We collected soil samples from 27 study sites across North Central United States to compare the soil carbon of short rotation poplar plantations to adjacent agricultural crops and woodlots. Soil organic carbon (SOC) ranged from 20 to more than 160 Mg/ha across the sampled sites. Lowest SOC levels were found in uplands and highest levels in riparian soils. We attributed differences in bulk density and SOC among cover types to the inclusion of woodlot soils in the analysis. Paired comparison found few differences between poplar and agricultural crops. Sites with significant comparisons varied in magnitude and direction. Relatively greater SOC was often observed in poplar when native soil carbon was low, but there were important exceptions. Woodlots consistently contained greater SOC than the other crops, especially at depth. We observed little difference between paired poplar and switchgrass, both promising bioenergy crops. There was no evidence of changes in poplar SOC relative to adjacent ...
Small RNAs regulate a large set of gene expression in all plants and constitute a natural immunity against viruses. Small RNA based genetic engineering (SRGE) technology had been explored for crop protection against viruses for nearly thirty years. Viral resistance has been developed in diverse crops with SRGE technology and a few viral resistant crops have been approved for commercial release. In this review we summarized the efforts generating viral resistance with SRGE in different crops, analyzed the evolution of the technology, its efficacy in different crops for different viruses and its application status in different crops. The challenge and potential solution for application of SRGE in crop protection are also discussed.

Through advancements in agriculture and the development of new crop varieties, humans have historically strived to meet the needs of a growing population and to develop a safe, reliable and sustainable food supply. How will we continue to meet this challenge, while dealing with a changing climate and threats of new pests and diseases? The American Seed Trade Association (ASTA) affirms that continued innovation is paramount to the future of agriculture and to our shared quality of life. Plant breeders including those who develop new wheat varieties will need access to available tools to responsibly meet these challenges.. The fundamental practices of plant breeders have not changed over time, ASTA notes. Plant breeders still select the best plants for their desired goal, which may be higher yields, disease resistance, improved end use characteristics or better nutrition. However, the tools and information that plant breeders use have evolved, allowing them to take advantage of the growing ...
Crop wild relatives, such as the Critically Endangered Beta patula, a primary wild relative of cultivated beets, are of vital importance for food security and agriculture as they can be used to produce new crop varieties. It is estimated that crop wild relatives contribute more than USD 100 billion worldwide towards increased crop yields. Production of at least one third of the worlds food, including 87 of the 113 leading food crops, depends on pollination carried out by insects, bats and birds. This ecosystem service is worth over USD 200 billion per year. According to the IUCN Red List 16% of Europes endemic butterflies are threatened. Bats, which are also important pollinators, are also at risk with 18% threatened globally. The latest IUCN Red List update shows that four members of the hummingbird family, which is known for its pollination services, are now at greater risk of extinction with the Pink-throated Brilliant (Heliodoxa gularis) listed as Vulnerable. In addition to their important ...

Plant agriculture is poised at a technological turning point. Recent advances in genome engineering make it possible to precisely alter DNA sequences in living cells, providing unprecedented control over a plants genetic material. The new technologies are already being widely adopted in academic and industrial research and it is expected that crops developed using these new technologies will be produced world-wide over the coming years.. These emerging crop breeding technologies offer a range of opportunities but also face regulatory challenges and may require new risk assessment approaches.. The Biotechnology and Biological Sciences Research Council (BBSRC) is working with experts from a variety of backgrounds to develop a position statement on developments in new genetic technologies, their application in crop breeding and implications for risk assessment and regulation. The position statement is expected later this summer.. This briefing enabled journalists to find out about molecular ...

