WPTF (680 AM; "NewsRadio 680") is a news and talk radio station serving the Triangle area of Raleigh, Durham, and Chapel Hill, North Carolina.
 The station call letters date back to the former longtime owner of the station, Durham Life Insurance Company, whose motto was "We Protect The Family."
 Durham Life owned the station from 1927-1992.
 Its studios are located on Highwoods Boulevard in Raleigh, and the transmitter tower is in Cary, North Carolina.
 The station is currently owned by Curtis Media Group.
The Enlist Weed Control System is an agricultural system that includes seeds for genetically modified crops that are resistant to Enlist (a broadleaf herbicide with two active agents, 2,4-Dichlorophenoxyacetic acid (2,4-D) and glyphosate) and the Enlist herbicide; spraying the herbicide will kill weeds but not the resulting crop.
 The system was developed by Dow AgroSciences, part of Dow Chemical Company.
 In October 2014 the system was registered for restricted use in Illinois, Indiana, Iowa, Ohio, South Dakota and Wisconsin by the US Environmental Protection Agency.
 In 2013, the system was approved by Canada for the same uses.
DuPont Pioneer, formerly Pioneer Hi-Bred is a large U.S. producer of hybrid seeds for agriculture.
 They are a major producer of genetically modified organisms (GMOs), including genetically modified crops with insect and herbicide resistance.
Pendimethalin is an herbicide of the dinitroaniline class used in premergence and postemergence applications to control annual grasses and certain broadleaf weeds.
 It inhibits cell division and cell elongation.
 Pendimethalin is listed in the K1-group according to the Herbicide Resistance Action Committee (HRAC) classification and is approved in Europe, North America, South America, Africa, Asia and Oceania for different crops including cereals (wheat, barley, rye, triticale), corn, soybeans, rice, potato, legumes, fruits, vegetables, nuts as well as lawns and ornamental plants.
Bayer AG ( or ); ] ) is a German multinational chemical, pharmaceutical and life sciences company.
 It is headquartered in Leverkusen, where its illuminated sign is a landmark.
 Bayer's primary areas of business include human and veterinary pharmaceuticals; consumer healthcare products; agricultural chemicals and biotechnology products; and high value polymers.
 The company is a component of the Euro Stoxx 50 stock market index.
 The company's motto is "science for a better life."
The Sistema Eléctrico de Aysén (SEA) (Spanish for "Electric System of Aysén") is an alternating current power grid serving the Aysén del General Carlos Ibáñez del Campo Region of Chile.
 It is operated by a private company called EDELAYSEN, whose motto is "La Luz del Sur" (Spanish for "The Light of the South").""
SmartStax is a brand of genetically modified seed made through a collaboration between Monsanto Company and Dow Chemical Company.
 It takes advantage of multiple modes of insect protection and herbicide tolerance.
 SmartStax takes advantage of Yieldgard VT Triple (Monsanto), Herculex Xtra (Dow), RoundUp Ready 2 (Monsanto), and Liberty Link (Dow).
 The traits included protect against above-ground insects, below-ground insects, and provide broad herbicide tolerance.
 It is currently available for corn, but cotton, soybean, and specialty crop variations are to be released.
 Previously, the most genes artificially added to a single plant was three, but Smartstax includes eight.
 Smartstax also incorporates Monsanto's Acceleron Seed Treatment System which protects against insects at the earliest stages of development.
 Smartstax is sold under the Genuity (Monsanto) and Mycogen (Dow) brands.
The systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen.
 SAR is analogous to the innate immune system found in animals, and there is evidence that SAR in plants and innate immunity in animals may be evolutionarily conserved.
 Plants use pattern-recognition receptors to recognize conserved microbial signatures.
 This recognition triggers an immune response.
 The first plant receptors of conserved microbial signatures were identified in rice (XA21, 1995) and in Arabidopsis (FLS2, 2000).
 Plants also carry immune receptors that recognize highly variable pathogen effectors.
 These include the NBS-LRR class of proteins.
 SAR is important for plants to resist disease, as well as to recover from disease once formed.
 SAR can be induced by a wide range of pathogens, especially (but not only) those that cause tissue necrosis, and the resistance observed following induction of SAR is effective against a wide range of pathogens, which is why SAR resistance is sometimes called "broad spectrum."
 SAR is associated with the induction of a wide range of genes (so called PR or "pathogenesis-related" genes), and the activation of SAR requires the accumulation of endogenous salicylic acid (SA).
 The pathogen-induced SA signal activates a molecular signal transduction pathway that is identified by a gene called "NIM1", "NPR1" or "SAI1" (three names for the same gene) in the model genetic system "Arabidopsis thaliana".
 SAR has been observed in a wide range of flowering plants, including dicotyledon and monocotyledon species.
 SAR can be activated in corn, however, widely adapted commercial like Benzothiadiazole may not be efficient against "P. sorghi" causing common rust.
The OECD Better Life Index, launched in May 2011 by the Organisation for Economic Co-operation and Development following a decade of work on this issue, is a first attempt to bring together internationally comparable measures of well-being in line with the recommendations of the Commission on the Measurement of Economic Performance and Social Progress also known as the Stiglitz-Sen-Fitoussi Commission.
 The recommendations made by this Commission sought to address concerns that standard macroeconomic statistics like GDP failed to give a true account of people’s current and future well-being.
 The OECD Better Life Initiative includes two main elements: "Your Better Life Index" and "How's Life?"
LibertyLink is a Bayer owned brand of genes for use in agriculture providing tolerance to Liberty herbicide and glufosinate (a.k.a. Liberty or Basta).
 The genes were developed by Bayer CropScience.
 LibertyLink provides an herbicide resistance system that is still effective in the presence of glyphosate resistant weeds.
 The gene which gives resistance to glufosinate is a bar or pat gene which was first isolated from two species of "Streptomyces" bacteria.

Question: Which company whose motto is "science for a better life" owns a brand of genes that provides an herbicide resistance system?
Answer: Bayer
