Correlations between traits in soybean (Glycine max L.) naturally infected with Asian rust (Phakopsora pachyrhizi)
Authors: B. Rodrigues, F. Serafim, A.P.O. Nogueira, O.T. Hamawaki, L.B. de Sousa and R.L. Hamawaki
Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this stu.. Read More»

Cobalt chloride induces metaphase when topically applied to larvae and pupae of the stingless bee Melipona scutellaris (Hymenoptera, Apidae, Meliponini)
Authors: C. Ueira-Vieira, R.R. Tavares, S. Morelli, B.B. Pereira, R.P. Silva, A.R. Torres-Mariano, W.E. Kerr and A.M. Bonetti
In order to optimize preparations of bee metaphases, we tested cobalt chloride, which has been used as a metaphase inducer in other organisms, such as hamsters and fish. Four microliters of 65 mM cobalt chloride aqueous solution was topically applied to larval and pupal stages of the stingless bee Melipona scutellaris. The cerebral ganglion was removed af..

Expression of human papillomavirus E6 and E7 oncoprotein mRNA in women with low-grade squamous intraepithelial lesions or less
Authors: D.C. Casagrande, J.C.L. Ribalta, K.D.P.F. Leite, M. Schimidt and N.M.D.G. Speck
We verified the prevalence of human papillomavirus (HPV) E6/E7 protein mRNA expression in patients with low-grade squamous intraepithelial lesions (LSILs) and negative cervicovaginal cytology. To investigate the relationship between mRNA expression and viral infection type, we assessed genotyping in single infections. Samples from 825 women were submitted.. Read More»

A network approach predicts NFKBIA and BIRC3 as pathogenic genes in childhood asthma
Authors: X.M. Gao
This study aimed to predict pathogenic genes of childhood asthma based on molecular interaction networks and gene expression data. Known pathogenic genes identified from the human protein-protein interaction network were denoted as seed genes, and were included in network A. We extracted sub-network B (pathogenic network), whi..

Genetic analysis of grain shape and weight after cutting rice husk
Authors: J.R. Fu, L.X. Zhu, X.T. Sun, D.H. Zhou, L.J. Ouyang, J.M. Bian, H.H. He and J. Xu
Grain shape and weight are the most important components of rice yield and are controlled by quantitative trait loci (QTLs). In this study, a double-haploid population, derived from the cross of japonica CJ06 and indica TN1, was used to analyze QTLs for grain shape and weight under two conditions: normal growth with unbroken husk and removing partial husk..

Single nucleotide polymorphisms associated with carcass traits in a population of Brahman and Brahman-influenced steers
Authors: A.M. Royer, C. Shivers, D.G. Riley, M.A. Elzo and M.D. Garcia
Brahman cattle are important in tropical regions due to their ability to tolerate excessive heat and parasites. However, Brahman cattle exhibit lower carcass quality characteristics when compared to Bos taurus breeds. The objective of this study was to evaluate potential associations between single nucleotide polymorphisms (SN.. 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»

Inducing autotetraploids in cassava using oryzalin and colchicine and their in vitro morphophysiological effects
Authors: M. de J. da S. de Carvalho, V.B. Gomes, A. da S. Souza, F.F. Aud, J.A. Santos-Serejo and E.J. Oliveira
Polyploid induction has been used for plant breeding to produce bigger and more robust plants than diploid types. The present study aimed to develop a methodology for in vitro induction of polyploidy in cassava. Apical and lateral microcuttings from the BRS Formosa variety were treated with six oryzalin concentrations for 24 and 48 h. The same methodology.. Read More»

Correlation of androgen receptor and SRD5A2 gene mutations with pediatric hypospadias in 46, XY DSD children
Authors: X.H. Fu, W.Q. Zhang and X.S. Qu
We performed an exploratory study by analyzing the correlation of 46, XY disorders of sex development (46, XY DSD) with androgen receptor (AR) and steroid 5α-reductase-2 (SRD5A2) gene mutations and a safety analysis of dihydrotestosterone (DHT) gel treatment for pediatric micropenis. We collected samples from 76 pediatric patients with 46, XY DSD an.. Read More»

One missense mutation in exon 2 of the PAX5 gene in Iran
Authors: S. Yazdanparast, S.R. Khatami, H. Galehdari and K. Jaseb
The PAX5 gene, which encodes the B-cell specific activator protein, is one of the most important factors in determination of B-cell development. This gene is the main target of somatic mutations in acute B lymphoblastic leukemia (B-ALL). For example, point mutations, deletions, as well as other gene rearrangements may lead to several forms of B-cell malig.. Read More»