The main objectives of this study are to examine: (1) the growth and pattern in Indias food grain production and (2) the decomposition of the total yield increases into pure yield effect and cropping pattern. The present study is based on secondary data for the last 44 years, i.e, from 1955-56 to 1998-99. The study shows that there is, in fact, some deceleration from Pre-green Revolution Period to the Green Revolution Period, coming substantially from a decline in the growth rate of area in the Post-green Revolution Period/Pre-economic Reform Period and Post-economic Reform Period. The major contribution of output is through yield increase. The first order interaction of yield and cropping pattern was a major factor for the growth of food grain output. Therefore, the future effort should be made to stabilize and expand the area of food grains along with increasing yield level. For this, modern technology of agriculture should be promoted, which consists of pest and disease resistant varieties.
A common plant breeding procedure involves moving valuable traits, such as disease resistance, from wild relatives to crop varieties. To achieve this, breeders cross a wild variety to a crop variety. The result is called a hybrid, and it mixes genes from both parents. Most of the genes from the wild variety, however, are unsuited for agriculture and must be cast away. This is done by repeated crossing to the crop variety, coupled to selection for the trait of interest, a process called backcrossing that often requires as many as 10 years. This constitutes a dramatic bottleneck to developing new varieties. Therefore, shortening the development time is particularly critical in the face of unexpected crop challenges when human sustenance depends on the rapid development of new, improved varieties. This project addresses this need. It aims at developing a method for rapid deployment of useful traits into crops, using potato as the experimental system. The collaboration between University of ...

Principal Scientist, Reproduction Biology, Syngenta. Genome editing using CRISPR-Cas9 works efficiently in plant cells, but delivery of genome editing machinery into the vast majority of crop varieties is not possible using established methods. We co-opted the aberrant reproductive process of haploid induction (HI) to induce edits in nascent seeds of diverse monocot and dicot species. Our method, named "HI-Edit", enables direct genomic modification of commercial crop varieties. HI-edit was tested in field and sweet corn using a native haploid inducer line, and extended to dicots using an engineered CENH3 HI system. We also recovered edited wheat embryos using Cas9 delivered by maize pollen. Our data indicate that a transient hybrid state precedes uniparental chromosome elimination in maize HI. Edited haploid plants lack both the haploid inducer parental DNA and the editing machinery. Therefore, edited plants could be used in trait testing and directly integrated into commercial variety ...

I develop an ecophysiological genomic prediction model for grain-filling of rice. First, a crop model of panicle structure and grain weight is bulit based on the field test with various cropping seasons and cutting off flag leaves. Second, a genomic prediction model is built to predict the parameters of the crop model based on the genome-wide marker genotype. The combination of crop modeling and modeling based on quantitative genetics enables us to predict the phenotype of selection candidates under various environmantal conditions. On the basis of the genomic prediction model, crossbreeding simulation reveals the suitable parents to obtain offsprings that performe well under a certain environment. The present study aims to realize the effective and efficient strategy of plant breeding.. ...
INTRODUCTION The overall concept of plant breeding is defined as the science, art and business of improving plants for human benefit (Bernardo 2002). This approach expressly declares that the breeder should have scientific knowledge, individual skills (art) to select plants and/or progenies, the aptness of a good manager and, above all, a holistic view of agriculture and its interactions with human society. In terms of scientific knowledge, the concept of genes/alleles is of course, primarily essential for plant breeders. However, as will be shown, this concept has been changing over time, due to the accumulation of information about how gene regulation and action occur (Wain et al. 2002, Pearson 2006, Gerstein et al. 2007, Scherrer and Jost 2007a,b, Joaquim and El Hani 2010). These changes became more far-reaching after the publication of studies of the genome of some species (AG Initiative 2000, Qing-Po and Qing-Zhong 2006, Orjuela et al. 2010). It is an open question how the gene concept ...

