Streszczenie:
The prooxidant capacity of rapeseed, sunflower, soybean, and olive oil was determined before and after heating at a temperature of 180°C for 2, 4, and 6 hours. It was quantified as losses of α-tocopherol caused by the studied oils during 24-h incubation of their acetone–methanol solutions with addition of α-tocopherol at 30°C, whereas the decrease in α-tocopherol concentration was studied as a decrease in antioxidant capacity determined by the spectrophotometric DPPH (2,2-diphenyl-1-picrylhydrazyl) method. During heating of all the studied plant oils, the prooxidant capacity grew due to the formation of reactive lipid oxidation products, but, except the sunflower oil, it did not depend on the time of heating – after the initiatory increase, the prooxidant capacity typically remained approximately constant or decreased. The prooxidant capacity of the heated oils ranged from 58 mg to 360 mg α-tocopherol/kg and decreased in the order soybean oil > rapeseed oil > olive oil ≈ sunflower oil. It did not correlate with the content of polymerised triacylglycerols (except the sunflower oil) and was generally higher than the residual content of α-tocopherol.

The Cosmetic Ingredient Review Expert Panel (Panel) assessed the safety of 244 plant-derived fatty acid oils as used in cosmetics. Oils are used in a wide variety of cosmetic products for their skin conditioning, occlusive, emollient, and moisturizing properties. Since many of these oils are edible, and their systemic toxicity potential is low, the review focused on potential dermal effects. The Panel concluded that the 244 plant-derived fatty acid oils are safe as used in cosmetics.

Streszczenie:
Essential oils’ therapeutic potential is highly recognized, with many applications rising due to reported anti-inflammatory, cardioprotective, neuroprotective, anti-aging, and anti-cancer effects. Nevertheless, clinical translation still remains a challenge, mainly due to essential oils’ volatility and low water solubility and stability. The present review gathers relevant information and postulates on the potential application of plant nanovesicles to effectively deliver essential oils to target organs. Indeed, plant nanovesicles are emerging as alternatives to mammalian vesicles and synthetic carriers due to their safety, stability, non-toxicity, and low immunogenicity. Moreover, they can be produced on a large scale from various plant parts, enabling an easier, more rapid, and less costly industrial application that could add value to waste products and boost the circular economy. Importantly, the use of plant nanovesicles as delivery platforms could increase essential oils’ bioavailability and improve chemical stability while reducing volatility and toxicity issues. Additionally, using targeting strategies, essential oils’ selectivity, drug delivery, and efficacy could be improved, ultimately leading to dose reduction and patient compliance. Bearing this in mind, information on current pharmaceutical technologies available to enable distinct routes of administration of loaded vesicles is also discussed.

Streszczenie:
Horticultural oils are among the safest of pesticides. Lack of product identification through the label makes it difficult for the field user to know what product was actually used in experimental studies. A minimum standard for product identification is suggested. Phytotoxicity, while relatively uncommon, continues to cause fears on the part of nurserymen and spray contractors. Factors that must be taken into account before spraying oil include dosage, timing with regard to plant phenological development and climatic conditions, and an awareness of sensitive plant species. A list of sensitive plants is given. A new expression of pesticide resistance through the thickening of the test of certain armored scales was observed.

Many Eucalyptus species are growing in the border of oasis areas. Eucalyptus sp. are generally known for their richness in essential oils and their virtues and economic interests. However, the great taxonomic diversity affects the quantity and quality of these oils. This study is designed to summarize the chemical composition of Eucalyptus oleosa and their biological activities. The yield of essential oils in the leaves of this species varies from 0.45% to 6.7%. These oils contain many chemical compounds of which 1,8-cineole is the main component (15.31% – 89.4%) followed by α-pinene (1%– 24.7%). Eucalyptus oleosa essential oils exhibited antioxidant, antibacterial, anti-fungal and insecticidal activities with high variability. This variability is associated to many factors such as subspecific diversity, geographical location, part of plant and essential oil’s extraction method.

