Authors: D.N. Follmann, A. Cargnelutti Filho, A.D. L�ºcio, V.Q. de Souza, M. Caraffa, C.A. Wartha
The State of Rio Grande do Sul (RS) stands out as the largest wheat producer in Brazil. Wheat is the most emphasized winter cereal in RS, attracting public and private investments directed to wheat genetic breeding. The study of genetic progress should be performed routinely at breeding programs to study the behavior of cultiv.. Read More»

Genetic diversity and molecular characterization of several Heliconia species in Colombia
Authors: L. Isaza M.L. Marulanda A.M. L�³pez
Researchers have classified the Heliconia genus as a group of highly variable and diverse plants. Species and cultivars are visually differentiated primarily on the basis of the color and size of inflorescence bracts. At taxonomic level, flower type (parabolic, sigmoid, or erect) and size are taken into account. The vast morphological diversity of helicon.. Read More»

Expression of drought tolerance genes in tropical upland rice cultivars (Oryza sativa)
Authors: R.D.D. Silveira, F.R.M. Abreu, S. Mamidi, P.E. McClean, R.P. Vianello, A.C. Lanna, N.P. Carneiro and C. Brondani
Gene expression related to drought response in the leaf tissues of two Brazilian upland cultivars, the drought-tolerant Douradão and the drought-sensitive Primavera, was analyzed. RNA-seq identified 27,618 transcripts in the Douradão cultivar, with 24,090 (87.2%) homologous to the rice database, and 27,221 transcripts in the Primavera cultiv.. Read More»

Effect of generations and environments in the analysis of a partial diallel to improve bean earliness
Authors: N.M. Vale, L.D. Barili, M.H. Souza, L.M.M. Moura, J.E.S. Carneiro, P.C. Carneiro and F.L. Silva
The objective of this study was to select genitors based on F1 and F2 generations, evaluated in different environments, to obtain segregating populations for the identification of strains showing improved earliness, yield, and carioca-type grains. Nine bean strains were crossed in a partial diallel scheme (4 x 5), in which group 1 included 4 strains with .. Read More»

Gene expression of coffee seed oxidation and germination processes during drying
Authors: G.C. Santos, E.V.R. von Pinho and S.D.V.F. Rosa
Coffee (Coffea arabica L.) seeds are sensitive to desiccation and oxidative stress during drying processes. We investigated the effect of drying and moisture levels on germination-related gene expressions associated with enzymatic systems that prevent oxidative stress in coffee seeds. Coffee seeds collected at physiological maturity were subjected to slow.. Read More»

Evaluation of progenies from the fifth reciprocal recurrent selection cycle in maize
Authors: N.B. Alves, J.M.V. P�¡dua, K.O.G. Dias, R.P. Diniz, M.L. Guedes, G.A. Cardoso and J.C. Souza
The objective of this study was to evaluate the performance of 119 full sib progenies of the fifth cycle of reciprocal recurrent selection (RRS) derived from of Universidade Federal de Lavras maize breeding program. The experiment was carried out in an 11 x 11 triple lattice design at two locations (Lavras, Lambari). The plots consisted of two rows of 3 m.. Read More»

Effect of overexpression of citrus 9-cis-epoxycarotenoid dioxygenase 3 (CsNCED3) on the physiological response to drought stress in transgenic tobacco
Authors: A.M. Pedrosa, L.C. Cidade, C.P.S. Martins, A.F. Macedo, D.M. Neves, F.P. Gomes, E.I.S. Floh, M.G.C. Costa
9-cis-epoxycarotenoid dioxygenase (NCED) encodes a key enzyme in abscisic acid (ABA) biosynthesis. Little is known regarding the regulation of stress response by NCEDs at physiological levels. In the present study, we generated transgenic tobacco overexpressing an NCED3 ortholog from citrus (CsNCED3) and investigated its relev.. Read More»

Expression of LTP genes in response to saline stress in rice seedlings
Authors: G.P. Moraes, L.C. Benitez, M.N. do Amaral, I.L. Vighi, P.A. Auler, L.C da Maia, V.J. Bianchi and E.J.B. Braga
Saline stress is one of the primary factors limiting increased rice productivity in the southern region of Brazil. Farming can be affected by salinity that is due to both the origin of the soils as well as the irrigation water. Lipid transfer proteins (LTPs) have many physiological functions, including in the response to saline stress. Therefore, the obje.. Read More»

Leaf transcriptome analysis and development of SSR markers in water chestnut (Eleocharis dulcis)
Authors: H.B. Liu, Y.N. You, Z.X. Zhu, X.F. Zheng, J.B. Huang, Z.L. Hu and Y. Diao
Water chestnut (Eleocharis dulcis) is an important aquatic crop in China; however, transcriptomic and genomic data in public databases are limited. To identify genes and development molecular markers, high-throughput transcriptome sequencing was applied to generate transcript sequences from water chestnut leaf. More than 24 million reads were obtained, tr.. Read More»