In agriculture, shattering is the dispersal of a crops seeds upon their becoming ripe. From an agricultural perspective this is generally an undesirable process, and in the history of crop domestication several important advances have involved a mutation in a crop plant that reduced shattering - instead of the seeds being dispersed as soon as they were ripe, the mutant plants retained the seeds for longer, which made harvesting much more effective.. A particularly important mutation that was selected very early in the history of agriculture removed the "brittle rachis" problem from wheat.[1] A ripe head ("ear") of wild-type wheat is easily shattered into dispersal units when touched, or blown by the wind, because during ripening a series of abscission layers forms that divides the rachis into short segments, each attached to a single spikelet (which contains 2-3 grains along with chaff).. A different class of shattering mechanisms involves dehiscence of the mature fruit, which releases the ...
Sensor technology, which benefits from high temporal measuring resolution, real-time data transfer and high spatial resolution of sensor data that shows in-field variations, has the potential to provide added value for crop production. The present paper explores how sensors and sensor networks have been utilised in the crop production process and what their added-value and the main bottlenecks are from the perspective of users. The focus is on sensor based applications and on requirements that users pose for them. Literature and two use cases were reviewed and applications were classified according to the crop production process: sensing of growth conditions, fertilising, irrigation, plant protection, harvesting and fleet control. The potential of sensor technology was widely acknowledged along the crop production chain. Users of the sensors require easy-to-use and reliable applications that are actionable in crop production at reasonable costs. The challenges are to develop sensor technology, data
A sustainable agriculture project, led by Michigan State University Crop and Soil Sciences professor and AgBioResearch scientist David Douches, recently earned a 2011 U.S. Department of Agriculture (USDA) Secretarys Honor Award. The award was received in the category "Helping America promote sustainable agricultural production and biotechnology exports as America works to increase food security.". The honored project (actually three projects in one), the "Barley, Wheat, Potato and Tomato Coordinated Agricultural Projects (CAP)" is comprised of a group of researchers and educators from land-grant universities, government agencies and industry groups working together to identify genetic variations in those crops. Discoveries that can help the plants resist disease, increase crop yield and make more efficient use of nutrients are already helping plant breeders develop more sustainable crop varieties.. "The award is a reflection of the great team of post docs, technical staff and students that work ...
Mixed cropping: It is also called as multiple cropping. This is the practice where two different crops or more are grown simultaneously in the same field. The crops are chosen in such a way that the products and waste material from one crop helps in the growth of the other. This type of cropping leads to improving the fertility of the soil thereby increasing the crop yield. Generally, one crop is of long duration while the other is of short duration. One crop requires more nutrients and water while the other requires lesser nutrients or water. As a result, there is a reduction in the competition between the crops for light, nutrients and water. If one crop fails to grow (due to untimely rain or no rains or shortage of nutrients), then the other crop can cover the risk of this complete failure ...

