Molecular Phylogeny And Biogeography Of The South American Genus Metrodorea (Rutaceae), Pedro Dias, Renata Giassi Udulutsch, Jose Rubens Pirani
Turkish Journal of Botany
The genus Metrodorea (Rutaceae), with 6 species, has representatives that vary from small shrubs to tall trees, and its leaf sheaths make it unique in the family; it is restricted to South America, with species diversity concentrated in Brazil. In this study, we applied Bayesian and parsimony methods to infer the molecular phylogeny of Metrodorea, and cladistic biogeographic methods to propose an area cladogram for the genus. All results supported Metrodorea as monophyletic, and the presence of leaf sheaths is reinforced as its key diagnostic feature. Bayesian and parsimony trees were identical for relationships within Metrodorea. The crown clade (M. …

Turkish Journal of Botany
We describe and illustrate a new species of Prosthechea from Costa Rica. The species is similar to Prosthechea ionocentra, but it is easily distinguishable by its inflorescence originating from the penultimate mature pseudobulb; its purple spotted sepals and petals; the cordate, acute labellum; the disc with two longer, narrower keels; the stigmatic arms of the column, which are convergent and rounded; and the narrower stigma. Differences from other related species are given and discussed. Data on distribution, habitat and ecology, etymology, and phenology are provided. An updated key to the species of the Prosthechea prismatocarpa complex is presented.

Functional Analysis Of Drought-Resistant Genes In Barley Using Vigs, Natalie Catherine Martin
Honors Program Theses
The following study analyzed the role of the gamma-aminobutyric acid transaminase (GABAT) gene in the response of barley plants to drought stress. Expression of GABAT in barley was suppressed using virus-induced gene silencing (VIGS). In VIGS, an RNA virus is used to replicate a small portion of the target RNA. In this study, barley stripe mosaic virus (BSMV), that carries a piece of the GABAT gene to infect barley, was used. As the virus replicates inside infected barley plants, it also makes RNA that is complementary to GABAT messenger RNA (mRNA) that is normally made by the host. The presence …

Analysis Of Ipomoea (Morning Glory) Leaf Mutants, Abigail Anne Lee
Honors Program Theses
Ipomoea (morning glory) is the largest genus in the family Convolvulaceae. Cultivation of morning glory plants began in the late Edo period in Japan, and this horticultural success resulted in thousands of plants with varying floral displays. In addition to the different flower morphologies, leaf shape is highly variable within this family making it an ideal group in which to study leaf development. We selected four mutants that vary in lobe number and lobe depth: 1) Tokyo Standard (TKS1065; wild-type; 3 lobes), yellow maple (ym1018; 5 lobes), delicate maple (dlm620; 5 deep lobes), and maple willow …

Genetic And Functional Analysis Of Host Genes Involved In Pathogenic And Symbiotic Legume-Microbe Interactions, Fang Tang
Theses and Dissertations--Plant and Soil Sciences
Legumes form symbiotic and pathogenic interactions with microbes. Understanding the molecular mechanisms underlying the legume-microbe interactions would help us to improve crop production in a sustainable manner. This thesis covers two independent research projects. The first project was to study the role of alternative splicing in RCT1-mediated disease resistance. RCT1 is a TIR-NBS-LRR-type plant resistance (R) gene in Medicago truncatula that confers broad-spectrum resistance to Colletotrichum trifolii, a fungal pathogen that causes anthracnose disease in Medicago. RCT1 undergoes alternative splicing at both coding and 3'-untranslated regions, thereby producing multiple transcript variants in its expression profile. …

Plant Functional Types In Mediterranean Enclaves In Western Black Sea Region Of Turkey, Emi̇re Elmas, Hamdi̇ Güray Kutbay
Turkish Journal of Botany
Mediterranean-type communities of the Sinop Peninsula were classified as plant functional types (PFTs) by the help of some vegetative and generative traits and 5 PFTs were determined. Some vegetative (specific leaf area (SLA), leaf texture, leaf P concentration, deciduousness, hairiness) and generative (reproductive phenology and fruit type) traits were found to be significant for discrimination of PFTs. It was found that PFT3 and PFT4 were associated with leaf texture, SLA, and leaf P concentration. PFT2 was associated with deciduousness, hairiness, and reproductive phenology, while PFT1 was only associated with fruit type. Generative traits were found to be associated with PFT1 …

Influence Of Foliar Application Of Silicon On Chlorophyll Fluorescence, Photosynthetic Pigments, And Growth In Water-Stressed Wheat Cultivars Differing In Drought Tolerance, Kobra Maghsoudi, Yahya Emam, Muhammad Ashraf
Turkish Journal of Botany
The influence of foliar application of silicon (Si) on chlorophyll contents, chlorophyll fluorescence, and growth of four wheat cultivars differing in drought tolerance (Sirvan and Chamran, as relatively drought tolerant, and Shiraz and Marvdasht, as drought sensitive) was examined under water deficit (100% and 40% F.C.) created in a greenhouse. The results showed that water deficit decreased shoot and root lengths, shoot dry weight, root dry weight, water utilization efficiency, chlorophyll a and b, and chlorophyll stability index. In contrast, foliar application of Si improved plant growth parameters and chlorophyll pigment concentration under water deficit; however, it did not significantly …
