Abstract:
Wet-chemical syntheses have been applied to the production of ceramic powders, with the aim of tailoring compositional and micro/nanostructural features, as an imperative requirement toward the elaboration of ceramic components with improved functional or even structural properties. Three syntheses are here presented and discussed, respectively concerning a purephased, nanostructured YAG powder, a biphasic Al2O3-YAG composite and three-phased Al2O3- YAG-ZrO2 material. In particular, this paper is aimed to illustrate the path followed from the set-up of the easier synthesis of the mono-phased system to the definition of the advanced procedures for the production of more and more complex compositions.

Abstract:
Bottom-up strategies have allowed the synthesis of “molecular” nanographenes with full control over size, shape and functionality. In recent years, the progress on wet chemical approaches, oxidative cyclodehydrogenation amongst all, has been the foundation to the synthesis of an impressive number of soluble and well-defined molecular nanographenes. The level of control over nanographene syntheses has allowed a fine-tuning of the photophysical and electrochemical properties and, in turn, has a compelling potential in the field of material science. In this regard, understanding and harnessing the competition between electron transfer and energy transfer in nanographenic systems is of utmost importance. However, a comprehensive structure-property relationship remains still an open aspect. In the present review we describe a large variety of hexa-peri-hexabenzocoronene (HBC)-based nanographenes obtained through wet chemical strategies and linked – either covalently or non-covalently – to porphyrins, rylenes, fullerenes, etc. Particular attention was placed on the optical, electrochemical and excited-state properties.

Abstract:
Theories about the origin of life require chemical pathways that allow formation of life’s key building blocks under prebiotically plausible conditions. Complex molecules like RNA must have originated from small molecules whose reactivity was guided by physico-chemical processes. RNA is constructed from purine and pyrimidine nucleosides, both of which are required for accurate information transfer, and thus Darwinian evolution. Separate pathways to purines and pyrimidines have been reported, but their concurrent syntheses remain a challenge. We report the synthesis of the pyrimidine nucleosides from small molecules and ribose, driven solely by wet-dry cycles. In the presence of phosphate-containing minerals, 5′-mono- and diphosphates also form selectively in one-pot reactions. The pathway is compatible with purine synthesis, allowing the concurrent formation of all Watson-Crick bases.

Abstract:
Silver nanoparticles (AgNPs) are well-known for their antimicrobial effects and several groups are proposing them as active agents to fight antimicrobial resistance. A wide variety of methods is available for nanoparticle synthesis, affording a broad spectrum of chemical and physical properties. In this work, we report on AgNPs produced by laser ablation synthesis in solution (LASiS), discussing the major features of this approach. Laser ablation synthesis is one of the best candidates, as compared to wet-chemical syntheses, for preparing Ag nano-antimicrobials. In fact, this method allows the preparation of stable Ag colloids in pure solvents without using either capping and stabilizing agents or reductants. LASiS produces AgNPs, which can be more suitable for medical and food-related applications where it is important to use non-toxic chemicals and materials for humans. In addition, laser ablation allows for achieving nanoparticles with different properties according to experimental laser parameters, thus influencing antibacterial mechanisms. However, the concentration obtained by laser-generated AgNP colloids is often low, and it is hard to implement them on an industrial scale. To obtain interesting concentrations for final applications, it is necessary to exploit high-energy lasers, which are quite expensive. In this review, we discuss the pros and cons of the use of laser ablation synthesis for the production of Ag antimicrobial colloids, taking into account applications in the food packaging field.

Abstract:
Bismuth titanate syntheses using wet chemical methods are comparatively time-consuming and require long durations for completion using the well-studied sol-gel method. In this work, we use microwave initiated combustion method to produce ultra-thin bismuth titanate nanosheets. This method reduces the time required for the synthesis down to minutes, when compared to hours or days in most other methods. The thickness of the synthesized sheets were tuned by adding polyethylene glycol as a capping agent, which in turn affects the band gap and subsequently, their photocatalytic properties. The samples were characterized using x-ray diffraction, transmission electron microscopy and absorption spectrophotometry. Photocatalytic effect of the synthesized bismuth titanate nanosheets on methylene blue dye also studied and variation of band gap depending on thickness of the nanosheets were observed.

