Oomycetes in the class Saprolegniomycetidae of Eukaryotic kingdom Stramenopila have evolved as severe pathogens amphibians, crustaceans, fish and insects, resulting major losses aquaculture damage to aquatic ecosystems. We sequenced 63 Mb genome fresh water pathogen, Saprolegnia parasitica. Approximately 1/3 assembled exhibits loss heterozygosity, indicating an efficient mechanism for revealing new variation. Comparison S. parasitica with plant pathogenic oomycetes suggests that during...
Abstract ARGONAUTE proteins (AGOs) are known to be key components of the RNA silencing mechanism in eukaryotes that, among other functions, serves protect against viral invaders. Higher plants encode at least 10 individual AGOs yet role played by many silencing-related antiviral defense is largely unknown, except for reports that AGO1, AGO2, and AGO7 play an Arabidopsis (Arabidopsis thaliana). In plant virus model host Nicotiana benthamiana, Tomato bushy stunt (TBSV) P19 suppressor mutants...
Hemibiotrophic plant pathogens, such as the oomycete Phytophthora infestans, employ a biphasic infection strategy, initially behaving biotrophs, where minimal symptoms are exhibited by plant, and subsequently necrotrophs, feeding on dead tissue. The regulation of this transition breadth molecular mechanisms that modulate defences not well understood, although effector proteins secreted pathogen thought to play key role. We examined transcriptional dynamics P. infestans in compatible...
Avocado (Persea americana) is one of the most important crops in Mexico as it main producer, consumer and exporter avocado fruit world. However, successful commercialization often reduced by large postharvest losses due to Colletotrichum sp., causal agent anthracnose. Chitosan known have a direct antifungal effect acts also an elicitor capable stimulating defense response plants. there little information regarding genes that are either activated or repressed fruits treated with chitosan. The...

Abstract Background In-depth sequencing analysis has not been able to determine the overall complexity of transcriptional activity a plant organ or tissue sample. In some cases, deep parallel Expressed Sequence Tags (ESTs), although yet optimized for cDNAs, represented an efficient procedure validating gene prediction and estimating coverage. This approach could be very valuable complex genomes. addition, little emphasis given efforts aiming at estimation universe found in multicellular...
Nonhost resistance is a commonly occurring phenomenon wherein all accessions or cultivars of plant species are resistant to strains pathogen and likely the manifestation multiple molecular mechanisms. Phytophthora capsici soil-borne oomycete that causes blight disease in many solanaceous cucurbitaceous plants worldwide. Interest P. has increased considerably with sequencing its genome increasing occurrence crops. However, interactions between both hosts nonhosts poorly defined. We show here...
Summary The infection of plants by hemibiotrophic pathogens involves a complex and highly regulated transition from an initial biotrophic, asymptomatic stage to later necrotrophic state, characterized cell death. Little is known about how this regulated, there are conflicting views regarding the significance plant hormones jasmonic acid ( JA ) salicylic SA in different phases infection. To provide broad view process perspective, we surveyed transcriptome tomato S olanum lycopersicum during...
Pathogens are able to deliver small-secreted, cysteine-rich proteins into plant cells enable infection. The computational prediction of effector remains one the most challenging areas in study fungi interactions. At present, there several bioinformatic programs that can help identification these proteins; however, cases, managed independently. Here, we present EffHunter, an easy and fast bioinformatics tool for effectors. This predictor was used identify putative effectors 88 proteomes using...
Abstract Candida albicans is the most predominant fungal species isolated from medical devices, including catheters, heart valves, and dental prostheses. In recent years, it has been demonstrated to be resistant many antifungals; therefore, silver nanoparticles (AgNPs) have proposed as an alternative. But only a handful of research contributed omic-based studies study various impacts AgNPs on other microorganisms. Thus, aims biosynthesize using Pelargonium-hortorum leaf test its antifungal,...
Circumstantial evidence suggests that the genome of Faba bean necrotic yellows virus (FBNYV), a nanovirus, consists eight distinct, circular, single-stranded DNAs, each about 1 kb and encoding only one protein. Here, use cloned full-length FBNYV DNAs for reproducing FBNYV-like symptoms in Vicia faba, principal natural host FBNYV, is reported. Characteristic infection were obtained faba plants following biolistic DNA delivery or agroinoculation with all DNAs. Although different have been...
Abstract Several fungicide products with metalaxyl-chlorothalonil as the active ingredients are available in Mexican market. Applying containing this mixture of molecules is a common method that farmers choose to prevent damage caused crops by Phytophthora capsici . Despite efficacy controlling growth pathogen, their intensive use could contribute development multidrug-resistant strains. Additionally, dynamics resistance commercial metalaxyl-chlorothalonil-based fungicides and virulence P....
The internalization of some oomycete and fungal pathogen effectors into host plant cells has been reported to be blocked by proteins that bind the effectors' cell entry receptor, phosphatidylinositol-3-phosphate (PI3P). This finding suggested a novel strategy for disease control engineering plants secrete PI3P-binding proteins. In this study, we tested using chocolate tree Theobroma cacao. Transient expression secretion four different in detached leaves T. cacao greatly reduced infection two...
Papaya ringspot virus (PRSV), a common potyvirus infecting papaya plants worldwide, can lead to either antagonism or synergism in mixed infections with mosaic (PapMV), potexvirus. These two unrelated viruses produce depending on their order of infection the plant. When PRSV is inoculated first at same time as PapMV, viral interaction synergistic. However, an antagonistic response observed when PapMV before PRSV. In condition, deterred from plant and its drastic effects are overcome. Here, we...
