Dr. Gerhard Buchbauer ohne dessen freundlichen, fundierten Hinweisen und Ratschlägen diese Arbeit wohl niemals in der vorliegenden Form zustande gekommen wäre. Nochmals Danke, Danke, Danke. Weiteres danke ich meinen Eltern, die sich alles vom Munde abgespart haben, um mir dieses Studium der Pharmazie erst zu ermöglichen, und deren unerschütterlicher Glaube an die Fähigkeiten ihrer Tochter, mich auch dann weitermachen ließ, wenn ich mal alles hinschmeissen wollte. Auch meiner Schwester Ira gebührt Dank, auch sie war mir immer eine Stütze und Hilfe, und immer war sie da, für einen guten Rat und ein offenes Ohr. Dank auch an meinen Sohn Igor, der mit viel Verständnis akzeptierte, dass in dieser Zeit meine Prioritäten an meiner Diplomarbeit waren, und mein Zeitbudget auch für ihn eingeschränkt war. Schliesslich last, but not least - Dank auch an meinen Mann Joseph, der mich auch dann ertragen hat, wenn ich eigentlich unerträglich war. 2 Abstract This review presents a general analysis of the scienthr information about nitrogen containing volatile organic compounds (N-VOC’s) in plants. -

The Two A-Dox Genes of Nicotiana Attenuata: Overlapping but Distinct Functions in Development and Stress Responses
Steppuhn et al. BMC Plant Biology 2010, 10:171 http://www.biomedcentral.com/1471-2229/10/171 RESEARCH ARTICLE Open Access The two a-dox genes of Nicotiana attenuata: overlapping but distinct functions in development and stress responses Anke Steppuhn2†, Emmanuel Gaquerel1†, Ian T Baldwin1* Abstract Background: Plant fatty acid a-dioxygenases (a-DOX) are oxylipin-forming enzymes induced by biotic and abiotic stresses, which also participate in developmental processes. In Nicotiana attenuata, herbivory strongly induces the expression of an a-dox1 gene. To determine its role, we silenced its expression using Agrobacterium-mediated plant transformation with an inverted repeat construct. More than half of the transformed lines showed a severe dwarf growth phenotype that was very similar to the phenotype of tomato plants mutated at a second a-dox isoform. This led us to identify the corresponding a-dox2 gene in N. attenuata and examine the regulation of both a-dox genes as well as the consequences of their silencing in plant development and anti-herbivore defense. Results: The transformed lines exhibiting a dwarf growth phenotype are co-silenced for both a-dox genes resulting in a nearly complete suppression of a-DOX activity, which is associated with increases in ABA, JA and anthocyanin levels, all metabolic signatures of oxidative stress. The other lines, only silenced for a-dox1, developed similarly to wild-type plants, exhibited a 40% reduction of a-DOX activity resulting in a 50% reduction of its main product in planta (2-HOT) and showed no signs of oxidative stress. In contrast to a-dox1, the expression of a-dox2 gene is not induced by wounding or elicitors in the oral secretions of Manduca sexta. -

Floristic Quality Assessment Report
FLORISTIC QUALITY ASSESSMENT IN INDIANA: THE CONCEPT, USE, AND DEVELOPMENT OF COEFFICIENTS OF CONSERVATISM Tulip poplar (Liriodendron tulipifera) the State tree of Indiana June 2004 Final Report for ARN A305-4-53 EPA Wetland Program Development Grant CD975586-01 Prepared by: Paul E. Rothrock, Ph.D. Taylor University Upland, IN 46989-1001 Introduction Since the early nineteenth century the Indiana landscape has undergone a massive transformation (Jackson 1997). In the pre-settlement period, Indiana was an almost unbroken blanket of forests, prairies, and wetlands. Much of the land was cleared, plowed, or drained for lumber, the raising of crops, and a range of urban and industrial activities. Indiana’s native biota is now restricted to relatively small and often isolated tracts across the State. This fragmentation and reduction of the State’s biological diversity has challenged Hoosiers to look carefully at how to monitor further changes within our remnant natural communities and how to effectively conserve and even restore many of these valuable places within our State. To meet this monitoring, conservation, and restoration challenge, one needs to develop a variety of appropriate analytical tools. Ideally these techniques should be simple to learn and apply, give consistent results between different observers, and be repeatable. Floristic Assessment, which includes metrics such as the Floristic Quality Index (FQI) and Mean C values, has gained wide acceptance among environmental scientists and decision-makers, land stewards, and restoration ecologists in Indiana’s neighboring states and regions: Illinois (Taft et al. 1997), Michigan (Herman et al. 1996), Missouri (Ladd 1996), and Wisconsin (Bernthal 2003) as well as northern Ohio (Andreas 1993) and southern Ontario (Oldham et al. -

Pollen tube growth rate (PTGR) may evolve rapidly due to pollen competition and haploid 28 selection, but many angiosperms are currently polyploid and all have polyploid histories. 29 Polyploidy should initially accelerate PTGR via “genotypic effects” of increased gene dosage 30 and heterozygosity on metabolic rates, but “nucleotypic effects” of genome size on cell size 31 should reduce PTGR. -
Transgressive Phenotypes and Generalist Pollination in the Floral Evolution of Nicotiana Polyploids
Title Transgressive phenotypes and generalist pollination in the floral evolution of Nicotiana polyploids Authors McCarthy, EW; Chase, MW; Knapp, S; Litt, A; Leitch, AR; Le Comber, SC Description This is the author's proof Date Submitted 2017-02-23 ARTICLES PUBLISHED: XX XX 2016 | ARTICLE NUMBER: 16119 | DOI: 10.1038/NPLANTS.2016.119 Transgressive phenotypes and generalist pollination in the floral evolution of Q1 Nicotiana polyploids Elizabeth W. McCarthy1,2,3†,MarkW.Chase2, Sandra Knapp3,AmyLitt4, Andrew R. Leitch1 and Steven C. Le Comber1* Polyploidy is an important driving force in angiosperm evolution, and much research has focused on genetic, epigenetic and transcriptomic responses to allopolyploidy. Nicotiana is an excellent system in which to study allopolyploidy because half of the species are allotetraploids of different ages, allowing us to examine the trajectory of floral evolution over time. Here, we study the effects of allopolyploidy on floral morphology in Nicotiana, using corolla tube measurements and geometric morphometrics to quantify petal shape. We show that polyploid morphological divergence from the intermediate phenotype expected (based on progenitor morphology) increases with time for floral limb shape and tube length, and that most polyploids are distinct or transgressive in at least one trait. In addition, we show that polyploids tend to evolve shorter and wider corolla tubes, suggesting that allopolyploidy could provide an escape from specialist pollination via reversion to more generalist pollination strategies. 1 olyploidy, or whole genome duplication (WGD), is an impor- transgressively larger14. In addition, autopolyploidy alone can 33 2 Ptant driving force in the evolution of angiosperms.
