Streszczenie:

In today's world of rapidly changing climates, ever-increasing human population growth and increased competition for space, the production of energy and high quality food to meet increasing demands presents an enormous challenge to the related industries. It has been predicted that global food production alone, must increase by 70% by 2050 to prevent worldwide starvation. The application of plant biotechnology offers a promising alternative over classical crop improvement techniques in the development of breeding programmes that could respond rapidly to future demands for high-yielding and nutritionally-enhanced crops. Adopting such strategies to underutilised legume crops represents a viable avenue for crop improvement, especially in developing countries with a high incidence of poverty and malnutrition, where local environmental conditions frequently prove too challenging for effective cultivation of commercial cultivars. The main objective of this thesis was to generate fundamental data regarding the adoption of tissue culture-based transformation strategies for the genetic improvement of two such crops, jicama [Pachyrhizus erosus (L.) Urban] and Bambara groundnut [Vigna subterranea (L.) Verdc.]. The work carried out on jicama investigated the regeneration potential of this plant in vitro as a basis for future biotechnological techniques. Preliminary tissue culture experiments identified explant types and plant growth regulator (PGR) matrices and concentrations that produced optimal regenerative responses in vitro. Histological analysis of regenerated tissue revealed that shoot formation occurred via somatic embryogenesis. Possible avenues for further optimisation of the explant-to-plant regeneration protocol, for downstream molecular genetic applications, were explored and discussed. For Bambara groundnut, this study initially focused on developing a novel explant-to-plant regeneration system, previously not reported for landraces DipC, Uniswa-Red and S 19-3, through the adoption and modification of techniques specific for distinct Bambara landraces. This micropropagation protocol employed whole zygotic embryos as starting explants, which formed the basis for subsequent transformation studies. Genetic transformation was attempted via biolistic- and Agrobacterium-mediated approaches, using transformation vectors pVDH65, pB1l21, harbouring the nptII selectable marker and uidA (gus) reporter genes, while pBIl21-LeB4-Ber e I additionally carried the methionine-rich ber el gene. T-DNA transfer in transformed explants was confirmed via histochemical GUS analyses, while peR assays identified putatively transformed regenerated shoots. Explant viability was significantly compromised following bombardment or inoculation, resulting in reduced shoot regeneration, and thus limited the production of transgenic plants. Improvements in transformation efficiency and regeneration frequency were made following protocol optimisation, and the potential for further improvements to efficiently produce well-developed, healthy transgenic shoots were explored and discussed. The results presented in this thesis describe the optimisation of innovative tissue culture and regeneration protocols, which form a fundamental prerequisite to future transformation-based experiments for jicama and Bambara groundnut. Additionally, previously unpublished data generated from transformation studies in Bambara groundnut has revealed its potential for genetic manipulation. These results have established the foundation of novel micropropagation and transformation systems with the potential to be further optimised to genetically enhance and exploit the enormous agronomic potential of these underutilised legume crops.

Streszczenie:

