Authors: D.C. Silva, L.E.C. Diniz, A.F. Blank, D.A.C. Nizio, J.A.O. Pinto, K.L.G. Pereira and M.F. Arrigoni-Blank
Eplingiella fruticosa (Salzm. ex Benth.) Harley & J.F.B. Pastore, ex Hyptis fruticosa Salzm. ex Benth. is an aromatic and medicinal plant of the family Lamiaceae, found mainly in regions with intense anthropic activity. Information on the genetic diversity of this species is scarce. However, it can be assessed using molecu.. Read More»

Selection of maize inbred lines and gene expression for resistance to ear rot
Authors: G.S. Pereira, R.G.V. Pinho, E.V.R.V. Pinho, L.P.M. Pires, L.A.Y. Bernardo Junior, J.L.A. Pereira and M.P. Melo
In recent years, there has been a large incidence of fungi causing “ear rot” in maize in Brazil, the main fungus being Fusarium verticillioides. The most efficient and competitive alternative for control of this disease consists of using maize hybrids resistant to this pathogen. Thus, the aims of this study were to.. Read More»

Genetic variability and phylogenetic aspects in species of the genus Macrobrachium
Authors: A.L. Guerra, A.V.B. Lima, R.V. Lucato J�ºnior, M.C. Chiachio, F.G. Taddei and L. Castiglioni
The genus Macrobrachium includes prawns, which are widely distributed in lakes, floodplains, and rivers in tropical and subtropical regions of South America. This genus presents nearly 210 known species with great ecological and economic importance. However, few studies are related to the biology of these crustaceans. In this .. Read More»

Association of SIRT2 gene polymorphisms with body measurement and growth traits of Qinchuan cattle
Authors: L.S. Gui, W.C. Yang, C.P. Zhao, S.J. Wei, Z.D. Zhao and L.S. Zan
Silent information regulator 2 (SIRT2), a member of the Sirtuin family of class III nicotinamide adenine dinucleotide-dependent protein deacetylases, plays an important role in senescence, metabolism, and apoptosis. This study was conducted to detect potential polymorphisms of the bovine SIRT2 gene and explore their relationships with meat quality and bod.. Read More»

Genetic diversity of locally adapted sheep from Pantanal region of Mato Grosso do Sul
Authors: B.A. Crispim1, A.B. Grisolia1, L.O. Seno2, A.A. Egito3, F.M. Vargas Junior2 and M.R. Souza2
Sheep of the Pantaneiro breed and seven other breeds, raised in the State of Mato Grosso do Sul, Brazil, were genotyped using eight microsatellite loci. The aim of the present study was to determine the genetic variability, phylogenetic relationship, and patterns of gene introgression and miscegenation among the animals surveyed, to obtain information abo..

Population variability of Bemisia tabaci (Genn.) in different hosts
Authors: G.E. do Valle, A.L. Louren�§�£o, M.I. Zucchi, J.B. Pinheiro and A.G. de Abreu
The silverleaf whitefly, Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae), is a cryptic species complex that contains some of the most damaging pests in tropical and subtropical regions. Recent studies have indicated that this complex is composed of at least 24 distinct and morphologically indistinguishable species that mainly differ in their ability to tr.. Read More»

Genetic diversity of spineless Cereus jamacaru accessions using morphological and molecular markers
Authors: F.I.C. Oliveira, P.N. Bordallo, A.C.R. Castro and D. Correia
This is the first study to examine the genetic diversity of mandacaru cactus (Cereus jamacaru P. DC.). Plants of spineless mandacaru are commonly found in gardens and parks of urban areas in northeastern Brazil. In addition to exploring their ornamental potential, morphological, and genetic characterization may contribute to the development of plant mater.. Read More»

Establishment and molecular characterization of a sweet potato germplasm bank of the highlands of Paran�¡ State, Brazil
Authors: L.K.P. Camargo1,2, A.F. M�³gor2, J.T.V. Resende1 and P.R. Da-Silva3
The sweet potato (Ipomoea batatas L.) is a crop of great importance in developing countries, as a food staple, for animal feed, and potentially for biofuel. Development of cultivars adapted to specific regions within these countries would be useful. To start a breeding program, the first step is the establishment of a germplasm bank. We initiated a sweet .. Read More»

Genetic differences between the wild and hatchery-produced populations of Korean short barbeled grunter (Hapalogenys nitens) determined with microsatellite markers
Authors: H.S. An, H.W. Kang, H.S. Han, J.Y. Park, C.G. Hong, J. Park, J.I. Myeong and C.M. An
Short barbeled grunter, Hapalogenys nitens, is an economically important fishery resource. In Korea, this fish is in the early stage of domestication, and it has been regarded as the candidate marine fish species for prospective aquaculture diversification. This study presents a preliminary investigation of the future viability of sustainable fry producti.. Read More»

Use of morpho-agronomic traits and DNA profiling for classification of genetic diversity in papaya
Authors: O.N. de Jesus, J.P.X. de Freitas, J.L.L. Dantas and E.J. de Oliveira
We examined the genetic diversity of papaya (Carica papaya) based on morpho-agronomic and molecular data. Twenty-seven genotypes grown in Brazil were analyzed with 11 AFLP primer combinations, 23 ISSR markers, 22 qualitative, and 30 quantitative descriptors. For the joint analyses, we used the Gower algorithm (Joint Gower) and the average value of the ind.. Read More»
