Human Calmodulin Methyltransferase: Expression, Activity On Calmodulin, And Hsp90 Dependence, Sophia Magen, Roberta Magnani, Sitvanit Haziza, Eli Hershkovitz, Robert Houtz, Franca Cambi, Ruti Parvari

Horticulture Faculty Publications

Deletion of the first exon of calmodulin-lysine N-methyltransferase (CaM KMT, previously C2orf34) has been reported in two multigene deletion syndromes, but additional studies on the gene have not been reported. Here we show that in the cells from 2p21 deletion patients the loss of CaM KMT expression results in accumulation of hypomethylated calmodulin compared to normal controls, suggesting that CaM KMT is essential for calmodulin methylation and there are no compensatory mechanisms for CaM methylation in humans. We have further studied the expression of this gene at the transcript and protein levels. We have identified 2 additional …

Intraspecific Diversity In Sinningia Speciosa (Gesneriaceae: Sinningieae), And Possible Origins Of The Cultivated Florist's Gloxinia, David Zaitlin Nov 2012

Intraspecific Diversity In Sinningia Speciosa (Gesneriaceae: Sinningieae), And Possible Origins Of The Cultivated Florist's Gloxinia, David Zaitlin

Kentucky Tobacco Research and Development Center Faculty Publications

BACKGROUND AND AIMS: The florist's gloxinia is a familiar houseplant in the Gesneriaceae, the botanical family that includes the African violet (Saintpaulia) and other ornamental species. The gloxinia's wild progenitor is Sinningia speciosa (Lodd.) Hiern, a Brazilian endemic. Although it has been cultivated for almost 200 years, little is known about the genetic diversity in S. speciosa, how the wild populations relate to one another or even where the cultivated forms originated. Using available wild collections, preliminary phenetic and phylogenetic investigations were conducted to elucidate the interspecific relationships within S. speciosa and to infer the origins of the cultivars.

Morphological And Genetic Changes Induced By Excess Zn In Roots Of Medicago Truncatula A17 And A Zn Accumulating Mutant, Ricky W. Lewis, Guiliang Tang, David H. Mcnear Nov 2012

Morphological And Genetic Changes Induced By Excess Zn In Roots Of Medicago Truncatula A17 And A Zn Accumulating Mutant, Ricky W. Lewis, Guiliang Tang, David H. Mcnear

Plant and Soil Sciences Faculty Publications

BACKGROUND: Nutrient fluxes associated with legume-rhizobia symbioses are poorly understood and little is known regarding the influence of abiotic stresses on development and maintenance of N-fixing nodules and root system architecture (RSA). We examined effects of Zn on nodule development and structure, root architecture, and expression of nodulation-related miRNAs in Medicago truncatula and the mutant, raz (requires additional Zn).

FINDINGS: Excess Zn increased root and shoot associated Zn in both genotypes, however, raz plants had lower root associated Zn than WT plants. Roots of raz plants exposed to excess Zn had less volume, surface area, and total length compared to …


Plant Polyadenylation Factors: Conservation And Variety In The Polyadenylation Complex In Plants, Arthur G. Hunt, Denghui Xing, Qingshun Q. Li Nov 2012

Plant Polyadenylation Factors: Conservation And Variety In The Polyadenylation Complex In Plants, Arthur G. Hunt, Denghui Xing, Qingshun Q. Li

Plant and Soil Sciences Faculty Publications

BACKGROUND: Polyadenylation, an essential step in eukaryotic gene expression, requires both cis-elements and a plethora of trans-acting polyadenylation factors. The polyadenylation factors are largely conserved across mammals and fungi. The conservation seems also extended to plants based on the analyses of Arabidopsis polyadenylation factors. To extend this observation, we systemically identified the orthologs of yeast and human polyadenylation factors from 10 plant species chosen based on both the availability of their genome sequences and their positions in the evolutionary tree, which render them representatives of different plant lineages.

