Proposed method for dimensionality reduction based on framework in gene expression domain
Authors: D.C. Macedo, E.C.M. Ishikawa, C.B. Santos, S.N. Matos, H.B. Borges and A.C. Francisco
The excessive use of attributes may affect the search for patterns and extraction of useful knowledge, because they harm the learning performance of algorithms in both speed and success rate. The use of dimensionality reduction methods is therefore an important alternative; however, these methods do not deal with the reduction of attributes in a specific .. Read More»

Isolation and characterization of microsatellite markers for Amomum tsaoko (Zingiberaceae), an economically important plant in China
Authors: Y.-W. Yang1, Z.-Y. Yang2, M.-R. Yan1, Z.-G. Qian1 and K.-Y. Guan2
Twenty-four microsatellite markers were isolated from the genomic DNA of Amomum tsaoko Crevost et Lemaire, an important economic plant in China, using the method fast isolation by AFLP of sequences containing repeats (FIASCO). Polymorphism within each locus was assessed in 60 individuals from three populations in Yunnan Province, China, and nine of them w.. Read More»

Physical wounding and ethylene stimulated embryogenic stem cell proliferation and plantlet regeneration in protocorm-like bodies of Phalaenopsis orchids...
Authors: Y.-W. Huang1, Y.-J. Tsai2, T.-C. Cheng2, J.-J. Chen3 and F.-C. Chen...
Phalaenopsis orchids have been regenerated by inducing protocorm-like bodies (PLBs) from etiolated leaf sections. However, the physiological and molecular mechanisms of secondary PLB development and subsequent proliferation have not been explored. Bisectionally cutting primary PLBs resulted in more secondary PLBs at 5 weeks, suggesting an embryogenic stem.. Read More»

Phylogenetic analysis of Elymus (Poaceae) in western China
Authors: H. Song, Z.B. Nan and P. Tian
Elymus L. is often planted in temperate and subtropical regions as forage. Species in the genus have 5 allopolyploid genomes that are found in the grass tribe Triticeae. To determine the phylogenetic relationships in Elymus species from western China, we estimated phylogenetic trees using sequences from the nuclear ribosomal i.. Read More»

Strategies in identifying individuals in a segregant population of common bean and implications of genotype x environment interaction in the success of selection
Authors: M.P. Mendes, M.A.P. Ramalho and A.F.B. Abreu
The objective of this study was to compare the BLUP selection method with different selection strategies in F2:4 and assess the efficiency of this method on the early choice of the best common bean (Phaseolus vulgaris) lines. Fifty-one F2:4 progenies were produced from a cross between the CVIII8511 x RP-26 lines. A randomized .. Read More»

Allelopathy of the invasive plant Bidens frondosa on the seed germination of Geum japonicum var. chinense
Authors: X.F. Wang, D. Hassani, Z.W. Cheng, C.Y. Wang and J. Wu
Five gradient concentrations (0.02, 0.04, 0.06, 0.08, and 0.10 g/mL) of leaching liquors from the roots, stems, and leaves of the invasive plant Bidens frondosa were used as conditioning fluid to examine its influence on seed germination conditions of the native plant Geum japonicum var. chinense in Huangshan. All leaching liquors of organs suppressed the.. Read More»

Genetic diversity and population genetic structure of the miiuy croaker, Miichthys miiuy, in the East China Sea by microsatellite markers
Authors: Y. Qin, D.Q. Sun, T.J. Xu, X.Z. Liu and Y.N. Sun
Genetic diversity and patterns of population structure of the miiuy croaker were investigated using SSR markers. A set of 10 microsatellite loci revealed 40 alleles; the number of alleles varied from 2 to 10 for each marker. A relatively high level of genetic variability was observed between miiuy croaker individuals. Genetic diversity was relatively high.. Read More»

Evaluation of the antimutagenic activity and mode of action of carrageenan fiber in cultured meristematic cells of Allium cepa
Authors: C.I. Nantes1,2, J.R. Pesarini2,3, M.O. Mauro2,4, A.C.D. Monreal1, A.D. Ramires2,3 and R.J. Oliveira2,3,5
In this study, we evaluated the mutagenic and antimutagenic activities of carrageenan, a sulfated polysaccharide, and described its mode of action by using an Allium cepa assay. The results indicate that carrageenan is not mutagenic, rather it has significant chemopreventive potential that is mediated by both demutagenic and bio-antimutagenic activities. .. Read More»

Karyomorphology and karyotype asymmetry in the South American Caesalpinia species (Leguminosae and Caesalpinioideae)
Authors: P.S. Rodrigues, M.M. Souza and R.X. Corr�?ªa
With the purpose of addressing the pattern of karyotype evolution in Caesalpinia species, chromosome morphology was characterized in five species from Brazil, and karyotypic asymmetry was analyzed in 14 species from South America. All accessions had the chromosome number 2n = 24, which was first described here for Caesalpinia laxiflora Tul. and Cenostigma.. Read More»

Genome-wide transcriptional profiling reveals molecular signatures of secondary xylem differentiation in Populus tomentosa..
Authors: X.H. Yang1,2, X.G. Li3, B.L. Li1,2,4 and D.Q. Zhang
Wood formation occurs via cell division, primary cell wall and secondary wall formation, and programmed cell death in the vascular cambium. Transcriptional profiling of secondary xylem differentiation is essential for understanding the molecular mechanisms underlying wood formation. Differential gene expression in secondary xy..
