Genetic damage in Mexican and South American sweet corn varieties due to the use of herbicides (Nicosulfuron and Topramezone)
Authors: M.S. Reynoso, C.M. Alvarez, L.L. De la Cruz, J.F.G. Landeros, J.J.G. S�¡nchez, A.R.A. Villalobos
In order to encourage corn production, several herbicides such as nicosulfuron and topramezone are used. Though they offer great advantages, they may affect crop productivity and may even induce DNA damage. This study evaluated genotoxic activity at two nicosulfuron concentrations (40,000 and 80, 000 ppm) and at four topramezone concentrations (1480, 148,.. Read More»

Genetic diversity and population structure of ancient Platycladus orientalis (Cupressaceae) in the Mausoleum of the Yellow Emperor revealed by SSR
Authors: Yao Xu1, Jiantao Zhao, Sheng Zhang, Zhong Zhao
Ancient trees can serve as genetic reservoirs for special genes, and they are of significance in genetic applications dealing with forest fragmentation, climate change and drought. The Mausoleum of the Yellow Emperor in Shaanxi China has the largest number of ancient Platycladus orientalis trees. Here, Simple sequence repeat (SSR) technique was used to st.. Read More»

Comparing KISS1 and GPR54 genes between the two breeds of goats with low and high prolificacy
Authors: Jie Zheng, Sayed Haidar Abbas Raza, Xiang-Dong Zi, Jian-Yuan Lu
There is increasing evidence that kisspeptin, the peptide product of KISS1 gene and its receptor (GPR54), regulate reproductive processes through actions on other organs than hypothalamus. Therefore, the study for the first time, was conducted to investigate the nucleotide sequences and mRNA expression levels of KISS1 and GPR54 genes in pituitary, endomet.. Read More»

Long non-coding RNA-protein interaction: the preliminary step to track their biological functions
Authors: Amr. R. Ghanam, Wafa Ali, Mohnad Abdalla
RNA is not only an intermediate for the flow of genetic information between DNA and protein. The transcription of the entire genomes generates a myriad non-protein coding RNA in addition to protein coding genes. Among these transcripts, lncRNA which is the least well understood and they cannot be considered as merely transcriptional noises. Here, we revie.. Read More»

DNA Extraction from silica gel preserved common bean (Phaseolus vulgaris L.) leaves
Authors: Male. A.S, Kato. F, Mukankusi. C.M
Extraction of high-quality DNA from field specimen requires collection under liquid nitrogen which is not readily available in resource constrained laboratories in low- and middle-income countries (LMICs). A method of extracting DNA from silica gel preserved common bean (Phaseolus vulgaris L.) leaves is presented. Our method which does not involve the use.. Read More»

Selection of resistance sources to common bean anthracnose by field phenotyping and DNA marker-assisted screening
Authors: A.F. Vieira, L.C.S. Almeida, L.A. Rodrigues, J.G.C. Costa, L.C. Melo, H.S. Pereira, D.A. Sanglard and T.L.P.O. Souza
The main goal of this work was to select resistance sources to common bean anthracnose by field phenotyping and DNA marker-assisted screening. Fifty-five common bean genotypes, including differential varieties, characterized resistance sources, elite lines, cultivars and controls, were evaluated in a field inoculation trial an.. Read More»

CD40 rs4810485 T>G polymorphism and susceptibility to ankylosing spondylitis in the Latvian population
Authors: J. Zepa, L. Silami�·ele, I. Bulina, V. Lavrentjevs, I. Trapina, J. Klovins, D. Andersone, A. Lejnieks and L. Nikitina-Zake
Ankylosing spondylitis (AS) is a potentially disabling form of a systemic chronic inflammatory arthritis affecting mainly the axial skeleton, with or without extraspinal manifestations. The genetic basis of AS is partly known. Moreover, many autoimmunityrelated genes have pleiotropic effects. Multiple functional polymorphisms .. Read More»

Genetic structure and diversity of Senefeldera verticillata (Euphorbiaceae) in semideciduous seasonal forest fragments
Authors: A.A.R. Vieira, A.L. Silva J�ºnior, L.C. Souza, F.D. Miranda, M.F.S. Ferreira and M.V.W. Caldeira
Senefeldera verticillata (Euphorbiaceae) is a species that exclusively occurs in the Atlantic Forest; it is used in the restoration and recovery of degraded areas and has therapeutic uses. Due to the scarcity of information on genetic patterns of this species, genetic diversity was characterized by the use of molecular markers.. Read More»