Les Légumineuses ont développé une interaction symbiotique avec des bactéries du sol, les rhizobia, qui fixent l’azote atmosphérique et le transfèrent à la plante sous forme assimilable.Cette interaction a lieu, au sein des nodosités, des organes racinaires où les bactéries intracellulaires se différencient en bactéroïdes. Chez Medicago truncatula, ces bactéroïdes correspondent à un stade de différentiation terminale corrélée à une endoréplication de leur génome, une augmentation de la taille des cellules, une modification des membranes et une faible capacité à se propager. Cette différentiation est induite par des facteurs de la plante appelés NCR (Nodule-specific Cysteine Rich). Les peptides NCRs ressemblent à des défensines, des peptides antimicrobiens ayant une activité antimicrobienne in vitro, tuant des bactéries. Ainsi, un élément clef dans la différenciation des bactéroïdes est la protéine bactérienne BacA, un transporteur membranaire qui confère une résistance contre l’activité antimicrobienne des peptides. Dans le cadre de ce travail de thèse, j’ai montré que l'expression des NCR est soumise à une régulation stricte et qu’ils sont activés dans trois vagues dans les cellules symbiotiques polyploïdes.Les mécanismes de contrôle par la plante sur les rhizobia intracellulaires demeurent à ce jourpeu connus et le seul modèle étudié, au début de ce travail de thèse, restait l'interaction entre M. truncatula et S. meliloti. Je me suis donc intéressée à la symbiose de certaines Légumineuses tropicales du genre Aeschynomene appartenant au clade des Dalbergoïdes où jemontre qu’ils utilisent une classe différente de peptides riches en cystéine (NCR-like) pour induire la différenciation des bactéroïdes. Ce mécanisme est analogue à celui décrit précédemment chez Medicago qui était jusqu'à présent supposé être limitée aux légumineuses appartenant au clade des IRLC. J’ai également montré que Bradyrhizobium, symbionte d’Aeschynomene possèdent un transporteur de type ABC homologues à BacA de Sinorhizobium nommé BclA. Ce gène permet l'importation d'une variété de peptides comprenant des peptides NCR. En l'absence de ce transporteur, les rhizobiums sont incapables de se différencier et de fixer l'azote.Cette étude a permis d'élargir nos connaissances sur l'évolution de la symbiose en montrant qu’au cours de l’évolution, deux clades de Légumineuses relativement éloignés (IRLC et Dalbergoïdes) aient convergé vers l’utilisation de peptides de l’immunité innée afin de contrôler leur symbionte bactérien et d’en tirer un bénéfice maximal au cours de l’interaction symbiotique
The ability of legumes to acquire sufficient nitrogen from the symbiosis with Rhizobium relies on the intimate contact between the endosymbiotic, intracellular rhizobia, called bacteroids, and their host cells, the symbiotic nodule cells. A well-studied example is the symbiotic nitrogen fixing bacterium Sinorhizobium meliloti, which nodulates the legume Medicago truncatula. Nodules of M. truncatula produce an enormous diversity of peptides called NCRs which are similar to antimicrobial peptides (AMPs) of innate immune systems. These NCRs are involved in maintaining the homeostasis between the host cells in the nodules and the large bacterial population they contain. Although many NCRs are genuine AMPs which kill microbes in vitro, in nodule cells they do not kill the bacteria but induce them into the terminally differentiated bacteroid state involving cell elongation, genome amplification, membrane fragilization and loss of cell division capacity. Protection against the antimicrobial action of NCRs by the bacterial BacA protein is critical for bacteroid survival in the symbiotic cells and thus for symbiosis. As a part of my PhD thesis, I have shown that the differentiation of the symbiotic cells in M. truncatula is associated with a tremendous transcriptional reprogramming involving hundreds of genes, mainly NCR genes, which are only expressed in these cells. Although the extensive work on the model M. truncatula/S. meliloti, little is known how the plant controls its intracellular population and imposes its differentiation into a functional form, the bacteroids in other symbiotic systems.In my PhD work, I provide several independent pieces of evidence to show that tropical legumes of the Aeschynomene genus which belong to the Dalbergoid legume clade use a different class of cysteine rich peptides (NCR-like) to govern bacteroid differentiation. This mechanism is similar to the one previously described in Medicago which was up to now assumed to be restricted to the advanced IRLC legume clade, to which it belongs. I have also shown that the Bradyrhizobium symbionts of Aeschynomene legumes possess a multidrug transporter, named BclA, which mediates the import of a diversity of peptides including NCR peptides. In the absence of this transporter, the rhizobia do not differentiate and do not fix nitrogen. BclA has a transmembrane domain of the same family as the transmembrane domain of the BacA transporter of Rhizobium and Sinorhizobium species which is known to be required in these rhizobia to respond to the NCR peptides of IRLC legumes. Again this is a mechanism which is analogous to the one described in S. meliloti the symbiont of Medicago.This study broaden our knowledge on the evolution of symbiosis by showing that the modus operandi involving peptides derived from innate immunity used by some legumes to keep their intracellular bacterial population under control is more widespread and ancient than previously thought and has been invented by evolution several times

