A Survey Of The Vascular Flora Of Beaufort County, South Carolina, Daniel Payne

All Theses

Beaufort County has historically been one of the most poorly botanized counties in the state. Geographically, it lies farther from the major research institutions than most other counties and has therefore received little attention from modern botanists. Major waterways, numerous private communities and an oppressive summer climate further complicate botanical research. Beaufort has one of the fastest growing human populations in the state. Natural areas are rapidly being converted into residential and commercial developments. An understanding of the county's flora is necessary to focus conservation efforts to preserve critical habitat and develop management plans for maintaining biodiversity. This project was …

An Integrative Approach To Genomic Introgression Mapping, Andrew J. Severin, Gregory A. Peiffer, Wayne W. Xu, D. L. Hyten, Bruna Bucciarelli, Jamie A. O'Rourke, Yung-Tsi Bolon, David Grant, Andrew Farmer, Gregory D. May, Carroll P. Vance, Randy C. Shoemaker, Robert M. Stupar

Near-isogenic lines (NILs) are valuable genetic resources for many crop species, including soybean (Glycine max). The development of new molecular platforms promises to accelerate the mapping of genetic introgressions in these materials. Here, we compare some existing and emerging methodologies for genetic introgression mapping: single-feature polymorphism analysis, Illumina GoldenGate single nucleotide polymorphism (SNP) genotyping, and de novo SNP discovery via RNA-Seq analysis of next-generation sequence data. We used these methods to map the introgressed regions in an iron-inefficient soybean NIL and found that the three mapping approaches are complementary when utilized in combination. The comparative RNA-Seq approach offers …

Soydb: A Knowledge Database Of Soybean Transcription Factors, Zheng Wang, Marc Libault, Trupti Joshi, Babu Valliyodan, Henry T. Nguyen, Dong Xu, Gary Stacey, Jianlin Cheng

Department of Agronomy and Horticulture: Faculty Publications

Background: Transcription factors play the crucial rule of regulating gene expression and influence almost all biological processes. Systematically identifying and annotating transcription factors can greatly aid further understanding their functions and mechanisms. In this article, we present SoyDB, a user friendly database containing comprehensive knowledge of soybean transcription factors.

Description: The soybean genome was recently sequenced by the Department of Energy-Joint Genome Institute (DOE-JGI) and is publicly available. Mining of this sequence identified 5,671 soybean genes as putative transcription factors. These genes were comprehensively annotated as an aid to the soybean research community. We developed SoyDB - a knowledge database …

Transgenic Maize Lines With Cell-Type Specific Expression Of Fluorescent Proteins In Plastids, Amir Sattarzadeh, Jonathan Fuller, Salvador Moguel, Katia Wostrikoff, Shirley Sato, Sarah Covshoff, Tom Clemente, Maureen Hanson, David Stern

Department of Agronomy and Horticulture: Faculty Publications

Plastid number and morphology vary dramatically between cell types and at different developmental stages. Furthermore, in C4 plants such as maize, chloroplast ultrastructure and biochemical functions are specialized in mesophyll and bundle sheath cells, which differentiate acropetally from the proplastid form in the leaf base. To develop visible markers for maize plastids, we have created a series of stable transgenics expressing fluorescent proteins fused to either the maize ubiquitin promoter, the mesophyll-specific phosphoenolpyruvate carboxylase (PepC) promoter, or the bundle sheath-specific Rubisco small subunit 1 (RbcS) promoter. Multiple independent events were examined and revealed that maize codon-optimized versions of YFP and …

Journals Of Travels, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

Abstract

It is unfortunate that journals were not kept routinely for all of my [Stanley L. Welsh] expeditions that resulted in collections of plants that formed the bases for publications over the years. Only the record books and the specimens document most of the trips, and they are without detail of the events leading up to them or of those that transpired on them. The journals reproduced here show good intentions, which unfortunately were not fulfilled subsequently. The early field trips from Iowa State, accompanied by Dennis Anderson set the tone for later trips to Alaska, in 1965, 1966, 1968, …

Structural And Functional Divergence Of A 1-Mb Duplicated Region In The Soybean (Glycine Max) Genome And Comparison To An Orthologous Region From Phaseolus Vulgaris, Jer-Young Lin, Robert M. Stupar, Christian Hans, D. L. Hyten, Scott A. Jackson