Les polibenzoxazines son una classe relativament nova de resines fenòliques termoestables que posseeixen interessants propietats per a la indústria electrònica, automobilística, aerospacial i d’adhesius. Les seves possibilitats superen a les dels sistemes fenòlics clàssics, novolaques i resols, principalment en que no necessiten catalitzador per portar a terme el seu curat i no alliberen volàtils de condensació durant el mateix. Els monòmers benzoxazina es preparen habitualment per combinació de fenols i amines amb formaldehid mitjançant una condensació tipus Mannich. Aquesta química ofereix una elevada flexibilitat en el disseny estructural, fet que permet la utilització de gairebé qualsevol fenol i amina sigui comercial o sintètica. En aquesta tesi es persegueix la incorporació de derivats d’olis vegetals en monòmers i polímers precursors de polibenzoxazines per a que actuïn com a blocs flexibles. En concret, ens hem centrat en l’àcid 10-undecenoic i els seus derivats com a productes derivats de l’oli de resí, un oli vegetal no comestible. La incorporació d’aquest esquelet alifàtic, apart de d’incorporar productes derivats de fonts renovables a aquest tipus de polímers ha premés la preparació de materials flexibles. La rigidesa és una de les principals limitacions de las resines benzoxazina convencionals. Aquests objectius generals s’han aplicat a (i) monómers bis-benzoxazina sintetitzats a través de reaccions d’hidrosililació, (ii) monòmers bis-benzoxazina sintetitzats a través de reaccions d’auto-metátesi, i (iii) polímers que contenen grups benzoxazina en la cadena principal sintetitzats per polimerització de metátesi ADMET.

Los monómeros benzoxazina se preparan habitualmente por combinación de fenoles y aminas con formaldehído vía una condensación tipo Mannich.

Polybenzoxazines are a relatively new class of thermosetting phenolic resins which possess properties of interest for several technological industries such as electronic, automobile, aerospace, and adhesives. Polybenzoxazine possibilities surpass those of the classical phenolic resins, novolacs and resoles, mainly because do not require a catalyst and eliminate condensation products release problems during curing. Benzoxazine monomers are classically prepared combining phenols and amines with formaldehyde via a Mannich-type condensation. Interestingly, this chemistry offers a tremendous flexibility in structural design allowing the use of almost any commercially available or synthetic phenol or amine. This thesis pursues the incorporation of plant oil derivatives as flexible segments into polybenzoxazine monomeric and polymeric precursors. In particular, we have focused on 10-undecenoic acid and its derivatives which are valuable renewable materials derived from non-edible castor oil. The incorporation of this aliphatic skeleton of fatty acids, apart from bringing biobased character to these materials, has allowed preparing inherently tough and flexible cured systems. Inflexibility is one of the main limitations of convetional polybenzoxazine resins. These general objectives were applied to three groups of polybenzoxazine precursors: (i) bis-benzoxazine monomers obtained by hydrosilylation reaction, (ii) bis-benzoxazine monomers obtained by self-metathesis reaction, and (iii) main chain benzoxazine polymers obtained by acyclic diene metathesis polymerization.

Streszczenie:
Natural products historically represent a source of clinically approved drugs that have contributed significantly to anticancer drug development. In particular, essential oils represent a group of advantageous anticancer candidates as not only can they be produced in large quantities in a cost-effect manner but they also exhibit minimal toxicity. Melaleuca alternifolia Concentrate (MAC) is an extract prepared from the native Australian plant M. alternifolia (also a common source of Tea Tree Oil). Melaleuca oils are commonly used products, primarily utilised and investigated for their antimicrobial activity. However, over the last 2 decades, a continued stream of evidence has been produced pertaining to the anticancer potential of Melaleuca oil and its constituents. Previous studies reported Melaleuca oils to exhibit anticancer activity in vitro against a range of cancer cell lines, including melanoma, liver, leukaemia, lung, breast, and prostate cancer. However, much still remains to be discovered and elucidated about the Melaleuca oils, TTO and MAC. This thesis investigated the hypothesis that MAC represented an effective anticancer agent with immunomodulatory activity.

Streszczenie:
Interest in using renewable raw materials to prepare biobased monomers, polymers, and materials is rapidly increasing. The goal of the research described is to develop branched polyesters of plant oil fatty acids, using different core pol yo ls (i.e. sucrose, dipentaerythritol, and tripentaerythritol) and plant oils (i.e. linseed, safflower, and soybean), into curing systems that have potential uses in applications such as coatings, composites, and adhesives. This study is mainly focused on the use of sucrose as the core polyol in the soyate resins. Sucrose esters and their derivatives have a compact structure, high density, and high functionality-double bonds, epoxides, or hydroxyls. When considering the use of sucrose ester compounds to form cross linked materials, the rigid core of sucrose can potentially impart hardness to the thermoset, and the high functionality can lead to rapid gelation and high cross link density. Thus, these novel biobased resins using sucrose esters of plant oils have the potential to be a significant advance in biobased resin technology, as well as to be competitive with the conventional petroleum-based resins.