Dalea is a member of the family Leguminosae which includes many commonly cultivated plants used in southwestern desert landscapes. With 166 described species, it is surprising to learn that until recently Dalea has largely been neglected horticulturally. In this paper I discuss seven promising species that have been tested in landscape situations for five years. These include six shrubs and one spreading groundcover. All except the groundcover are extremely showy when at the peak of flowering. Each species is unique and all are highly recommended for landscaping in arid regions of the world.

Streszczenie:

Studies were conducted to test germination and to determine morphological and physiological characteristics of Canavalia obtusifolia DC., Cratylia floribunda Benth. and Dioclea lasiophylla Mart., which allow them to cope with water stress. Germination studies were done using PEG, moist paper and three different soils, in a germinator. Establishment and early growth studies were conducted in a greenhouse, using two different soils. In PEG, maximum percentage germination were near 100% for C. obtusifolia and D. lasiophylla and 75% for C. floribunda. Respectively, the water potentials for maximum germination were from 0 to -1 bar, from 0 to -5 bars, and at -5 bars. In moist paper, however, C. floribunda had near 100% germination. In the three soils, the three species had near or equal to 100% germination and their radicle grew more than in PEG. The rate of germination tended to be faster in soil than in PEG. However, it was affected by both soil and seed characteristics. So, germination was slower in Canelo, a pH 4, clay soil, as well as for the large-seeded C. obtusifolia, may be due to the reduction in the soil water conductivity at the seed-soil interface. It is suggested that leakage of solutes and spoilage of seeds as well as rapid water uptake at high water potentials, resulted in low germination of C. floribunda in PEG. Plants of C. floribunda and D. lasiophylla did not decrease their stomatal conductance or transpiration under high water stress, and their leaf water and osmotic potentials were sharply reduced. Plants of C. obtusifolia partially decreased their stomatal conductance and transpiration under stress. All three species were able to withstand elevated dehydration and to recover after being exposed to leaf water potentials lower than -60 bars. C. obtusifolia maintained net CO₂ assimilation at a high dehydration level (-46.1 bars). After rewetting, this species rapidly recovered its leaf water potential and turgor; its photosynthetic capacity, however, was not totally recovered after being rewetted for six days.

Streszczenie:

The occurrence of 3-nitropropionic acid (3NPA) was measured in 80 legume species. 3 NPA was detected in 19 species, 6 of which have not been recorded previously as containing 3NPA. 3NPA oxidase was detected in 15 of these species, but not in Astragalus hamosus, Astragalus excapus and Astragalus massiliensis. The enzyme was not detected in species which do not accumulate 3NPA. Annual variation in 3NPA levels was detected in field populations of Hippocrepis comosa, with levels significantly higher from April to September. 3NPA was also detected in Hippocrepis comosa leaves in field populations from 16 vice-counties in Britain. The following experiments produced evidence of nitrification in legumes that accumulate 3NPA, 3NPA, nitrite and nitrate were found in the leaves of Hippocrepis comosa, Coronilla viminalis and Securigera securidaca grown in water culture with reduced nitrogen. Significantly more oxidised nitrogen was found in Hippocrepis comosa and Securigera securidaca grown in sterile agar with ammonium than is present in the seed. Nodulated Hippocrepis comosa plants grown in perlite without added nitrogen contained nitrite, nitrate and 3NPA. Higher levels of 3NPA, nitrite and nitrate were measured in soil collected from under Hippocrepis comosa plants than in soil sampled from under a control species, suggesting that the deposition of Hippocrepis comosa litter may have a significant effect on the nitrogen content of the soil. Further characterisation of 3NPA oxidase was carried out. The flavin component was identified as FMN, with 1 molecule FMN per subunit. The stoichiometry of the reaction is complex and non-integral in the consumption of oxygen, with a role suggested for hydrogen peroxide and superoxide.

