An Intergenic Region Shared By At4g35985 And At4g35987 In Arabidopsis Thaliana Is A Tissue Specific And Stress Inducible Bidirectional Promoter Analyzed In Transgenic Arabidopsis And Tobacco Plants, Joydeep Banerjee, Dipak K. Sahoo, Nrisingha Dey, Robert Houtz, Indu B. Maiti

Kentucky Tobacco Research and Development Center Faculty Publications

On chromosome 4 in the Arabidopsis genome, two neighboring genes (calmodulin methyl transferase At4g35987 and senescence associated gene At4g35985) are located in a head-to-head divergent orientation sharing a putative bidirectional promoter. This 1258 bp intergenic region contains a number of environmental stress responsive and tissue specific cis-regulatory elements. Transcript analysis of At4g35985 and At4g35987 genes by quantitative real time PCR showed tissue specific and stress inducible expression profiles. We tested the bidirectional promoter-function of the intergenic region shared by the divergent genes At4g35985 and At4g35987 using two reporter genes (GFP and GUS) in both orientations in transient tobacco protoplast and …


Draft Genome Sequence Of Xylella Fastidiosa Subsp. Multiplex Strain Griffin-1 From Quercus Rubra In Georgia, Jianchi Chen, Hong Huang, Chung-Jan Chang, Drake C. Stenger Sep 2013

Draft Genome Sequence Of Xylella Fastidiosa Subsp. Multiplex Strain Griffin-1 From Quercus Rubra In Georgia, Jianchi Chen, Hong Huang, Chung-Jan Chang, Drake C. Stenger

School of Information Faculty Publications

The draft genome sequence of Xylella fastidiosa subsp. multiplex strain Griffin-1, isolated from a red oak tree (Quercus rubra) in Georgia, is reported here. The bacterium has a genome size of 2,387,314 bp, with a G+C content of 51.7%. The Griffin-1 strain genome contains 2,903 predicted open reading frames and 50 RNA genes.


Elk (Cervus Elaphus) Seasonal Habitat Selection In A Heterogeneous Forest Structure, Jesse N. Popp, David N.C. Mcgeachy, Josef Hamr Jul 2013

Elk (Cervus Elaphus) Seasonal Habitat Selection In A Heterogeneous Forest Structure, Jesse N. Popp, David N.C. Mcgeachy, Josef Hamr

Aspen Bibliography

Seasonal habitat selection by the reintroduced Burwash elk population, approximately 30 km south of Sudbury, Ontario, has been analysed in order to assist in the development of future management. Twenty-five adult females were radio-collared and tracked 1–3 times a week for 3 years. The most prominent patterns included selection of intolerant hardwood forests (trembling aspen, white birch, and balsam poplar) during all seasons, while Great Lakes-St. Lawrence pines (white and red pine dominated stands) were used less than expected based on availability for all seasons. The selection patterns are likely associated with seasonal climatic conditions and forage preferences. Because the …


Characterization Of Resistance To The Cry1f Toxin From Bacillus Thuringiensis In Resistant Fall Armyworm, Spodoptera Frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) From Puerto Rico, Ana Maria Velez Apr 2013

Characterization Of Resistance To The Cry1f Toxin From Bacillus Thuringiensis In Resistant Fall Armyworm, Spodoptera Frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) From Puerto Rico, Ana Maria Velez

Department of Entomology: Dissertations, Theses, and Student Research

Transgenic corn expressing Cry1F protein from Bacillus thuringiensis Berliner has been registered for Spodoptera frugiperda control since 2003. Unexpected damage to Cry1F corn was reported in 2006 in Puerto Rico and Cry1F resistance in S. frugiperda was documented. The inheritance of Cry1F resistance was characterized in a S. frugiperda resistant strain from Puerto Rico which displayed >387-fold resistance to Cry1F. Concentration-response bioassays of reciprocal crosses of resistant and susceptible parental populations indicated that resistance is recessive and autosomal. Bioassays of the backcross of the F1 generation crossed with the resistant parental strain suggest that a single locus is responsible …

Aspen Status Report And Recommendation For The Book Cliffs, Paul C. Rogers, Cody M. Mittanck, Ronald J. Ryel Jan 2013

Aspen Status Report And Recommendation For The Book Cliffs, Paul C. Rogers, Cody M. Mittanck, Ronald J. Ryel

Aspen Bibliography

Regionally quaking aspen (Populus tremuloides Michx.) forests are experiencing numerous impediments to resilience. In the West, recent drought, fire suppression, insects, diseases, climate trends, inappropriate management, and ungulate herbivory are impacting these high biodiversity forests. We conducted a landscape assessment of aspen communities in the Book Cliffs region, Vernal Field Office of the Bureau of Land Management, for the purposes of determining landscape-level status of aspen and making recommendations for future management of these forests. The study area consists of 268 distinct aspen polygons totaling approximately 70 ha (174 acres) of aspen forest surrounded by much larger tracts of …


Wolf Creek Ranch Aspen Monitoring Report, Paul C. Rogers, Allison Jones, James Catlin, James Shuler, Arthur Morris, Michael Kuhns Jan 2013

Wolf Creek Ranch Aspen Monitoring Report, Paul C. Rogers, Allison Jones, James Catlin, James Shuler, Arthur Morris, Michael Kuhns

Aspen Bibliography

In the summer of 2012 we undertook a landscape assessment of aspen forest conditions at Wolf Creek Ranch (WCR) near Kamas, Utah. Using a geographic information system (GIS) coverage of predicted aspen coverage, fifty systematically selected field "plots" were located and mapped with aspen stands around WCR. Seven plots were eventually discarded from our survey due to lack of aspen cover. Volunteer field crews, mostly WCR homeowners, collected aspen data documenting tree sizes, height/age groups, diameters, reproduction, mortality, browse levels, and browse animal use levels.
