• University of Caen study no reason for re-evaluation of genetically modified NK603 maize

  The BfR has scientifically assessed the publication by Séralini et al. (2012). The authors’ conclusion that rats fed with genetically modified NK603 maize throughout their life have a shorter lifespan than animals fed with conventional maize is not sufficiently corroborated by experiments. This is t more

• Studies on domesticated maize identify genes that evolved from wild ancestors

  Maize was likely domesticated in Mexico around 10,000 years ago, and since then humans have continued to radically alter the plant's genetic makeup. Two new papers by a consortium of international researchers, including many at Cornell, identify genes that played a role in corn domestication as well more

• Cornell Chronicle: Leaf gene changes increase corn yield

  A study published in Nature Genetics has identified the genes related to leaf angle in corn (maize) - a key trait for planting crops closer together, which has led to an eight-fold increase in yield since the early 1900s. The study, led by researchers from Cornell and the U.S. Department of Agr more

• Chemometric Spectroscopy
  

  Chemometric Spectroscopy is the term used to describe the direct combination of a spectroscopic measurement with a chemometric data evaluation procedure, typically a multivariate statistic method, so providing quick and reliable deduction of the qualitative and quantitative properties of a sample from its spectrum. A multi-linear regression (MLR) or partial least squares (PLS) regression is usually used for the quantitative determination of individual or combined parameters, while substance identification generally relies on techniques such as discriminant or cluster analysis. more

• New: Multiplex Assays with Universal ProbeLibrary and Assay Design for Many More Organisms
  

  Since the availability of sound sequence data, organisms such as maize, rice, yeast, and zebrafish are gaining more and more importance in academic and industrial research, and the need for specific and quantitative real-time PCR assays for these organisms is growing. Instead of spending time on the lengthy development and optimization of SYBR Green I assays, you can now design highly specific probe-based intron-spanning assays for these organisms. more

• Quantification of Zea mays mRNAs by Real-Time PCR Using the Universal ProbeLibrary
  

  The Universal ProbeLibrary (UPL) is a detection system for real-time PCR based on locked nucleic acid (LNA) probes. We tested the efficiency of the UPL for the quantification of maize transcripts on two detection platforms. The results indicate that the UPL is an attractive alternative to assays based on intercalating dyes or conventional probes. more

• ShortStack: Comprehensive annotation and quantification of small RNA genes [BIOINFORMATICS]

  Small RNA sequencing allows genome-wide discovery, categorization, and quantification of genes producing regulatory small RNAs. Many tools have been described for annotation and quantification of microRNA loci (MIRNAs) from small RNA-seq data. However, in many organisms and tissue types, MIRNA gene more

• Physicochemical characteristics and shelf life estimation of maize/soybean extrudates added with bovine haemoglobin

  Summary Maize/soybean (88:12) extrudates fortified with bovine haemoglobin as a source of iron with the addition of iron absorption enhancers were developed. The aims were to evaluate physicochemical characteristics and to predict shelf life by sensory analysis. Extrudates were made using a Brab more

• The Genomic Signature of Crop-Wild Introgression in Maize

  by Matthew B. Hufford, Pesach Lubinksy, Tanja Pyhäjärvi, Michael T. Devengenzo, Norman C. Ellstrand, Jeffrey Ross-Ibarra The evolutionary significance of hybridization and subsequent introgression has long been appreciated, but evaluation of the genome-wide effects of these phenomena has only rec more