MERCHAN, HD; LUTZ, EE y MORANT, AE. Production of a double-purpose wheat. Phyton (B. Aires) [online]. 2006, vol.75, pp.41-46. ISSN 1851-5657.. In the mixed systems (beef and grain) of the semiarid Pampa, double purpose wheat use might diminish competition by the soil resource, external inputs into the system and money, which are often associated between winter cereals for grazing and/or grain harvest. In the experimental station of the Asociación de Cooperativas Argentinas in Cabildo (wheat semiarid subregion V S), a trial to evaluate shoot and grain production was conducted. The wheat (Triticum aestivum L.) variety Buck Charrúa, commercially recommended for double purpose use was utilized. Grain production of autumn-sown plots, which were defoliated 0, 1, 2 or 4 times, was compared to that of plots sown in winter only for grain production. Grain yield of the autumn-sown wheat without defoliation (control) was 45% less than that of the crop sown in winter for grain (3208 Kg/ha vs 1755 Kg/ha). ...
Please join a special seminar to be given by Christoph Müller of the Postdam Institute for Climate Impacts Research, entitled Global Gridded Crop Modeling Approaches for Global Trade, Food Security, and Nutrition in a Changing World. The seminar is hosted by AgMIP – the Agricultural Model Intercomparison and Improvement Project, in conjunction with the Center for Climate Systems Research and the NASA Goddard Institute for Space Studies. Global crop modeling is particularly uncertain as models have to operate in data-scarce environments. There are large parts of the world where little is known about actual production systems. Similarly, lack of data for model calibration hampers rigorous model evaluation. Still, global crop model applications are invaluable for understanding future challenges to agriculture, as agricultural production systems are interconnected globally through agricultural trade and climate. I will discuss the motivation, challenges and actual progress in global ...
Indias population is bound to cross 1.6 billion by 2050, which will demand doubling of our food grain production to ensure food security to all our people. There is inevitable need of increasing the food grain production and enhancing the agricultural productivity without degrading the environment. This necessitates focus on development of rain-fed areas, degraded lands, analysis of cropping system, proper monitoring and management of agricultural practices, assessing the impact of droughts and floods and so on.
The advantages of free threshing in wheat led to the selection of the domesticated Q allele which is now present in almost all modern wheat varieties. Q and the pre-domestication allele, q, encode an AP2 transcription factor with the domesticated allele conferring a free threshing character and a subcompact (i.e. partially compact) inflorescence (spike). We demonstrate that mutations in the miR172-binding site of the Q gene are sufficient to increase transcript levels via a reduction in miRNA dependent degradation, consistent with the conclusion that a SNP in the miRNA-binding site of Q relative to q was essential in defining the modern Q allele. We also describe novel gain- and loss-of-function alleles of Q and use these to define new roles for this gene in spike development. Q is required for the suppression of sham ramification and increased Q expression can lead to the formation of ectopic florets and spikelets (specialized inflorescence branches that bear florets and grains) resulting in ...
What are IITA and the other centers of the Consultative Group on International Agricultural Research (CGIAR) doing to mitigate the impacts and adapt to the effects of CC on pests? Historically, CGIAR centers have a broad R4D focus; centers have been developing knowledge (e.g., pest profiles), products (e.g., new crop varieties, biocontrol agents against invasive pests), and technologies (e.g., predictive models, diagnostic tools) that are suitable for diverse agroecologies including the tropics, wet, humid, semiarid, and dry, and to some extent the temperate zones as well. The broad knowledge and experience of centers provide an unprecedented advantage to assess the products and technologies in different agroecologies and weather settings and to determine their resilience and ability to cope in altered climatic situations.. Several programs directly focus on managing pests. For instance, the breeding of crop varieties for resistance to pests and pathogens has always been a focus of the CGIAR. ...

Well-tested computer simulation models of the growth, development, and yield of annual crops are being used for a wide range of purposes, including the prediction of impacts of different management practices and land use systems on food production, farmers profitability, and the environment. Presentation and interpretation of simulation results can be significantly enhanced through the linking of models with software that allows spatial visualization. Many users of crop simulation models, however, are located in institutions in developing countries where resources are particularly limited. Computer software to perform a variety of spatial analyses was written, which can be run on modest hardware without the need for costly third-party software. The software is an integral part of the Decision Support System for Agrotechnology Transfer (DSSAT), a comprehensive crop simulation model and data system, but can also be run in a stand-alone mode. Users can run spatial simulation experiments and then ...

Accurate and efficient in situ measurement methods of leaf area index (LAI) and leaf angle distribution (LAD) are needed to estimate the fluxes of water and energy in agricultural settings. However, available methods: to estimate these two parameters, especially LAD, are limited. In this study, we propose a field measurement method using multi-angular digital images to estimate LAI and LAD simultaneously from the area proportions of: (i) sunlit soil; (ii) sunlit leaves; (iii) shaded soil; and (iv) shaded leaves. A new expression of the fraction of sunlit leaves is developed based on the radiative transfer theory. Coupling the measured and modeled fractions with an optimization scheme, LAI and the LAD parameters are derived from inverting a fractional model of sunlit and shaded leaves and soil. Through four tests using simulated scenes and in situ measurements for row crops, it is determined that our method performs well. The absolute error of LAI estimation is less than 0.1 when LAI is low ...

