Coffee is one of the most consumed beverages in world. It also globally traded commodities. leaf rust (CLR), caused by biotrophic fungus Hemileia vastatrix, important disease affecting Arabica coffee growing worldwide, leading to significant yield losses if no control measures are applied. A deep understanding complex mechanisms involved coffee-H. vastatrix interactions, such as pathogen variability and governing plant resistance susceptibility, required breed efficiently for durable design...
The harvesting, processing, and sale of wild edible mushrooms (WEM) is a relevant economic activity in Angola good example the use non-wood forest products for food. Although there deep traditional knowledge about general properties WEMs, huge gap remains detailed scientific knowledge. Thus, this study aimed to investigate socio-economic importance species sold at local markets Huila, Angola, from their molecular identification assessment nutritional, chemical, bioactive profiles. From eight...
Esca is a grapevine trunk disease spreading in vineyards worldwide, and of rising concern since no efficient treatment available to mitigate its impact. Trunks, grapes leaves from symptomatic asymptomatic Aragonês vines were collected at harvest stage characterise plant responses associated with this fungal disease. Presence fungi the trunks was confirmed by molecular methods using ITS region. Metabolomics analysed Gas chromatography coupled electron impact ionization time-of-flight mass...
Understanding the molecular mechanisms underlying coffee-pathogen interactions are of key importance to aid disease resistance breeding efforts. In this work expression genes involved in salicylic acid (SA), jasmonic (JA) and ethylene (ET) pathways were studied hypocotyls two coffee varieties challenged with hemibiotrophic fungus Colletotrichum kahawae, causal agent Coffee Berry Disease. Based on a cytological analysis, time-points infection process selected qPCR was used evaluate...
Colletotrichum kahawae is a specialized plant pathogen of arabica coffee in Africa, able to infect green berries. The economic impact this means there an urgent need better understand its pathogenic lifestyle, particular aggressiveness. In study, several quantitative traits including disease severity, latent period and incubation were measured concomitantly assess the aggressiveness 26 C. isolates. results show that area under progression curve most informative variable, particularly when...
Black foot of grapevine is an important disease caused primarily by Ilyonectria spp. and “ Cylindrocarpon ” pauciseptatum . These pathogens affect nurseries young vineyards, causing the decline death plants. In nursery, primary infections grafted cuttings are mainly attributed to soil-borne inoculum, which could infect roots basal end rootstocks during rooting stage. The aim this research was detect other possible sources inoculum throughout different nursery stages classical molecular...
Abstract The biotrophic fungus Erysiphe necator causes powdery mildew (PM) in grapevine. Phytohormones are major modulators of defensive responses plants but the analysis hormonome associated with grapevine tolerance and susceptibility against this pathogen has not been elucidated. In study, changes hormonal profiling were compared between a tolerant ( Vitis rupestris × riparia cv. 101-14 Millardet et de Grasset) susceptible vinifera Aragonêz) species upon E. infection. Control PM-infected...
Grapevine trunk diseases constitute one of the major problems for viticulture worldwide, with Botryosphaeria dieback considered as most important these diseases. In this work, we aimed to (i) evaluate effect combination two products, Esquive® (a Trichoderma-based product) and LC2017 low-copper-based product), in control Lasiodiplodia theobromae, by evaluating internal lesion length caused inoculation pathogen on greenhouse kept grapevines cvs Cabernet Sauvignon Touriga Nacional and, (ii)...

Postharvest losses of fruits may reach in some cases 40% developed countries. This food waste has a significant carbon footprint and makes major contribution toward greenhouse gas emissions so sustainable postharvest strategies are being investigated. Melatonin, well-known mammalian neurohormone, been investigated as priming agent to slow down fungal decay progression climacteric non-climacteric fruits. However, the molecular metabolic mechanisms responsible for such enhancement disease...
Abstract The oomycete P. cinnamomi has been described as strong contributing factor to the decline of cork oak and holm stands occurring in Iberian Peninsula. There are no eradication methods available against this pathogen. Molecular mechanisms — host interaction not well understood, but it is known that species can induce biochemical physiological processes their plants through a diverse array virulence or avirulence molecules, effectors. Several Phytophtora effector elicitins, able...
