Selection of common bean genotypes for the Cerrado/Pantanal ecotone via mixed models and multivariate analysis

Authors: A.M. Corr�ªa, M.I.S. Moraes, H.K.A. de Abreu, T. Sharon, C.L.P. de Melo, M.A. Ito, P.E. Teodoro and L.L. Bhering

The common bean, Phaseolus vulgaris, is predominantly grown on small farms and lacks accurate genotype recommendations for specific micro-regions in Brazil. This contributes to a low national average yield. The aim of this study was to use the methods of the harmonic mean of the relative performance of genetic values (HMRPGV) .. Read More»

Use of sugarcane molasses by Pycnoporus sanguineus for the production of laccase for dye decolorization

Authors: R.A. Marim, A.C.C. Oliveira, R.S. Marquezoni, J.P.R. Servantes,B.K. Cardoso, G.A. Linde, N.B. Colauto and J.S. Valle

Pycnoporus sanguineus is a white-rot basidiomycete that produces laccase as the only oxidoreductase; enzyme synthesis depends on cultivation variables, and fungal species and strain. Laccases have wide substrate specificity, oxidize a broad range of compounds, and show potential for use in dye decolorization. We evaluated lacc.. Read More»

Novel genetic male sterility developed in (Capsicum annuum x C. chinense) x C. pubescens and induced by HNO2 showin Mendelian inheritance and aborted at telophase of microspore mother cell stage

Authors: W. Huang, J.-J. Ji, C. Li, G.-Q. Li, C.-C. Yin, W.-G. Chai and Z.-H. Gong

A novel genetic male sterile germplasm was developed by successively crossing of (C. annuum x C. chinense) x C. pubescens and by chemical mutagenesis in pepper. The sterile anthers showed morphological abnormalities, but pistils developed normally with fine pollination capability. We investigated fertility segregation through sib-crossing of the same stra..

Determination of the genetic relationships between wild olive (Olea europaea oleaster) varieties grown in the Aegean region

Authors: M. Sesli and E.D. YeÃ?Â?enoÃ?Â?lu

The RAPD technique was used for determining genetic differences between 12 wild-olive varieties grown in the Aegean provinces of Izmir, Mugla, and Manisa in Turkey. Wild olives obtained from the same provinces were included in the same plot. Twenty of 25 operon primers (OP-I 4, OP-I 14, OP-I 15, OP-I 16, OP-I 17, OP-Q1, OP-Q2,.. Read More»

We determined the expression levels of DREB transcription factor (Gmdreb1) and of the genes Gmgols, Gmpip1b, Gmereb, and Gmdefensin in drought-tolerant (MG/BR46-Conquista) and drought-sensitive (BR16) genotypes of soybean, during drought. The trial was carried out in a controlled-environment chamber, set up to provide drought .. Read More»

Tumor necrosis factor-�± and interleukin-6 gene polymorphism association with susceptibility to celiac disease in Italian patients

Authors: R.M. de Albuquerque Maranh�£o, F.A. Martins Esteves, S. Crovella, L. Segat5 and P.R. Eleut�©rio Souza

The aim of this research was to study polymorphisms in the genes encoding cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in patients with celiac disease (CD) antigens DQ2 (DQ2-positive) or DQ8 (DQ8-positive). We compared the results with healthy controls to determine whether any of the polymorphisms have a role in susceptibil.. Read More»

In silico analysis of gene content in tomato genomic regions mapped to the Ty-2 resistance gene

Authors: Y.F. Liu, H.J. Wan, Y.P. Wei, R.Q. Wang, M.Y. Ruan, Q.J. Ye, Z.M. Li, G.Z. Zhou, Z.P. Yao and Y.J. Yang

Tomato yellow leaf curl virus is one of the main diseases affecting tomato production worldwide. Previous studies have shown that Ty-2 is an important resistance gene located between molecular markers C2_At2g28250 (82.3 cM) and T0302 (89.0 cM), and exhibits strong resistance to tomato yellow leaf curl virus in Asia. In this study, Ty-2 candidate genes wer.. Read More»

Optimizing the efficiency of the touchdown technique for detecting inter-simple sequence repeat markers in corn (Zea mays)

Authors: E.C. Oliveira, A.T. Amaral J�ºnior, L.S.A. Gon�§alves, G.F. Pena, S.P. Freitas J�ºnior, R.M. Ribeiro and M.G. Pereira

We evaluated the efficiency of the touchdown method to determine the ideal PCR conditions for distinct inter-simple sequence repeat primers for processing DNA from common corn, popcorn, sweet corn, and a Tripsacum-maize hybrid. Genomic DNA was extracted from eight accessions of corn: two of the dent type, one Tripsacum-maize h.. Read More»
