Corn And Soybean Production With A Winter Rye Cover Crop, John E. Sawyer, Jose L. Pantoja, Daniel W. Barker
John E. Sawyer
Objectives of this project were to study corn nitrogen (N) fertilization requirement and corn/soybean yield response when grown in a rye cover cropping system. Multiple rates of N fertilizer were applied, with measurement of corn yield response to applied N and soybean yield with and without a fall planted winter rye cover crop. The study was conducted at multiple research farms, with the intent for comparison of with and without a cover crop system across varying soil and climatic conditions in Iowa.

Dihydrosterculate In Tobacco Transformed With Bacterial Cyclopropane Fatty Acid Synthase, Katherine Schmid
Dihydrosterculate In Tobacco Transformed With Bacterial Cyclopropane Fatty Acid Synthase, Katherine Schmid
Katherine Schmid
Many gram negative bacteria accumulate cyclopropane fatty acids (CPFAs) in their membranes during stationary phase. In plants, on the other hand, CPFAs are best known as constituents of certain seed oils. CPFAs make up around 40% of Litchi chinensis seed oil [1] and a significant proportion of oils from other Sapindales. In order Malvales, small amounts of CPFA typically accompany cyclopropene fatty acids in seed oils, although up to 5% CPFA has been observed in the polar lipid fraction from Malvaceous roots [2]. Genetic engineering of oilseeds for unusual fatty acid production requires that the introduced fatty acids accumulate in …

Pants [sic] are transformed with a bacterial cyclopropane fatty acid synthase gene to produce lipids containing cyclopropane fatty acids. Using this technology dihydrosterculate is produced in oilseed crops such as rape.
Urbanization—The Bad, The Good, And The Very Good, Rebecca Dolan
Urbanization—The Bad, The Good, And The Very Good, Rebecca Dolan
Rebecca W. Dolan
Great strides have been made in studying effects of urbanization on plant life in recent years. However, much remains to be learned about how the urban environment acts as a filter on flora. There is some evidence that environments in cities are so similar that they all select for the same plants or plants with the same suite of characteristics, resulting in biotic homogenization, but the jury is still out. We do know that some cities harbor a thriving and diverse native flora. Dolan will talk about what cities can do to increase the chances for long-term survival of native …
The Friesner Herbarium (But) Of Butler University, Rebecca Dolan
The Friesner Herbarium (But) Of Butler University, Rebecca Dolan
Rebecca W. Dolan
The Friesner Herbarium (BUT) of Butler University is a collection of over 100,000 specimens built from the personal herbarium of Ray C. Friesner. He and other botanists at Butler amassed one of the largest and most complete collections of Indiana plants. Active exchange from the 1920’s through the 1940’s increased the holdings of plants from other states. Although the collection does not contain many type specimens, it is rich in vouchers from floristic and ecological studies conducted in the first half of the 20th century and published in the scientific journal,Butler University Botanical Studies.
Hypericum Cumulicola Demography In Unoccupied And Occupied Florida Scrub Patches With Different Time-Since-Fire, Pedro Quintana-Ascencio, Rebecca Dolan, Eric Menges
Hypericum Cumulicola Demography In Unoccupied And Occupied Florida Scrub Patches With Different Time-Since-Fire, Pedro Quintana-Ascencio, Rebecca Dolan, Eric Menges
Rebecca W. Dolan
1 Metapopulation models predict that unoccupied, but suitable, patches will exist for species subject to extinction and colonization dynamics. We compared the demographic responses of Hypericum cumulicola, a rare herbaceous species almost entirely restricted to Florida rosemary scrub, when transplanted to occupied or unoccupied patches. 2 Seedlings were transplanted and seeds buried into Florida rosemary scrub patches differing in time since last fire, and in the presence or absence of H. cumulicola. We used a replicated, factorial design to place the transplants and seeds in the field, and monitored their performance for 18 months. 3 Neither time-since-fire nor prior H. …
In Conclusion, Something To Chew On: Native Plant Foods Of The Gold Coast, Simon Grigalius, Daryl Mcphee
In Conclusion, Something To Chew On: Native Plant Foods Of The Gold Coast, Simon Grigalius, Daryl Mcphee
Daryl McPhee
Extract: Ask most people what Gold Coast food is and you may hear answers like the ubiquitous prawn cocktail with avocado, a burger with ' fresh' pineapple available at the local surf club, or fish and chips (eaten on the beach to give it the seaside connection), with the fish often imported from New Zealand or Vietnam. None of this is the true food of the Gold Coast.
The Role Of Protein Kinases Rog1 And Srf6 In The Wak Stress Response Pathway, Jaepil Eric Yoon
The Role Of Protein Kinases Rog1 And Srf6 In The Wak Stress Response Pathway, Jaepil Eric Yoon
Jaepil Eric Yoon
The wall-associated kinases (WAKs) are receptor kinases that bind cell wall pectin to activate expansion and stress response pathways in Arabidopsis thaliana. When bound to pectin polymers, WAKs initiate expansion by inducing the expression of vacuolar invertases that increase cellular turgor pressure, which pushes out against the cell wall. WAKs also bind pathogen or wounding induced pectin fragments called oligogalacturonic acids (OGs). When bound to OGs, WAKs induce a stress response, which leads to the activation of MAP kinases, MPK3 and MPK6. Phosphoproteomics and mass spectrometry identified receptor kinase SRF6, cytoplasmic kinase ROG1, and nuclear DNA binding protein REM2 to …