Abstract:
The ever-growing demand for high performance energy storage systems has become a driving force for seeking the ideal materials to deliver superior efficacy, and graphene oxide (GO) and vanadium oxide are such two promising nanostructured materials. However, neither of them has been widely adopted in the marketplace at the current stage, mainly limited by their costeffectiveness. While GO and vanadium oxide have been proved to outperform existing materials in the lab-scale studies, the more expensive and less scalable synthesis methods discourage industrial manufacturers from adopting the two materials. The research herein focuses on the novel low cost and scalable wet chemical synthesis methods, which may lead GO and vanadium oxide to greater commercial success. The PhD thesis generally is unfolded into two parts. In the first part, a simple hydrothermal method to synthesize tungsten-doped V6O13 is reported. The introduction of tungsten dopant can have a significant impact on the nanostructure evolution of vanadium oxide during hydrothermal reaction, which results in the formation of nanocrystalline structure. A realtime characterization of the hydrothermal reaction process was employed to reveal the complex phase changes of vanadium oxide in the course, which can be important guidance for controlling the product quality in larger-scale production. Moreover, when applied to lithium ion batteries (LIBs), the doped nanocrystalline V6O13-based electrode can provide better battery performance than the undoped V6O13. In the second part, graphite oxide route to synthesize graphene oxide is investigated in terms of the choices of graphite sources (expanded graphite, graphite intercalation compound and natural graphite), pre-treatment of expanded graphite (microwave-induced expansion of graphite in different atmospheres), reaction temperature, and post-processing of GO. It was found that the expanded graphite prepared in ambient air had higher dispersibility in organic solvent and finally led to higher GO yield, through the modified Hummers oxidation, than those prepared in pure carbon dioxide or argon. This is possibly due to the introduction of extra oxygen-containing functionalities accompanied by the rapid heating of graphite. We also found that graphite intercalation compound was a more suitable starting material for making large-sized GO at room temperature. One distinguishing feature of the GO produced at room temperature is that it has more thermal labile oxygen functional groups which allows the facile restoration of electrical conductivity via a mild thermal annealing. This characteristic will be very helpful to better combine GO with the electroactive particles in LIBs and thus benefit the overall battery performance. Finally, we further compared the cost-effectiveness between the room temperature synthesis method and the lower temperature method, using commercial expanded graphite powder as the graphite source. It revealed that the GO synthesized at room temperature could regain more conductive sp2 carbon and reached the same level of electrical conductivity through thermal or chemical reduction. Therefore, the room temperature method can produce conductive graphene for energy storage applications in a more cost-effective manner. On balance, this PhD thesis further develops the scalable wet chemical production of GO and vanadium oxide for energy storage by systematically investigating the key synthesis parameters and establishing the improved protocols. Ultimately, this work is anticipated to push forward the commercialization of GO and vanadium oxide in the field of energy storage in the near future.

