Authors: Y. Sheu, A.S. Cunha-Machado, A.B.P.L. Gontijo, F.C. Favoreto,T.C.B. Soares and F.D. Miranda

The Bromeliaceae family includes a range of species used for many purposes, including ornamental use and use as food, medicine, feed, and fiber. The state of Espírito Santo, Brazil is a center of diversity for this family in the Atlantic Forest. We evaluated the genetic diversity of five populations of the Bromeliaceae .. Read More»

Quaternary origin and genetic divergence of the endemic cactus Mammillaria pectinifera in a changing landscape in the Tehuac�¡n Valley, Mexico

Authors: A. Cornejo-Romero, J. Medina-S�¡nchez, T. Hern�¡ndez-Hern�¡ndez,B. Rend�³n-Aguilar, P.L. Valverde, A. Zavala-Hurtado,S.P. Rivas-Arancibia, M.A. P�©rez-Hern�¡ndez, G. L�³pez-Ortega,C. Jim�©nez-Sierra and C.F. Vargas-Mendoza

The endemic Mexican cactus, Mammillaria pectinifera, shows low dispersal capabilities and isolated populations within the highly dissected landscape of Tehuacán Valley. These characteristics can restrict gene flow and act upon the genetic divergence and speciation in aridplants. We conducted a phylogeographic study to d.. Read More»

Evidence of genetic tolerance to low availability of phosphorus in the soil among genotypes of Coffea canephora

Authors: L.D. Martins, W.N. Rodrigues, L.S. Machado, S.V.B. Brinate, T.V. Colodetti, J.F.T. Amaral and M.A. Tomaz

The expansion of agriculture to new areas in order to increase the competitiveness of coffee producing countries has resulted in cultivation expanding into regions with lower natural fertility. This scenario has created the need to differentiate genotypes of Conilon coffee based on their tolerance to low levels of nutrients in the soil, especially phospho.. Read More»

Molecular and morphological characterization of pomegranate (Punica granatum L.) genotypes sampled from Coruh Valley in Turkey

Authors: E. Orhan, S. Ercisli, A. Esitken and M. Sengul

The pomegranate is one of the oldest fruits that are traditionally consumed by the local inhabitants of the Coruh Valley, Turkey. In this study, the molecular and morphological characteristics of 19 promising pomegranate genotypes selected from the Coruh Valley were evaluated. For the morphological evaluation, 22 quantitative .. Read More»

Karyotypic studies of Cratylia argentea (Desv.) O. Kuntze and C. mollis Mart. ex Benth. (Fabaceae - Papilionoideae)

Authors: S.M. Vargas, G.A. Torres, F.S. Sobrinho, A.V. Pereira, L.C. Davide

Cratylia argentea and C. mollis (Fabaceae-Papilionoideae) are legume shrubs native to the Cerrado and Caatinga, respectively. Both species show great resistance to drought and high nutritive value, which makes them a valuable forage resource in tropical regions. Cytogenetic studies were carried out on accessions of C. argentea.. Read More»

Genetic diversity of Angiopolybia pallens (Lepeletier) (Hymenoptera, Vespidae, Polistinae) explained by the disjunction of South American rainforests

Authors: A.F. Carvalho, G.M.M. Santos, R.S.T. Menezes and M.A. Costa

Angiopolybia pallens is a swarm-founding wasp that occurs in Atlantic and Amazonian rainforests, which have been isolated from each other by a large arid corridor in central Brazil since the Tertiary. In this study, we used data from polymerase chain reaction-restriction fragment length polymorphism of 16S rDNA to infer some a.. Read More»

Assessment of the genetic diversity of tomato yellow leaf curl virus

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

The objective of the present study was to analyze the genetic diversity of tomato yellow leaf curl virus (TYLCV). Representative TYLCV sequences were searched in the National Center for Biotechnology Information database. Comprehensive analysis of TYLCV was performed using bioinformatics by examining gene structure, sequence alignments, phylogeny, GC cont.. Read More»

Development and characterization of polymorphic microsatellite loci in the sea cucumber Holothuria leucospilota

Authors: G. Dai, Z.B. Li, J.B. Shangguan, Y.F. Ning, H.W. Deng,Y. Yuan, Y.S. Huang, H. Yang and J. Lu

Holothuria leucospilota is a tropical holothurian species that is widely distributed in the tropical and sub-tropical India-Western Pacific Region. Eight polymorphic microsatellite loci were developed from H. leucospilota by using the protocol fast isolation by amplified fragment length polymorphism of sequences containing repeats and tested in 30 individ..

Expression of catalase, alcohol dehydrogenase, and malate dehydrogenase in rot grains upon fungicide use on maize hybrids grown at different spacings

Authors: E.R. Kluge, M.C. Mendes, M.V. Faria, H.O. Santos, L.A. Santos and I.E. Sandini

In this study, we evaluated the fungicide effect on the incidence of rot grains and expression of catalase (CAT), alcohol dehydrogenase (ADH), and malate dehydrogenase (MDH) enzymes in commercial maize hybrids grown with conventional and reduced spacing in Guarapuava, PR, Brazil. The experiment was designed in random blocks wi.. Read More»
