• Self-powered herbicide biosensor

  A self-powered biosensor that can detect herbicides in water has been developed by US scientists. Most commercial herbicides act by inhibiting photosynthesis in plants. Unfortunately, photosynthetic aquatic microorganisms and aquatic plants are also similarly affected, which is why herbicides are a more

• University of Illinois to improve crop yield through photosynthesis in a new global effort

  The University of Illinois at Urbana-Champaign has received a five–year, $25-million grant from the Bill & Melinda Gates Foundation to improve the photosynthetic properties of key food crops, including rice and cassava. The project, titled "RIPE – Realizing Increased Photosynthetic Efficiency," has more

• Individual protein complex generates electric current
  

  An team of scientists, led by Joachim Reichert, Johannes Barth, and Alexander Holleitner (Technische Universitaet Muenchen, Clusters of Excellence MAP and NIM), and Itai Carmeli (Tel Aviv University) developed a method to measure photocurrents of a single functionalized photosynthetic protein system 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

• Characterizing Environments: Recent Discoveries Enabled by Metagenomic Analysis with the Genome Sequencer FLX System

  Metagenomics is the study of genomic content in a complex mixture of microorganisms. The two primary goals of this approach are to characterize the organisms present in a sample and identify what roles each organism has within a specific environment. Metagenomics samples are found nearly everywhere, including several microenvironments within the human body, soil samples, extreme environments such as deep mines, and the various layers within the ocean. Until recently, technical and economic constraints limited the depth of analysis necessary to obtain a representative picture of microbial and viral communities, their metabolic profiles, and their adaptation dynamics. Advancements in sequencing technologies, including the introduction of massively parallel pyrosequencing with the Genome Sequencer FLX System, have enabled a tremendous groundswell of research in the field of metagenomics. Dramatic improvements in throughput and the elimination of biased cloning steps have extended the field far beyond tradition more

• Overexpression of a MADS-Box Gene from Birch (Betula platyphylla) Promotes Flowering and Enhances Chloroplast Development in Transgenic Tobacco

  by Guan-Zheng Qu, Tangchun Zheng, Guifeng Liu, Wenjie Wang, Lina Zang, Huanzhen Liu, Chuanping Yang In this study, a MADS-box gene (BpMADS), which is an ortholog of AP1 from Arabidopsis, was isolated from birch (Betula platyphylla). Transgenic Arabidopsis containing a BpMADS promoter::GUS constru more

• Photosynthetic and anatomical responses of Eucalyptus grandis leaves to potassium and sodium supply in a field experiment

  Abstract Although vast areas in tropical regions have weathered soils with low potassium (K) levels, little is known about the effects of K supply on the photosynthetic physiology of trees. This study assessed the effects of K and sodium (Na) supply on the diffusional and biochemical limitations more

• Biochemical and quantitative proteomics investigations in Arabidopsis ggt1 mutant leaves reveal a role for the gamma‐glutamyl cycle in plant's adaptation to environment

  The existence of a gamma‐glutamyl cycle consisting of intracellular GSH synthesis, extrusion to the apoplastic space and recovery by gamma‐glutamyl transferase (GGT)‐assisted degradation into its constituent amino acids, has been demonstrated in plants. To address the significance of this cycle in more