Abstract Although nodulated legumes have been used by indigenous peoples in Africa for centuries, their full potential has never been realized. With modern technology there is scope for rapid improvement of both plant and microbial germplasm. This review gives examples of some recent developments in the form of case studies; these range from multipurpose human food crops, such as cowpea (Vigna unguiculata (L.) Walp.), through to beverages (teas) that are also income-generating such as rooibos (Aspalathus linearis (Burm. f.) R. Dahlgren, honeybush (Cyclopia Vent. spp.), and the widely used food additive gum arabic (Acacia senegal (L.) Willd.). These and other potential crops are welladapted to the many different soil and climatic conditions of Africa, in particular, drought and low nutrients. All can nodulate and fix nitrogen, with varying degrees of effectiveness and using a range of bacterial symbionts. The further development of these and other species is essential, not only for African use, but also to retain the agricultural diversity that is essential for a changing world that is being increasingly dominated by a few crops such as soybean.

Streszczenie:

Legumes underpin the global food network, providing the majority of the world’s dietary protein. However, global productivity of grain legumes is limited by environmental stresses, particularly chilling and freezing. For example, chilling temperatures (0-15 ºC) limit the production of soybean (Glycine max; a tropical legume), while extreme freezing temperatures (< 0 ºC) limit use of temperate legumes such as faba bean (Vicia faba L). The following studies were performed to gain new insights into chilling and freezing tolerance in these two important legumes. Transgenic soybean lines, overexpressing the rice cysteine protease inhibitor, oryzacystatin I (OCI), showed decreased chillinginduced inhibition of photosynthesis compared to wild type (Wt). These lines also showed an increased abundance of transcripts encoding the strigolactone (SL) biosynthesis enzymes: carotenoid cleavage dioxygenases 7 and 8 (CCD7, CCD8). Pea (rms3, rms4, rms5) and Arabidopsis thaliana (max2-1, max3-9, max4-1) mutants, deficient in SL synthesis and signalling, showed enhanced sensitivity to dark-chilling. Differences in chilling and freezing sensitivity were also identified in 5 faba bean cultivars. Transcriptome profiling comparisons were performed on the most chilling sensitive (Wizard) and most chilling tolerant (Hiverna) cultivars to identify specific differences in gene expression, underpinning stress tolerance. Moreover, genome sequencing of the Wizard cultivar enabled the assembly and annotation of the mitochondrial and chloroplast genomes. Single nucleotide polymorphisms (SNP) were found in several organelle genes, when comparing read sequences to published references. Furthermore, based on published SNP orientated linkage maps, contiguous read sequences could be mapped to chromosomal loci, leading to the identification of 8 putative nuclear gene sequences and an increase in sequence length data at 147 loci. Together with these new genomic resources, the discovery that cysteine proteases, phytocystatins and SL are important in legume low temperature tolerance will enable the development of stress tolerance markers, for use in faba bean selective breeding programs.

