Differential gene expression patterns in the autogamous plant Hordeum euclaston (Poaceae)
Authors: J.E. Georg-Kraemer, C.A.S. Ferreira and S.S. Cavalli
Sib-seedlings of 95 strains of the strictly autogamous grass Hordeum euclaston were analyzed by horizontal polyacrylamide gel electrophoresis for four isoenzyme systems at a specific ontogenetic stage. We found differences in the activity of some genes among individuals of this species. Hence, an ontogenetic analysis was carri.. Read More»

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»

Microbial diversity in Paris polyphylla var. yunnanensis rhizomes of varying ages
Authors: Y. Yang, S.C. Yang, J. Zhao, S. Udikeri and T. Liu
Endophyte microorganisms live inside plants without causing them any apparent damage. Recently, endophytic microorganisms have attracted attention because they can produce bioactive compounds of biotechnological interest. The endophytic microorganisms in Paris polyphylla var. yunnanensis (Liliaceae) - a species used since antiquity in traditional Chinese .. Read More»

Determining the genetic stability of micropropagated sugarcane using inter-simple sequence repeat markers
Authors: B.S. Hsie, J.Z. Brito, M.X. Vila Nova, L.R. Borges-Paluch, M.V. Silva and V.M.S.T. Donato
Sugarcane culture is an important source of income for the Brazilian economy. The aim of this study was to identify somaclonal variation in sugarcane varieties RB943365 and RB92579 arising from micropropagation using inter-simple sequence repeat (ISSR) DNA markers. The evaluated plants were generated from the in vitro propagation of shoot tips grown in MS.. Read More»

Genetic diversity of Vriesea cacuminis (Bromeliaceae): an endangered and endemic Brazilian species
Authors: P.C.C. Ribeiro, L.C. Pinheiro, R. Domingues, R.C. Forzza, M.A. Machado and L.F. Viccini
Data about the genetic structure can help to understand the evolutionary process of natural populations as well as to drive strategies of conservation. Vriesea cacuminis, an endemic Brazilian Bromeliad, has been found in 2 areas of Minas Gerais State. One is a legal preservation unit (Ibitipoca State Park) and the other an unprotected area (Serra Negra). .. Read More»

Phenotypic characteristics for discrimination between advanced genotypes of Brachiaria ruziziensis
Authors: B.A. Rezende, C.B. Ribeiro, D.H.L. Teixeira, F.M.A. Gon�?§alves and F. Souza Sobrinho
The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications. Ten phenotypic characteristics w.. Read More»

Selection for wide adaptability and high phenotypic stability of Brazilian soybean genotypes
Authors: V.M. Oliveira, O.T. Hamawaki, A.O. Nogueira, L.B. Sousa, F.M. Santos and R.L. Hamawaki
Advances in genetic enhancement techniques have led to an increase in soybean production. Thus, soybean is currently one the most economically important cultured species worldwide. The objectives of the present study were to study the interaction of soybean genotypes per environment in terms of grain productivity and to evaluate their phenotypic adaptabil.. Read More»

Molecular genetic map construction and QTL analysis of fruit maturation period in grapevine
Authors: Y.H. Zhao, K. Su, Y.H. Guo, H.F. Ma and X.W. Guo
In this study, we aimed at finding the genetic regularity of grape maturation period. Early-maturing grapevine, “87-1”, was used as the female parent and late-maturing, “9-22”, as the male parent, to create an F1 hybrid population. A total of 149 individual plants and their parents were selected as the .. Read More»

Correlations between traits in soybean (Glycine max L.) naturally infected with Asian rust (Phakopsora pachyrhizi)
Authors: B. Rodrigues, F. Serafim, A.P.O. Nogueira, O.T. Hamawaki, L.B. de Sousa and R.L. Hamawaki
Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this stu.. Read More»

Genetic analysis of grain shape and weight after cutting rice husk
Authors: J.R. Fu, L.X. Zhu, X.T. Sun, D.H. Zhou, L.J. Ouyang, J.M. Bian, H.H. He and J. Xu
Grain shape and weight are the most important components of rice yield and are controlled by quantitative trait loci (QTLs). In this study, a double-haploid population, derived from the cross of japonica CJ06 and indica TN1, was used to analyze QTLs for grain shape and weight under two conditions: normal growth with unbroken husk and removing partial husk..