Full text
Abstract:
Les électrolytes solides sont aujourd’hui considérés comme la clé pour le développement des nouvelles générations de batteries. Deux types d’électrolytes solides ont majoritairement été étudiés, les polymères et les inorganiques, mais leurs performances restent limitées. Une piste prometteuse pour obtenir des électrolytes performants est d’utiliser des particules inorganiques incorporées dans une matrice polymère afin de former un électrolyte hybride. Parmi les matériaux inorganiques possibles, la famille des sulfures (Li3PS4, Li6PS5X avec X= Cl,Br, I) présente des conductivités ioniques très élevées. Cependant, ces matériaux sont généralement obtenus par voie solide menant à des particules micrométriques agrégées. De plus, bien que des synthèses en solution aient été récemment mises en évidence, le potentiel de contrôle de la taille, de la morphologie et de la prévention de leur agrégation n’est pas exploité. L’objectif de cette thèse est de mettre au point une méthodologie de synthèse de sulfures permettant de contrôler la taille, la morphologie et l’agrégation des particules afin de permettre leur incorporation dans une phase polymère. Plusieurs voies de synthèse en solution ont été développées afin de s’affranchir des limitations cinétiques de la synthèse conventionnelle. Ces différentes méthodes de synthèse ont permis d’obtenir un large panel de particules avec des morphologies et des taux d’agrégation différents. L’impact de la taille et de la morphologie des particules sur les performances électrochimiques des électrolytes a été étudié. Les électrolytes les plus performants ont été testés dans des formulations hybrides ainsi que dans des cellules électrochimiques tout solide complètes avec une anode Li/In
Solid electrolytes are now considered to be the key to the development of new generations of batteries. Two types of solid electrolyte have mainly been studied, polymers and inorganics, but their performance remains limited. One promising way of obtaining high-performance electrolytes is to use inorganic particles incorporated into a polymer matrix to form a hybrid electrolyte. Among the possible inorganic materials, the sulfide family (Li3PS4, Li6PS5X with X= Cl, Br, I) has very high ionic conductivities. However, these materials are generally obtained by the solid route, leading to aggregated micrometric particles. Furthermore, although solution syntheses have recently been demonstrated, the potential to control their size, morphology and prevent aggregation has not been exploited. The aim of this thesis is to develop a methodology for the synthesis of sulfides that enables the size, morphology and aggregation of particles to be controlled so that they can be incorporated into a polymer phase. Several solution synthesis routes were developed in order to overcome the kinetic limitations of conventional synthesis. These different synthesis methods have produced a wide range of particles with different morphologies and aggregation rates. The impact of particle size and morphology on the electrochemical performance of the electrolytes was studied. The best performing electrolytes were tested in hybrid formulations as well as in complete all-solid state electrochemical cells with a Li/In anode

Abstract:
The economical feasibility of commercial, single-junction solar cells is limited by high costs and limited efficiencies. New solar cell concepts and materials are sought to decrease the production costs and increase the efficiency. Intermediate band solar cells (IBSCs) show a promising concept for increased efficiency up to 46.77% as they employ three band gaps that can be matched to the solar spectrum to minimize fundamental losses. Doping of copper gallium disulphide (CuGaS2) with transition metals like Fe and Ni to high concentrations can theoretically form an intermediate band (IB), which for Fe doping gives nearly optimal band gaps for IBSC applications. Copper gallium disulphide is synthesized in an environmentally friendly, inexpensive and simple hydrothermal synthesis which may contribute to decreased costs of solar cell production.The hydrothermal synthesis is developed to produce copper gallium disulphide from copper(I) chloride (CuCl), gallium(III) chloride (GaCl3) and excess thiourea (Tu) (SC(NH2)2) in deionized water. The influence of varying synthesis parameters on product purity, yield and morphology has been investigated through X-ray diffraction (XRD) and scanning electron microscopy (SEM). Energy dispersive X-ray spectroscopy (EDS) is used to investigate doping of copper gallium disulphide and identify particle morphologies formed by different phases. Formation of copper gallium disulphide proceeds through slow decomposition of Tu, driven by an equilibrium shift due to hydrogen disulphide (H2S) evolution and precipitation of sulphides like the intermediate phase digenite (Cu2-δS) into which Ga3+ ions are incorporated. An additional impurity of copper(II) sulphide (CuS) is commonly formed, and gallium(III) hydroxyoxide (GaO(OH)) forms at pH > 0.5. Products of high purity and yield are obtained at 250 °C with concentrations above 0.060 M copper(I) chloride and gallium(III) chloride with the complexing agent 1-pentanethiol, and 0.319 M without 1-pentanethiol. Introducing nickel(II) chloride (NiCl2) or iron(III) chloride (FeCl3) in the hydrothermal synthesis forms vaesite (NiS2) or iron pyrite (FeS2) impurities, respectively, and copper gallium disulphide is not doped to a desirable concentration for IB formation.Color variations in the products reveal off-stoichiometries which contribute to a wide range of particle and crystallite morphologies within each product. Yellow, stoichiometric copper gallium disulphide particles have been deposited on a Si(100) substrate and growth of a red, Ga-rich film was achieved with 1-pentanethiol. These products were subject to photoluminescence spectroscopy (PL) along with off-stoichiometric powders of doped and undoped products, but no luminescence was obtained, possibly due to high defect densities and non-radiative recombination. Dispersions of powders were also subject to absorption spectroscopy which indicate extensive scattering due to wide ranges of particle sizes. The morphology of powder products shows particularly large variations within and between the products. Nanoplate and pyramidal crystallites are produced through nucleation and growth to form network structures and polycrystalline spheres, rods and rose-like particles, which along with the crystallites have varying irregularities and sizes.