As tendências de estilo de vida da população causaram mudanças nos hábitos alimentares em todo o planeta e a necessidade de redução do tempo de preparo de alimentos. Isso tem contribuído para o aumento nas vendas de produtos em porções únicas e de refeições rápidas. No processo de produção, as refeições rápidas devem ser imediatamente resfriadas ao final do processo de cozimento, com o propósito de melhorar a segurança alimentar, reduzindo o desenvolvimento microbiano. O resfriamento a vácuo tem sido apontado como uma alternativa viável para o resfriamento rápido de alguns produtos alimentícios. O objetivo deste trabalho foi investigar a possibilidade de integrar os processos de cozimento e de resfriamento de batatas e cenouras em um só equipamento, através do uso do resfriamento a vácuo. Estudou-se a influência de diferentes tempos e temperaturas de cozimento, diferentes métodos de cozimento (cozimento a vapor e imersão em água em ebulição) e resfriamento (a vácuo e em câmara fria, com e sem imersão em água) na perda ou ganho de massa e na textura do produto final. Os resultados indicaram que a perda de massa durante a etapa de resfriamento foi dependente do tempo e da temperatura de cozimento, assim como do processo de resfriamento. O tempo e a temperatura de cozimento influenciaram significativamente a textura dos vegetais, reduzindo a firmeza dos mesmos. Observou-se também que os parâmetros de textura de amostras de batatas e cenouras resfriadas a vácuo e em câmara fria foram dependentes do conteúdo de umidade final. Para um mesmo tempo de cozimento, quanto maior o teor de umidade final das amostras resfriadas, maiores foram os valores da força de compressão para uma mesma deformação relativa, da dureza, gomosidade e mastigabilidade resultantes das análises de TPA. Os parâmetros adesividade, coesividade e elasticidade das amostras não foram diferentes, ao nível de significância de 5%. Desta forma, o uso da técnica de resfriamento a vácuo integrado ao cozimento de legumes é uma alternativa para processamento industrial desses alimentos. Com esse procedimento, pode-se reduzir o tempo de resfriamento e de processamento e evitar o contato do produto com água de resfriamento, reduzindo o risco de contaminações cruzadas.
Changes on global life style have led to changes on food preparation and consumption. These changes have been increasing sales of products in single servings and ready meals. During ready meals industrial production, they must be immediately cooled after cooking, to prevent or reduce microbial growth. Vacuum cooling has been reported as a viable alternative to the rapid cooling of some food products. The aim of this work was to investigate the possibility of integrating food cooking and cooling of potatoes and carrots in single equipment, by the use of vacuum cooling. It was investigated the influence of different cooking times and temperatures, different methods of cooking (steam and immersion in boiling water) and cooling (vacuum cooling and cold room cooling) in the weight loss or weight gain, and on the texture of the final product. The results indicated that the weight loss during cooling was dependent of the time and of the cooking temperature, as well as of the process cooling (vacuum cooling and cold room cooling). Texture parameters of potatoes and carrots samples, cooled by vacuum or in the cold room, were dependent of the final moisture contents. Time and temperature of cooking influenced the vegetable texture, reducing their hardness. It was also observed that the increase of the final moisture content resulted in an increase of compression force for a given strain, hardness, gumminess and chewiness, resulting from TPA tests. The TPA parameters adhesiveness, springiness and cohesiveness did not show differences at 5% of significance level. Thus, the integration of cooking and vacuum cooling of potatoes and carrots in a same vessel can be a viable alternative for industrial processing. With this procedure, it is possible to reduce cooling and process times and to avoid contact between cooked product and cooling water, reducing risk of cross contamination.

Streszczenie:

[Truncated abstract] Faba bean (Vicia Faba L.) ranks third worldwide in overall production among coolseason legume crops and is used as a main source of protein both for food and feed purposes in many parts of the world. Australia is a major exporter of faba beans and the price received depends on the quality of the seed especially colour of the seed coat. Consumers don?t like faba beans that are dark coloured or that have blemishes on the seed coat. Environmental staining and storage discolouration deteriorate seed colour causing substantial economic losses to growers and grain handlers. To investigate the influence of environmental conditions, especially during pod/seed development and maturity, on the degree of environmental staining, field trials were conducted using four faba bean varieties (Fiord, Fiesta, Ascot and Cairo) in a range of environmental conditions under the Mediterranean-type climate of south western Australian grain belt. Although a majority of seeds had good colour but 3-25% were stained up to an unacceptable level across the trials and this varied with location and variety. Seeds formed later in plant development (located on the upper nodes of the plant) were more stained than seeds formed earlier (located on the lower nodes). This may be due to end of season environmental factors, such as high temperature and light intensity, and water and nutrient stress. Similarly seeds formed on small and weak plants, which may have developed under stressful conditions, had more staining than seeds formed on normal sized and healthy plants. Genotypic variation was also evident with Fiord showing greater staining than Ascot, Fiesta and Cairo. The cause of environmental staining appears to be complex but was associated with phenolic contents. Storage discolouration was influenced by a number of factors including temperature, seed moisture content, light and storage period and these were critical in determining storage life. ... Faba bean hardness, examined by the hard-to-cook test, also increased with increased storage temperature. There was a high negative correlation (r2 = 0.98) between storage temperature and cooking ability of faba bean. There was a three-fold increase in lignin content of faba bean stored at 50°C compared to those stored at 5°C and it was correlated with bean hardness (r2 = 0.98). Reduction in free phenolics was negatively correlated (r2 = 0.75) with bean hardness. The environmental staining in faba bean can be minimized with correct choice of varieties, robust agronomic practices to establish and maintain healthy plants and the use of mechanical graders and colour sorters. For minimizing storage discolouration faba beans must be dehydrated to ≤12% seed moisture content and stored in insulated bins (silos) or at least bins painted white and constructed under trees shades. In addition occasional flushing with N2 will further help reduce the colour darkening. The above approaches will improve quality, market opportunities, price and hence profitability of faba bean in the farming systems.