Streszczenie:
The past decade has seen an influx of speciality plant seed oils arriving into the market place. The need to characterise these oils has become an important aspect of the oil industry. The characterisation of the oils allows for the physical and chemical properties of the oil to be determined. Speciality oils were characterised based on their lipid and fatty acid profiles and categorised as monounsaturated rich (oleic acid as the major acyl components e.g. Moringa and Marula oil), linoleic acid rich (Grape seed and Evening Primrose oil) or linolenic acid rich (Flaxseed and Kiwi oil). The quality of the oils was evaluated by determining the free fatty acid content, the peroxide value (that measures initial oxidation) and p-anisidine values (that determines secondary oxidation products containing the carbonyl function). A reference database was constructed for the oils in order to compare batches of oils for their overall quality including oxidative stability. For some of the speciality oils, the stereochemistry of the triacylglycerols was determined. Calophyllum, Coffee, Poppy and Sea Buckthorn oils stereochemistry was determined. The oils were enriched with saturated and/or a monounsaturated fatty acids at position sn-1 and sn-3. The sn-2 position of the four oils was esterified with a polyunsaturated and/or a monounsaturated fatty acid indicating that they follow a typical acylation pathway and no novel acylation activity was evident from these studies (e.g enrichment of saturates at the sn-2 position). The oxidative stability of the oils was evaluated at 18oC and 60oC and the effect of adding a-tocopherol at commercially used level i.e 750ppm was assessed. The addition of 750ppm of a-tocopherol at 18oC increased the oxidative stability of Brown flax, Moringa, Wheat germ and Yangu oils. At 60oC Brown Flax, Manketti and Pomegranate oil polymerised after 48 hours. The addition of 750ppm a-tocopherol delayed the onset of polymerisation by up to 48 hours in Brown Flax seed oil. Pomegranate oil showed a high resistance to oxidation, and was blended into other speciality oils at 1%. Pomegranate oil increased the oxidative stability of Yangu oil at 18oC. The addition of Pomegranate oil to Wheat germ oil at 60oC, decreased the peroxide content by 10%. In Manketti and Brown Flaxseed oil at elevated temperatures, Pomegranate oil delayed the onset of polymerisation. Preliminary studies of Pomegranate oil blending to Moringa and Borage oil showed it to be more effective than a-tocopherol for certain oils. The antioxidant effects observed following the addition of Pomegranate oil may be due to its conjugated linolenic acid fatty acid, punicic acid.

Ocimum. micranthum Willd. à uma planta popularmente conhecida como alfavaca de folha miÃda ou estoraque sendo utilizada na medicina popular no tratamento de gripe, resfriados, febre, tosse, bronquites, nas infecÃÃes intestinais e estomacais, nas otites e como estimulante e carminativa. O presente estudo teve como objetivo mostrar a atividade do Ãleo essencial de Ocimum micranthum e seu principal constituinte, o cinamato de metila, em traquÃias isoladas de ratos Wistar. Foi evidenciado que tanto o OEOM quanto o cinamato de metila, nas concentraÃÃes de 1-1000 Âg/mL, nÃo interferem no tÃnus basal, no entanto sÃo capazes de reverter a resposta contrÃtil induzida por cloreto de potÃssio e carbacol com CI50 de 112 e 128,2 Âg/mL (para o OEOM) e 308 e 100 Âg/mL (para o cinamato de metila) respectivamente. . A concentraÃÃo de 100 Âg/mL OEOM, quando adicionada antes do agente contrÃtil, à capaz de atenuar a resposta mÃxima do KCl em traquÃias de ratos naÃve, fato que nÃo ocorreu quando a contraÃÃo foi induzida por carbacol na presenÃa de nitrendipina. Adicionalmente, em animais submetidos a modelos de asma pela OVA, o OEOM se mostrou mais ativo em animais desafiados do que apenas sensibilizados. Portanto, o mecanismo envolvido nos efeitos miorrelaxante e antiespasmÃdico do OEOM Ã, pelo menos em parte, devido à sua aÃÃo preferencial nos canais de cÃlcio operados por voltagem (VOCC). Seu principal constituinte, o cinamato de metila, parece estar envolvido nos efeitos miorrelaxantes do OEOM.
The Ocimum. micranthum Willd. is a plant popularly known as âalfavaca-de-folha-miÃdaâ or âestoraqueâ and is used in folk medicine to treat flu, colds, fever, cough, bronchitis, stomach and intestinal infections, ear infections and as stimulant and carminative. This study aimed to show the activity of its essential oil (EOOM) and of its main constituent, methyl cinnamate, in rat isolated trachea. It was shown that both the OEOM and methyl cinnamate (1-1000 Âg/mL) did not change the basal tone, but they were able to reverse the contractile response induced by potassium chloride or carbachol with IC50 of 112 and 128.2 Âg/mL (for EOOM) and 308 and 100 μg/mL (for methyl cinnamate), respectively. At 100 Âg/mL, added before the contractile agent, EOOM attenuated maximal response to KCl in trachea from naÃve rats. This effect did not occur when contraction was induced by carbachol in the presence of nitrendipine. Additionally, in animals subjected to an ovalbumin-sensitized model of asthma, EOOM was more active in challenged than in sensitized animals. In conclusion,th e myorelaxant and antispasmodic effects of the EOOM are due to its preferential action on voltage-operated calcium channels. Its major constituent, methyl cinnamte, appears to be involved in the pharmacological effects of the EOOM.