The global area sown to genetically modified (GM) varieties of leading commercial crops (soybean, maize, canola, and cotton) has expanded over 100-fold over two decades. Thirty countries are producing GM crops and just five countries (United States, Brazil, Argentina, Canada, and India) account for almost 90% of the GM production. Only four crops account for 99% of worldwide GM crop area. Almost 100% of GM crops on the market are genetically engineered with herbicide tolerance (HT), and insect resistance (IR) traits. Approximately 70% of cultivated GM crops are HT, and GM HT crops have been credited with facilitating no-tillage and conservation tillage practices that conserve soil moisture and control soil erosion, and that also support carbon sequestration and reduced greenhouse gas emissions. Crop production and productivity increased significantly during the era of the adoption of GM crops; some of this increase can be attributed to GM technology and the yield protection traits that it has made
Although he did not understand how diversity arises, Darwin understood that we can alter germplasm as needed by preserving and accumulating the variations found in nature. These are the major goals of any germplasm program.. A diverse germplasm is necessary for breeding both established and new crops. Thus, the improvement of new industrial crops is not appreciably different from the enhancement and breeding of more established food, feed, and fiber crops (Thompson 1990a; White et al. 1994). In both, the plant breeder takes the extant germplasm and searches for genetic variability in desired traits. The major differences are that new crops plant breeders often are working with a species that is not as yet domesticated, they are unfamiliar with the species, and are starting with a limited and frequently un-evaluated or exotic germplasm base (Thompson 1990a). In conventional crops the barriers to domestication were overcome thousands of years ago. Yet access to a diverse germplasm is still ...

Bio-insecticides: Market Outlook Most of the worlds population depends on the agricultural production of plants for food. We are unable to survive without this source of food. Strong population growth has led to an increased demand for food. By the middle of the century, the demand for agricultural products will be 50 percent higher on average than in 2013. Insecticides are a type of pesticide that specifically targets insects that harm the agricultural crop. Bio-insecticides are pesticides made from natural materials that are meant to control or kill insects. These bio-insecticides are composed of animals, plants, bacteria, or minerals found in nature. Bio-insecticides are sprayed on the crop as a pest repellant to control insects by attracting them to trap or disrupting their mating patterns. Bio-insecticides are organic formulations which control the insects that feed on the crop. Use of chemical pesticides led to environmental pollution and an increase in human health problems. Crop ...
Farming in America is losing the diversity needed to keep it alive. But Washington, Jefferson and Uncle Everon already knew that.
In one sense, that is still how modern agriculture works. You look to the future and discard the past. A modern rotation includes only corn, soybeans, fertilizer and pesticides. Whatever you may think about genetically modified crops, the switch to those varieties has driven the rush to the two-crop system. Those crops are designed to tolerate the presence of herbicides. The result is that farmland has been inundated with glyphosate, the herbicide genetically modified crops are engineered for.

The very structure of the agricultural system, as it stands now, is designed to return the greatest profit possible, not to the farmers but to the producers of the chemicals they use and the seeds they plant. And because those chemicals depend on fossil energy, the entire system is inherently unsustainable. What farmers used to return to the soil in the form of labor and
This paper suggests a new approach to econometrically estimate parameters of multi-level Constant Elasticity of Transformation (CET) functional forms which are widely used in developing Computable General Equilibrium (CGE) models. An illustrative CET functional form is estimated using the proposed method based on historical data taken from the U.S. economy for the time period of 1996-210 to evaluate the performance of the new method. The proposed estimation process may be used to improve the existing cropland frontier used in GTAP-BIO model. Currently, the cropland frontier in GTAP-BIO model supplies land to different crops using a simple one-level CET function due to the lack of empirically estimated more flexible functional forms. The proposed method provides an opportunity to estimate more flexible multi-level CET functional forms according to available historical data. This will help to change the land supply side of the GTAP-BIO model based on historical observations. Li, Liang; Taheripour, Farzad;

Entomologia Experimentalis et Applicata. V. 114. P. 119-125. Interpretive Summary: There are several major insect pests of wheat and barley crops in the United States, including the Hessian fly, Russian wheat aphid, bird cherry-oat aphid, and rose grass aphid. Farmers in some parts of the United States use resistant varieties developed by plant breeders and entomologists to protect their wheat crops from Hessian fly and Russian wheat aphid attack. When insect-resistant varieties are unavailable, farmers often use insecticides to control insect pests. This paper reports the result of USDA-ARS research to locate new sources of insect pest resistance in plant and microbial genetic resources stored in seed banks of the U.S. National Plant Germplasm System, thereby determining the potential for giving growers ...