Streszczenie:

Mesophyll conductance (gm) limits the diffusion of CO2 from sub-stomatal cavities to the carboxylation site and is a significant limitation to photosynthesis. However, there is a lack of complete understanding of gm variability and its regulation under different environmental conditions, and relevant studies in grain legumes are scarce. My research projects aimed to characterize genetic variability in gm, to quantify the response of gm to short- and long-term environmental changes and to assess the relationship of gm with leaf water-use efficiency (WUE) in grain legumes. gm and leaf hydraulic conductance (Kleaf) were examined simultaneously under growth conditions to see if they show coordinated response. gm varied significantly among genotypes for most of the legumes studied, but the genotypes did not vary in cell wall and plasma membrane conductance (measured from the oxygen isotope method). gm responded to growth or measurement environments, increasing rapidly with increasing light intensity but decreasing under blue light. However, genotypes differed in their interactive response to water stress, light intensity and light quality. Rapid response of gm to changes in light intensity was affected by N source (N2-fixing or inorganic-N fed). Short-term temperature response of gm varied between species. Chloroplast membrane conductance varied among species and genotypes and with growth environment. Environmentally driven leaf anatomical traits were not the major factors determining gm, but genotypes differed in the degree to which leaf anatomy influenced gm. Our results did not show coordination between gm and Kleaf. gm was strongly associated with photosynthetic rate but not with stomatal conductance. The results of this project provide useful information for crop genetic improvement through gm in legumes under climate change scenarios. Increasing gm in legumes will increase photosynthetic rate and possibly WUE, when there is no increase in stomatal conductance.

Streszczenie:

The present study consists of a taxonomic revision of the New World species of Sesbania (Papilionoideae, Robinieae) and taxonomic studies on the unifoliolate species of Lupinus (Papilionoideae, Genisteae) in Brazil. The genus Sesbania in the New World is here recognised as comprised of the subgenera Sesbania (with three native and three introduced species), Daubentonia (with five species) and Agati (one species, introduced). As part of the taxonomic revision of Sesbania, a survey on chromosome number and studies on pollen and seed morphology are presented. In an outline treatment of the genus Lupinus in Brazil the problems associated with the ca. 16 multifoliolate species are reviewed. The unifoliolate species have been studied in detail and 13 species are recognised. A taxonomic account of the unifoliolate species with key, descriptions and illustrations and specimen citations is presented. A SEM survey of pollen grains and testa of Lupinus, with particular emphasis on the Brazilian unifoliolate species accompanies this study.

