Arkansas Corn And Grain Sorghum Performance Tests 2002, D. G. Dombek, D. K. Ahrent, R. D. Bond, I. L. Eldridge

Arkansas Agricultural Experiment Station Research Series

Corn and grain sorghum performance tests are conducted each year in Arkansas by the University of Arkansas Division of Agriculture. The tests provide information to companies marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating recommendations for producers. The 2002 corn performance tests contained 59 entries and were conducted at the Northeast Research and Extension Center (NEREC) at Keiser, the Cotton Branch Station (CBS) near Marianna, the Bell Farming Company (BFC) near Des Arc, the Southeast Research and Extension Center - Rohwer Division (SEREC-RD) near Rohwer, and the John Williams Farm (JWF) in Lafayette County. …

Summaries Of Arkansas Cotton Research In Progress In 2001, Derrick M. Oosterhuis

Arkansas Agricultural Experiment Station Research Series

Cotton yields in Arkansas increased steadily during the eighties, but in recent years there has been a leveling off. Of more significance, however, is that extreme year-to-year variability in yields has occurred in the last decade, which is a major point of concern with cotton producers. It has been suggested that this may be related to extreme weather conditions during the boll development period in July and August. Average maximum temperatures in the 2001 season were a few degrees above normal. Recent research in Arkansas has indicated that elevated night temperatures during boll development may be a major contributory factor …

The Shca Protein Is A Molecular Chaperone That Assists In The Secretion Of The Hoppsya Effector From The Type Iii (Hrp) Protein Secretion System Of Pseudomonas Syringae, Karin V. Van Dijk, Vincent C. Tam, Angela R. Records, Tanja Petnicki-Ocwieja, James R. Alfano

Center for Plant Science Innovation: Faculty Publications

Pseudomonas syringae uses a type III protein secretion system encoded by the Hrp pathogenicity island (Pai) to translocate effector proteins into plant cells. One of these effector proteins is HopPsyA. A small open reading frame (ORF), named shcA, precedes the hopPsyA gene in the Hrp Pai of P. s. syringae 61. The predicted amino acid sequence of shcA shares general characteristics with chaperones used in type III protein secretion systems of animal pathogens. A functionally non-polar deletion of shcA in P. s. syringae 61 resulted in the loss of detectable HopPsyA in supernatant fractions, consistent with ShcA acting as a …

Golden Rice: A Case Study In Intellectual Property Management And International Capacity Building, Stanley P. Kowalski, R. David Kryder

Law Faculty Scholarship

In order for agricultural biotechnology (agri-biotech) to play a larger role in the development of sustainable agricultural systems, intellectual property (IP) rights management must be addressed. These issues are not limited to developing countries. With increased globalization, the management of agri-biotech IP rights affects both developing and industrialized countries. In industrialized countries, for example, IP rights risk management entails protection of inventions via strong patent portfolios. For developing countries, IP rights risk management includes the acquisition of rights requisite for the use of inventions essential to the basic welfare of the population. Strategies are needed to bridge these disparate IP …

Van Dijk, Xiaoyan Tang, Alan Collmer

Center for Plant Science Innovation: Faculty Publications

The ability of Pseudomonas syringae pv. tomato DC3000 to parasitize tomato and Arabidopsis thaliana depends on genes activated by the HrpL alternative sigma factor. To support various functional genomic analyses of DC3000, and specifically, to identify genes involved in pathogenesis, we developed a draft sequence of DC3000 and used an iterative process involving computational and gene expression techniques to identify virulence-implicated genes downstream of HrpLresponsive promoters. Hypersensitive response and pathogenicity (Hrp) promoters are known to control genes encoding the Hrp (type III protein secretion) machinery and a few type III effector proteins in DC3000. This process involved (i) identification of …

Breaking Seed Dormancy In Three Poaceae Species, Heidi Jo Larson

Electronic Theses and Dissertations

Seed dormancy is a major impediment to germination testing in seed testing laboratories. Dormant seeds are alive but do not germinate under conditions favorable for germination of non-dormant seeds of the same species. Dormancy in many p􀊆ant species can be broken using a single ·treatment or a combination of treatments. Treatments commonly used are light or dark, various temperature regimes, prolonged exposure to cold treatments (pre-chilling), and the use of growth hormones or other chemicals. Three Poaceae species, winter wheat (Triticum aestiivum), prairie drop seed V (Sporobolus heterolepis), and prairie cordgrass (Spartina pectinata), were the subject …

Fertigation Of Vegetables In Western Australia, J Burt

Bulletins 4000 -

Fertigation is the technique of using soluble fertilisers to supply essential nutrients to vegetables through sprinkler or trickle irrigation systems, or by means of a boom spray. It is ideally suited to most horticultural areas in Western Australia, especially the sandy soils of the Swan Coastal Plain that have a poor capacity to retain nutrients.

Before and after planting, nutrients are often applied to vegetables on soils of the Swan Coastal Plain by applications of poultry manure* or solid fertilisers. After planting, fertigation is a safe and effective method of applying top-dressings of nutrients to crops, especially after the rows …

Clone Size Of Andropogon Gerardii Vitman (Big Bluestem) At Konza Prairie, Kansas, Kathleen H. Keeler, Charles F. Williams, Linda S. Vescio

School of Biological Sciences: Faculty Publications

Clone size of plants of Andropogon gerardii from Konza Prairie Biological Station, Manhattan, Kansas was estimated from spatial patterns of genetic variation, using proteins detected by starch gel electrophoresis and DNA content (ploidy) measured by flow cytometry. Unique multi-locus protein banding patterns and differences in ploidy were used to exclude plants as members of the same clone. Individual clones averaged about 2 m in diameter and areas of prairie of 100 m² were calculated to contain an average of 31.8 genetic individuals.

In Vitro Mutation Induction By Gamma Irradiation For The Improvement Of A Triploid Banana Pisang Berangan (Aaa), Shadia Aldelgadir Mohamed Rayis

Student Works (2000-2009)

Tissue culture and induced mutation techniques were used to generate variation for the improvement of Pisang Bcrangan cv. 'Intan' (AAA). Best field perform ing banana in vitroplants were multiplied and evaluated for better field performance, which included improved agronomic traits such as earliness in fruiting, short plant stature, high yielding capacity with desirable fruit quality and tolerance to Fusarium wilt. A suitable micropropagation medium for Pisang Berangan was established through modification of MS basic medium, which resulted in significant increase in shoot multiplication. Shoot-tip meristems of Pisang Berangan were then irradiated at 20, 30, 40 and 60 Gy to induce …

Reproductive Biology Of Stylisma Pickeringii (Convolvulaceae), An Endangered Plant Of Illinois Sand Prairies, Brent L. Todd

Masters Theses

The sand prairie is a unique ecosystem in the state of Illinois, being the habitat for many interesting plants and animals not found elsewhere in the state. One such plant is the state-endangered Stylisma pickeringii (Torr. ex M.A. Curtis) Gray var. pattersoni (Fern. & Schub.) Myint (Convolvulaceae), also known as Patterson's bindweed or Patterson's dawn flower. It currently is found in only three Illinois counties—Cass, Henderson, and Mason. Presently, two of the three populations of S. pickeringii are located on private lands. Very little information is known about the reproductive biology of S. pickeringii var. pattersoni. Thus, the purpose of …