Full text
Abstract:
In this work a new wet-chemical method of preparing tungsten oxide thin films is described. This involves the dissolution of tungsten metal in aqueous hydrogen peroxide and reaction with acetic acid to form an alcohol-soluble precursor. All synthesis stages of this new precursor, termed peroxotungstic ethoxide, are characterized to determine possible reactions. The chemical and microstructural evolution of films is described as a function of firing temperature, utilizing infrared spectroscopy, diffraction and other optical data. A novel method of increasing the crack-free thickness of the films is given: a combination of oxalic acid dihydrate as a solution additive and film firing under controlled humidity. With this combination, fired crack-free films up to one micron in thickness were prepared. Oxalic acid dihydrate roughened and also caused crystallization of these films at lower temperatures (250°C) than expected. These rougher films exhibited an improved electrochromic response, as measured by optical and electrochemical characterizations.

Abstract:
Doped ZnO nanoparticles were synthesized by three different methods – electrochemical deposition under oxidizing conditions (EDOC) , combustion method and wet chemical synthesis – for investigating the oxygen gas sensing response. Ga-doped ZnO was mostly synthesized but also In-doped ZnO was made. The samples were analyzed by XRD, SEM, EDX and TEM. Gas response curves are given alongside with Langmuir fitted curves and data for pure ZnO and Ga-doped ZnO. DFT quantum chemical investigation of cluster models ZnO nanoparticles were performed to evaluate defect effects and oxygen and nitrogen dioxide reactions with the ZnO surface. Defects were investigated by DOS and HOMO-LUMO plots , and are oxygen vacancy, zinc vacancy, zinc interstitial and gallium doping by replacing zinc with gallium. Oxygen and nitrogen dioxide reactions were investigated by computing Mulliken charges, bond lengths, DOS spectra and HOMO-LUMO plots.

Abstract:
Depression currently affects more than 15% of the population overall, and it is striking people at increasingly younger ages. Depression is all too familiar, yet this condition remains shrouded in mystery, confusion, and fear. What is depression, exactly? How is it different from sadness? It is said that depression is a “chemical imbalance,” but what does that really mean? Which chemicals are involved, and how are they imbalanced? Why is it that just as more research and treatment resources have been poured into combating depression, its personal and economic toll has actually grown? What, then, is fueling the epidemic of depression? Is there anything that can be done to stop it? This book cuts through the confusion to address the core of these and other matters. It offers a practical research synthesis that bridges clinical science, clinical practice, and everyday life. Written in the pithy, straightforward style of Oxford University Press’ What Everyone Needs to Know series, this book is the essential go-to guide both for understanding what we know about the causes of depression and the depression epidemic and for learning what to do about it; the book includes material on how to recognize depression in yourself, a family member, or a friend and how to navigate life after depression. Written for all those who struggle with depression, their loved ones, mental health professionals, and the wider public, this book offers guidance for navigating the bewildering marketplace of treatment options and combatting the misinformation and myths that still surround this condition.

