[Ab] Resumo:BACKGROUND: Wild vegetables in the Mediterranean Basin are still often consumed as a part of the diet and, in particular, there is a great tradition regarding their use in Sicily. In this study, an ethnobotanical field investigation was carried out to (a) identify the wild native taxa traditionally gathered and consumed as vegetables in Sicily, comparing the collected ethnobotanical data with those of other countries that have nominated the Mediterranean diet for inclusion in the UNESCO Representative List of the Intangible Cultural Heritage of Humanity and (b) highlight new culinary uses of these plants. METHODS: Interviews were carried out in 187 towns and villages in Sicily between 2005 and 2015. A total of 980 people over the age of 50 were interviewed (mainly farmers, shepherds, and experts on local traditions). Plants recorded were usually collected in collaboration with the informants to confirm the correct identification of the plants. The frequencies of citation were calculated. RESULTS: Two hundred fifty-three taxa (specific and intraspecific) belonging to 39 families, and 128 genera were recorded (26 were cited for the first time). The most represented families were Asteraceae, Brassicaceae, Apiaceae, Amaryllidaceae, Malvaceae, and Polygonaceae. Only 14 taxa were cited by 75% of the people interviewed. The aerial parts of wild plants, including leaves, tender shoots, and basal rosettes, are the main portions collected, while the subterranean parts are used to a lesser extent. For some vegetables, more parts are utilized. Most of the reported vegetables are consumed cooked. In addition to the widely known vegetables (Borago officinalis, Beta spp., Cichorium spp., Brassica spp., Carduus spp., etc.), the so-called ancient vegetables are included (Onopordum illyricum, Centaurea calcitrapa, Nasturtium officinale, Scolymus spp., Smyrnium rotundifolium), and some unique uses were described. Comparing the Sicilian findings to those from other countries, a very high number of vegetable taxa were detected, 72 of which are eaten only in Sicily, while 12 are consumed in all the Mediterranean countries examined. CONCLUSIONS: The research shows a high level of Sicilian knowledge about using wild plants as a traditional food source. Wild vegetables are healthy and authentic ingredients for local and ancient recipes, which are fundamental to the revitalization of quality food strictly connected to traditional agroecosystems.

[Ti] Título:A Nanobionic Light Emitting Plant.

[La] Idioma:eng
[Ab] Resumo:The engineering of living plants for visible light emission and sustainable illumination is compelling because plants possess independent energy generation and storage mechanisms and autonomous self-repair. Herein, we demonstrate a plant nanobionic approach that enables exceptional luminosity and lifetime utilizing four chemically-interacting nanoparticles, including firefly luciferase conjugated silica (SNP-Luc), D-luciferin releasing poly(lactic-co-glycolic acid) (PLGA-LH2), coenzyme A functionalized chitosan (CS-CoA) and semiconductor nanocrystal phosphors for longer wavelength modulation. An in vitro kinetic model incorporating the release rates of the nanoparticles is developed to maximize the chemiluminescent lifetimes to exceed 21.5 hours. In watercress (Nasturtium officinale) and other species, the nanoparticles circumvent limitations such as luciferin toxicity above 400 µM and co-localization of enzymatic reactions near high adenosine triphosphate (ATP) production. Pressurized bath infusion of nanoparticles (PBIN) is introduced to deliver mixture of nanoparticles to the entire living plant, well described using a nanofluidic mathematical model. We rationally design nanoparticle size and charge to control localization within distinct tissues compartments, with 10 nm nanoparticles localizing within the leaf mesophyll and stomata guard cells, and those larger than 100 nm segregated in the leaf mesophyll. The results are mature watercress plants that emit greater than 1.44·1012 photons/sec or 50% of 1 µW commercial luminescent diodes and modulate 'off' and 'on' states by chemical addition of dehydroluciferin and coenzyme A, respectively. We show that CdSe nanocrystals can shift the chemiluminescent emission to 760 nm enabling near infrared (nIR) signaling. These results advance the viability of nanobionic plants as self-powered photonics, direct and indirect light sources.

[Ti] Título:Transcriptional responses to short-term and long-term host plant experience and parasite load in an oligophagous beetle.

[La] Idioma:eng
[Ab] Resumo:Oligophagous herbivores must adjust their enzymatic machinery to the different host plant species they consume. If different hosts are used from one generation to the next, adaptation may be highly plastic, while if a single host is used over several generations, there may be a longer-term response due to natural selection. Using an experimental evolutionary approach, we investigated effects of long-term experience vs. short-term responses to different host plants in the oligophagous mustard leaf beetle Phaedon cochleariae. After 26 generations of continuous feeding on either Brassica rapa, Nasturtium officinale or Sinapis alba, freshly hatched larvae were kept on these plants or moved to one of the other host plants for ten days. Global transcriptional patterns as shown by microarrays revealed that between 1% and 16.1% of all 25,227 putative genes were differentially expressed in these treatments in comparison with the control line constantly feeding on B. rapa. A shift back from S. alba to B. rapa caused the largest changes in gene transcription and may thus represent the harshest conditions. Infection rates with a gregarine parasite were intermediate in all lines that were constantly kept on one host, but much lower or higher when short-term shifts to other host plants occurred. In conclusion, transcriptional plasticity in genes related to metabolism, digestion and general cellular processes plays a key role in long- and short-term responses of the beetle to changing host plant conditions, whereby the specific conditions also affect the interactions between the beetle host and its gregarine parasite.