This study records all known legume (Leguminosae/Fabaceae) species indigenous to South Africa, Lesotho and Swaziland to establish distribution patterns and optimum climatic and soil conditions for growth. The main purpose was to propose a list of legume species for further evaluation of their pasture potential. Collection data supplied by the National Herbarium (PRE) Computerised Information System were recorded to establish the distribution patterns of species based on the bioregions vegetation map. A total of 1 654 species are known to be indigenous, representing 24 tribes and 122 genera. The grouping of legume species into five main clusters and 16 Leguminochoria is ecologically described, with the highest legume species richness found in the Northern Mistbelt Forest. Key and diagnostic species are provided for each Leguminochorion. Soil pH and mean annual minimum temperature were found to be the main drivers for distinguishing between legume assemblages. The optimum climatic and soil conditions for growth are described as well as the available descriptive attributes for species recorded. Information on the range of tolerance of most species to abiotic factors is presented. Mean annual rainfall and soil pH are highly correlated with the distribution pattern of most species, followed by mean annual minimum temperature. Legume species adapted to a wide range of soil pH levels and low soil phosphorus levels are recorded. Existing data on the cultivation and grazing or browsing status of indigenous legumes were used to select 584 species found mainly in the Central Bushveld, Mopane and Lowveld Bioregions to be further evaluated for their pasture potential. Known characteristics were used to categorise species. Species contained in the tribe Phaseoleae are of special interest since it contains most of the genera with present-day agricultural value, i.e. Eriosema, Rhynchosia and Vigna species are listed as having high potential as pasture species. This study has shown that the descriptive and distribution data accumulated by botanists (notably taxonomists) could be of beneficial use in meeting agricultural objectives. Indigenous legumes are adapted to a wide range of soil and climatic conditions and represent a valuable but largely unexploited natural resource for pasture development and soil conservation practices.

With the objective to determine guinea pig digestibility of the nutritive components of Vicia villosa, red clover, and Lolium multiflorum in relation to alfalfa, the digestibility coefficients were evaluated for fiber, protein, dry matter, energy, and dry matter consumption in these three species in a completely random block design with four repetitions. The results showed that for alfalfa digestibility coefficients of 85.7% of the protein and 2806.6 kcal/kg of digestible energy, plus an economic substitution value (ESV) of fiber, protein, and energy of US$0.41 and $0.38/kg and US$0.009/1000 kcal, respectively. Lolium multiflorum had the highest tendency toward digestibility with 60.7% of fiber and the highest consumption with 81.3g. Finally, the dry matter had a digestibility of 77.9% for red clover and 75.6% for alfalfa.

Streszczenie:

Since the beginning of human cultivation, the role of plants in medicine has been of huge importance. The aim of this PhD Project is to investigate some forage plants belonging to the family of Fabaceae to gain knowledge concerning their possible use in nutraceutical, pharmaceutical and cosmetics field. These plants have been chosen because they are characterized by great productive potential, but they are still under-exploited from the officinal and industrial point of view. They are also a potential source for the extraction of bioactive compounds with possible pharmaceutical and cosmetic applications (Rodrigues et al., 2013;Cornara et al., 2016), being generally rich in secondary metabolites such as alkaloids, amines, flavonoids, coumarins, condensed tannins and saponins (Burlando et al., 2010; Pastorino et al., 2017) To increase their use also in the industrial sector and, consequently, their commercial value, the study has focused on the identification of bioactive compounds with possible interest in human health. In this study a multidisciplinary approach was carried out, investigating several aspects such as antioxidant, antilipidemic and cytotoxicity strength, content of total phenols and flavonoids. In this PhD Project we studied four species of legumes: Melilotus officinalis (L.) Pall., Lespedeza capitata Michx., Sulla coronaria (L.) Medik and Glycyrrhiza glabra L. Thanks to a collaboration with Egadi S.r.l., Favignana, Italy, we also concentrated our study to another kind of plant, belonging to the family of Potamogetonaceae: Posidonia oceanica (L.) Delile. The species has shown bioactivities suitable for the development of cosmetic and dermatologic applications. In summary, the results of these investigations show new opportunities to exploit the plants studied plants in bioindustry processes, possibly increasing their commercial value.