The lubricating properties of vegetable oil are well known. However, with the advent of petroleum oils, castor oil and other vegetable oils fell out of favor. The quality of petroleum oils has improved significantly in the last few years with the introduction of Group III base oils. However, even Group III oils fall short of the inherent lubricity of vegetable oils. Analogous to advances in petroleum oils, improvement of vegetable oils by genetic modification to obtain high oleic oils has led to better acceptance of these oils as lubricants. Studies have shown significant reduction in tail pipe emissions when using these types of oils in an engine crank case. We have successfully expressed a hydroxylase gene in a high oleic canola variety. The combination of a high oleic background and hydroxy fatty acids produced an oil with properties that improve further on high oleic oils. The presence of the hydroxy group provides improved lubricity. This technology will allow us to create oils with varying hydroxy fatty acid content depending on the application. These applications can range from use in lubricants, as chemical feedstocks, and reactive components in polymers.

Most traditional fats for the food industry take hydrogenated oils and high saturated oils as the base material. However, hydrogenated oils and high saturated oils were widely questioned because of the threat to health caused by trans and saturated fatty acids. Oleogelation is a potential strategy to structure liquid oils to replace traditional fats in foods. The aerogel-templated method allowed plant-derived polymers (polysaccharides and proteins) to prepare oleogels. Methyl-cellulose and xanthan gum were dissolved in waters and aerated to prepare aqueous foams. The molecular network of polysaccharides in aqueous foams was rapidly fixed by the ultra-low temperature freezing method, and aerogels were obtained by freeze-drying. The ultra-low temperature freezing method made aerogels have an average pore size of 36.7 μm and improved the porosity. Because of the open network in aerogels, there was a gap between oleogels fabricated by aerogels and traditional fats. Hence, fat crystals were used to further enhance the network structure in oleogels. Vegetable fats (Palm oil, coconut oil, palm kernel oil, and palm kernel stearin) were used to replace 50% of the soybean oil to enhance oleogels made by the aerogel-templated method. Aerogels had stronger oil absorption ability for oils containing PKS and PKO, reaching 39.6 and 38.24 g/g, respectively. Enhancement effects of different vegetable fats on oleogels were analyzed by the oil binding ability, polarized light microscopy, and rheological test. The crystal network formed by coarse crystals could endow oleogels with higher oil binding ability and more robust solid properties but result in more sensitivity to temperature. Through FTIR analysis, the hydrogen bond between polysaccharides constituting the polymer network was detected. The addition of vegetable fats could make oleogels physical properties of traditional fats, thus making oleogels further in the traditional fat replacement.