[Ti] Título:The spitting image of plant defenses: Effects of plant secondary chemistry on the efficacy of caterpillar regurgitant as an anti-predator defense.

[Ab] Resumo:In the arms race between plants, herbivores, and their natural enemies, specialized herbivores may use plant defenses for their own benefit, and variation in plant traits may affect the benefits that herbivores derive from these defenses. is a specialist herbivore of plants containing glucosinolates, a specific class of defensive secondary metabolites. Caterpillars of are known to actively spit on attacking natural enemies, including their main parasitoid, the braconid wasp . Here, we tested the hypothesis that variation in the secondary metabolites of host plants affects the efficacy of caterpillar regurgitant as an anti-predator defense. Using a total of 10 host plants with different glucosinolate profiles, we first studied natural regurgitation events of caterpillars on parasitoids. We then studied manual applications of water or regurgitant on parasitoids during parasitization events. Results from natural regurgitation events revealed that parasitoids spent more time grooming after attack when foraging on radish and nasturtium than on spp., and when the regurgitant came in contact with the wings rather than any other body part. Results from manual applications of regurgitant showed that all parameters of parasitoid behavior (initial attack duration, attack interruption, grooming time, and likelihood of a second attack) were more affected when regurgitant was applied rather than water. The proportion of parasitoids re-attacking a caterpillar within 15 min was the lowest when regurgitant originated from radish-fed caterpillars. However, we found no correlation between glucosinolate content and regurgitant effects, and parasitoid behavior was equally affected when regurgitant originated from a glucosinolate-deficient mutant line. In conclusion, host plant affects to a certain extent the efficacy of spit from caterpillars as a defense against parasitoids, but this is not due to glucosinolate content. The nature of the defensive compounds present in the spit remains to be determined, and the ecological relevance of this anti-predator defense needs to be further evaluated in the field.

[Ti] Título:Pathogenic, phenotypic and molecular characterisation of Xanthomonas nasturtii sp. nov. and Xanthomonas floridensis sp. nov., new species of Xanthomonas associated with watercress production in Florida.

[Ab] Resumo:We describe two new species of the genus Xanthomonas, represented by yellow mucoid bacterial strains isolated from diseased leaves of watercress (Nasturtium officinale) produced in Florida, USA. One strain was pathogenic on watercress, but not in other species including a range of brassicas; other strains were not pathogenic in any of the tested plants. Data from Biolog carbon source utilization tests and nucleotide sequence data from 16S and gyrB loci suggested that both pathogenic and non-pathogenic strains were related to, yet distinct from, previously described Xanthomonas species. Multilocus sequence analysis and whole genome-wide comparisons of the average nucleotide identity (ANI) of genomes of two strains from watercress showed that these are distinct and share less than 95 % ANI with all other known species; the non-pathogenic strain WHRI 8848 is close to Xanthomonascassavae (ANI of 93.72 %) whilst the pathogenic strain WHRI 8853 is close to a large clade of species that includes Xanthomonasvesicatoria (ANI ≤90.25 %). Based on these results, we propose that both strains represent new Xanthomonas species named Xanthomonas floridensis sp. nov. (type strain WHRI 8848=ATCC TSD-60=ICMP 21312=LMG 29665=NCPPB 4601) and Xanthomonas nasturtii sp. nov. (type strain WHRI 8853=ATCC TSD-61=ICMP 21313=LMG 29666=NCPPB 4600), respectively. The presence of non-pathogenic Xanthomonas strains in watercress and their interaction with pathogenic strains needs to be further investigated. Although the importance of the new pathogenic species is yet to be determined, the bacterial disease that it causes constitutes a threat to watercress production and its distribution should be monitored.

[Ab] Resumo:The purpose of this study is to determine whether the allelopathy of living Myriophyllum aquaticum and its straw has the same effects; two pot experiments were conducted to study the effects of intercropping using M. aquaticum and its straw on the growth and cadmium (Cd) accumulation of Nasturtium officinale. Different planting ratios (1:3, 2:2 and 3:1) of N. officinale and M. aquaticum led to an increase in the biomass of both plant species and increased the Cd content in roots and shoots of N. officinale, but led to a reduction in the Cd content in roots and shoots of M. aquaticum. When the intercropping ratio of N. officinale and M. aquaticum was 3:1, the Cd amount in whole plants reached the maximum of 293.96 µg pot . Mulching the straw of M. aquaticum roots on the soil surface increased the biomass of N. officinale, but mulching the straw of M. aquaticum stems and leaves led to a decrease. Mulching the straw of roots, stems and leaves of M. aquaticum reduced Cd content and amounts in roots and shoots of N. officinale. Intercropping with M. aquaticum can improve the Cd uptake ability of N. officinale, but mulching M. aquaticum straw can reduce its Cd uptake ability.

