2009 Wildflower Of The Year: Skunk Cabbage, Symplocarpus Foetidus, W. John Hayden Jan 2009

2009 Wildflower Of The Year: Skunk Cabbage, Symplocarpus Foetidus, W. John Hayden

Biology Faculty Publications

Skunk cabbage is a coarse herbaceous plant. The stem consists of a stout rhizome oriented vertically in the soil. Leaves and flowers arise from the tip of the rhizome which is often not visible, resulting in the appearance of leaves and flowers arising directly from the swampy mires where these plants grow. Flowers appear during the winter, long before the leaves. The flowers are minute, clustered into a ball-like group (spadix) almost entirely enclosed by a fleshy, hood-like, spathe. The spathe ranges from 8 to 15 cm in height, is more or less pear-shaped, widest near the bottom, and tapers …


Skunk Cabbage Flowers: The Heat Is On, W. John Hayden Jan 2009

Skunk Cabbage Flowers: The Heat Is On, W. John Hayden

Biology Faculty Publications

It is a remarkable sight, as striking as it is unexpected: January skunk cabbages emerging from the frozen mires they call home, melting their way through snow and ice. It seems so improbable because in everyday experience plants exist at equilibrium with ambient temperatures. Leave an apple on the front seat of your car in summer, it gets hot; examine your tomato plants on that first frosty morning in autumn, and they are permeated with ice crystals. People, mammals and birds are inherently warm, and pretty much nothing else is. Except, of course, for the exceptions, of which skunk cabbage …


Time And Temperature Requirements For Effective Removal Of High Molecular Weight Rna From Winter Wheat Genomic Dna With Licl, Benjamin Meyerink, Ryan Geraets Jan 2009

Time And Temperature Requirements For Effective Removal Of High Molecular Weight Rna From Winter Wheat Genomic Dna With Licl, Benjamin Meyerink, Ryan Geraets

The Journal of Undergraduate Research

Numerous protocols are available for the isolation of plant genomic DNA. Often times, these protocols utilize a wide variety of solutions. The primary purpose of this project was to examine the use of LiCl for the removal of RNA contaminants within genomic DNA samples and its dependency on incubation time and temperature. Our results indicate that LiCl is sufficient for the removal of high molecular weight RNA contaminants from genomic DNA. In addition, our results illustrate varying incubation times with LiCl yield minimal differences in the recovery of genomic DNA and the removal of RNA contaminants. Alternatively, different incubation temperatures …

Agroecology As A Science, A Movement And A Practice: A Review, A. Wezel, S. Bellon, T. Doré, Charles A. Francis, D. Vallod, C. David Jan 2009

Agroecology As A Science, A Movement And A Practice: A Review, A. Wezel, S. Bellon, T. Doré, Charles A. Francis, D. Vallod, C. David

Department of Agronomy and Horticulture: Faculty Publications

Agroecology involves various approaches to solve actual challenges of agricultural production. Though agroecology initially dealt primarily with crop production and protection aspects, in recent decades new dimensions such as environmental, social, economic, ethical and development issues are becoming relevant. Today, the term ‘agroecology’ means either a scientific discipline, agricultural practice, or political or social movement. Here we study the different meanings of agroecology. For that we analyse the historical development of agroecology. We present examples from USA, Brazil, Germany, and France. We study and discuss the evolution of different meanings agroecology. The use of the term agroecology can be traced …

Detection And Validation Of Single Feature Polymorphisms Using Rna Expression Data From A Rice Genome Array, Sung-Hyun Kim, Prasanna R. Bhat, Xinping Cui, Harkamal Walia, Jin Xu, Steve Wanamaker, Abdelbagi M. Ismail, Clyde Wilson, Timothy J. Close

Department of Agronomy and Horticulture: Faculty Publications

Background: A large number of genetic variations have been identified in rice. Such variations must in many cases control phenotypic differences in abiotic stress tolerance and other traits. A single feature polymorphism (SFP) is an oligonucleotide array-based polymorphism which can be used for identification of SNPs or insertion/deletions (INDELs) for high throughput genotyping and high density mapping. Here we applied SFP markers to a lingering question about the source of salt tolerance in a particular rice recombinant inbred line (RIL) derived from a salt tolerant and salt sensitive parent. Results: Expression data obtained by hybridizing RNA to an oligonucleotide array …

Antibiotic Use In Animal Production: Environmental Concerns, Teshome H. Regassa, Richard K. Koelsch, Charles S. Wortmann, Richard F. Randle, Akwasi A. Abunyewa

Department of Agronomy and Horticulture: Faculty Publications

Introduction

Antibiotic1 use in animal production has led to improved feed use efficiency and increased growth rates. In turn, these resulted in reduced food production costs and reduced excrement of manure nutrients which may cause pollution problems.

On the other hand, antibiotic use leads to antibiotic resistance and a possible reduction in effectiveness of treatment options for both animals and humans. This publication addresses these issues.

Disease-causing microorganisms2, including bacteria,are the most diverse and numerous organisms on earth. Diverse in their habitat, environmental adaptation, and mechanisms of reproduction, they have short generations with high multiplication rates. Such characteristics help develop …