RESULTS: The evolutionary trajectories revealed several interesting features of plant polyadenylation factors. …

Strategies To Minimize The Effects Of Drought, Gary Bates Oct 2012

Strategies To Minimize The Effects Of Drought, Gary Bates

Kentucky Grazing Conference

As this summer has shown, forage production from cool-season pasture and hay fields across the state can be dramatically affected by drought. Pastures that consist of cool-season grasses like tall fescue and orchardgrass have been severely overgrazed, and many may have lost some significant stand. Even if you have reseeded these fields, the question is how to prevent having the same problem next year. One of the best practices is to develop a forage program that doesn’t rely on cool-season grasses for summer production, but selects forage species that are better able to produce during periods of limited rainfall and …


Grassfed Beef From A Global Perspective, Glen Aiken Oct 2012

Grassfed Beef From A Global Perspective, Glen Aiken

Kentucky Grazing Conference

Beef production and marketing has been shifting over the last few decades in response to unstable cattle markets, higher input costs, and a need to better meet market demands. Advancement of vertical integration of the production and marketing of beef calves through retained ownership from suckling calf to feedyard has certainly enhanced the genetics of the U.S. beef herd and improved the consistency of beef products. Another shift in production has been an increased number of grassfed cattle (grass finished) for marketing either organic or locally grown beef. These niche markets have developed primarily from concerns of urban consumers regarding …


The Cost Of Pasture Versus Hay, Kenneth H. Burdine Oct 2012

The Cost Of Pasture Versus Hay, Kenneth H. Burdine

Kentucky Grazing Conference

Whenever I discuss the economics of grazing, I like to start by thinking about hay production costs. Regardless of which species we are talking about, a livestock producer should know what his / her most expensive feeding days are. In most cases, these will be winter feeding days, and that will generally consist of feeding either purchased or home-grown hay. So, I encourage producers to start by getting a solid feel for what their daily winter feeding costs are. For the purposes of this article, I am going to present some specific estimates for winter feeding costs, and other items, …


Pastures For Horses, Robert Coleman Oct 2012

Pastures For Horses, Robert Coleman

Kentucky Grazing Conference

For horse owners, the use of pasture in the daily management of their horses provides both exercise for the horses, but also is a valuable source of nutrients. Horse feeding programs are based on forage and pasture is an excellent means to supply nutrients. To make effective use of the forage, horse owners need to manage both the horse and the grass.

Novel Endophyte Tall Fescue, Garry D. Lacefield Oct 2012

Novel Endophyte Tall Fescue, Garry D. Lacefield

Kentucky Grazing Conference

“Novel” endophyte is a term used to describe a “good” or “friendly” fungus (endophyte) in tall fescue as opposed to the endophyte that’s present if over eighty-five percent of the tall fescue in the Fescue Belt of the USA. This endophyte is costing beef producers an estimated $1 Billion dollars in losses from animal gains, reproduction and overall performance.

Effects Of Long-Term Cattle Grazing And Woody Plant Encroachment On Soil Microbial Communities At The Santa Rita Experimental Range, Arizona, Cody Burton, Steven Archer, Rebecca L. Mcculley Oct 2012

Effects Of Long-Term Cattle Grazing And Woody Plant Encroachment On Soil Microbial Communities At The Santa Rita Experimental Range, Arizona, Cody Burton, Steven Archer, Rebecca L. Mcculley

Plant and Soil Sciences Presentations

Livestock grazing is considered a key driver of woody plant encroachment in dryland ecosystems worldwide. Woody plant establishment in these systems creates “islands of fertility,” in part by modifying erosional processes such that soil and plant litter are deposited beneath the shrub canopy, creating a nutrient rich soil/litter matrix that supports enhanced soil microbial biomass pools. In this study, we utilized a long-term grazing exclosure (>80 yrs) at the Santa Rita Experimental Range south of Tucson, Arizona and phopsholipid fatty acid analysis to quantify livestock grazing effects on soil microbial communities associated with the complex vegetative mosaic that characterizes …

Discovery Of Novel Dsrna Viral Sequences By In Silico Cloning And Implications For Viral Diversity, Host Range And Evolution, Huiquan Liu, Yanping Fu, Jiatao Xie, Jiasen Cheng, Said A. Ghabrial, Guoqing Li, Xianhong Yi, Daohong Jiang

