Authors: Y.M. Xie, L. Jin, X.J. Chen, M.N. He, Y. Wang, R. Liu, M.Z. Li and X.W. Li
Mitochondrial DNA (mtDNA) content is dependent on the energy requirements of tissues. To date, no comprehensive study has been conducted to examine mtDNA copy number variations in pigs. In the current study, quantitative polymerase chain reaction was performed to quantify the mtDNA copy number in 15 pig tissue types at 5 growth stages from embryo to adult.. Read More»

Influence of sugars and hormones on the genes involved in sucrose metabolism in maize endosperms
Authors: X.D. Ren, H.M. Liu, Y.H. Liu, Y.F. Hu, J.J. Zhang and Y.B. Huang
Starch is the major storage product in the endosperm of cereals. Its synthesis is closely related to sucrose metabolism. In our previous study, we found that the expression of most of the genes involved in starch synthesis might be regulated by sugars and hormones in the maize endosperm. However, little is known regarding the transcriptional regulation of.. Read More»

Hypoxia-related gene expression in porcine skeletal muscle tissues at different altitude
Authors: J. Zhang, L. Chen, K.R. Long and Z.P. Mu
Hypoxia influences many physiological processes, such as respiration, cardiovascular, neurophysiology, and digestion. Skeletal muscle is an important motor organ, which relies on oxygen of oxidation; however, the study of hypoxia in skeletal muscle is lacking. In order to understand the effect of hypoxia on skeletal muscle, we determined the expression le.. Read More»

Expression and hypoxia adaptation analysis of the EPO gene in different tissues of plateau Tibetan pigs
Authors: B.Z. Deji, P. Shang, W.J. Danzeng, H. Zhang and Y.Z. Qiangba
This study aimed to observe the expression characteristics of the erythropoietin (EPO) gene in different tissues of Tibetan pigs and to explore the adaptation to hypoxic environments. The cDNA in heart, liver, lung, kidney, muscle, brain, and fat of Tibetan pigs was used as the template. Through the number of cycles of the polymerase chain reaction (PCR),.. Read More»

Morphological analysis and muscle-associated gene expression during different muscle growth phases of Megalobrama amblycephala
Authors: K.C. Zhu, D.H. Yu, J.K. Zhao, W.M. Wang and H.L. Wang
Skeletal muscle growth is regulated by both positive and negative factors, such as myogenic regulatory factors (MRFs) and myostatin (MSTN), and involves both hyperplasia and hypertrophy. In the present study, morphological changes during muscle development in Megalobrama amblycephala were characterized and gene expression levels were measured by quantitat.. Read More»

Molecular characterization and functional analysis of a Flowering locus T homolog gene from a Phalaenopsis orchid
Authors: D.M. Li, F.B. LÃ?Â?, G.F. Zhu, Y.B. Sun, H.L. Liu, J.W. Liu and Z. Wang
Warm day and cool night conditions significantly induce reproductive spike formation in Phalaenopsis plants; hence, determining the flowering mechanism regulating the reproductive transition is important. Flowering locus T (FT) plays important roles in flowering induction in several plants. To explore spike i.. Read More»

Branches of NF-�ºb signaling pathway regulate hepatocyte proliferation in rat liver regeneration
Authors: C.F. Chang, W.M. Zhao, J.X. Mei, Y. Zhou, C.Y. Pan, T.T. Xu and C.S. Xu
Previous studies have demonstrated that the nuclear factor κB (NF-κB) pathway is involved in promoting cell proliferation. To further explore the regulatory branches and their sequence in the NF-κB pathway in the promotion of hepatocyte proliferation at the transcriptional level during rat liver regeneration, Rat Genome 230 2.0 array was..

Genetic mapping of Theobroma cacao (Malvaceae) seedlings of the Parinari series, carriers of the lethal gene Luteus-Pa
Authors: B.C. Rehem, A.-A.F. Almeida, R.X. Corr�ªa, A.S. Gesteira, M.M. Yamada and R.R. Valle
The lethal gene ‘Luteus-Pa’ is found in cacao genotypes (Theobroma cacao) of the Parinari (Pa) series, from Peru. Seedlings affected by this gene have yellowing leaves and subsequently die. We mapped this gene based on microsatellite markers and RAPDs, in order to elucidate the inheritance of ‘Luteus-Pa&rsquo.. Read More»

Proteomic and gene expression analyses during bolting-related leaf color change in Brassica rapa
Authors: Y.W. Zhang, M.H. Guo, X.B. Tang, D. Jin and Z.Y. Fang
Bolting and flowering are key processes during the growth and development of Chinese cabbage (Brassica rapa L. ssp pekinensis). Understanding the molecular mechanisms underlying bolting and flowering is of significance for improving production of the vegetable. A leaf-color change from bright green to gray-green has been observed following differentiation.. Read More»

Authors: E. Galeano, A.A.M. Barroso, T.S. Vasconcelos, A. L�³pez-Rubio, A.J.P. Albrecht, R. Victoria Filho and H. Carrer
Weed resistance to herbicides is a natural phenomenon that exerts selection on individuals in a population. In Brazil, glyphosate resistance was recently detected in Digitaria insularis. The objective of this study was to elucidate mechanisms of weed resistance in this plant, including genetic variability, allelism, amino acid substitutions, gene expressi.. Read More»