Modeling diseases transmitted by food first requires the ability to model food and food production. Certainly livestock or crops can be represented by a Population Model, as can the food itself. The rate at which animals reproduce can be express modeled with existing birth rate and death rate properties. Crop growth rates might be based on climate data plugins. Food itself (meat, barley) can also be represented by a Population Model, using new parameter or representing spoilage or expiration by a death rate. As abstract populations, both food and food sources are continuous variables that be represented as STEM Integration Decorators. However, to support modeling food production it is also necessary to model the transformation of livestock and living agricultural products into food. To support this in the most general way possible STEM provides a new kind of decorators called a Transformation Decorator with the following properties: ...

Food itself (meat, barley) can also be represented by a Population Model, using new parameter or representing spoilage or expiration by a death rate. As abstract populations, both food and food sources are continuous variables that be represented as STEM Integration Decorators. However, to support modeling food production it is also necessary to model the transformation of livestock and living agricultural products into food. To support this in the most general way possible STEM provides a new kind of decorators called a Transformation Decorator with the following properties: ...
In autumn 2017, farmers in Germany sowed winter grain on 5.16 million hectares of land. The Federal Statistical Office (Destatis) reports that the area cultivated with winter grain for the 2018 harvest is 120,900 hectares smaller (-2%) than the relevant area in 2017.. ...

University of Illinois at Urbana-Champaign. Session II: "Vulnerability of Agriculture and Ecosystems to Climate Change," 10:30 a.m.-noon Tuesday, Sept. 19. Presentation title: "More than Taking the Heat". Abstract: The CO2 concentration in the Earths atmosphere, the main driver of global warming, has been rising at an accelerating rate now increasing at an average annual rate of ,2.1 μmol mol-1. Despite global and regional importance few studies have evaluated the interactive effects of elevated CO2 and temperature on crop photosynthetic physiology, agronomic traits or biomass and seed yield - and no previous work has been done to evaluate the impact of elevated CO2 and temperature under open field conditions. That C4 photosynthesis has a warmer temperature optimum than C3 crops has led to prediction that warming will have less impact on crops like maize compared to C3 crops grown within a region. However, recent modeling and time series studies do not fully support this projection. We have ...
NewsWithViews.com. Whenever large agribusiness or their political representatives come up with a new farm strategy to save local farmers, watch out. It seems that more small farmers suffer while agribusiness prospers. The latest proposal is a bill before Iowa legislators that would prevent local jurisdictions from creating identity preservation zones. Using identity preservation (IP), farmers keep crop varieties separate from others to meet purity requirements of their buyers. Iowa farmers, for example, may earn an extra $8.50 � $15.50 per bushel for organic soybeans. Non-GM beans bring in about $0.50 more than GM varieties, and non-GM food grade raise that to $2.00. Several specialty varieties comprise the approximately 5 percent of total US corn acreage that is IP, including an extractable starch corn grown for Japanese breweries by 60 southeast Iowa farmers. While low commodity corn and soybean prices contributed to the 22 percent reduction of Iowa�s mid-size farms between 1997 and 2002, ...