Full text
Abstract:
The public is more interested in agricultural and food issues than ever before, as is evident in the many agricultural controversies debated in the media. Why is it that some people embrace new agricultural technologies while others steadfastly defend traditional farming methods? Why do some prefer to buy food grown around the world while others patronize small, local farmers? In the debates about organic food, genetically modified organisms, and farm animal welfare, it is not always clear what the scientific literature actually says. To understand these controversies, the authors encourage readers to develop first an appreciation for why two equally intelligent and well-intentioned people can form radically different notions about food. Sometimes the disputes are scientific in nature, and sometimes they arise from conflicting ethical views. This book confronts the most controversial issues in agriculture by first explaining the principles of both sides of the debate, and then guiding readers through the scientific literature so that they may form their own educated opinions. Is food safe if the farm used pesticides, or are organic foods truly better for your health? Are chemical fertilizers sustainable, or are we producing cheap food today at the expense of future generations? What foods should we eat to have a smaller carbon footprint? Is genetically-modified food the key to global food security, and does it give corporations too much market power? Is the prevalence of corn throughout the food system the result of farm subsidies? Does buying local food stimulate the local economy? Why are so many farm animals raised indoors, and should antibiotics be given to livestock? These are the issues addressed in Agricultural and Food Controversies: What Everyone Needs to Know. While it doesn't claim to have all the answers, it provides a synthesis of research and popular opinions on both sides of these important issues, allowing readers to decide what they value and believe for themselves.

Abstract:
This multi-disciplinary study examines the exceptional Turkey red textile dyeing process and product. Prized for its brilliant colour and durability, yet notoriously difficult to produce, the textile was consumed locally and exported around the world. Considered one of the first instances of industrial espionage, the expansion of the Turkey red industry is closely linked to the Industrial Revolution and the emergence of a new global economy. Significant technological advances in chemistry and dyeing were motivated by the demands of Turkey red dyers and printers, who were located primarily in the west of Scotland, the north of England, and around Mulhouse, Switzerland. This book explores the arc of the Turkey red industry, the evolution of the process through key producers and technical developments, the complicated printing process, and finishes with an examination of significant Turkey red collections and a selection of object case studies. The chemistry of the process is described in an accessible, contextual manner, highlighting the significance of the distinctive technique that yielded the best red attainable on cotton. Drawing on both historical and contemporary study, Turkey Red presents significant new research on the material characterisation of this fascinating, eye-catching textile, and offers an in-depth historical example of the global effect of textile consumption. This book is the most comprehensive examination of Turkey red textiles and dyeing to date. The bright red cotton, renowned for its brilliant hue and resistance to fading, was a household name during the nineteenth century and a major industrial product. Following an extensive analysis of historical dyeing methods and texts on the topic, Wertz proposes a process-based definition of Turkey red as cotton fibers pre-treated with oil, then aluminium, and dyed with madder or synthetic alizarin and calcium. A discussion of textile dyeing processes fitting this definition, along with trade accounts and other documentary evidence, reveals the possible origins of Turkey red in India. The dyeing process is presented along with a discussion of the chemical interactions taking place, and how this contributes to the particular fastness of the final product. Its resistance to bleaching and wash fading made it especially useful for domestic textiles and high-use garments. These properties, and the dyeing process itself, meant that printed Turkey red could only be obtained through discharging fully-dyed cloth of the red before selectively adding other colors. Turkey red both drove and benefited from technological innovations like chlorine bleaching, the synthesis of alizarin, and the development of Turkey red oil, as well as the mechanization and increased production capacity of the Industrial Revolution. Archival material provides insight into the nineteenth-century industry and how international markets made it a global product. A survey of Turkey red collection objects, paintings, photographs, and other materials showcases its appeal, versatility, and durability as a textile.