Genotypic Variation In Lysophospholipids Of Milled Rice, Chuan Tong, Lei Liu, Daniel Le Waters, Terry J. Rose, Jinsong Bao, Graham J. King
Genotypic Variation In Lysophospholipids Of Milled Rice, Chuan Tong, Lei Liu, Daniel Le Waters, Terry J. Rose, Jinsong Bao, Graham J. King
Adjunct Associate Professor Daniel LE Waters
Phospholipids (PLs) play a prominent role in both grain cellular structure and Phospholipids (PLs) play a prominent role in both grain cellular structure and nutritional function of cereal crops. Their lyso forms (lysophospholipids, LPLs) often combine with cereal starch to form an amylose-lipid complex (ALC) which may influence starch properties. In this study, 20 rice accessions were grown over two seasons at the same location to explore diversity in LPLs of milled rice. Levels of specific LPLs differed significantly among rice genotypes, demonstrating there is a wide diversity in LPLs in rice grain. The main LPL components were lysophosphatidylcholine (LPC)16:0 …
Wild Rides And Wildflowers: Philosophy And Botany With Bikes, Scott Abbott, Sam Rushforth
Wild Rides And Wildflowers: Philosophy And Botany With Bikes, Scott Abbott, Sam Rushforth
Scott Abbott
This book bears only passing resemblance to any book we have read to date. We hope it is comical, perhaps in ways that will remind readers of NPR’s “Car Talk,” where listeners share the good natured and sometimes acidic banter between brothers who also know a lot about cars. We hope it is moving, not in the extended ways Terry Tempest Williams often achieves, but through surprising comments and stories that accompany the bike rides and that, over the course of four years, add up to a larger picture. We hope it is informative, not in the comprehensive way John …

Modulation Of Natural Killer Cell Activity By Water Soluble Polysaccharides From The Roots Of Asparagus Racemosus Linn, M Thakur, P Connellan, Myrna Deseo, Carol Morris, V Dixit
Dr Myrna A Deseo
Asparagus racemosus L. (Fam. Liliaceae) is an ethno-pharmacologically acclaimed Ayurvedic medicinal plant [1]. The plant belongs to the category of 'Rasayana' i.e., plants possessing immunomodulatory and adaptogenic activity [2]. Although there have been claims on immune system potentiation by aqueous extracts of A. racemosus, there is a lack of information specifying the exact molecular mechanism and phytochemical components responsible for the immuno-stimulatory activity.
In the present study, an aqueous extract of A. racemosus (ARC) was further fractionated to isolate the polysaccharide fraction (ARP). The isolated polysaccharides (ARP) were characterized by enzymatic, size exclusion, GC-FID, and thin layer chromatographic analyses. …

Chemical Composition And Biological Activity Of The Essential Oils From Native Australian Callitris Species, Angela Oprava, David Leach, Karren Beattie, Paul Connellan, Paul Forster, Greg Leach, Gerhard Buchbauer, Kellie Shepherd, Myrna Deseo
Dr Myrna A Deseo
The chemical composition of the essential oil of the wood of the Australian native cypress Callitris endlicheri, C. intratropica and C. columellaris were determined by GCMS. The colour of the oils from C. endlicheri were yellow, yellow green and light green, whilst the distinct blue colour of the oil from C. intratropica was in keeping with its generic name ‘blue cypress oil'. The sesquiterpene alcohol guaiol (1) comprised >50% of the C. endlicheri oil. Significant differences were observed in components between the three accessions. In contrast, the oils of C. intratropica showed more subtle variations between collection …
