Molecular identification of variety purity in a cotton hybrid with unknown parentage using DNA-SSR markers
Authors: X.Q. Fu, F.X. Yang, X.K. Lu, X.G. Wang, B.X. Yang, F.J. Liu, Y. Liu and J. Peng
Molecular identification of hybrid purity is difficult in regional trials of cotton varieties and hybrid trials. In particular, the molecular detection of hybrid purity has not yet been reported in the case of unknown parentage. In this study, we screened 5000 pairs of primers and chose 17 pairs of core simple sequence repeat .. Read More»

Prediction of genetic gains by selection indices using mixed models in elephant grass for energy purposes
Authors: V.B. Silva, R F. Daher, M.S.B. Ara?ºjo, Y.P. Souza, S. Cassaro, B.R.S. Menezes, L.M. Gravina, A.A.C. Novo, F.D. Tardin and A.T. Amaral J?ºnior
Genetically improved cultivars of elephant grass need to be adapted to different ecosystems with a faster growth speed and lower seasonality of biomass production over the year. This study aimed to use selection indices using mixed models (REML/BLUP) for selecting families and progenies within full-sib families of elephant gra.. Read More»

Assessment of the rs4340 ACE gene polymorphism in acute coronary syndrome in a Western Mexican population
Authors: A. Valdez-Haro, Y. Valle, E. Valdes-Alvarado, F. Casillas-Mu?±oz, J.F. Mu?±oz-Valle, G.L. Reynoso-Villalpando, H.E. Flores-Salinas and J.R. Padilla-Guti?©rrez
Acute coronary syndrome (ACS) is considered one of the main causes of death worldwide. Contradictory findings concerning the impact of the angiotensin-converting enzyme (ACE) gene on cardiovascular diseases have been reported. Previous conclusions point out that the variability in results depends on ethnicity and genetic polym.. Read More»

Genetic control and combining ability of agronomic attributes and northern leaf blight-related attributes in popcorn
Authors: J.S. Santos, A.T. Amaral J?ºnior, M. Vivas, G.S. Mafra, G.F. Pena,F.H.L. Silva and A.G. Guimar?£es
The present study was conducted to investigate the genetic control and to estimate the general and specific combining abilities of popcorn for agronomic attributes and attributes related to resistance to northern leaf blight (NLB). The 56 hybrids (F1 and reciprocals), together with the eight parent lines and six controls, were.. Read More»

Genetic diversity of Bacillus sp producers of amylase isolated from the soil
Authors: A.R.E.O. Xavier, E.R. Lima, A.M.E. Oliveira, L. Cardoso, J. Santos, C.H.C. Cangussu, L.N. Leite, M.C.L. Quirino, I.G.C. J?ºnior,D.A. Oliveira and M.A.S. Xavier
The microorganisms are the best source of extracellular enzymes since they allow an economical technology with low-resource consumption compared to animals and plants. The amylases are among the most important enzymes being the genus Bacillus one of the most investigated due to its ability to produce this enzyme. The objective.. Read More»

Indices estimated using REML/BLUP and introduction of a super-trait for the selection of progenies in popcorn
Authors: C. Vittorazzi, A.T. Amaral Junior, A.G. Guimar?£es, A.P. Viana, F.H.L. Silva, G.F. Pena, R.F. Daher, I.F.S Gerhardt, G.H.F. Oliveira and M.G. Pereira
Selection indices commonly utilize economic weights, which become arbitrary genetic gains. In popcorn, this is even more evident due to the negative correlation between the main characteristics of economic importance - grain yield and popping expansion. As an option in the use of classical biometrics as a selection index, the .. Read More»

Analysis of melanopsin gene expression in the rabbit retina at different ages
Authors: M.M. Lira-Carrera, B.E. Guti?©rrez-Amavizca, L.J. ?lvarez-Araujo, M. Aguirre-Ram?rez and J.A. P?©rez-Le?³n
Melanopsin is the photopigment of intrinsically photosensitive retinal ganglion cells that mediate non-visual responses to light. The aim of this study was to describe and analyze melanopsin gene expression in the rabbit retina at different ages and compare its expression with the prototypic gene of retinal ganglion cells (Thy..

Genetic diversity of arboreal cotton populations of the Brazilian semiarid: a remnant primary gene pool for cotton cultivars
Authors: I.P.P. de Menezes, L.V. Hoffmann, T.H. de Lima, A.R. da Silva, V.S. Lucena and P.A.V. Barroso
Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, wi.. Read More»

Identification of differentially expressed genes in pathways of cerebral neurotransmission of anovulatory mice
Authors: M.A. Azevedo Jr. and I.D.C.G. Silva
Polycystic ovary syndrome is the classic example of loss of functional cyclicity and anomalous feedback. In this case, the excessive extra-glandular production and conversion of androgens to estrogens are the pathophysiological basis of the chronic anovulation. The literature describes an experimental model of the polymicrocys.. Read More»
