Authors: T.J. Domingos, L.N. Moraes, R.M. Moresco, V.P. Margarido and P.C. Venere
Molecular genetic assessments that consider ecological information, in addition to endogamy levels, genetic diversity, and the genetic differentiation among species and populations, are particularly important for the conservation of biological diversity. Prime candidates for conservation genetic review are those subject to hum.. Read More»

Genetic potential of segregating populations of red beans conducted by the bulk method with selection
Authors: J.A.N. Menezes J�ºnior, J.E.S. Carneiro, V.M.P.S. Menezes and P.C.S. Carneiro
This study evaluated the performance and estimated the genetic potential of segregating populations of red bean. Twenty populations of the second cycle of recurrent selection for red bean breeding at Universidade Federal de Viçosa were advanced to the F5 generation in bulk with selection for grain appearance. Population.. Read More»

Genetic diversity and structure of native and non-native populations of the endangered plant Pinus dabeshanensis
Authors: Z.Y. Zhang, H. Wang, W. Chen, X.M. Pang and Y.Y. Li
Owing to a severe decline in its abundance, Pinus dabeshanensis has been listed as an endangered species by the International Union for the Conservation of Nature. Although several restoration events have been undertaken since the 1960s, the natural population genetic structure of this species remains to be investigated. Herei.. Read More»

Differentiation between Triatoma arthurneivai and Triatoma wygodzinskyi (Hemiptera: Reduviidae: Triatominae) using cytotaxonomy
Authors: K.C.C. Alevi, C.H.L. Imperador, F.F.F. Moreira, J. Jurberg and M.T.V. Azeredo-Oliveira
Using classic morphometric techniques to examine the head and thorax of Triatoma specimens, researchers identified a possible taxonomic problem involving T. arthurneivai (Lent & Martins) and T. wygodzinskyi (Lent). A recent geometric morphometric study indicated that the insects captured outside the Serra do Cipó re.. Read More»

Population genetic structure of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), inferred from the mitochondrial A+T-rich region and nuclear ITS2 sequences
Authors: X. Wan, J. Li, M.J. Kim, T.H. Kang, B.R. Jin and I. Kim
The population genetics of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), was characterized using the maternally inherited mitochondrial A+T-rich region and bi-parentally inherited nuclear internal transcribed spacer 2 (ITS2). One hundred and eighty-seven specimens of the rice leaf roller co.. Read More»

Cobalt chloride induces metaphase when topically applied to larvae and pupae of the stingless bee Melipona scutellaris (Hymenoptera, Apidae, Meliponini)
Authors: C. Ueira-Vieira, R.R. Tavares, S. Morelli, B.B. Pereira, R.P. Silva, A.R. Torres-Mariano, W.E. Kerr and A.M. Bonetti
In order to optimize preparations of bee metaphases, we tested cobalt chloride, which has been used as a metaphase inducer in other organisms, such as hamsters and fish. Four microliters of 65 mM cobalt chloride aqueous solution was topically applied to larval and pupal stages of the stingless bee Melipona scutellaris. The cerebral ganglion was removed af..

Phylogenetic relationships of Malayan gaur with other species of the genus Bos based on cytochrome b gene DNA sequences
Authors: M.K.A. Rosli, S.S. Zakaria, S.M.F. Syed-Shabthar, Z.Z. Zainal, M.N. Shukor, M.C. Mahani, O. Abas-Mazni and B.M. Md-Zain
The Malayan gaur (Bos gaurus hubbacki) is one of the three subspecies of gaurs that can be found in Malaysia. We examined the phylogenetic relationships of this subspecies with other species of the genus Bos (B. javanicus, B. indicus, B. taurus, and B. grunniens). The sequence of a key gene, cytochrome b, was compared among 20.. Read More»

HVSI polymorphism indicates multiple origins of mtDNA in the Hazarewal population of Northern Pakistan
Authors: N. Akbar, H. Ahmad, M.S. Nadeem, B.E. Hemphill, K. Muhammad, W. Ahmad and M. Ilyas
Mitochondrial DNA (mtDNA) is an important tool used to explore ethnogenetics and the evolutionary history of human populations. In this study, hypervariable segment I (HVSI) from mtDNA was analyzed to establish the genetic lineage of the Hazarewal populations residing in the Mansehra and Abbottabad districts of Northern Pakist..

Direct preparation protocol to obtain mitotic chromosomes from canine mammary tumors
Authors: C.S.D. Morais, P.R.A.M. Affonso, J.A. Bitencourt and A.A. Wenceslau
Currently, mammary neoplasms in female canines are a serious problem in veterinary clinics. In addition, the canine species is an excellent disease model for human oncology because of the biological and genetic similarities between the species. Cytogenetics has allowed further study of the characterization of neoplasms in canines. We hypothesized that the.. Read More»

The potential of virus-induced gene silencing for speeding up functional characterization of plant genes
Authors: Vagner A. Benedito, Peter B. Visser, Gerco C. Angenent and Frans A. Krens
Virus-induced gene silencing (VIGS) has been shown to be of great potential in plant reverse genetics. Advantages of VIGS over other approaches, such as T-DNA or transposon tagging, include the circumvention of plant transformation, methodological simplicity and robustness, and speedy results. These features make VIGS an attra.. Read More»