Objectives: The Israeli work plan regarding HBTM included: (a) producing a better diagnostic method; (b) following infestations during the season and evaluating damage to resistant bees and, (c) controlling HBTM by conventional means under local conditions. For varroa our plans to try novel control (e.g. oil novel control (e.g. oil patties & essential oils) were initially delayed by very low pest populations, then disrupted by the emergence of fluvalinate resistance. We monitored the spread of resistance to understand it better, and analyzed an underlying biochemical resistance mechanism in varroa. The US work plan focused on novel management methods for both mites with an emphasis on reducing use of traditional insecticides due to resistance and contamination issues. Objectives were: (a) evaluating plant essential oils for varroa control; (b) exploring the vulnerability of varroa to desiccation for their management; and (c) looking for biological variation in HBTM that could explain virulence variability between colonies. Although the initial PI at the USDA Beltsville Bee Lab, W.A. Bruce, retired during the project we made significant strides especially on varroa water balance. Subcontracts were performed by Yoder (Illinois College) on varroa water balance and DeGrandi-Hoffman (USDA) who evaluated plant essential oils for their potential to control varroa. We devised an IPM strategy for mite control i the U.S. Background: Mites that parasitize honey bees are a global problem. They are threatening the survival of managed and feral bees, the well-being of commercial/hobby beekeeping, and due to pollination, the future of some agricultural commodities is threatened. Specific economic consequences of these mites are that: (a) apiculture/breeder business are failing; (b) fewer colonies exist; (c) demand and cost for hive leasing are growing; (d) incidences of bee pathogens are increasing; and, (e) there are ore problems with commercial-reared bees. As a reflection of the continued significance f bee mites, a mite book is now in press (Webster & delaplane, 2000); and the 2nd International Conference on Africanized Honey Bees and Bee Mites is scheduled (April, 2000, Arizona). The first such conference was at OSU (1987, GRN was co-organizer). The major challenge is controlling two very different mites within a colony while not adversely impacting the hive. Colony management practices vary, as do the laws dictating acaricide use. Our basic postulates were that: (a) both mites are of economic importance with moderate to high infestations but not at low rates and, (b) once established they will not be eradicated. A novel strategy was devised that deals with the pests concomitantly by maintaining populations at low levels, without unnecessary recourse to synthetic acaricides. Major Conclusions, Solutions, Achievements: A major recent revelation is that there are several species of "Varroa jacobsoni" (Anderson & Trueman 1999). Work on control, resistance, population dynamics, and virulence awaits knowing whether this is a problem. In the U.S. there was no difference between varroa from three locales in terms of water balance parameters (AZ, MN & PA), which bodes well for our work to date. Winter varroa (U.S.) were more prone to desiccation than during other seasons. Varroa sensitivity to desiccation has important implications for improving IPM. Several botanicals showed some promise for varroa control (thymol & origanum). Unfortunately there is varroa resistance to Apistan in Israel but a resistance mechanism was detected for the first time. The Israel team also has a new method for HBTM diagnosis. Annual tracheal mite population trends in Israel were characterized, which will help in targeting treatment. Effects of HBTM on honey yields were shown. HBTM control by Amitraz was demonstrated for at least 6 months. Showing partial resistance by Buckfast bees to HBTM will be an important IPM tactic in Israel and U.S.

Streszczenie:
The FAO has projected a doubling in world demand for seafood during the 21 ed from aquaculture of marine fish and shrimps fed primarily on fishmeal-based aquafeeds. However, current practices of high intensity monoculture of shrimp in coastal ponds and fish in offshore pens have been strongly criticized as being ecologically and socially unsustainable. This view derives from un- checked eutrophication of coastal marine ecosystems from fish farm effluents, and the destruction of coastal estuarine ecosystems by shrimp farm constructions, plus aquaculture’s reliance on wild-caught small fish - which are excellent food for humans, but instead are rendered into fishmeal and fish oil for formulating aquafeeds. Fishmeal-sparing and waste- reduction aquafeeds can only delay the time when fed aquaculture product are priced out of affordability for most consumers. Additionally, replacement of fishmeal protein and fish oil by terrestrial plant sources such as soybean meal and oil directly raises food costs for human communities in developing nations. New formulations incorporating sustainably-produced marine algal proteins and oils are growing in acceptance as viable and practical alternatives. This BARD collaborative research project investigated a sustainable water-sparing spray/drip culture method for producing high-protein marine macrophyte meals for incorporation into marine shrimp and fish diets. The spray culture work was conducted at laboratory-scale in the USA (UCSD-SIO) using selected Gracilariaand Ulvastrains isolated and supplied by UCONN, and outdoors at pilot-scale in Israel (IOLR-NCM) using local strains of Ulvasp., and nitrogen/phosphorus-enriched fish farm effluent to fertilize the spray cultures and produce seaweed biomass and meals containing up to 27% raw protein (dry weight content). Auburn University (USA) in consultation with TAMUS (USA) used the IOLR meals to formulate diets and conduct marine shrimp feeding trials, which resulted in mixed outcomes, indicating further work was needed to chemically identify and remove anti-nutritional elements present in the IOLR-produced seaweed meals.

