Lectotypification Of Symphytum Anatolicum (Boraginaceae), Burcu Tarikahya Hacioğlu, Sadik Eri̇k

Turkish Journal of Botany

Symphytum anatolicum Boiss. is an endemic species in the Flora of Turkey and the East Aegean Islands. It was first collected by d'Urville on the island of Cos in 1820 and named Symphytum asperrimum d'Urv. The plant was again collected by Boissier near İzmir (Smyrna) in 1842, and described by him as S. anatolicum in 1844. There are 4 collections mentioned in the protologue in Boissier's Flora Orientalis (1879). The herbarium specimen "Hab. in umbrosis montium circa Smyrnam", housed in G-Boiss. Herbarium, was chosen as lectotype as it best represents the species description.

Evaluation Of Heat Shock Protein 70a (Hsp70a) In Chlamydomonas Reinhardtii, Sarah Nicole Short Jan 2012

Evaluation Of Heat Shock Protein 70a (Hsp70a) In Chlamydomonas Reinhardtii, Sarah Nicole Short

Theses and Dissertations--Biosystems and Agricultural Engineering

Algae are being considered as a possible tool for carbon dioxide mitigation because they uptake carbon dioxide during photosynthesis. Using flue gas from a coal-fired power plant as a carbon source would allow the algae to remove CO2 from the flue gas before it is emitted into the atmosphere. Because algae do not grow well at the high temperature, low pH conditions presented by flue gas, the traditional approach has been to alter the flue gas to suit the needs of the algae; however, this work aimed to genetically modify the algae Chlamydomonas reinhardtii to grow better at less …


Glycerolipids And The Plant Cuticle Contribute To Plant Immunity, Qing-Ming Gao Jan 2012

Glycerolipids And The Plant Cuticle Contribute To Plant Immunity, Qing-Ming Gao

Theses and Dissertations--Plant Pathology

The conserved metabolites, oleic acid (18:1), a major monounsaturated fatty acid (FA), and glycerol-3-phosphate (G3P) are obligatory precursors of glycerolipid biosynthesis in plants. In Arabidopsis, the SSI2-encoded SACPD is the major isoform that contributes to 18:1 biosynthesis. Signaling induced upon reduction in oleic acid (18:1) levels not only upregulates salicylic acid (SA)-mediated responses but also inhibits jasmonic acid (JA)- inducible defenses. I examined the transcription profile of ssi2 plants and identified two transcription factors, WRKY50 and WRKY51. Although the ssi2 wrky50 and ssi2 wrky51 plants were constitutively upregulated in SA-derived signaling, they were restored in JAdependent defense signaling. Not only …


Glycerol-3-Phosphate Is A Novel Regulator Of Basal And Induced Defense Signaling In Plants, Bidisha Chanda Jan 2012

Glycerol-3-Phosphate Is A Novel Regulator Of Basal And Induced Defense Signaling In Plants, Bidisha Chanda

Theses and Dissertations--Plant Pathology

Plants use several strategies to defend themselves against microbial pathogens. These include basal resistance, which is induced in response to pathogen encoded effector proteins, and resistance (R) protein-mediated resistance that is activated upon direct or indirect recognition of pathogen encoded avirulence protein(s). The activation of Rmediated signaling is often associated with generation of a signal, which, upon its translocation to the distal uninfected parts, confers broad-spectrum immunity against related or unrelated pathogens. This phenomenon known as systemic acquired resistance (SAR) is one of the well-established forms of induced defense response. However, the molecular mechanism underlying SAR remains largely unknown. Induction …

An Evaluation Of The Species Status Of Physaria Intermedia (Brassicaceae), Katie Arp Jan 2012

An Evaluation Of The Species Status Of Physaria Intermedia (Brassicaceae), Katie Arp

Honors Program Theses

The taxonomy of the genus Physaria (Brassicaceae) has been continually under revision as many species groups have proved difficult to resolve. Physaria intermedia (S. Watson) O'Kane Al-Shehbaz, has been a species whose circumscription has more recently been questioned and in need of clarification. The uncertainty surrounding the species stemmed from a combination of its geographical distribution, inhabiting two disjunct locations, as well as some minor differences in morphology that warranted a closer look. The species had been described as occupying southern Utah, northern and eastern (in northern 2/3) Arizona and southwest New Mexico with the remaining specimens inhabiting an isolated …

