Cytogenetic evidence for de novo synthesis of rRNA and involvement of nucleolar material in the organization of cell structures during spermiogenesis of Chariesterus armatus (Heteroptera, Coreidae)
Authors: R.L.M. Arakaki, H.V. Souza, M.M.U. Castanhole, H.E.M.C. Bicudo and M.M. Itoyama
The nucleolar material of Chariesterus armatus was analyzed during spermiogenesis in cell preparations impregnated with silver nitrate. Nucleolar corpuscles were observed in spermatids at the beginning of the process, showing that this organoid is also maintained after meiosis. In addition, nucleoli were seen in the round sper..

EPSPS variability, gene expression, and enzymatic activity in glyphosate-resistant biotypes of Digitaria insularis
Authors: E. Galeano, A.A.M. Barroso, T.S. Vasconcelos, A. L�³pez-Rubio, A.J.P. Albrecht, R. Victoria Filho and H. Carrer
Weed resistance to herbicides is a natural phenomenon that exerts selection on individuals in a population. In Brazil, glyphosate resistance was recently detected in Digitaria insularis. The objective of this study was to elucidate mechanisms of weed resistance in this plant, including genetic variability, allelism, amino acid substitutions, gene expressi.. Read More»

Targeted gene therapy and in vivo bioluminescent imaging for monitoring postsurgical recurrence and metastasis in mouse models of liver cancer
Authors: Q. He, C.L. Yao, L. Li, Z. Xin, Z.K. Jing and L.X. Li
We investigated the effects of combined targeted gene therapy on recurrence and metastasis after liver cancer resection in nude mice. Twenty BALB/C mice were randomly divided into control and treatment groups with 10 mice in each group and a male/female ratio of 1:1. Luciferase gene-labeled human primary hepatic carcinoma cell line MHCC97-H was then used .. Read More»

Analysis of �Fuji� apple somatic variants from next-generation sequencing
Authors: H.S. Lee1, G.H. Kim1, S.I. Kwon2, J.H. Kim2, Y.S. Kwon2 and C. Choi1
The domesticated apple (Malus x domestica Borkh.) is a major fruit crop of temperate regions of the world. ‘Fuji’ apple (Ralls Genet x Delicious), a famous apple cultivar in Korea, has been very popular since its promotion in Japan in 1958. ‘Fuji’ and its bud mutant cultivars possess variable levels of genetic diversity. Nonetheles.. Read More»

Random regression analysis of test-day milk yields in the first and second lactations of Brazilian Gyr cows
Authors: L.G. Gonzalez-Herrera, L. El Faro, A.B. Bignardi, R.J. Pereira4, C.H.C. Machado and L.G. Albuquerque
The objective of the present study was to estimate the genetic parameters for test-day milk yields (TDMY) in the first and second lactations using random regression models (RRM) in order to contribute to the application of these models in genetic evaluation of milk yield in Gyr cattle. A total of 53,328 TDMY records from 7118 lactations of 5853 Gyr cows w.. Read More»

Characterization of maize genotypes for genetic diversity on the basis of inter simple sequence repeats
Authors: R.W. Muhammad, A. Qayyum, M.Q. Ahmad, A. Hamza, M. Yousaf, B. Ahmad, M. Younas, W. Malik, S. Liaqat, E. Noor
Genetic diversity in crops is essential to make improvements related to superior germplasms. Implementation of molecular markers to identify suitable genotypes speeds up the breeding progress by enhancing selection efficiency. This study was carried out to probe genetic diversity among 21 maize genotypes using 20 inter simple .. Read More»

Evaluation of perfused bovine udder for gene expression studies in dairy cows
Authors: I.S.B. Pinto, I. Fonseca, H.M. Brand�£o, J.C. Gern3, A.S. Guimar�£es, W.A. Carvalho, M.A.V.P. Brito, L.F. Viccini, M.F. Martins
Intramammary infections are one of the main causes of productivity loss in dairy cows. To better understand the immune system response and to avoid the use of live animals, we validated the use of isolated bovine udder as an ex situ model. Six mammary glands were collected from cows ready for culling. Three udders were perfuse.. Read More»

Genetic and molecular characterization of multiflorous spikelet in oat
Authors: C.M. Zimmer, I.P. Ubert, K. Pellizzaro, L.C. Federizzi, I.C. Nava
Multiflorous spikelets are found in several grass species of agricultural and economic interest. In oat, this morphological characteristic is associated with the production of naked grains. Although many genetic studies have been performed over the past century, the inheritance of the multiflorous spikelet trait is not fully u.. Read More»

Fengshui forests conserve genetic diversity: a case study of Phoebe bournei (Hemsl.) Yang in southern China
Authors: Y.J. Ge, Y.J. Liu, A.H. Shen and X.C. Lin
Fengshui forests (sacred groves) are important in traditional Chinese culture and home to many endangered species. These forests may provide protection for some endangered plant species outside the nature reserves, but little is known about their role in genetic conservation. Using inter-simple sequence repeat (ISSR) markers, we compared the genetic diver.. Read More»
