Authors: G.B. Dias, V.M. Gomes, T.M.S. Moraes, U.P. Zottich, G.R. Rabelo, A.O. Carvalho, M. Moulin, L.S.A. Gon�§alves, R. Rodrigues and M. Da Cunha
Capsicum species are frequently described in terms of genetic divergence, considering morphological, agronomic, and molecular databases. However, descriptions of genetic differences based on anatomical characters are rare. We examined the anatomy and the micromorphology of vegetative and reproductive organs of several Capsicum species. Four Capsicum acces.. Read More»

Simple sequence repeat-based association analysis of fruit traits in eggplant (Solanum melongena)
Authors: H.Y. Ge1, Y. Liu1, J. Zhang2, H.Q. Han1, H.Z. Li1, W.T. Shao1 and H.Y. Chen1
Association mapping based on linkage disequilibrium (LD) provides a promising tool to identify quantitative trait loci (QTLs) in plant resources. A total of 141 eggplant (Solanum melongena L.) accessions were selected to detect simple sequence repeat (SSR) markers associated with nine fruit traits. Population structure analysis was performed with 105 SSR .. Read More»

Selection of high heterozygosity popcorn varieties in Brazil based on SSR markers
Authors: I.B.O. Eloi, C.A. Mangolin, C.A. Scapim, C.S. Gon�§alves and M.F.P.S. Machado
We analyzed genetic structure and diversity among eight populations of popcorn, using SSR loci as genetic markers. Our objectives were to select SSR loci that could be used to estimate genetic diversity within popcorn populations, and to analyze the genetic structure of promising populations with high levels of heterozygosity ..

Mendelian inheritance, linkage and genotypic disequilibrium in microsatellite loci isolated from Hymenaea courbaril (Leguminosae)
Authors: F.S. Carneiro, A.E.B. Lacerda, M.R. Lemes, R. Gribel, M. Kanashiro and A.M. Sebbenn
The Neotropical tree Hymenaea courbaril, locally known as Jatobá, is a valuable source of lumber and also produces comestible and medicinal fruit. We characterized Mendelian inheritance, linkage and genotypic disequilibrium at nine microsatellite loci isolated from H. courbaril, in order to determine if they would provi.. Read More»

Morphological and genetic characteristics of hybrid combinations of Dactylis glomerata
Authors: Y.F. Zhao, X.Q. Zhang, X. Ma, W.G. Xie and L.K. Huang
Six F1 populations derived from crosses among 4 orchardgrass (Dactylis glomerata L.) cultivars were studied by morphological and simple sequence repeat molecular markers to test for hybrid vigor and a correlation between genetic distance and heterosis. Heterosis was observed for days to length of culm, leaf traits, tiller numb.. Read More»

Thirty-four Musa (Musaceae) expressed sequence tag-derived microsatellite markers transferred to Musella lasiocarpa
Authors: W.J. Li, H. Ma, Z.H. Li, Y.M. Wan, X.X. Liu and C.L. Zhou
We assembled 31,308 publicly available Musa EST sequences into 21,129 unigenes; 4944 of them contained 5416 SSR motifs. In all, 238 unigenes flanking SSRs were randomly selected for primer design and then tested for amplification in Musella lasiocarpa. Seventy-eight primer pairs were found to be transferable to this species, and 49 displayed polymorphism... Read More»

Population structure and genetic diversity in natural populations of Theobroma speciosum Willd. Ex Spreng (Malvaceae)
Authors: L.D. Giustina, L.N. Luz, F.S. Vieira, F.S. Rossi, C.R.A. Soares-Lopes, T.N.S. Pereira and A.A.B. Rossi
The genus Theobroma found in the Amazon region is composed of 22 species, including Theobroma speciosum, better known as cacauí. These species are constantly threatened by forest fragmentation caused by human activities and require conservation strategies and management aimed at preserving them in their natural environm..

Identification of hybrids between triticale and Aegilops juvenalis (Thell.) Eig and determination of genetic similarity with ISSRs
Authors: A. Gradzielewska, D. Gruszecka, J. LeÃ?Â?niowska-Nowak and E. Paczos-GrzÃ?Â?da
Wide hybridization expands the gene pool of cultivated species and can produce genotypes with practical value, often resistant to diseases. In plants, ISSRs are often used for hybrid identification as well as for diversity evaluation. We estimated genetic similarity among advanced genetic stocks of triticale hybrids and identified Aegilops juvenalis intro.. Read More»

Characterization of nine microsatellite loci for the tree species Parapiptadenia rigida (Fabaceae-Mimosoideae) and their transferability
Authors: B.F. Costa, L.A. Rodrigues, E.A. Ruas, L.B. Souza, C.F. Ruas, B.G. Vieira, A.R.O. Conson and P.M. Ruas
Parapiptadenia rigida, locally known as angico, is a tropical tree common in the semideciduous Brazilian forest. Its wood is naturally resistant to insect attack and is useful for construction. Extracts from the tree have medicinal properties. We characterized nine microsatellite loci for P. rigida. Thirty-five alleles were detected in a sample of 45 indi.. Read More»

Mapping of HtNB, a gene conferring non-lesion resistance before heading to Exserohilum turcicum (Pass.), in a maize inbred line derived from the Indonesian variety Bramadi
Authors: H. Wang, Z.X. Xiao, F.G. Wang, Y.N. Xiao, J.R. Zhao, Y.L. Zheng and F.Z. Qiu
The gene HtNB confers non-lesion resistance to the fungal pathogen Exserohilum turcicum in maize. To map this gene, we developed two F2 populations, P111 (resistant line) x HuangZao 4 (susceptible line) and P111 x B73 (susceptible). HtNB was located on chromosome 8.07 bin, flanked by MAC216826-4 and umc2218 at distances of 3.3 and 3.4 cM, respectively. Ht.. Read More»