[Ab] Resumo:The present study describes the effects of Watercress extract (WE) based electrospun nanofibrous mats on the regulation of adhesion, proliferation, cytoprotection and stemness preservation of adipose-derived stem cells (ADSCs). Watercress (Nasturtium officinale) is one of the most important medicinal plant with a board spectrum of biological functions. For this purpose, WE-loaded PCL-PEG nanofibers were fabricated by electrospinning and characterized using FE-SEM and FTIR. Adhesion, proliferation and cytoprotection of ADSCs on the nanofibers was investigated using FE-SEM and MTT assays. Analysis of cell cycle was carried out by flow-cytometry. Finally, qPCR was applied to measure the expression levels of cell cycle-regulated genes and stemness markers of ADSCs grown on the nanofibers. In this study, we found that WE-loaded PCL-PEG nanofibers had great antioxidant potential and exhibited higher cytoprotection, better adhesion, and significantly increased proliferation of ADSCs. The greater proliferation and preserving stemness ability of ADSCs on WE based nanofibers was further confirmed by higher expression levels of cell cycle-regulated genes and stemness markers. These results demonstrate that WE-loaded PCL-PEG electrospun nanofibrous mats appear suitable to support ADSCs adhesion and proliferation while concurrently preserving the cell stemness, therefore representing a hopeful approach for applying in stem cell based regenerative medicine.

[Ab] Resumo:With the development of economy, the heavy metal contamination has become an increasingly serious problem, especially the cadmium (Cd) contamination. The emergent plant Nasturtium officinale R. Br. is a Cd-accumulator with low phytoremediation ability. To improve Cd phytoextraction efficiency of N. officinale, the straw from Cd-hyperaccumulator plants Youngia erythrocarpa, Galinsoga parviflora, Siegesbeckia orientalis, and Bidens pilosa was applied to Cd-contaminated soil and N. officinale was then planted; the study assessed the effect of hyperaccumulator straw on the growth and Cd accumulation of N. officinale. The results showed that application of hyperaccumulator species straws increased the biomass and photosynthetic pigment content and reduced the root/shoot ratio of N. officinale. All straw treatments significantly increased Cd content in roots, but significantly decreased Cd content in shoots of N. officinale. Applying hyperaccumulator straw significantly increased the total Cd accumulation in the roots, shoots, and whole plants of N. officinale. Therefore, application of straw from four hyperaccumulator species promoted the growth of N. officinale and improved the phytoextraction efficiency of N. officinale in Cd-contaminated paddy field soil; the straw of Y. erythrocarpa provided the most improvement.

[Ab] Resumo:: Edible flowers, Tropaeolum majus has been used as a disinfectant and an antibiotic, and for wound healing, but the anti-obesity effects of this plant have not been reported previously : We investigated the anti-adipogenic effects of  ethanol extract (TME) on 3T3-L1 cells. : 3T3-L1 cells were differentiated in the presence of different concentrations of TME. Lipid accumulation levels were determined using Oil-Red O staining and a triglyceride content assay. Changes in the expression of proteins related to adipocyte differentiation in 3T3-L1 cells were determined by SDS-PAGE and western blotting. : The highest inhibition of lipid accumulation was observed at a TME concentration of 300 µg/mL. Additionally, TME concentrations ranging from 20 µg/mL to 500 µg/mL led to a decrease in the expression of adipocyte differentiation regulators, peroxisome proliferator-activated receptor γ, CCAAT element binding protein α, and sterol regulatory element binding transcription factor 1. This decrease was shown to be concentration-dependent. : Taken together, the results of this study demonstrate that TME inhibits lipid accumulation and reduces the expression PPARG, CEBPA, and SREBF1, which regulate adipocyte differentiation in 3T3-L1 cells. : TME may be a potential novel therapeutic agent for the prevention and treatment of obesity.

[Ab] Resumo:Watercress (Nasturtium officinale, Cruciferae; W. Aiton) is a vegetable widely consumed in our country, with nutritional and potentially chemopreventive properties. Previous reports from our laboratory demonstrated the protective effect of watercress juice against DNA damage induced by cyclophosphamide in vivo. In this study, we evaluated the in vivo effect of cress plant on the oxidative stress in mice. Animals were treated by gavage with different doses of watercress juice (0.5 and 1g/kg body weight) for 15 consecutive days before intraperitoneal injection of cyclophosphamide (100 mg/kg body weight). After 24 h, mice were killed by cervical dislocation. The effect of watercress was investigated by assessing the following oxidative stress biomarkers: catalase activity, superoxide dismutase activity, lipid peroxidation, and glutathione balance. Intake of watercress prior to cyclophosphamide administration enhanced superoxide dismutase activity in erythrocytes with no effect on catalase activity. In bone marrow and liver tissues, watercress juice counteracted the effect of cyclophosphamide. Glutathione balance rose by watercress supplementation and lipid oxidation diminished in all matrixes when compared to the respective control groups. Our results support the role of watercress as a diet component with promising properties to be used as health promoter or protective agent against oxidative damage.