Abstract:
Preparation of stable nanofluids is the first step and key issue of nanofluid research and application. A wet chemical route for controllable synthesizing of nanofluids was developed and three kinds of nanofluids were prepared using this method. Aqueous nanofluids containing CuO nanoparticle clusters with different aggregating degree were controllably synthesized by changing the reflux reaction time. Nanofluids consisting of CuS hollow spheres with different size and shell thickness were produced. Ag nanofluids with different cluster size were manipulated as well. The synthesis mechanism for the wet chemical route was proposed.

Full text
Abstract:
Phytophagous insects respond to chemicals from their host plants in a number of ways, including orientation or attraction in response to volatiles produced by plants. Orientation to odors from host plants may occur in order to locate food, mates, or oviposition sites. A detailed understanding of these behaviors are the chemical stimuli evoking them may provide useful means for attracting and trapping insect pests of crop plants. Heliothine moths (Helicoverpa and Heliothis herein) include a number of major pests of cultivated crop plants throughout the world. In North America, these include Heliothis virescens and Helicoverpa zea. In much of Eurasia (including Israel) Australia, and Africa, these include Helicoverpa armigera and Helicoverpa peltigera. These 4 species of concern all are attracted to odorants from host plants (Tingle and Mitchell 2992, Mitchell et al 1991, 1992 BARD feasibility study report). Host plant chemicals also play a role in the sexual behavior of Helicoverpa species. Synthesis and possibly release of sex pheromone in H. zea and H. phloxiphaga is stimulated by kairomones from hosts plants (Raina 1988, 1992). Pheromona scent marking on host plants also occurs in H. virescens and H. zea. Studies of several other insects, including the cabbage looper Trichoplusia ni, have a variety of other behaviors may occur in association with host plants, including the use of plants as sexual rendesvous sites and of direct involvement of plant chemicals in sexual behavior. Some pest species of moths also may use host plants as adult food sources. These studies were undertaken to develop a more thorough understanding of how Heliothis/Helicoverpa moths use host plant odorants to locate and select foods, mates, and oviposition sites. We used Heliothis virescens and Helicoverpa zea in Florida, and Helicoverpa armigera and Helicoverpa peltigera in Israel as objects of study because of their pest status. It is hoped that such an understanding will provide direction for work to discover and develop novel means to control these pests through behavioral manipulation. The specific objectives of the proposal were to 1) identify host odor affects on known Heliothine sexual behavior, 2) identify novel sexual behavior that is how dependent, 3) isolate and characterize host kairomones important to pest Heliothine host and mate-location behavior, and 4) investigate female attraction to males.

Dinger, Eric, and Eric Dinger. Analysis of stream types in Klamath Network parks based on physical habitat and chemical characters. National Park Service, 2024. http://dx.doi.org/10.36967/2306085.

Full text
Abstract:
This is the first ?Analysis and Synthesis? report required by the Klamath Inventory and Monitoring Network?s stream monitoring protocol. This report synthesizes the physical and chemical attributes of streams surveyed by the Klamath Network between 2011 and 2018 in the following parks: Crater Lake National Park, Lassen Volcanic National Park, Whiskeytown National Recreation Area, Redwood National and State Parks, and Oregon Caves National Monument and Preserve). Where possible, it categorizes individual streams into groups using multivariate exploratory analyses and assigns statistical significance to the groups via Similarity Profile analyses. Streams are sorted into similar groups for eight different metric categories: Channel Morphology (e.g., bank angle, width, depth, etc.), Habitat Complexity (amount and types of cover), Large Woody Debris (categories of length and diameter of fallen wood), Riparian Characters (e.g., percent cover of tree, shrub, and groundcover types), Slope and Sinuosity, Stream Substrate (e.g., percent fine substrate, median substrate size), Water Chemistry (e.g., nutrients and salts), and Water Quality (e.g., dissolved oxygen, turbidity). Secondary to the categorization of streams within each park, the streams are compared among parks to identify which parks may have similar streams. Similar streams potentially share both common stressors and common management practices for resource management. The analyses in this report form the foundation of future work; they are ?basic? results. Follow-up work will use these basic results more fully, such as for analyses that incorporate biological data and support trend reports. The main body of the report presents a high-level overview of individual park results and inter-park comparisons. The appendices present full results for each park, including numerous figures and maps. Oregon Caves National Monument and Preserve results are limited by small sample size (n = 3) and the hand-selected sampling scheme we used instead of a probabilistic sampling scheme. However, including Oregon Caves? sites in this analysis puts them into a larger network context.

