic base of the commercial cultivars is relatively nar.. Read More»

Morphological diversity of cassava accessions of the south-central mesoregion of the State of Mato Grosso, Brazil
Authors: B.W. Zago, M.A.A. Barelli, E.S.S. Hoogerheide, C.L. Corr�?ªa,G.I.S. Delforno and C.J. da Silva
Genetic variability of cassava (Manihot esculenta Crantz) in Brazil is wide, being this the result of natural and cultural selection during pre- and post-domestication of the species in different environments. Given the number of species of the genus found in the region (38 of a total of 98 species), the central region of Braz.. Read More»
