Authors: S. de M. Steckling, N.D. Ribeiro, F.D. Arns, H.C. Mezzomo, M.T.D.F. Possobom
The development of common bean cultivars with high technological quality that are biofortified with minerals, is required to meet the demand for food with health benefits. The objectives of this study were to evaluate whether common bean genotypes differ in terms of technological and mineral biofortification traits, to study t.. Read More»

REML/BLUP and sequential path analysis in estimating genotypic values and interrelationships among simple maize grain yield-related traits
Authors: T. Olivoto, M. Nardino, I.R. Carvalho3, D.N. Follmann4, M. Ferrari3, V.J. Szareski5, A.J. de Pelegrin3 and V.Q. de Souza6
Methodologies using restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) in combination with sequential path analysis in maize are still limited in the literature. Therefore, the aims of this study were: i) to use REML/BLUP-based procedures in order to estimate variance components, genetic parameters, and .. Read More»

Multi-trait BLUP model indicates sorghum hybrids with genetic potential for agronomic and nutritional traits
Authors: J.E. Almeida Filho, F.D. Tardin, J.F.R. Guimar�£es, M.D.V. Resende, F.F. Silva, M.L. Simeone, C.B. Menezes and V.A.V. Queiroz
The breeding of sorghum, Sorghum bicolor (L.) Moench, aimed at improving its nutritional quality, is of great interest, since it can be used as a highly nutritive alternative food source and can possibly be cultivated in regions with low rainfall. The objective of the present study was to evaluate the potential and genetic diversity of grain-sorghum hybri.. Read More»

Characterization of Chinese eggplant isolates of the fungal pathogen Verticillium dahliae from different geographic origins
Authors: Z. Xu Z. Ali X. Hou H. Li J.X. Yi P.A. Abbasi
Verticillium dahliae is a fungal pathogen that causes wilt disease in a wide range of host plants. Characterization of virulence, morphological, and molecular variations among V. dahliae isolates from different geographic origins is essential for any breeding program aimed at producing plant cultivars resistant to this disease. We characterized virulence var.. Read More»

Effect of puerarin on the expression of NMU, NPY, and POMC genes in the hypothalamus
Authors: Q.D. Jiang1,2 and X.P. Li1
The hypothalamus is an important component of the nervous system, and neuropeptide Y (NPY), proopiomelanocortin (POMC), and neuromedin U (NMU) are key players in physiological regulation. Puerarin is important for nerve regulation. We investigated the effect of puerarin on the expression of NMU, NPY, and POMC genes in the hypothalamus. The results showed .. Read More»

Efficient isolation of high-quality RNA from lotus Nelumbo nucifera ssp nucifera tissues
Authors: Y.J. Zhang X.Y. Hao Z.S. Liang W.D. Ke H.B. Guo
Nelumbo nucifera is widely used as food, as an ornamental, in medicine, and as packing material; it is also reported to have anti-HIV effects and antioxidant capacity. We sought an improved method for extracting high-quality total RNA from different tissues of N. nucifera. Four methods for RNA extraction were assessed for their ability to recover high-qua..

Epistasis in intra- and inter-gene pool crosses of the common bean
Authors: J.C. Borel1, M.A.P. Ramalho2 and A.F.B. Abreu3
Epistasis has been shown to have an important role in the genetic control of several quantitative traits in the common bean. This study aimed to investigate the occurrence of epistasis in intra- and inter-pool gene crosses of the common bean. Four elite lines adapted to Brazilian conditions were used as parents, two from the Andean gene pool (ESAL 686; BR.. Read More»

Investigation of mycoviruses in endophytic and phytopathogenic strains of Colletotrichum from different hosts
Authors: P. Rosseto1, A.T. Costa1, J.C. Polonio1, A.A. da Silva1, J.A. Pamphile1and J.L. Azevedo2
Fungi belonging to the Colletotrichum genus can be categorized as endophytic or phytopathogenic. These fungi can be infected by viruses, termed mycoviruses, which are know to promote hypovirulence in infected fungi. However, there are few studies that have described mycoviral infections of endophytes. The production of secondary metabolites by endophytes .. Read More»

Salt stress alters DNA methylation levels in alfalfa (Medicago spp)
Authors: A. Al-Lawati1, S. Al-Bahry1, R. Victor1, A.H. Al-Lawati2 and M.W. Yaish1
Modification of DNA methylation status is one of the mechanisms used by plants to adjust gene expression at both the transcriptional and posttranscriptional levels when plants are exposed to suboptimal conditions. Under abiotic stress, different cultivars often show heritable phenotypic variation accompanied by epigenetic polymorphisms at the DNA methylat.. Read More»
