Expression analysis of dihydroflavonol 4-reductase genes in Petunia hybrida
Authors: Y.X. Chu, H.R. Chen, A.Z. Wu, R. Cai and J.S. Pan
Dihydroflavonol 4-reductase (DFR) genes from Rosa chinensis (Asn type) and Calibrachoa hybrida (Asp type), driven by a CaMV 35S promoter, were integrated into the petunia (Petunia hybrida) cultivar 9702. Exogenous DFR gene expression characteristics were similar to flower-color changes, and effects on anthocyanin concentration were observed in both types .. Read More»

Assessment of genetic diversity and variation of Robinia pseudoacacia seeds induced by short-term spaceflight based on two molecular marker systems and morphological traits
Authors: C.Q. Yuan Y.F. Li P. Sun Y.H. Sun G.J. Zhang M.S. Yang Y.Y. Zhang Y. Li L. Wang
The black locust (Robinia pseudoacacia) is a forest legume that is highly valued as a honey plant and for its wood. We explored the effect of short-term spaceflight on development of R. pseudoacacia seedlings derived from seeds that endured a 15-day flight; the genetic diversity and variation of plants sampled from space-mutagenized seeds were compared to pl..

Marker-assisted selection in breeding silkworm strains with high tolerance to fluoride, scaleless wings, and high silk production
Authors: M.W. Li, H.J. Yu, X.L. Yi, J. Li, F.Y. Dai and C.X. Hou
In the silkworm (Bombyx mori), tolerance to fluoride and scaleless wings are controlled by the dominant gene Dtf (dominant tolerance to fluoride) and recessive gene nlw (no Lepidoptera wings), respectively, and these genes have been mapped by using simple sequence repeat and sequence tag site markers. Marker-assisted evaluation and selection of silkworms .. Read More»

PI3K-Akt-mTOR signal inhibition affects expression of genes related to endoplasmic reticulum stress
Authors: Q. Song, C.C. Han, X.P. Xiong, F. He, W. Gan, S.H. Wei, H.H. Liu, L. Li and H.Y. Xu
PI3K-Akt-mTOR signaling pathway is associated with endoplasmic reticulum (ER) stress. However, it is not clear how this signaling pathway affects the ER stress. The present study aimed to determine whether the PI3K-Akt-mTOR signaling pathway regulates tunicamycin (TM)-induced increases in mRNA levels of genes involved in the ER stress, to help elucidate t..

Aggressiveness of Pseudocercospora griseola strains in common bean genotypes and implications for genetic improvement
Authors: R. Pereira, E.A. Souza, Q.L. Barcelos, A.F.B. Abreu and S.S. Librelon
The fungus Pseudocercospora griseola, the causal agent of angular leaf spot in the common bean (Phaseolus vulgaris L.), exhibits a broad pathogenic variability that complicates the development of resistant cultivars. For breeding programs to successfully obtain common bean cultivars with durable resistance, knowing the aggressiveness of different strains,.. Read More»

Acetobacter bacteria are found in Zhenjiang vinegar grains
Authors: C.Y. Wang, J. Zhang and Z.Z. Gui
Zhenjiang vinegar, the grains of which contain a unique microbial flora, is one of the four famous traditional Chinese vinegars. We investigated the components of Zhenjiang vinegar grains. Unique acetic acid bacteria were randomly isolated from Zhenjiang vinegar grains, and the obtained strains were qualitatively analyzed to compare their capacities for a.. Read More»

Ã?Â?6-fatty acid desaturase and fatty acid elongase mRNA expression, phagocytic activity and weight-to-length relationships in channel catfish (Ictalurus punctatus) fed alternative diets with soy oil and a probiotic
Authors: A. Santerre, M.C. TÃ?©llez-BaÃ?±uelos, J. Casas-SolÃ?Âs, P. Castro-FÃ?©lix, M.R. HuÃ?Âzar-LÃ?³pez, G.P. Zaitseva, J.L. Horta-FernÃ?¡ndez, E.A. Trujillo-GarcÃ?Âa, D. de la Mora-Sherer, J.A. Palafox-Luna and E. JuÃ?¡rez-Carrillo
A time-course feeding trial was conducted for 120 days on juvenile channel catfish (Ictalurus punctatus) to study the effects of diets differing in oil source (fish oil or soy oil) and supplementation with a commercial probiotic. Relative levels of Δ6-fatty acid desaturase (Δ6-FAD) and fatty acid elongase (FAE) expression were assessed in brai.. Read More»

Isolation and characterization of novelEST-SSRs in the showy dendrobium, Dendrobium nobile (Orchidaceae)
Authors: J.J. Lu, J.Y. Kang, S.R. Ye and H.Z. Wang
Expressed sequence tag (EST)-derived simple sequence repeat (SSR) markers could enrich the current resource of molecular markers. In this study, microsatellite markers were developed for Dendrobium nobile Lindl. by mining the ESTs. Twenty-eight EST-SSRs amplified 2 to 6 nucleotide repeats with a mean number of 2.82 alleles per.. Read More»
