Rnai-Mediated Control Of Aflatoxins In Peanut: Method To Analyze Mycotoxin Production And Transgene Expression In The Peanut/Aspergillus Pathosystem, Renee S. Arias, Phat M. Dang, Victor S. Sobolev

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The Food and Agriculture Organization of the United Nations estimates that 25% of the food crops in the world are contaminated with aflatoxins. That represents 100 million tons of food being destroyed or diverted to non-human consumption each year. Aflatoxins are powerful carcinogens normally accumulated by the fungi Aspergillus flavus and A. parasiticus in cereals, nuts, root crops and other agricultural products. Silencing of five aflatoxin-synthesis genes by RNA interference (RNAi) in peanut plants was used to control aflatoxin accumulation following inoculation with A. flavus. Previously, no method existed to analyze the effectiveness of RNAi in individual peanut transgenic events, …

Department of Agronomy and Horticulture: Faculty Publications

This review addresses key changes in U.S. agricultural extension and future opportunities. Agricultural extension has been a part of the land-grant university (LGU) system for more than 100 years. The Morrill Act of 1862 established the LGU system by authorizing states access to federally controlled land and funding for public institutions offering educational opportunities focusing on agriculture and mechanical arts for farmers and the working class. Current surveys in Iowa reveal changing trends in extension: more than 90% of farmers identified private-sector crop advisers as their primary source for recommendations, whereas more than 80% of those advisors identified Iowa State …

Rna-Sequencing Reveals Global Transcriptomic Changes In Nicotiana Tabacum Responding To Topping And Treatment Of Axillary-Shoot Control Chemicals, Sanjay Kumar Singh, Yongmei Wu, Jayadri S. Ghosh, Sitakanta Pattanaik, Colin Fisher, Ying Wang, Darlene Lawson, Ling Yuan

Kentucky Tobacco Research and Development Center Faculty Publications

Removal of terminal buds (topping) and control of the formation of axillary shoots (suckers) are common agronomic practices that significantly impact the yield and quality of various crop plants. Application of chemicals (suckercides) to plants following topping is an effective method for sucker control. However, our current knowledge of the influence of topping, and subsequent suckercide applications, to gene expression is limited. We analyzed the differential gene expression using RNA-sequencing in tobacco (Nicotiana tabacum) that are topped, or treated after topping by two different suckercides, the contact-localized-systemic, Flupro^® (FP), and contact, Off-Shoot-T^®. Among the differentially …

Soil Moisture Affects Growing-Season Wildfire Size In The Southern Great Plains, Erik S. Krueger, Tyson E. Ochsner, David M. Engle, J. D. Carlson, Dirac L. Twidwell, Samuel D. Fuhlendorf

Department of Agronomy and Horticulture: Faculty Publications

The increasing availability of soil moisture data presents an opportunity for its use in wildfire danger assessments, but research regarding the influence of soil moisture on wildfires is scarce. Our objective was to identify relationships between soil moisture and wildfire size for Oklahoma wildfires during the growing (May-October) and dormant seasons (November-April). We hypothesized that soil moisture influences wildfire size when vegetation is growing but is less important when most vegetation is dead or dormant. Soil moisture, as fraction of available water capacity (FAW), and commonly measured weather variables were determined for 38,419 wildfires from 2000–2012. Wildfires were grouped by …

Managing Net Income Risk With Crop Insurance, Farm Bill, And Hedging, Cory Walters

Cornhusker Economics

Managing uncertain yields and prices before planting is a primary concern to producers, especially when financial ruin is at stake. To manage uncertainty, producers are presented with a complex set of financial tools from both public sources (crop insurance and Farm Bill) and private sources (commodity futures markets). Over time these tools and their relation have evolved. Prior to the mid-1990s, before crop insurance expanded, producers relied primarily on privately operated commodity futures markets and publicly funded government programs, such as the disaster assistance program and the loan deficiency program, to reduce income uncertainty. Since this time the U.S. government …

Distinguishing Softwoods From Hardwoods, Terry Conners

Agriculture and Natural Resources Publications

Softwood and hardwood trees are made up of different types of cells. With just a little magnification, it’s easy to see that softwood growth rings look different from hardwood growth rings. Additionally, growth rings don’t look the same for all of the trees, and the growth ring appearance is one of the things we will look at to identify wood.

Characteristics Of Kentucky’S Nursery And Greenhouse Industries [2015], Dewayne L. Ingram, Winston Dunwell, Alan Hodges

Agriculture and Natural Resources Publications

The nursery and greenhouse industry in Kentucky is diverse and contributes significantly to the local and state economy. This industry represents the largest segment of Kentucky’s sales of horticultural products and is comprised almost completely of farm families. Nursery and greenhouse operations have historically been characterized as separate production systems and crops. However, today primary nurseries may also have greenhouses and/or produce herbaceous perennials and annuals to satisfy their customer base. On the other hand, many primary greenhouse firms that once grew mostly annuals and potted flowering crops have expanded their product line to include herbaceous perennials, often finished in …

Introduction To Wood Structure And Characteristics, Terry Conners

Agriculture and Natural Resources Publications

Wood is identified using the features and tools that are appropriate to the size of the sample. Large timbers are identified by looking at the color, the appearance of the end and side grain, whether a saw cuts cleanly or leaves lots of splinters behind, whether the wood has straight or curly drying cracks, and so forth. The hardness and density provide valuable information as well. For smaller pieces of wood, it’s more practical to look directly at the wood cells with a 10X hand lens (also called a loupe). Different species have different characteristics and combinations of these features …

Grain Patterns And Growth Rings, Terry Conners

Agriculture and Natural Resources Publications

The preceding article, "Identifying Wood–A Primer for Everyone, Part 3: Distinguishing Softwoods from Hardwoods" (FOR-125), described how to distinguish softwoods from hardwoods, and that’s the first step in identifying an unknown piece of wood. At this point, additional terminology is necessary to further distinguish between species, and I'll begin by talking about the different sides of a hypothetical piece of wood. Frequently you need to be able to observe wood cells from a particular perspective, and you will need to know where to look for different features on your sample. It’s also very helpful to develop a kind of “visual …

The First Separation Of Softwood Species, Terry Conners
