Authors: A.M. Miller, J.E.F. Figueiredo, C.L. Chaves, E.A. Ruas, M.I. Balbi-Pe�±a, N.B. Colauto and L.D. Paccola-Meirelles
Measures to control maize white spot (MWS) caused by Pantoea ananatis are preferentially based on resistant cultivars. A lack of knowledge on the genetic variability of pathogens could interfere with the development and utilization of controlling strategies in this pathosystem. The main goals of this study were to investigate .. Read More»

Genetic variability affecting Exserohilum turcicum resistance in popcorn lines grown under high and low phosphorus conditions
Authors: A.T. Amaral Jr., R.M. Ribeiro, P.H.D. Santos, T.P.S. Poltronieri, J.M.S. Vivas, I.F.S. Gerhardt, B.M. Carvalho, C.S. Freitas and S.B. Miranda
Northern leaf blight (NLB), caused by Exserohilum turcicum, is one of the main foliar diseases that affect popcorn culture. Farmers use many control measures to minimize damage caused by this disease, among which, the use of cultivars with genetic resistance is the most effective and economical. The aim of this study was to in.. Read More»

Proposal of a super trait for the optimum selection of popcorn progenies based on path analysis
Authors: A.T. do Amaral J�ºnior, A. dos Santos, I.F.S. Gerhardt, R.N.F. Kurosawa, N.F. Moreira, M.G. Pereira, G. de A. Gravina and F.H. de L. Silva
A challenge faced by popcorn breeding programs is the existence of a negative correlation between the two main traits, popping expansion and yield, which hinders simultaneous gains. The objective of this study was to investigate the use of a new variable or super trait, which favors the reliable selection of superior progenies.. Read More»

Developing selection criteria based on an ontogenetic path analysis approach to improve grain yield in barley
Authors: T.A. Setotaw, S.G. Belayneh, R. Gwinner and J.L. Ferreira
We used correlation and path coefficient analysis based on an ontogenetic approach to develop selection criteria in barley (Hordeum vulgare L.) for an early production system in Ethiopia. A total of 100 genotypes using 10 x 10-simple lattices with two replications were used to perform the experiment at Ambo and Asasa. The comb.. Read More»

Isolation and characterization of CCoAOMT in interspecific hybrid of Acacia auriculiformis x Acacia mangium - a key gene in lignin biosynthesis
Authors: S.L. Pang, S.S. Ong, H.H. Lee, Z. Zamri, K.I. Kandasamy, C.Y. Choong and R. Wickneswari
This study was directed at the understanding of the function of CCoAOMT isolated from Acacia auriculiformis x Acacia mangium. Full length cDNA of the Acacia hybrid CCoAOMT (AhCCoAOMT) was 1024-bp long, containing 750-bp coding regions, with one major open reading frame of 249 amino .. Read More»

Increased relatedness among the neighboring plants from seedling to adult stages in carna�ºba wax palm
Authors: F.A. Vieira, R.F. Sousa, C.G. Fajardo and M.M. Brand�£o
The objective of this study was to assess the spatial genetic structure (SGS) at different life stages (cohorts) in a remnant population (N = 101) of Copernicia prunifera in the semiarid region of northeastern Brazil. Using seven inter-simple sequence repeat molecular markers, we were able to analyze 93 loci with 100% polymorp.. Read More»

In vivo antimutagenic effects of the Barbados cherry fruit (Malpighia glabra Linnaeus) in a chromosomal aberration assay
Authors: E. D�¼sman, I.V. Almeida, L.T.D. Tonin and V.E.P. Vicentini
Barbados cherry (BC) (Malpighia glabra Linnaeus) is a functional fruit that is consumed to prevent disease. It is used as an adjuvant in the treatment of several diseases, and acts as an antianemic, an appetite stimulant, a wound healer, an anti-inflammatory, a mineralizer, an antifungal, and an antioxidant agent. Several chem.. Read More»

Antigenotoxic and antimutagenic potential of an annatto pigment (norbixin) against oxidative stress
Authors: Antonio C.T.S. JÃ?ºnior, LÃ?Âdia M.B.O. Asad, Eduardo B. de Oliveira, Karla Kovary, Nasser R. Asad and Israel Felzenszwalb
Carotenoids are 40-carbon molecules with conjugated double bonds, making them particularly effective for quenching free radicals. They have always been believed to possess anticancer properties, which could be due to their antioxidant potential. Norbixin is an unusual dicarboxylic water-soluble carotenoid present as a componen.. Read More»

Evidence for a natural hybrid of peacock bass (Cichla monoculus vs Cichla temensis) based on esterase electrophoretic patterns
Authors: Aylton Saturnino Teixeira and Suzana da Silva de Oliveira
Esterase (Est) and esterase-D (Est-D) electrophoretic patterns identified by starch gel electrophoresis of skeletal muscle protein extracts of 184 specimens of three species of peacock bass, locally known as tucunarés (Cichla monoculus, C. temensis and Cichla sp), plus four specimens of a supposed hybrid (C. monoculus v..

Heritability and expected selection response for yield traits in blanched asparagus
Authors: Ileana Gatti, Fernando L�³pez Anido, Vanina Cravero, Pablo Asprelli and Enrique Cointry
Despite the continuous breeding that has been conducted with asparagus (Asparagus officinalis L.) since the beginning of the last century, there is little information on parameters for predicting direct and indirect selection response. Yield traits for blanched asparagus production were studied along a two-year period in a hal.. Read More»