Department of Agronomy and Horticulture: Faculty Publications

Soybean (Glycine max) has undergone at least two rounds of polyploidization, resulting in a paleopolyploid genome that is a mosaic of homoeologous regions. To determine the structural and functional impact of these duplications, we sequenced two ~1-Mb homoeologous regions of soybean, Gm8 and Gm15, derived from the most recent ~13 million year duplication event and the orthologous region from common bean (Phaseolus vulgaris), Pv5. We observed inversions leading to major structural variation and a bias between the two chromosome segments as Gm15 experienced more gene movement (gene retention rate of 81% in Gm15 versus 91% in …

Internal Transcribed Spacer (Its) Polymorphism In The Wild Primula (Primulaceae) Taxa Of Turkey, Mutlu Gültepe, Uğur Uzuner, Kami̇l Coşkunçelebi̇, Ali̇ Osman Beldüz, Sali̇h Terzi̇oğlu

Turkish Journal of Botany

Twenty-three populations belonging to 10 wild Primula L. (Primulaceae) taxa of Turkey, some of which are morphologically quite similar, were investigated based on nrDNA ITS regions. The plant materials were collected from different geographical areas of Anatolia in vegetation periods of 2005 and 2006. Total genomic DNAs were isolated from the healthy leaves of each population. The entire ITS regions of the populations were amplified by universal primers with the aid of a polymerase chain reaction (PCR), and then the PCR products were sequenced. Neighbour-Joining (NJ) and Maximum Parsimony (MP) trees were constructed in order to identify the relationships among …

Ovule Ontogenesis And Megagametophyte Development In Onobrychis Schahuensis Bornm. (Fabaceae), Abdolkarim Chehregani, Nayereh Tanomi

Turkish Journal of Botany

The ovule ontogenesis and the megasporogenesis events in Onobrychis schahuensis Bornm. were studied with light microscopy. The primordium is tetra-zonate and gives rise to an anatropous ovule. The archesporium may consist of one or more archesporial cells, but only one of them undergoes meiosis, forming a linear shaped tetrad. Normally, only a single megaspore is functional, which is located in the chalazal position, while the others degenerate very soon. The young ovule is hemianatropous but the mature one is anatropous, crassinucellar, and bitegmic; integuments form a zig-zag micropyle. A 7-celled embryo-sac is formed corresponding to the Polygonum type. The present …

Morphological, Karyological And Phylogenetic Evaluation Of Cyclotrichium: A Piece In The Tribe Mentheae Puzzle, Tuncay Di̇rmenci̇, Ekrem Dündar, Görkem Deni̇z, Turan Arabaci, Esra Marti̇n, Zi̇ba Jamzad

Turkish Journal of Botany

The genus Cyclotrichium, a member of the tribe Mentheae subtribe Menthinae (Lamiaceae, Nepetoideae), was analysed with respect to morphological revision, phylogenetic analysis, and cytogenetic properties. All species of the genus were investigated for morphological characters and ITS (internal transcribed spacers) of nrDNA sequence comparison (except C. hausknechtii for ITS). Six members of the genus were also analysed for chromosome numbers. The combined results strongly suggested that Cyclotrichium is a separate genus in Nepetoideae with distinct morphological, phylogenetic, and cytogenetic characteristics. For intrageneric phylogeny of Cyclotrichium, 3 groups were recognised: 1. C. niveum; 2. C. origanifolium; and 3. the remaining 6 …

Phylogenetic Relationships Of Some Turkish Crocus (Iridaceae) Taxa Based On Morphological And Anatomical Characters, Fati̇h Coşkun, Selami̇ Selvi̇, Fati̇h Satil

Turkish Journal of Botany

In this study, relationships among the 15 taxa of the genus Crocus L. distributed in Turkey were analysed using 29 morphological and 4 anatomical characters. Analysis of the data set utilising maximum parsimony criterion with Branch-and-Bound search algorithm yielded 32 most parsimonious trees. Bootstrap analysis with the majority rule consensus algorithm generated a consensus tree supporting some branches. Our data mostly did not agree with the previous sectional and serial treatments. The most interesting result was the condition of Crocus pallasii, which was previously included in the section Crocus. C. pallasii showed a sister group relationship with C. cancellatus from …

Don't Judge A Book By Its Cover: The Curious Case Of Wild Ginger Pollination, W. John Hayden

Biology Faculty Publications

What pollinates wild ginger? This seems like an easy question. The inconspicuous little flowers are held close to the forest floor, often completely hidden by a dense canopy of ginger leaves above. Flower color is rather drab, dominated by brown and maroon hues. Wind pollination seems completely unlikely and flowers pollinated by bees, butterflies, moths, or hummingbirds are always much more showy and accessible to these flying creatures. Flies, however, given their natural inclination to seek carrion as a food source for their babies (i.e. maggots), are often attracted to brown and maroon flowers. And because their actual quarry, animal …