At least ten Latin American and Caribbean countries have pledged to achieve carbon neutrality. Has electricity planning in the region evolved towards reaching these goals? We compare power generation capacity in 2023 to announced plans in 2019. We then estimate committed emissions from existing and planned power plants that is emissions that would result from the normal operations of these plants during their typical lifetime and compare them to emissions from power generation in published IPCC scenarios. We find that fossil fuel planned capacity has decreased by 47% since 2019, mainly due to the cancellation of 50% of coal and 40% of gas projects, compared to only 32% of renewable energy projects. But existing plants in the region will emit 6.7 GtCO2 during their lifespan, and if all planned plants are built, they will add 4.9 GtCO2, totaling 11.6 GtCO2, exceeding median carbon budgets for 1.5 and 2C-consistent IPCC pathways (2.3 and 4.3 GtCO2). Natural gas power plants are the largest contributor to existing (62%) and planned (75%) emissions (versus 24% and 23% for coal). We evaluate emissions reduction strategies to achieve carbon budgets. Assuming no new coal plants comes into operation, announced gas and oil projects are canceled at the same rate as in the past four years, all fossil fueled plant lifetimes are reduced by 10 years, and all new natural gas displaces existing coal, committed emissions fall by 59%, almost meeting the 2C budget, but still twice as large as the median 1.5C budget. Our results suggest that while progress is being made, energy planning in the region is not yet consistent with global climate goals as reflected by the IPCC scenario database.

Abstract Mitochondria are the site of respiration and numerous other metabolic processes required for plant growth and development. Increased demands for metabolic energy are observed during different stages in the plants life cycle, but are particularly ample during germination and reproductive organ development. These activities are dependent upon the tight regulation of the expression and accumulation of various organellar proteins. Plant mitochondria contain their own genomes (mtDNA), which encode for rRNAs, tRNAs and some mitochondrial proteins. Although all mitochondria have probably evolved from a common alpha-proteobacterial ancestor, notable genomic reorganizations have occurred in the mtDNAs of different eukaryotic lineages. Plant mtDNAs are notably larger and more variable in size (ranging from 70~11,000 kbp in size) than the mrDNAs in higher animals (16~19 kbp). Another unique feature of plant mitochondria includes the presence of both circular and linear DNA fragments, which undergo intra- and intermolecular recombination. DNA-seq data indicate that such recombination events result with diverged mitochondrial genome configurations, even within a single plant species. One common plant phenotype that emerges as a consequence of altered mtDNA configuration is cytoplasmic male sterility CMS (i.e. reduced production of functional pollen). The maternally-inherited male sterility phenotype is highly valuable agriculturally. CMS forces the production of F1 hybrids, particularly in predominantly self-pollinating crops, resulting in enhanced crop growth and productivity through heterosis (i.e. hybrid vigor or outbreeding enhancement). CMS lines have been implemented in some cereal and vegetables, but most crops still lack a CMS system. This work focuses on the analysis of the molecular basis of CMS. We also aim to induce nuclear or organellar induced male-sterility in plants, and to develop a novel approach for fertility restoration. Our work focuses on Brassicaceae, a large family of flowering plants that includes Arabidopsis thaliana, a key model organism in plant sciences, as well as many crops of major economic importance (e.g., broccoli, cauliflower, cabbage, and various seeds for oil production). In spite of the genomic rearrangements in the mtDNAs of plants, the number of genes and the coding sequences are conserved among different mtDNAs in angiosperms (i.e. ~60 genes encoding different tRNAs, rRNAs, ribosomal proteins and subunits of the respiratory system). Yet, in addition to the known genes, plant mtDNAs also harbor numerous ORFs, most of which are not conserved among species and are currently of unknown function. Remarkably, and relevant to our study, CMS in plants is primarily associated with the expression of novel chimericORFs, which likely derive from recombination events within the mtDNAs. Whereas the CMS loci are localized to the mtDNAs, the factors that restore fertility (Rfs) are identified as nuclear-encoded RNA-binding proteins. Interestingly, nearly all of the Rf’s are identified as pentatricopeptide repeat (PPR) proteins, a large family of modular RNA-binding proteins that mediate several aspects of gene expression primarily in plant organelles. In this project we proposed to develop a system to test the ability of mtORFs in plants, which are closely related to known CMS factors. We will induce male fertility in various species of Brassicaceae, and test whether a down-relation in the expression of the recombinantCMS-genes restores fertility, using synthetically designed PPR proteins.