Determining The Virulence Of Corn Pathogen Fusarium Verticillioides Utilizing Deletion Mutants Lacking Genes Fv_00027 Or Fv_Nps6, Abigail Zieman

Honors Program Theses

Fusarium verticillioides is an important fungal pathogen of com. Many pathogens have virulent genes which are genes that increase infectivity of the pathogen. After a bioinformatics study, it was determined that genes Fv _ 00027 and Fv _ NPS6 are potential virulent genes in F. verticillioides. To determine if either gene ·contributes to the virulence of the fungus, deletion mutants of F. verticillioides were created lacking either Fv _ 00027 or Fv _ NPS6 genes. These deletion mutants were utilized in an optimized com assay to determine the effect of infectivity on com. To test these deletion mutants, com seeds …

Effects Of Light Limitation On Plant-­Rhizobia And Plant-Mycorrhiza Interactions, Jess A. Millar Jan 2012

Effects Of Light Limitation On Plant-­Rhizobia And Plant-Mycorrhiza Interactions, Jess A. Millar

Anthós

Plants respond with a sink stimulation of photosynthesis when colonized by bacterial and fungal mutualists, which compensates for costs of carbohydrate allocation to the microbes. Problems may arise when light is limited and plants cannot increase photosynthesis. We hypothesize that under such conditions the costs for maintaining the mutualism outweigh the benefits, which ultimately turns the beneficial microbes into parasites exploiting resources and reducing host fitness. We study these plant-­‐microbe interactions under different light availabilities using lima bean plants, rhizobia (nitrogen-­‐fixing bacteria), and mycorrhizal fungi. In our study, we apply two levels of light (full light and light intensity reduced …

Dynamics Of The Sweetpotato Potyvirus Aphid Pathosystem In Louisiana, Everlyne Nafula Wosula Jan 2012

Dynamics Of The Sweetpotato Potyvirus Aphid Pathosystem In Louisiana, Everlyne Nafula Wosula

LSU Doctoral Dissertations

Sweetpotato potyviruses [Sweet potato feathery mottle virus (SPFMV), Sweet potato virus G (SPVG) and Sweet potato virus 2 (SPV2)] commonly infect sweetpotato and weedy morning glories in the USA. These viruses are transmitted in a non-persistent manner by various aphid species and cause up to 15% yield loss. Sweetpotato is vegetatively propagated, and in the USA growers are supplied with virus tested propagation material to minimize impact of viruses. However the rapid re-infection of these materials with viruses warranted further studies to determine factors that influence the epidemiology of these viruses. The objectives of this study were: (i) to determine …


Molecular Approaches To Detect And Control Cercospora Kikuchii In Soybeans, Ashok Kumar Chanda Jan 2012

Molecular Approaches To Detect And Control Cercospora Kikuchii In Soybeans, Ashok Kumar Chanda

LSU Doctoral Dissertations

Cercospora leaf blight (CLB) caused by Cercospora kikuchii, has become a troublesome disease in the southern United States. C. kikuchii produces a non-hostspecific phytotoxin and a pathogenicity factor known as cercosporin during infection of soybean. A quantitative real-time PCR assay was developed for detection and quantification of C. kikuchii. The sensitivity of detection is 1 pg of genomic DNA. The assay detected the presence of C. kikuchii in soybean leaves long before the appearance of disease symptoms. C. kikuchii DNA levels in soybean leaves increased slowly during early soybean development, followed by a quick increase at late reproductive stages. Results …

The Influence Of Biochar Production On Herbicide Sorption Characteristics, Sharon A. Clay, Douglas D. Malo Jan 2012

The Influence Of Biochar Production On Herbicide Sorption Characteristics, Sharon A. Clay, Douglas D. Malo

Agronomy, Horticulture and Plant Science Faculty Publications

Biochar is the by-product of a thermal process conducted under low oxygen or oxygen-free conditions (pyrolysis) to convert vegetative biomass to biofuel (Jha et al., 2010). There are a wide variety of end-products that can be manufactured depending on processing parameters and initial feedstocks (Bridgewater, 2003). The pyrolytic process parameters such as temperature, heating rate, and pressure can change the recovery amounts of each end-product, energy values of the bio-oils, and the physico-chemical properties of biochar (Yaman, 2004).
