This notion implies different evolutionary strategies of host exploitation. Typically, parasites establish long-term infections and induce relatively little mortality, as they often limit pathological changes by modulating host cells and downregulating adverse immune responses. Their pattern of distribution tends to be endemic rather than epidemic. Despite these seemingly benign traits, parasites usually cause substantial chronic morbidity, thus constituting an enormous socioeconomic burden in humans, particularly in resource poor countries, and in livestock worldwide. Parasite-induced fitness costs are an evolutionary force that can shape populations and contribute to species diversity. Therefore, a thorough understanding of parasites and parasitic diseases requires detailed knowledge of the respective biochemical, molecular and immunological aspects as well as of population genetics, epidemiology and ecology. This Research Topic (RT) bridges disciplines to connect molecular, immunological and wildlife aspects of parasitic infections. The RT puts emphases on four groups of parasites: Plasmodium, Toxoplasma, Giardia and intestinal helminths. Co-infections are also covered by the RT as they represent the most common form of parasite infections in wildlife and domestic animal populations. Within the four types of parasites the following topics are addressed: (1) Experimental models: hypothesis testing, translation and limits. (2) Critical appraisal of experimental models. (3) Natural systems: Technological advances for investigations in natural parasite-host systems and studies in natural systems. (4) The urgent need for better models and methods in natural parasite systems. Hence, the RT covers and illustrate by the means of four main parasitic infections the parasite-host system at the molecular, cellular and organismic level.Parasite InfectionsPlasmodislemacToxoplasmaHelminthProtozoaexperimental modelGiardiaParasite Infectionnatural systemPlasmodisToni Aebischerauth1329310Susanne HartmannauthKai MatuschewskiauthBOOK9910346737603321Parasite Infections: From Experimental Models to Natural Systems3039411UNINA06212nam 2201297z- 450 991055714770332120231214133443.0(CKB)5400000000040581(oapen)https://directory.doabooks.org/handle/20.500.12854/68526(EXLCZ)99540000000004058120202105d2021 |y 0engurmn|---annantxtrdacontentcrdamediacrrdacarrierGrafting as a Sustainable Means for Securing Yield Stability and Quality in Vegetable CropsBasel, SwitzerlandMDPI - Multidisciplinary Digital Publishing Institute20211 electronic resource (246 p.)3-0365-0392-7 3-0365-0393-5 Vegetable growers around the world only collect, on average, half of the yield they would obtain under optimal conditions, known as yield potential. It is estimated that 60–70% of the yield gap is attributable to abiotic factors such as salinity, drought, suboptimal temperatures, nutritional deficiencies, flooding, waterlogging, heavy metals contamination, adverse soil pH and organic pollutants, while the remaining 30–40% is due to biotic factors, especially soilborne pathogens, foliar pathogens, arthropods and weeds. Under climate change forecasts, the pressure of biotic/abiotic stressors on yield is expected to rise and challenge further global food security. To meet global demand, several solutions have been proposed, focusing on the breeding of varieties with greater yield potential, but this one-size-fits-all solution leads to limited benefits. In order to overcome the current situation, grafting of elite scion varieties onto vigorous rootstock varieties has been suggested as one of the most promising drives towards further yield stability. Specifically, the implementation of suitable rootstock × scion × environment combinations in Solanaceous (tomato, eggplant, pepper) and Cucurbitaceous (melon, watermelon, melon) high-value crops represents an untapped opportunity to secure yield stability and reliability under biotic/abiotic stresses. This Special Issue invites Original Research, Technology Reports, Methods, Opinions, Perspectives, Invited Reviews and Mini Reviews dissecting grafting as a sustainable agro technology for enhancing tolerance to abiotic stresses and reducing disease damage. In addition, the following are of interest: potential contributions dealing with genetic resources for rootstock breeding, practices and technologies of rootstock breeding, and rootstock–scion signaling, as well as the physiological and molecular mechanisms underlying graft compatibility. In addition, the effect of grafting on vegetable quality, practical applications and nursery management of grafted seedlings and specialty crops (e.g. artichoke and bean) will be considered within the general scope of the Special Issue. We highly believe that this compilation of high standard scientific papers on the principles and practices of vegetable grafting will foster discussions within this important field.Research & information: generalbicsscBiology, life sciencesbicsscTechnology, engineering, agriculturebicssctomato graftingsplice grafting techniquegraft anglerandom diameterwild eggplant relativeinterspecific hybridscion/rootstock combinationplant vigouryieldfruit quality attributescucumbergrafting techniquesrootstock-scionsoil-borne diseaseresistanttolerant crop growthfruit yieldfruit qualityLEDPPFDPsaAPsbAWestern BlotCucumis melo L.arsenicgraftingtranslocationbioaccumulationagricultural robotautomated graftingagricultural machineryTomato graftingsalinity tolerancerootstockphysio-biochemical mechanismsSolanum lycopresicum L.vegetable graftingSolanum melongena L.grafting combinationsarbuscular micorrhizal fungiyield traitsNUEmineral profilefunctional propertiesNaClCitrullus vulgaris SchradLuffa cylindrica MillC. maxima Duch. × C. moschata Duch.seedlingsmorpho-physiological traitssolanaceaecucurbitaceaedefense mechanismssoilborne pathogengenetic resistancemicrobial communitiessoil/root interfacereduced irrigationrootstocksleaf gas exchangeCitrullus lanatus (Thunb) Matsum and Nakaifunctional qualitylycopenestoragesugarstextureeggplant graftingsensory evaluationBrassicaceaegrowthmineral contentphotosynthesistaprootResearch & information: generalBiology, life sciencesTechnology, engineering, agricultureRouphael Youssefedt1328338Colla GiuseppeedtKyriacou MariosedtRouphael YoussefothColla GiuseppeothKyriacou MariosothBOOK9910557147703321Grafting as a Sustainable Means for Securing Yield Stability and Quality in Vegetable Crops3038788UNINA