Africas top plant breeders are working to fight malnutrition and poverty across the continent through improving traditional crops.. An article in African Farming explains the work being done by the African Orphan Crops Consortium to map and make public the genomes of 101 indigenous African foods. These orphan crops are so named because they have largely been ignored by science and seed companies as they are not traded internationally like commodities such as rice, corn and wheat.. Despite this, many of these crops "are crucial to African livelihood and nutrition," says the article.. The consortium was launched in 2012 as a collaboration between the University of California Davis, Mars Inc., a wide range of researchers, industry groups and policymakers. Read more…. ...

Citation: Mutschler, M.A., Wintermantel, W.M. 2006. Reducing virus associated crop loss through resistance to insect vectors. Natural Resistance Mechanisms of Plants to Viruses. G. Loebenstein and J.P. Carr (eds.)241-260. Interpretive Summary: Control of pests and diseases is a major challenge to agricultural production. As insect resistant crops are developed, the question arises as to whether effective insect resistance could be a component in an integrated strategy for control of insect transmitted viruses. The viability of this option depends on the virus, vector, and host plant targeted, the interactions of these organisms, the type of pest resistance available, and how the resistance impacts these interactions. Pest resistance mechanisms that require the pest to feed I order to ingest a toxin or induce the control mechanism are unlikely to reduce the transmission of rapidly acquired and/or transmitted viruses. The most effective pest resistance systems and virus/vector/crop combinations ...

Key Points Historic rainfall over the past year has impacted the nitrate form of N applied (really all mobile nutrients) and in many cases may have been moved out of the soil system. To further complicate the issue, sulfur has also shown up to be a potential barrier in area crop fields. Calculating additional nitrogen (N) is important to ensure adequate N for this seasons crop.

Since the introduction of biologicals, the industry has witnessed tremendous advancements with one of the major contributors being the use of increased intelligence and intensity when it comes to strain selection.. Previously, wild strains were commercialized with little emphasis on refinement. At that time, the overall scientific knowledge about these strains and their potential was relatively unknown; however, today we have many more tools at our disposal. This enables a much greater understanding of biologicals and their capacity for improving plant performance as well as some of the potential pitfalls, such as inconsistent performance. Taking this into account, companies have stepped up their selection procedures. Todays products are more consistent and target specific plant performance traits, such as drought resistance or a pathogen resistance.. Several companies market biological products, containing different types of organisms, for agricultural crops. The largest group of biological ...

Recently announced was the expected 2005 arrival of an ethanol fuelled Saab 9-5. Apparently because ethanol is derived from renewable agricultural crops (which are carbon dioxide absorbing), this will equal out any CO2 emissions whilst driving the car.
I have often thought of the potential Jamaica has for meaningful development. This idea has consistently been echoed by various commentaries. Ever since my awareness of current affairs, I have always heard references to Jamaicas potential for tourism, agricultural crops, reggae music, etc. This has led me to think about why we have not been able to realize this "much talked about" potential and why we always seem to be on the brink of a breakthrough but never attaining it. There is no denying that Jamaica is truly blessed with natural resources and a resilient people and could easily be first class in areas of natural competitive advantage ...

Outcrossing, the unintentional breeding of a domestic crop with a related plant, is considered by the USDAs Animal and Plant Health Inspection Service (APHIS) during review of new plant varieties. The agency ensures that herbicide-tolerant or pest-resistant plants do not become plant pests themselves by out-crossing to weedy relatives. Plant breeders take care to release only new varieties with low or negligible risk of transferring genes to weedy relatives. They also assure that methods are available to manage any weeds that might acquire new genes by outcrossing.. Like traditionally bred plants, genetically modified plants cannot transfer traits to unrelated species in nature. For cases in which weedy relatives exist, APHIS assesses the risk and impact of potential gene transfers. If there is high potential for a new plant variety to outcross with a weedy relative and if transfer of the new trait to the weed could be problematic, APHIS has the authority to halt field trials or further ...

Plants have evolved various ways to resist infection or attack by pests, and pests often evolve ways to get around a plants resistance. This back and forth evolutionary battle generally means that a given crop species includes a range of resistant and susceptible types. In the 1960s, plant breeders found wheat plants with resistance to…
