Inbreeding effects in Solanum lycocarpum A. St.-Hil populations, an endangered species of the Brazilian Cerrado
Authors: T.M. Moura, M.V.B.M. Siqueira, G.C.X. Oliveira
The inbreeding effective population size is an estimate of inbreeding and genetic drift in populations. It is an important tool for conservation genetics because it represents the number of individuals that are effectively contributing alleles to the subsequent generations. Several studies have been published in the last decad.. Read More»

Spermatogenesis in Triatoma melanocephala (Hemiptera: Triatominae)
Authors: K.C.C. Alevi1, P.P. Mendon�§a1, N.P. Pereira1, J.A. Rosa2 and M.T.V. Azeredo-Oliveira1
Triatoma melanocephala is a rare species of Hemiptera. It belonged to the Brasiliensis subcomplex and presents morphological characteristics very close to those of Triatoma vitticeps. We investigated spermatogenesis of T. melanocephala and compared it with that of T. vitticeps in order to determine whether these organisms have similar cytogenetic characte.. Read More»

Mendelian inheritance, genetic linkage, and genotypic disequilibrium at nine microsatellite loci of Cariniana legalis (Mart.) O. Kuntze
Authors: E.V. Tambarussi1, R. Vencovsky1, M.L.M. Freitas2 and A.M. Sebbenn3
Cariniana legalis is one of the largest tropical trees with a wide distribution in the Brazilian Atlantic rainforest. We investigated the Mendelian inheritance, genetic linkage, and genotypic disequilibrium at seven microsatellite loci specifically isolated for C. legalis, and at two previously developed heterologous microsatellite loci. Forty to 100 open.. Read More»

Cytogenetic and molecular identification of a wheat-Leymus mollis alien multiple substitution line from octoploid Tritileymus x Triticum durum
Authors: Y.H. Pang, J.X. Zhao, W.L. Du, Y.L. Li, J. Wang, L.M. Wang, J. Wu, X.N. Cheng, Q.H. Yang and X.H. Chen
Leymus mollis (Trin.) Pilger (NsNsXmXm, 2n = 28), a wild relative of common wheat, possesses many traits that are potentially valuable for wheat improvement. In order to exploit and utilize the useful genes of L. mollis, we developed a multiple alien substitution line, 10DM50, from the progenies of octoploid Tritileymus M842-1.. Read More»

Phylogenetic classification and clinical aspects of a new putative Deltapapillomavirus associated with skin lesions in cattle
Authors: T.C. Melo, R.F. Carvalho, J. Mazzucchelli-de-Souza, N. Diniz, S. Vasconcelos, S.L.M.R. Assaf, R.P. Araldi, R.M. Ruiz, I. Kerkis, W. Be�§ak and R.C. Stocc
Bovine papillomaviruses (BPVs) are recognized as causal agents of benign and malignant tumors in cattle. Thirteen types of BPVs have already been described and classified into 3 distinct genera. Divergences in the nucleotide sequence of the L1 gene are used to identify new viral types through the employment of PCR assays with .. Read More»

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»

DNA barcoding of arid wild plants using rbcL gene sequences
Authors: S.O. Bafeel, I.A. Arif, M.A. Bakir, A.A. Al Homaidan, A.H. Al Farhan and H.A. Khan
DNA barcoding is currently gaining popularity due to its simplicity and high accuracy as compared to the complexity and subjective biases associated with morphology-based identification of taxa. The standard chloroplast DNA barcode for land plants recommended by the Consortium for the Barcode of Life (CBOL) plant working group.. Read More»

Microsatellite markers for assessing genetic diversity of the medicinal plant Paris polyphylla var. chinensis (Trilliaceae)
Authors: J.Y. Zheng, H. Wang, X.X. Chen, P. Wang, P. Gao, X.N. Li and G.P. Zhu
Paris polyphylla var. chinensis is a perennial herb with medicinal properties that is widely used in traditional Chinese medicine. However, this plant has been on the edge of extinction during the last few decades because of excessive deforestation based on the intense ethnopharmaceutical interest. We isolated 12 microsatellit..

Geoffroy�s side-necked turtle [Phrynops geoffroanus (Schweigger, 1812), Testudines: Chelidae] as a model for evolutionary ecotoxicology: relationship between environmental contamination, conditions and genetic variability
Authors: L.P.R. Venancio, D.A.P.C. Zuccari and C.R. Bonini-Domingos
The objective of this study was to evaluate the role of human activity factors, such as environmental contamination and habitat changes, as drivers for changing the physiological, biochemical, and genetic diversity of Geoffroy’s side-necked turtle populations in one of the most impacted watersheds in southeastern Brazil. The impact of chemical and o.. Read More»

Fine-scale spatial genetic structure of an endangered marsh herb, Caldesia grandis (Alismataceae)
Authors: X.-L. Yue, J.-M. Chen, Y.-H. Guo and Q.-F. Wang2
The endangered marsh herb, Caldesia grandis, is native to China. We investigated the spatial structure of the genetic variation of three populations of C. grandis using RAPD markers and spatial autocorrelation analysis, based on the method of equal distance interval. A total of 157 individuals were sampled from four patches collected from the region of Hu.. Read More»
