Genetic and morphological diversity of Moenkhausia oligolepis (Characiformes: Characidae) populations in the tributaries of the Araguaia River, Brazil: implications for taxonomy and conservation
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»

Prediction of maize double-cross hybrids using the best linear unbiased prediction with microsatellite marker information
Authors: M. Balestre, R.G. Von Pinho and J.C. Souza
We examined the usefulness of the best linear unbiased prediction associated with molecular markers for prediction of untested maize double-cross hybrids. Ten single-cross hybrids from different commercial backgrounds were crossed using a complete diallel design. These 10 single-cross hybrids were genotyped with 20 microsatell.. Read More»

Development of CAPS markers to identify Indian tea (Camellia sinensis) clones with high catechin content
Authors: M. Elangbam and A.K. Misra
Tea leaves are rich in plant secondary phenolics, especially flavonoids. Catechins are considered to be the most valuable flavonoids, and the catechin content in tea is an important trait for determining its quality. We have developed cleaved amplified polymorphic sequence (CAPS)-based markers for evaluating total catechin con.. Read More»

Genetic polymorphisms of the FATP1 gene and their associations with meat quality traits in Chinese Qinchuan cattle
Authors: Z.D. Zhao, A.N. Li, S.J. Wei, M.M. Wang, S.J. Li and L.S. Zan
Fatty acid transport protein 1 (FATP1), an integral membrane protein that facilitates long-chain fatty acid influx, is involved in the genetic network for oleic acid synthesis. The aim of this study was to examine the association of FATP1 polymorphisms with live animal meat quality traits in Chinese Qinchuan cattle. Quantitative real-time PCR analysis dem.. Read More»

Pathogenicity for onion and genetic diversity of isolates of the pathogenic fungus Colletotrichum gloeosporioides (Phyllachoraceae) from the State of Pernambuco, Brazil
Authors: M.X. Vila Nova, L.R. Borges, A.C.B. de Sousa, B.T.R.V. Brasileiro, E.A.L.A. Lima, A.F. da Costa and N.T. de Oliveira
Onion anthracnose, caused by Colletotrichum gloeosporioides, is one of the main diseases of onions in the State of Pernambuco. We examined the pathogenicity of 15 C. gloeosporioides strains and analyzed their genetic variability using RAPDs and internal transcribed spacers (ITS) of the rDNA region. Ten of the strains were obta.. 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 the Neotropical tree Hancornia speciosa Gomes in natural populations in Northeastern Brazil
Authors: H.J. Jimenez, L.S.S. Martins, A.V.V. Montarroyos, J.F. Silva Junior, A.L. Alzate-Marin and R.M. Moraes Filho
Mangabeira (Hancornia speciosa Gomes) is a fruit tree of the Apocynaceae family, which is native to Brazil and is a very important food resource for human populations in its areas of occurrence. Mangabeira fruit is collected as an extractive activity, and no domesticated varieties or breeding programs exist. Due to a reduction in the area of ecosystems wh.. Read More»

DNA variation and polymorphism in Tunisian plum species (Prunus spp): contribution of flow cytometry and molecular markers
Authors: H. Ben Tamarzizt, D. Walker, S. Ben Mustapha, D. Abdallah, G. Baraket, A. Salhi Hannachi and S. Zehdi Azzouzi
Plums (Prunus spp) are among the most important stone fruit crops in the world. European (Prunus domestica) and Japanese (Prunus salicina) plums are characterized by different levels of ploidy. Because genetic variability is the prerequisite for any plant-breeding program, we aimed to establish the taxonomic status of Tunisian plums and study their geneti.. Read More»
