Authors: A.L.A. Martinez, J.S.P. Ara�ºjo, C.F. Ragassi, G.S.C. Buso and F.J.B. Reifschneider
Capsicum peppers are native to the Americas, with Brazil being a significant diversity center. Capsicum baccatum accessions at Instituto Federal (IF) Goiano represent a portion of the species genetic resources from central Brazil. We aimed to characterize a C. baccatum working collection comprising 27 accessions and 3 commerci.. Read More»

An optimized protocol for DNA extraction in plants with a high content of secondary metabolites, based on leaves of Mimosa tenuiflora (Willd.) Poir. (Leguminosae)
Authors: S.R. Arruda, D.G. Pereira, M.M. Silva-Castro, M.G. Brito and A.M. Waldschmidt
Some species are characterized by a high content of tannins, alkaloids, and phenols in their leaves. These secondary metabolites are released during DNA extraction and might hinder molecular studies based on PCR (polymerase chain reaction). To provide an efficient method to extract DNA, Mimosa tenuiflora, an important legumino.. Read More»

Association of endothelin-1 gene polymorphisms with essential hypertension in a Chinese population
Authors: Z. Fang, M. Li, Z. Ma and G. Tu
Endothelin-1 (ET-1) is the most potent endogenous vasoconstrictor and is involved in several vascular disorders such as hypertension. Its strong interaction with other vasoactive hormone systems suggests that the ET-1 gene (EDN1) is a potential candidate molecule that influences the risk of developing hypertension. Recently, t..

Identification of Colletotrichum isolates from Capsicum chinense in Amazon
Authors: C.V.S. de Oliveira, K.S. Matos, D.M.C. de Albuquerque, R.E. Hanada and G.F. da Silva
Chili pepper (Capsicum chinense) is a great economic important culture on the State of Amazonas, and it represents, approximately, a production of 1.9 thousand tons per year. It is one of the hosts of Colletotrichum genus in the North region of Brazil. The aim of the study was to differentiate and to identify isolates of Colle.. Read More»

Promoter identification and analysis of key glycosphingolipid biosynthesis-globo series pathway genes in piglets
Authors: W.Y. Qin, L.N. Gan, R.W. Xia, W.H. Dong, S.Y. Sun, G.Q. Zhu,S.L. Wu and W.B. Bao
Glycosphingolipid biosynthesis-globo series pathway genes (FUT1, FUT2, ST3GAL1, HEXA, HEXB, B3GALNT1, and NAGA) play an important regulatory role in the defense against Escherichia coli F18 in piglets. In this study, we identified the transcription initiation site and promoter of this gene cluster by mined previous RNA-seq res.. Read More»

Identification and characterization of the bZIP transcription factor involved in zinc homeostasis in cereals
Authors: A.R. Henriques, D. da R. Farias and A. Costa de Oliveira
Members of the basic leucine zipper family, as bZIP19, are considered to be essential regulators of the adaptation to zinc deficiency. Knowing that this gene as well as its targets are conserved in the plant kingdom, we followed an in silico approach to identify and characterize the bzip19 gene in cereals. Through BLASTp in Ph..

Artificial neural networks as auxiliary tools for the improvement of bean plant architecture
Authors: V.Q. Carneiro, G.N. Silva, C.D. Cruz, P.C.S Carneiro, M. Nascimento and J.E.S. Carneiro
lassification using a scale of visual notes is a strategy used to select erect bean plants in order to improve bean plant architectures. Use of morphological traits associated with the phenotypic expression of bean architecture in classification procedures may enhance selection. The objective of this study was to evaluate the ..

Mechanism of reversal of multidrug resistance by curcumin in human colorectal cancer cell line HCT-8/5-FU
Authors: Y.X. Fan, P. Abulimiti, H.L. Zhang, Y.K. Zhou and L. Zhu
Since there are no studies on the reversal of multidrug resistance by curcumin in the human colorectal cancer cell line HCT-8/5-FU, our aim was to search for highly efficient reversal agents and investigate the underlying mechanisms of this reversal. The cytotoxic effects of curcumin and 5-FU on HCT-8 and HCT-8/5-FU cells and .. Read More»

Generic relationships among Molluginaceae inferred from a molecular phylogenetic analysis of the matK gene
Authors: M.A. Ali, J. Lee and F. Al-Hemaid
The family Molluginaceae (order Caryophyllales) is considered polyphyletic based on the photosynthetic pathway, C4 evolution, and phylogeny of the family. This inference was made based on photosynthetic, anatomical, and molecular datasets. The generic circumscription of this family has greatly been changed owing to the placeme.. Read More»
