Molecular mapping and candidate gene analysis for resistance to powdery mildew in Cucumis sativus stem
Authors: P.N. Liu, H. Miao, H.W. Lu, J.Y. Cui, G.L. Tian, T.C. Wehner, X.F. Gu and S.P. Zhang
Powdery mildew (PM) of cucumber (Cucumis sativus), caused by Podosphaera xanthii, is a major foliar disease worldwide and resistance is one of the main objectives in cucumber breeding programs. The resistance to PM in cucumber stem is important to the resistance for the whole plant. In this study, genetic analysis and gene map.. Read More»

Characterization of a pepper collection (Capsicum frutescens L.) from Brazil
Authors: M.F. Lima, S.I.C. Carvalho, C.F. Ragassi, L.B. Bianchetti, F.G. Faleiro and F.J.B. Reifschneider
Germplasm banks are essential as sources of genetic variability for plant breeding programs. To characterize a Brazilian Capsicum frutescens collection, 21 malagueta and 5 Tabasco hot pepper accessions were evaluated under field and greenhouse conditions regarding morphological and molecular traits, as well as resistance to vi..

A Xanthomonas citri subsp citri hypothetical protein related to virulence contains a non-functional HD domain and is implicated in flagellar motility
Authors: F.C.F. Vieira, A.M. Gon�?§alves, E.F.R. Mendoza, R.M. Ferreira, M.L.M. Costa, T.S. Balbuena, H.G. Sebinelli, P. Ciancaglini, J.M. Pizauro Junior and J.A. Ferro
Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp citri (Xac), severely affects most economically important citrus varieties worldwide. A previous study showed that disruption of the ORF XAC1201 from the Xac 306 strain by transposon Tn5 decreased bacterium virulence in the Rangpur lime host (Citrus l.. Read More»

ITS2 as a molecular marker for the identification of Diatraea saccharalis and D. flavipennella and possible infection with Cotesia spp
Authors: M.S. Regueira Neto, R.P. Barros, M.A.J. Morais, V.Q. Balbino and V. Loreto
In Brazil, the species Diatraea flavipennella and D. saccharalis play an important role in the sugar and alcohol agribusiness by causing many damages in sugarcane fields. The egg, larva, pupa, and adult stages are very morphologically similar between these species, and the identification can be confused. The internal transcribed spacer 2 (ITS 2) from ribo.. Read More»

Genetic improvement is essential to achieve increments in maize (Zea mays L.) grain yield components. It may be obtained through crosses, which enable to exploit the effects of intervarietal heterosis, allelic complementarity, as well as gene actions and effects. This study estimated the components of variance and genetic para.. Read More»

Analysis of genetic variability of commercial melon cultivars using SSR molecular markers
Authors: N. Carvalho, F.M. Canela, P.H.S. Leite, M.A. Ferreira, V.R. Oliveira, M.F. Santos, N.O.S. Souza and G.S.C. Buso
Taking into account the scenario of melon production (Cucumis melo L.) in Brazil, it is notable the importance of the culture in the fruit market. The preference of the national market is concentrated in the fruits of the yellow type. Therefore, it is possible that the genetic base of the commercial cultivars is relatively nar.. Read More»

Mutational screening in the LDLR gene among patients presenting familial hypercholesterolemia in the Southeast of Brazil
Authors: G.A. Molfetta, D.L. Zanette, J.E. Santos and W.A. Silva Jr
Familial hypercholesterolemia (FH) is a dominant, autosomal disease characterized by high LDL levels in blood plasma, and is caused by a defect in the gene encoding the LDL receptor (LDLR). The clinical diagnosis is based on personal and familial history, physical examination findings, and measures of high LDL cholesterol conc.. Read More»

Morphological diversity of cassava accessions of the south-central mesoregion of the State of Mato Grosso, Brazil
Authors: B.W. Zago, M.A.A. Barelli, E.S.S. Hoogerheide, C.L. Corr�?ªa,G.I.S. Delforno and C.J. da Silva
Genetic variability of cassava (Manihot esculenta Crantz) in Brazil is wide, being this the result of natural and cultural selection during pre- and post-domestication of the species in different environments. Given the number of species of the genus found in the region (38 of a total of 98 species), the central region of Braz.. Read More»