Sela, Shlomo, and Michael McClelland. Desiccation Tolerance in Salmonella and its Implications. United States Department of Agriculture, May 2013. http://dx.doi.org/10.32747/2013.7594389.bard.

Full text
Abstract:
Salmonella enterica is a worldwide food-borne pathogen, which regularly causes large outbreaks of food poisoning. Recent outbreaks linked to consumption of contaminated foods with low water-activity, have raised interest in understanding the factors that control fitness of this pathogen to dry environment. Consequently, the general objective of this study was to extend our knowledge on desiccation tolerance and long-term persistence of Salmonella. We discovered that dehydrated STm entered into a viable-but-nonculturable state, and that addition of chloramphenicol reduced bacterial survival. This finding implied that adaptation to desiccation stress requires de-novo protein synthesis. We also discovered that dried STm cells develop cross-tolerance to multiple stresses that the pathogen might encounter in the agriculture/food environment, such as high or low temperatures, salt, and various disinfectants. These findings have important implications for food safety because they demonstrate the limitations of chemical and physical treatments currently utilized by the food industry to completely inactivate Salmonella. In order to identify genes involved in desiccation stress tolerance, we employed transcriptomic analysis of dehydrated and wet cells and direct screening of knock-out mutant and transposon libraries. Transcriptomic analysis revealed that dehydration induced expression of ninety genes and down-regulated seven. Ribosomal structural genes represented the most abundant functional group with a relatively higher transcription during dehydration. Other large classes of induced functional groups included genes involved in amino acid metabolism, energy production, ion transport, transcription, and stress response. Initial genetic analysis of a number of up-regulated genes was carried out). It was found that mutations in rpoS, yahO, aceA, nifU, rpoE, ddg,fnr and kdpE significantly compromised desiccation tolerance, supporting their role in desiccation stress response.

Schaffer, Arthur A., and Jocelyn Rose. Understanding Cuticle Development in Tomato through the Study of Novel Germplasm with Malformed Cuticles. United States Department of Agriculture, June 2013. http://dx.doi.org/10.32747/2013.7593401.bard.

Full text
Abstract:
Plant cuticle development and metabolism are still poorly understood, partly due to the chemical complexity of the cuticular layer. The overall research objective was to broaden and deepen our understanding of tomato fruit cuticle development by analyzing novel germplasm with cuticular malformations and by studying the transcriptome and proteome of the fruit epidermal tissues, as strategies to overcome the challenges posed by the recalcitrance of the biological system. During the project we succeeded in identifying two genes with major impact on cuticle development. One of these encoded the first cutin synthase to be identified in plants, a metabolic step that had been a black box in cutin synthesis. In addition genes controlling the triterpenoid components of the cuticle were identified and, most interestingly, genetic variability for this component was identified among the wild tomato species germplasm. Additional germplasm was developed based on interspecific crosses that will allow for the future characterization of modifier genes that interact with the microfissuring gene (CWP) to promote or inhibit fruit cracking. One of the major accomplishments of the joint project was the integrated transcriptomic and proteomic analysis of the fruit cuticle and underlying tissues which allows for the identification of the pericarp cell layers responsible for the extracellular, cuticle-localized protein component. The results of the project have expanded our understanding of tomato fruit cuticle development and its genetic control. In addition, germplasm developed will be useful in developing tomato varieties resistant to cracking, on the one hand, and varieties useful for the dehydration industry on the other.
