Latitudinal Variation Of Freeze Tolerance In Intertidal Marine Snails Of The Genus Melampus (Gastropoda: Ellobiidae), A. B. Dennis, S. H. Loomis, M. E. Hellberg Jan 2014

Latitudinal Variation Of Freeze Tolerance In Intertidal Marine Snails Of The Genus Melampus (Gastropoda: Ellobiidae), A. B. Dennis, S. H. Loomis, M. E. Hellberg

Faculty Publications

Low temperatures limit the poleward distribution of many species such that the expansion of geographic range can only be accomplished via evolutionary innovation. We have tested for physiological differences among closely related species to determine whether their poleward latitudinal ranges are limited by tolerance to cold. We measured lower temperature tolerance (LT50) among a group of intertidal pulmonate snails from six congeneric species and nine locales. Differences in tolerance are placed in the context of a molecular phylogeny based on one mitochondrial (cytochrome oxidase subunit I) and two nuclear (histone 3 and a mitochondrial phosphate carrier protein) markers. Temperate species …

The Hoosier Cavefish, A New And Endangered Species (Amblyopsidae, Amblyopsis) From The Caves Of Southern Indiana, Prosanta Chakrabarty, Jacques A. Prejean, Matthew L. Niemiller

Faculty Publications

We describe a new species of amblyopsid cavefish (Percopsiformes: Amblyopsidae) in the genus Amblyopsis from subterranean habitats of southern Indiana, USA. The Hoosier Cavefish, Amblyopsis hoosieri sp. n., is distinguished from A. spelaea, its only congener, based on genetic, geographic, and morphological evidence. Several morphological features distinguish the new species, including a much plumper, Bibendumlike wrinkled body with rounded fins, and the absence of a premature stop codon in the gene rhodopsin. This is the first new cavefish species described from the United States in 40 years and exemplifies how molecular data can alert us to the presence of otherwise …

Metacom: An R Package For The Analysis Of Metacommunity Structure, Tad Dallas Jan 2014

Metacom: An R Package For The Analysis Of Metacommunity Structure, Tad Dallas

Faculty Publications

Metacommunity theory is an extension of metapopulation theory with the goal of understanding how ecological communities vary through space and time. One off-shoot of metacommunity theory deals with understanding how community structure varies along biotic or environmental gradients. The Elements of Metacommunity Structure framework is a three-tiered analysis of metacommunity structure that enables the user to identify metacommunity properties that arise in site-by-species incidence matrices. These properties can then be related to underlying variables that influence species distributions. The EMS framework is now implemented in metacom, an open source R package that allows for the analysis and plotting of metacommunities. …

Copper Binding In Isca Inhibits Iron-Sulphur Cluster Assembly In Escherichia Coli, Guoqiang Tan, Zishuo Cheng, Yilin Pang, Aaron P. Landry, Jianghui Li, Jianxin Lu, Huangen Ding Jan 2014

Copper Binding In Isca Inhibits Iron-Sulphur Cluster Assembly In Escherichia Coli, Guoqiang Tan, Zishuo Cheng, Yilin Pang, Aaron P. Landry, Jianghui Li, Jianxin Lu, Huangen Ding

Faculty Publications

© 2014 John Wiley & Sons Ltd. Among the iron-sulphur cluster assembly proteins encoded by gene cluster iscSUA-hscBA-fdx in Escherichia coli, IscA has a unique and strong iron binding activity and can provide iron for iron-sulphur cluster assembly in proteins in vitro. Deletion of IscA and its paralogue SufA results in an E. coli mutant that fails to assemble [4Fe-4S] clusters in proteins under aerobic conditions, suggesting that IscA has a crucial role for iron-sulphur cluster biogenesis. Here we report that among the iron-sulphur cluster assembly proteins, IscA also has a strong and specific binding activity for Cu(I) in vivo …

The N-Terminal Domain Of Human Dna Helicase Rtel1 Contains A Redox Active Iron-Sulfur Cluster, Aaron P. Landry, Huangen Ding Jan 2014

The N-Terminal Domain Of Human Dna Helicase Rtel1 Contains A Redox Active Iron-Sulfur Cluster, Aaron P. Landry, Huangen Ding

Faculty Publications

© 2014 Aaron P. Landry and Huangen Ding. Human telomere length regulator Rtel1 is a superfamily II DNA helicase and is essential for maintaining proper length of telomeres in chromosomes. Here we report that the N-terminal domain of human Rtel1 (RtelN) expressed in Escherichia coli cells produces a protein that contains a redox active iron-sulfur cluster with the redox midpoint potential of -248 ± 10 mV (pH 8.0). The iron-sulfur cluster in RtelN is sensitive to hydrogen peroxide and nitric oxide, indicating that reactive oxygen/nitrogen species may modulate the DNA helicase activity of Rtel1 via modification of its iron-sulfur cluster. …

While most of computational annotation approaches are sequence-based, threading methods are becoming increasingly attractive because of predicted structural information that could uncover the underlying function. However, threading tools are generally compute-intensive and the number of protein sequences from even small genomes such as prokaryotes is large typically containing many thousands, prohibiting their application as a genome-wide structural systems biology tool. To leverage its utility, we have developed a pipeline for eThread - a meta-threading protein structure modeling tool, that can use computational resources efficiently and effectively. We employ a pilot-based approach that supports seamless data and task-level parallelism and manages …

Ematchsite: Sequence Order-Independent Structure Alignments Of Ligand Binding Pockets In Protein Models, Michal Brylinski Jan 2014

