Contrasting genetic diversity and differentiation of populations of two successional stages in a neotropical pioneer tree (Eremanthus erythropappus, Asteraceae)
Authors: V.L.O. Freitas, J.P. Lemos-Filho and M.B. Lovato
Eremanthus erythropappus, commonly known as “candeia”,is an abundant pioneer tree species, forming dense populations known as “candeial”, but it is also found in forests at middle stages of succession. Trees from forests are bigger and occur in lower density than in the “candeial”. The objec.. Read More»

Bayesian inference to study genetic control of resistance to gray leaf spot in maize
Authors: M. Balestre, R.G. Von Pinho, A.H. Brito
Gray leaf spot (GLS) is a major maize disease in Brazil that significantly affects grain production. We used Bayesian inference to investigate the nature and magnitude of gene effects related to GLS resistance by evaluation of contrasting lines and segregating populations. The experiment was arranged in a randomized block desi.. Read More»

Genetic diversity of Metrodorea nigra (Rutaceae) from a small forest remnant in Brazil assessed with microsatellite markers
Authors: M.C. Guidugli, R. Ferreira-Ramos, A.C.B. de Sousa, F.W. Cidade, T.G. Marconi, M.A. Mestriner, M. Groppo and A.L. Alzate-Marin
Metrodorea nigra (Rutaceae) is an endemic Brazilian tree of great ecological importance, frequently found in the submontane regions of ombrophilous dense and semideciduous forests. This tree is useful for reforesting degraded areas and the wood can be employed in construction. We developed 12 microsatellite markers from a geno.. Read More»

Genetic diversity and population structure of Fenneropenaeus penicillatus determined by mitochondrial DNA analyses
Authors: Y.Y. Cao and Z.B. Li
Fenneropenaeus penicillatus is a widely distributed economically and ecologically important shrimp species, which is endangered in China. Sequence analysis of 16s rRNA and control region (CR) fragments from mitochondrial DNA was conducted to obtain information on genetic diversity and population structure. Individuals from 12 ..

Identifying differences in protein expression levels by spectral counting and feature selection
Authors: P.C. Carvalho, J. Hewel, V.C. Barbosa and J.R. Yates III
Spectral counting is a strategy to quantify relative protein concentrations in pre-digested protein mixtures analyzed by liquid chromatography online with tandem mass spectrometry. In the present study, we used combinations of normalization and statistical (feature selection) methods on spectral counting data to verify whether.. Read More»

Molecular cloning and functional characterization of a glutathione S-transferase involved in both anthocyanin and proanthocyanidin accumulation in Camelina sativa (Brassicaceae)
Authors: Y. Wang, Y. Tang, M. Zhang, F. Cai, J. Qin, Q. Wang, C. Liu, G. Wang, L. Xu, L. Yang, J. Li, Z. Wang and X. Li
Recently, we found that the Arabidopsis TT19 protein, a glutathione S-transferase, has two functional domains that influence both anthocyanin and proanthocyanidin accumulation. To further understand the function of this protein in the other species, we cloned a cDNA encoding a glutathione S-transferase (namely CMGSTF12) from Camelina sativa, an oil crop t.. Read More»

Development of SNP-based dCAPS markers for identifying male sterile gene tms5 in two-line hybrid rice
Authors: F.S. Song, J.L. Ni1, Y.L. Qian, L. Li, D.H. Ni and J.B. Yang
Molecular markers can increase both the efficiency and speed of breeding programs. Functional markers that detect the functional mutations causing phenotypic changes offer a precise method for genetic identification. In this study, we used newly derived cleaved amplified polymorphic sequence markers to detect the functional mu.. Read More»

Cloning of an anthocyanidin synthase gene homolog from blackcurrant (Ribes nigrum L.) and its expression at different fruit stages
Authors: X.-G. Li, J. Wang and Z.-Y. Yu
Anthocyanidin synthase (ANS), a 2-oxoglutarate (2OG) and Fe(II)-dependent oxygenase, catalyzes the penultimate step in anthocyanin biosynthesis, from leucoanthocyanidins to anthocyanidins, the first colored compound in the anthocyanin pathway. In this study, a full-length, 1427-bp long cDNA named RnANS1, which is homologous to the anthocyanidin synthase g.. Read More»

Cytomixis and meiotic abnormalities during microsporogenesis are responsible for male sterility and chromosome variations in Houttuynia cordata
Authors: J.-Z. Guan, J.-J. Wang, Z.-H. Cheng, Y. Liu and Z.-Y. Li
Houttuynia cordata (Saururaceae) is a leaf vegetable and a medicinal herb througout much of Asia. Cytomixis and meiotic abnormalities during microsporogenesis were found in two populations of H. cordata with different ploidy levels (2n = 38, 96). Cytomixis occurred in pollen mother cells during meiosis at high frequencies and .. Read More»

Abnormal male meiosis explains pollen sterility in the polyploid medicinal plant Pinellia ternata (Araceae)
Authors: Y. Liu, R.-K. Hui, R.-N. Deng, J.-J. Wang, M. Wang and Z.-Y. Li
Pinellia ternata is an important traditional Chinese medicinal plant. Its different populations in China have various ploidy levels, based on x = 13, as well as extensive aneuploid series. The microsporogenesis process was observed in specimens from three populations from three regions of Hubei Province; they were characterize.. Read More»
