Across Bacterial Phyla, Distantly-Related Genomes With Similar Genomic Gc Content Have Similar Patterns Of Amino Acid Usage, John Lightfield, Noah R. Fram, Bert Ely

Faculty Publications

The GC content of bacterial genomes ranges from 16% to 75% and wide ranges of genomic GC content are observed within many bacterial phyla, including both Gram negative and Gram positive phyla. Thus, divergent genomic GC content has evolved repeatedly in widely separated bacterial taxa. Since genomic GC content influences codon usage, we examined codon usage patterns and predicted protein amino acid content as a function of genomic GC content within eight different phyla or classes of bacteria. We found that similar patterns of codon usage and protein amino acid content have evolved independently in all eight groups of bacteria. …

Genes Identified By Visible Mutant Phenotypes Show Increased Bias Toward One Of Two Subgenomes Of Maize, James C. Schnable, Michael Freeling

Department of Agronomy and Horticulture: Faculty Publications

Not all genes are created equal. Despite being supported by sequence conservation and expression data, knockout homozygotes of many genes show no visible effects, at least under laboratory conditions. We have identified a set of maize (Zea mays L.) genes which have been the subject of a disproportionate share of publications recorded at MaizeGDB. We manually anchored these ‘‘classical’’ maize genes to gene models in the B73 reference genome, and identified syntenic orthologs in other grass genomes. In addition to proofing the most recent version 2 maize gene models, we show that a subset of these genes, those that …

Dose–Sensitivity, Conserved Non-Coding Sequences, And Duplicate Gene Retention Through Multiple Tetraploidies In The Grasses, James C. Schnable, Brent S. Pedersen, Sabarinath Subramaniam, Michael Freeling

Department of Agronomy and Horticulture: Faculty Publications

Whole genome duplications, or tetraploidies, are an important source of increased gene content. Following whole genome duplication, duplicate copies of many genes are lost from the genome. This loss of genes is biased both in the classes of genes deleted and the subgenome from which they are lost. Many or all classes are genes preferentially retained as duplicate copies are engaged in dose sensitive protein–protein interactions, such that deletion of any one duplicate upsets the status quo of subunit concentrations, and presumably lowers fitness as a result. Transcription factors are also preferentially retained following every whole genome duplications studied. This …

The Effects Of Parental Support, Best Friend Support, And Parental Psychological Control On Loneliness In Latino Adolescents, Denhi Hortensia Chaney

Theses and Dissertations

The current study examined the relationship of parental support, parental psychological control, and best friend support among Latino adolescents and loneliness using self-esteem as a mediating variable. The sample included 839 Hispanic (primarily Mexican) 9th – 12th graders from west Texas area school districts who were given a self-reported survey to assess parental behaviors and adolescent depression. Using structural equation modeling (SEM), findings indicated that neither maternal nor paternal support was found to be significantly related to loneliness in girls. Only maternal support was found to be significantly related to loneliness in boys. On the other hand, neither maternal nor …

Phylogenetic Evaluation Of Series Delimitations In Section Palmata (Acer, Aceroideae, Sapindaceae) Based On Sequences Of Nuclear And Chloroplast Genes, Jianhua Li

Aliso: A Journal of Systematic and Floristic Botany

Acer section Palmata (Japanese maples) is the largest section within the genus; however, series delimitations within section Palmata have not been evaluated in a phylogenetic context. Both maximum parsimony and maximum likelihood analyses of DNA sequence data of nuclear rDNA ITS and chloroplast genes (ndhF, trnL-trnF, and psbA-trnH) from 23 species of Acer section Palmata show that traditional series do not form individual clades. Results from this study support the most recent taxonomic treatment of Acer that does not recognize any series in section Palmata. Nuclear and chloroplast phylogenies are significantly …

Wood Anatomy Of Family Salvadoraceae From The Indian Subcontinent With Special Reference To The Ultrastructure Of The Vessel Wall, Vishakha Saxena, Sangeeta Gupta

Aliso: A Journal of Systematic and Floristic Botany

The present study describes the wood microstructure of Azima tetracantha, Salvadora oleoides, and S. persica, the members of family Salvadoraceae represented in the Indian Subcontinent. An identification key based on wood anatomical features has been developed for the separation of the species. SEM studies revealed the presence of vesturing in intervessel pits of Salvadora.

