Genuity Smartstax Corn: an Amazing Advancement in GE Crop
Genuity SmartStax corn: An amazing advancement in GE crop 05 May 2010 | News Image not found or type unknown Using GS corn as a platform would be a quicker way of enhancing the number of transgenes in a single crop variety The trademarked Genuity-SmartStax corn (GS corn) containing eight transgenes-six for pest control and two for weed control- developed through collaboration between Monsanto and Dow AgroSciences, introduced few months ago, is an amazing development in crop genetic engineering (GE). Incorporated into the best of corn varieties, this event is expected to provide the most comprehensive pest and weed control system available, leading to an impressive crop health and increase of whole farm crop yields. The development of Genuity SmartStax corn from the shaky origins of genetic engineering is a fascinating reading. Genuity SmartStax corn GS corn takes care of the major pests, such as the European and southwestern corn borer, northern and western corn rootworm, western bean cutworm, black cutworm, corn earworm, and fall armyworm and also imparts tolerance to both glyphosate and glufosinate herbicides. In addition, the coming together of two giants in the seed industry will encourage other private-private partnerships to further this initiative. Eight transgenes in GS corn Tolerance to aerial pests (three Bt genes): Cry 1A.105 (Monsanto), Cry 2Ab2 (Monsanto) and Cry 1F (Dow). Tolerance to subsoil pests (three Bt genes): Cry 3Bb1 (Monsanto), Cry 34Ab1 (Dow) and Cry 35Ab1 (Dow). Tolerance to herbicides (two genes): Glyphosate (Roundup Ready, Monsanto) and Glufosinate (LibertyLink, Dow, under license from Bayer). Biosecurity evaluation Transgenic crops are evaluated for product efficacy and biosecurity in the laboratory, green house and in the field for over 10 years before commercialization. -

Quick and Efficient Method for Genetic Transformation of Biopolymer
Technical Note Received: 29 July 2009 Revised: 14 September 2009 Accepted: 14 September 2009 Published online in Wiley Interscience: 29 October 2009 (www.interscience.wiley.com) DOI 10.1002/jctb.2284 Quick and efficient method for genetic transformation of biopolymer-producing bacteria Qin Wang,a Alexander P. Mueller,a Chean Ring Leong,b Ken’ichiro Matsumoto,b Seiichi Taguchib and Christopher T. Nomuraa∗ Abstract In order to genetically modify microorganisms capable of producing polyhydroxyalkanoate (PHA) biopolymers, a simple and rapid method to prepare freshly plated Pseudomonas cells for transformation via electroporation was developed. This method can be used to transfer both replicative plasmids and linear DNA to knock out genes into the cells. The transformation efficiencies were in the range of ≥107 transformants µg−1 DNA for replicative plasmids and ≥106 transformants µg−1 DNA for linear DNA, which are comparable with commercially available competent cells. Furthermore, this transformation procedure can be performed in less than 10 min, saving a great deal of time compared with traditional methods. Knockout mutants of several Pseudomonas species were generated by transformation of linear DNA and these mutations were verified by PCR and analysis of PHA content. c 2009 Society of Chemical Industry Keywords: transformation; electroporation; Pseudomonas putida; polyhydroxyalkanoates (PHAs) INTRODUCTION using various strains of P. putida.StrainsweregrowninLuria- Pseudomonas putida is a Gram-negative soil bacterium that plays Bertani (LB) medium (1% tryptone, 0.5% yeast extract, and 0.5% animportantroleinelementcycling innature,bioremediation,and NaCl) with the appropriate antibiotic when necessary.

MIAMI UNIVERSITY The Graduate School Certification for Approving the Dissertation We hereby approve the Dissertation of Stephen Hess Candidate for the Degree: Doctor of Philosophy ____________________________________ Director (Dr. Venelin Ganev) ____________________________________ Reader (Dr. Gulnaz Sharafutdinova) ____________________________________ Reader (Dr. Adeed Dawisha) ____________________________________ Graduate School Representative (Dr. Stanley Toops) ABSTRACT AUTHORITARIAN LANDSCAPES: STATE DECENTRALIZATION, POPULAR MOBILIZATION, AND THE INSTITUTIONAL SOURCES OF RESILIENCE IN NONDEMOCRACIES by Stephen Hess Beginning with the insight that highly-centralized state structures have historically provided a unifying target and fulcrum for the mobilization of contentious nationwide social movements, this dissertation investigates the hypothesis that decentralized state structures in authoritarian regimes impede the development of forms of popular contention sustained and coordinated on a national scale. As defined in this work, in a decentralized state, local officials assume greater discretionary control over public expenditures, authority over the implementation of government policies, and latitude in managing outbreaks of social unrest within their jurisdictions. As a result, they become the direct targets of most protests aimed at the state and the primary mediators of actions directed at third-party, non-state actors. A decentralized state therefore presents not one but a multitude of loci for protests, diminishing claimants‘ ability to use the central state as a unifying target and fulcrum for organizing national contentious movements. For this reason, decentralized autocracies are expected to face more fragmented popular oppositions and exhibit higher levels of durability than their more centralized counterparts. To examine this claim, I conduct four comparative case studies, organized into pairs of autocracies that share a common regime type but vary in terms of state decentralization. -

Biotechnology Benefits for Corn Production
Agronomic SPOTLIGHT Biotechnology Benefits for Corn Production Many corn products have multiple biotech traits that provide insect protection and herbicide tolerance that promote better plant health, stress tolerance, and yield potential. University of Wisconsin field research trials show that genetically modified corn products (GM) have a number of benefits over conventional corn to help manage downside risk under variable yield conditions and protect yield potential. GM products with insect and herbicide tolerance not only protect corn yield potential, they provide other benefits as well. The large productivity gains in corn production made during the GM corn helped overcome the continuous corn rotation yield last several decades have come primarily from advanced plant penalty that conventional corn experienced during the 2000 breeding techniques and improved corn management of the to 2005 comparison period. crop. Research has determined that about 50% of on-farm yield The University of Wisconsin research shows that farmers gains since 1934 can be attributed to improved management 2 planting GM corn products in a corn-on-corn rotation in 2000 practices.