Plant Pathology Faculty Publications

Genome sequence of viruses can contribute greatly to the study of viral evolution, diversity and the interaction between viruses and hosts. Traditional molecular cloning methods for obtaining RNA viral genomes are time-consuming and often difficult because many viruses occur in extremely low titers. DsRNA viruses in the families, Partitiviridae, Totiviridae, Endornaviridae, Chrysoviridae, and other related unclassified dsRNA viruses are generally associated with symptomless or persistent infections of their hosts. These characteristics indicate that samples or materials derived from eukaryotic organisms used to construct cDNA libraries and EST sequencing might carry these viruses, which were not easily detected by the researchers. …

Reproductive Characteristics Of A Populus Euphratica Population And Prospects For Its Restoration In China, Dechang Cao, Jingwen Li, Zhenying Huang, Carol C. Baskin, Jerry M. Baskin, Peng Hao, Weilei Zhou, Junqing Li

Biology Faculty Publications

Populus euphratica is a dominant tree in riparian ecosystems in arid areas of northwest China, but it fails to regenerate in these systems. This study evaluates causes for the failure of sexual and asexual regeneration of this species in the wild. P. euphratica disperses as many as 85743 seeds/m2 during summer, and the seeds germinate to 92.0% in distilled water and to 60.8% on silt. However, very few seeds (3.6%) can germinate on unflooded soil. The seed-rain season is prolonged by temporal variability in seed dispersal among individuals, which ensures that seedling emergence can occur during favorable conditions (i.e., …

Evolutionary Genomics Of Mycovirus-Related Dsrna Viruses Reveals Cross-Family Horizontal Gene Transfer And Evolution Of Diverse Viral Lineages, Huiquan Liu, Yanping Fu, Jiatao Xie, Jiasen Cheng, Said A. Ghabrial, Guoqing Li, Youliang Peng, Xianhong Yi, Daohong Jiang Jun 2012

Evolutionary Genomics Of Mycovirus-Related Dsrna Viruses Reveals Cross-Family Horizontal Gene Transfer And Evolution Of Diverse Viral Lineages, Huiquan Liu, Yanping Fu, Jiatao Xie, Jiasen Cheng, Said A. Ghabrial, Guoqing Li, Youliang Peng, Xianhong Yi, Daohong Jiang

Plant Pathology Faculty Publications

BACKGROUND: Double-stranded (ds) RNA fungal viruses are typically isometric single-shelled particles that are classified into three families, Totiviridae, Partitiviridae and Chrysoviridae, the members of which possess monopartite, bipartite and quadripartite genomes, respectively. Recent findings revealed that mycovirus-related dsRNA viruses are more diverse than previously recognized. Although an increasing number of viral complete genomic sequences have become available, the evolution of these diverse dsRNA viruses remains to be clarified. This is particularly so since there is little evidence for horizontal gene transfer (HGT) among dsRNA viruses.

RESULTS: In this study, we report the molecular properties of two novel dsRNA mycoviruses that …

Identification Of Late Embryogenesis Abundant (Lea) Protein Putative Interactors Using Phage Display, Rekha Kushwaha, Taylor D. Lloyd, Kim R. Schäfermeyer, Santosh Kumar, A. Bruce Downie May 2012

Identification Of Late Embryogenesis Abundant (Lea) Protein Putative Interactors Using Phage Display, Rekha Kushwaha, Taylor D. Lloyd, Kim R. Schäfermeyer, Santosh Kumar, A. Bruce Downie

Horticulture Faculty Publications

Arabidopsis thaliana seeds without functional SEED MATURATION PROTEIN1 (SMP1), a boiling soluble protein predicted to be of intrinsic disorder, presumed to be a LATE EMBRYOGENESIS ABUNDANT (LEA) family protein based on sequence homology, do not enter secondary dormancy after 3 days at 40 °C. We hypothesized that SMP1 may protect a heat labile protein involved in the promotion of secondary dormancy. Recombinant SMP1 and GmPM28, its soybean (Glycine max), LEA4 homologue, protected the labile GLUCOSE-6-PHOSPHATE DEHYROGENASE enzyme from heat stress, as did a known protectant, Bovine Serum Albumin, whether the LEA protein was in solution or attached to the bottom …