Sinker Structure Of Phoradendron Californicum (Viscaceae) Confounds Its Presumed Close Relationship To Other Acataphyllous Species, Rudolf Schmid, Clyde L. Calvin, Carol A. Wilson

Aliso: A Journal of Systematic and Floristic Botany

Phoradendron is the largest genus of New World mistletoes, with about 250 species in two subgenera, Boreales and Aequatoriales, corresponding, respectively, to northern acataphyllous and southern cataphyllous groups. The typically acataphyllous P. californicum of western North America is controversial because recent phylogenetic work has nested it in the southern cataphyllous clade. Seedling establishment, stem anatomy, and endophytic system structure of this species were studied. Seedling haustorial holdfasts have gland cavities, structures considered absent in the Viscaceae clade of Santalales. The stem epidermis has a thick cuticle, deeply sunken stomata, and branched multicellular trichomes. The stem has an outer cortex …

Native Grassland Management Guidelines For Nebraska's Wildlife Management Areas, Gerry Steinauer, Kent Pfeiffer, Jarren Kuipers

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

This document is one of a four part series produced by the Nebraska Game and Parks Commission to provide direction to managers of Wildlife Management Areas (WMAs) in Nebraska. Other documents in the series cover management of woodlands, wetlands, and converted habitats.

Prior to EuroAmerican settlement grasslands covered 98% of the Nebraska landscape and supported the majority of the state’s biodiversity. Since settlement, Nebraska’s native grasslands have suffered serious decline. For example, approximately 98% of eastern Nebraska’s tallgrass prairie has been lost to development. In central and western Nebraska grassland losses have been less dramatic though still substantial. Remnant grasslands …

Comprehensive Identification Of Protein Substrates Of The Dot/Icm Type Iv Transporter Of Legionella Pneumophila., Wenhan Zhu, Simran Banga, Yunhao Tan, Cheng Zheng, Robert E. Stephenson, Jonathan Gately, Zhao-Qing Luo

Department of Biological Sciences Faculty Publications

A large number of proteins transferred by the Legionella pneumophila Dot/Icm system have been identified by various strategies. With no exceptions, these strategies are based on one or more characteristics associated with the tested proteins. Given the high level of diversity exhibited by the identified proteins, it is possible that some substrates have been missed in these screenings. In this study, we took a systematic method to survey the L. pneumophilagenome by testing hypothetical orfs larger than 300 base pairs for Dot/Icm-dependent translocation. 798 of the 832 analyzed orfs were successfully fused to the carboxyl end of β-lactamase. The …

Ponderosa Pine Revisited, J. Robert Haller, Nancy J. Vivrette

Aliso: A Journal of Systematic and Floristic Botany

We here recognize a new variety, Pinus ponderosa var. pacifica, in the Pacific portion of the species' distribution and present a new combination for Washoe pine as a variety, Pinus ponderosa var. washoensis. In this treatment, we reject the neotype of Pinus ponderosa selected by Lauria and designate instead the branch collected by David Douglas with mistletoe (Arceuthobium campylopodum) as lectotype for Pinus ponderosa. Table 1 compares the distinguishing characters of the North Plateau (typical) variety, the Pacific variety, and the Washoe variety of Pinus ponderosa with a closely related species, Pinus jeffreyi. Figure …

Nomenclatural Changes For Some Grasses In California. Ii., James P. Smith Jr., J. Travis Columbus

Aliso: A Journal of Systematic and Floristic Botany

Two additional nomenclatural changes are required for Poaceae treatments that will appear in the second edition of The Jepson Manual: Higher Plants of California. They are Elymus x gouldii and Festuca temulenta. The former corrects a violation of the rule in the International Code of Botanical Nomenclature involving the naming of hybrids, and the latter involves a widely occurring non-native grass in California traditionally assigned to Lolium.

Plants Of The Colonet Region, Baja California, Mexico, And A Vegetation Map Of Colonet Mesa, Alan B. Harper, Sula Vanderplank, Mark Dodero, Sergio Mata, Jorge Ochoa

Aliso: A Journal of Systematic and Floristic Botany

The Colonet region is located at the southern end of the California Floristic Province, in an area known to have the highest plant diversity in Baja California. A preliminary list of vouchered specimens is developed for the area, and a vegetation map for Colonet Mesa is presented. The Colonet region has at least 435 vascular plant taxa, of which 383 are native to Baja California, and 52 are endemic or nearly endemic. This list includes five local endemic taxa known only from the Colonet region, 18 taxa on the California Native Plant Society List 1B of taxa that are "rare, …

Distribution And Regional Ecology Of Californian Palm Oases Interpreted From Google Earth Images, Richard A. Minnich, Ernesto Franco-Vizcaíno, Mario Salazar-Ceseña

Aliso: A Journal of Systematic and Floristic Botany

The native fan palms of the Baja California peninsula (Mexico) and neighboring southern California (USA) comprise two species each in Washingtonia and Brahea. While these are among the most familiar ornamental palms in the world, many features of their taxonomy, distribution, and environmental relationships remain unresolved. We utilized Google Earth Digital Globe imagery (and limited surveys by air and land) to develop the first map detailing the geographic distribution of palm populations in the Peninsular Range Province (PRP) and used these data to formulate new hypotheses on their biotic and abiotic relationships. We inventoried 15,216 populations covering an area …
