An Overview Of The Gene Regulatory Network Controlling Trichome Development In The Model Plant, Arabidopsis, Sitakanta Pattanaik, Barunava Patra, Sanjay Kumar Singh, Ling Yuan

Kentucky Tobacco Research and Development Center Faculty Publications

Trichomes are specialized epidermal cells located on aerial parts of plants and are associated with a wide array of biological processes. Trichomes protect plants from adverse conditions including UV light and herbivore attack and are also an important source of a number of phytochemicals. The simple unicellular trichomes of Arabidopsis serve as an excellent model to study molecular mechanism of cell differentiation and pattern formation in plants. The emerging picture suggests that the developmental process is controlled by a transcriptional network involving three major groups of transcription factors (TFs): the R2R3 MYB, basic helix-loop-helix (bHLH), and WD40 repeat (WDR) protein. …

Development Of Genetic Ssr Markers In Blumeria Graminis F. Sp. Hordei And Application To Isolates From Australia, Madeline Tucker, C S. Moffat, Simon R. Ellwood, K C. Tan, Kithsiri Jayasena, Richard P. Oliver

Biosecurity Research Articles

The barley powdery mildew pathogen, Blumeria graminis f. sp. hordei (Bgh), exists in numerous haplotypes and displays significant differences in fungicide sensitivity. It causes considerable yield losses throughout the world. Microsatellite SSRs are useful tools to study the population level and biogeographic aspects of intraspecific diversity, but so far none have been defined for Bgh. Here, eight polymorphic microsatellite loci were identified and characterized. Primer pairs amplifying the loci were then applied to 111 isolates of Bgh from Australia. The number of alleles per locus ranged from 4 to 13, and Nei's genetic diversity ranged from 0·25 to 0·76. The …

Psim24 Is A Novel Versatile Gene Expression Vector For Transient Assays As Well As Stable Expression Of Foreign Genes In Plants, Dipak K. Sahoo, Nrisingha Dey, Indu B. Maiti

Kentucky Tobacco Research and Development Center Faculty Publications

We have constructed a small and highly efficient binary Ti vector pSiM24 for plant transformation with maximum efficacy. In the pSiM24 vector, the size of the backbone of the early binary vector pKYLXM24 (GenBank Accession No. HM036220; a derivative of pKYLX71) was reduced from 12.8 kb to 7.1 kb. The binary vector pSiM24 is composed of the following genetic elements: left and right T-DNA borders, a modified full-length transcript promoter (M24) of Mirabilis mosaic virus with duplicated enhancer domains, three multiple cloning sites, a 3'rbcsE9 terminator, replication functions for Escherichia coli (ColE1) and Agrobacterium tumefaciens (pRK2-OriV) and the replicase trfA …

A Systematic Revision Of North American Tolypella A. Braun (Charophyceae, Charophyta), William Perez

Dissertations, Theses, and Capstone Projects

Charophyta comprises the algal classes Mesostigmatophyceae, Chlorokybophyceae, Klebsormidiophyceae, Coleochaetophyceae and Zygnematophyceae and the land plants. However, the precise phylogenetic position of these algal classes with respect to land plants is unresolved as are the phylogenetic relationships among genera in Charophyceae (Characeae). Characeae contains two tribes with six genera: tribe Chareae (Chara, Lamprothamnium, Lychnothamnus and Nitellopsis) and tribe Nitelleae (Nitella and Tolypella). Tolypella was considered the third most species-rich genus but, in the most comprehensive taxonomic treatment of Characeae, 16 Tolypella species were consolidated into two species, T. nidifica and T. intricata in sections Rothia …

USU Student Organic Farm Newsletter

As you know gardens can come with challenges, however being prepared with knowledge and tools can help prevent a challenge from becoming a serious problem. This spring some of our challenges have been pests. It is important to be aware of the their signs and then take the proper active action to apply barriers that prevent problematic pests from causing too much damage.

Patch-Burn Grazing Effects On Cattle Performance: Research Conducted In A Working Landscape, Stephen L. Winter, Samuel D. Fuhlendorf, Mark Goes

School of Natural Resources: Faculty Publications

• Patch-burn grazing is a range management strategy that might be able to simultaneously optimize livestock production objectives and wildlife habitat objectives.

• We compared patch-burn grazing to a traditional range management strategy in multiple pastures, representing a variety of land ownership and management histories, dispersed across a relatively large geographic area. Our results likely represent what land managers could expect if they adopted patch-burn grazing in similar situations.

• We found that cattle performance in pastures managed with patch-burn grazing did not differ from that found in pastures managed with a traditional range management strategy. This suggests that land …

Recent Cropping Frequency, Expansion, And Abandonment In Mato Grosso, Brazil Had Selective Land Characteristics, Stephanie A. Spera, Avery S. Cohn, Leah K. Vanwey, Jack F. Mustard, Bernardo F.T. Rudorff, Marcos Adami

Geography and the Environment Faculty Publications

This letter uses satellite remote sensing to examine patterns of cropland expansion, cropland abandonment, and changing cropping frequency in Mato Grosso, Brazil from 2001 to 2011. During this period, Mato Grosso emerged as a globally important center of agricultural production. In 2001, 3.3 million hectares of mechanized agriculture were cultivated in Mato Grosso, of which 500 000 hectares had two commercial crops per growing season (double cropping). By 2011, Mato Grosso had 5.8 million hectares of mechanized agriculture, of which 2.9 million hectares were double cropped. We found these agricultural changes to be selective with respect to land attributes —significant …

Effect Of Monetary Policy On Agricultural Sector In Nigeria, Elias A. Udeaja, Udoh A. Elijah

Economic and Financial Review

The study examinee the effect of monetary policy on agricultural sector in Nigeria, utilizing time series data for the periods spanning from 1970 to 2010. The study captures both monetary and non-monetary policy variables such as lending rate, commercial banks credit to agriculture, exchange rate, government expenditure in agriculture and inflation rate in examining the effect of monetary policy on agricultural output. The methodology adopted is the Auto- Regressive Distributed Lag (ARDL) Bound Testing Approach. The results obtained shows that exchange rate and government expenditure had positive and significant effect on agricultural output and, hence agricultural sector in Nigeria. It …

Grazing Method Effects On Forage Production, Utilization, And Animal Performance On Nebraska Sandhills Meadow, Miles D. Redden

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Mob grazing using ultrahigh stocking densities is promoted as a tool to increase the health and productivity of grasslands by increasing nutrient cycling and soil organic matter. Mob grazing can be defined as a strategy in which area available to grazing animals is restricted to achieve stocking densities of 200,000 kg/ha or greater. Objectives were to determine herbage production, utilization, and cattle weight gains among ultrahigh stocking density grazing and more conventional grazing methods on a Sandhills subirrigated meadow. Treatments included two replications of each of the following: four-pasture rotational grazing with two occupations per pasture in an 80-day grazing …

Bee Colony Startup And Cost Analysis, Marisela Herrera

BioResource and Agricultural Engineering

The increase in demand for European Honey bee pollination along with colony collapse disorder has caused bee pollination rental fees to greatly increase. This project intended to determine how effective and economically feasible it would be for almond growers to begin raising their own hives for pollination. It was determined the biggest challenges were organizing and finding employees who were knowledgeable about bee keeping. When looking at the cost it was clear that even with the current cost per hive the startup costs were still less than the total rental fees for a single pollination season.

Once the hives have …