Ematchsite: Sequence Order-Independent Structure Alignments Of Ligand Binding Pockets In Protein Models, Michal Brylinski

Faculty Publications

© 2014 Michal Brylinski. Detecting similarities between ligand binding sites in the absence of global homology between target proteins has been recognized as one of the critical components of modern drug discovery. Local binding site alignments can be constructed using sequence order-independent techniques, however, to achieve a high accuracy, many current algorithms for binding site comparison require high-quality experimental protein structures, preferably in the bound conformational state. This, in turn, complicates proteome scale applications, where only various quality structure models are available for the majority of gene products. To improve the state-of-the-art, we developed eMatchSite, a new method for constructing …

Environmental Influences On Maize-Aspergillus Flavus Interactions And Aflatoxin Production, Jake C. Fountain, Brian T. Scully, Xinzhi Ni, Robert C. Kemerait, Robert D. Lee, Zhi Yuan Chen, Baozhu Guo

Faculty Publications

Since the early 1960s, the fungal pathogen Aspergillus flavus (Link ex Fr.) has been the focus of intensive research due to the production of carcinogenic and highly toxic secondary metabolites collectively known as aflatoxins following pre-harvest colonization of crops. Given this recurrent problem and the occurrence of a severe aflatoxin outbreak in maize (Zea mays L.), particularly in the Southeast U.S. in the 1977 growing season, a significant research effort has been put forth to determine the nature of the interaction occurring between aflatoxin production, A. flavus, environment and its various hosts before harvest. Many studies have investigated this interaction …

Stylet Penetration Behaviors Of Myzus Persicae (Hemiptera: Aphididae) On Four Ipomoea Spp. Infected Or Noninfected With Sweet Potato Potyviruses, E. N. Wosula, J. A. Davis, C. A. Clark

Faculty Publications

Myzus persicae (Sulzer) is an efficient vector of potyviruses in sweet potato, Ipomoea batatas (L.). These potyviruses also infect members of the morning glory family Ipomoea cordatotriloba Dennstedt and Ipomoea hederacea Jacqin commonly found within or around sweet potato fields. Infection of sweet potato with potyviruses increases the intrinsic rate of increase of M. persicae. Thus, from the epidemiological stand point, virus infection can modify vector population dynamics, and therefore increase virus spread. To better understand this, stylet penetration behaviors of M. persicae on virus infected and noninfected sweet potato cvs. 'Beauregard' and 'Evangeline', as well as morning glory plants …

Faculty Publications

Chemosensory proteins (CSPs) play important roles in chemical communication by insects, as they recognize and transport environmental chemical signals to receptors within sensilla. In this study, we identified HoblCSP1 and HoblCSP2 from a cDNA library of Holotrichia oblita antennae, successfully expressed them in E. coli and purified them by Ni ion affinity chromatography. We then measured the ligand-binding specificities of HoblCSP1 and Hobl CSP2 to 50 selected ligands in a competitive binding assay. These results demonstrated that HoblCSP1 and HoblCSP2 have similar ligand-binding spectra. Both proteins displayed the highest affinity for β-ionone, α-ionone and cinnamaldehyde, indicating that they prefer binding …

Faculty Publications

The crucifer flea beetle, Phyllotreta cruciferae (Goeze) (Coleoptera: Chrysomelidae), has recently emerged as a serious pest of canola (Brassica napus L.) in Montana. The adult beetles feed on canola leaves, causing many small holes that stunt growth and reduce yield. In 2013, damage to canola seedlings was high (≈80%) in many parts of Montana, evidence that when flea beetles emerge in large numbers, they can quickly destroy a young canola crop. In the current study, the effectiveness of several biopesticides was evaluated and compared with two insecticides (deltamethrin and bifenthrin) commonly used as foliar sprays as well as seed treatment …

Are Sweetpotato Weevils (Coleoptera: Brentidae) Differentially Attracted To Certain Colors?, Nirupa Gadi, G. V.P. Reddy Jan 2014

Are Sweetpotato Weevils (Coleoptera: Brentidae) Differentially Attracted To Certain Colors?, Nirupa Gadi, G. V.P. Reddy

Faculty Publications

The sweetpotato weevil Cylas formicarius (F.) (Coleoptera: Brentidae) is one of the most serious insects causing damage to sweetpotatoes in the world. Small populations of these insects can cause severe damage to tubers of the crop. Without proper and effective control, weevil populations are likely to cause a huge or complete loss of sweetpotato production in sweetpotato growing areas. Consequently, there is an urgent need for development of an eco-friendly control method for this weevil. Although some control methods are effective, toxic pesticides applications are detrimental and damaging to our environment. Although pheromone traps are currently being used, no effective …

The Psbp Domain Protein 1 Functions In The Assembly Of Lumenal Domains In Photosystem I, Johnna L. Roose, Laurie K. Frankel, Terry M. Bricker

Faculty Publications

Photosystem I (PS I) is a multisubunit membrane protein complex that functions as a light-driven plastocyanin-ferredoxin oxidoreductase. The PsbP domain protein 1 (PPD1; At4g15510) is located in the thylakoid lumen of plant chloroplasts and is essential for photoautotrophy, functioning as a PS I assembly factor. In this work, RNAi was used to suppress PPD1 expression, yielding mutants displaying a range of phenotypes with respect to PS I accumulation and function. These PPD1 RNAi mutants showed a loss of assembled PS I that was correlated with loss of the PPD1 protein. In the most severely affected PPD1 RNAi lines, the accumulated …
