Ilyonectria radicicola and its Cylindrocarpon-like anamorph represent a species complex that is commonly associated with root rot disease symptoms on range of hosts. During the course this study, several could be distinguished from I. sensu stricto based morphological culture characteristics. DNA sequence analysis partial β-tubulin, histone H3, translation elongation factor 1-α nuclear ribosomal RNA-Internal Transcribed Spacer (nrRNA-ITS) genes were employed to provide further support for...
ABSTRACT Anthracnose ( Colletotrichum spp.) is an important disease causing major yield losses and poor oil quality in olives. The objectives were to determine the diversity distribution pattern of spp. populations prevalent olives their relatedness anthracnose pathogens other hosts, assess pathogenic variability host preference, develop diagnostic tools. A total 128 isolates representing all olive-growing areas Portugal a few from countries characterized by molecular phenotypic assays...
Esca is a disease complex belonging to the grapevine trunk diseases cluster. It comprises five syndromes, three main fungal pathogenic agents and several symptoms, both internal (e.g. affecting stem) external (i.e. leaves bunches). The etiology epidemiology of this remain, in part, unclear. Some points that are still under discussion concern sudden rise incidence, simultaneous presence multiple wood pathogens affected grapevines, causal discontinuity time foliar symptoms manifestation....
Anthracnose, caused by Colletotrichum sp., is a serious problem of lupins (Lupinus spp.) worldwide. Morphological characters and molecular markers were used to characterize 43 isolates from lupins, 8 other hosts, 18 reference representing related spp., assess the pathogen diversity resolve its taxonomy. All lupin tested positive with C. acutatum-specific polymerase chain reaction (PCR) did not test gloeosporioides-specific PCR. Spore shape colony diameter as well insensitivity benomyl...
Summary Olive anthracnose causes fruit rot leading to its drop or mummification, resulting in yield losses and the degradation of oil quality. Taxonomy distribution The disease is caused by diverse species Colletotrichum , mostly clustering C. acutatum complex. nymphaeae godetiae are prevalent Northern Hemisphere, whereas sensu stricto most frequent Southern although it recently quickly emerging Hemisphere. has been reported from all continents, but attains higher incidence severity west...
Epicoccum is a genus of ascomycetes often associated with the mycobiome grapevines (Vitis vinifera). spp. are found in soil, phyllosphere, as well wood, where they interact both plant and other endophytes pathogens. Wood pathogens involved esca disease complex, grapevine trunk disease, particularly concerning viticulture, current control strategies have proven unsatisfactory. This study investigated interaction among three esca-associated fungi, aim establishing whether suitable candidates...
Black foot disease is a serious of grapevine crops in most areas where vines are grown. Mainly two species Cylindrocarpon, C. destructans and macrodidymum, associated with this disease. Recent studies have revealed tremendous molecular variation within the former but only slight latter, indicating that presents complex several The present study elucidates taxonomic status destructans-like isolates black grapevines. Grapevine were studied morphologically, subjected to DNA analyses their ITS...
Anthracnose is an important disease affecting mature olive fruits, causing significant yield losses, and poor fruit oil quality. In Portugal, high anthracnose incidence was recorded during 2003–2007 with 41% of 908 orchards surveyed displaying symptoms. another 14% the orchards, pathogen in symptomless plants. Disease severity on average 36%, frequently reaching 100%. endemic to neglected susceptible cultivars, but under favourable conditions it can also severely affect less cultivars....
This study aims to describe the design, methods and sample characteristics of Multidimensional Evaluation Treatment Anxiety in Children Adolescents - PROTAIA Project.Students between 10 17 years old from all six schools belonging catchment area Primary Care Unit Hospital de Clínicas Porto Alegre were included project. It comprises five phases: (1) a community screening phase; (2) psychiatric diagnostic (3) multidimensional assessment phase evaluating environmental, neuropsychological,...
The genus Colletotrichum has witnessed tremendous variations over the years in number of species recognized, ranging from 11 to several hundreds. Host-specific fungal species, once rule, are now exception, with polyphagous behavior regarded as normal this genus. kahawae was created accommodate pathogens that have unique ability infect green developing coffee berries causing devastating Coffee Berry Disease Africa, but its close phylogenetic relationship a group fungi C. gloeosporioides...
In an attempt to determine the aetiology of young vine decline in Portugal a study was carried out in rootstock nurseries and vineyards during last few years. Rootstock located most important production areas (Ribatejo-Oeste Beira Litoral) were surveyed. The fungi frequently isolated from discoloured wood at base stem Cylindrocarpon destructans Phaeoacremonium spp., although Acremonium sp., Phomopsis Fusarium spp., Fusicoccum Gliocladium Phoma sp. Sphaeropsis sp. also present. Young vines...
† Contributed equally to the work Summary. The effect of Phaeomoniella chlamydospora infection was evaluated in three grapevine cultivars, relation variation phenolic compounds within host. Young plants Vitis vinifera (cv. Chardonnay, Touriga Nacional and two clones cv. Aragonez) were infected using strains Pa. harvested after fi ve months from inoculation. Overall, a localised increment amount total phenolics methanolic extract wood tissue observed following infection. Such pattern also...
Abstract Background Hypertrophic Cardiomyopathy (HCM) is a complex myocardial disorder with recognized genetic heterogeneity. The elevated number of genes and mutations involved in HCM limits gene-based diagnosis that should be considered most importance for basic research clinical medicine. Methodology In this report, we evaluated High Resolution Melting (HRM) robustness, regarding testing, by means analyzing 28 HCM-associated genes, including the frequent 4 sarcomere as well 24 lower...
Anthracnose is the most important disease of olives responsible for olive oil depreciation. The aim this study to compare negative effects common anthracnose pathogens in Portugal, Colletotrichum nymphaeae, C. godetiae, or acutatum, on extracted from fruits cultivated Portuguese cultivars, ‘Galega Vulgar’ and ‘Cobrançosa’. Healthy (ripening index 3.5) were inoculated, incubated, sampled over 14 days post-inoculation (d.p.i.) symptom assessment extraction. Virgin (VOO) was characterised by...
Anthracnose (Colletotrichum spp.) is an important disease of olive fruits. Diversity and biogeographic relationships the anthracnose pathogens in Algarve (Portugal) were investigated, along with host association patterns levels during 2004-2007, to test hypothesis that this region a host-pathogen diversity hot spot. Diverse Colletotrichum acutatum gloeosporioides populations identified based on rRNA-internal transcribed spacer partial beta-tubulin 2 gene sequences 95 isolates. Spatial...
Black foot is an important disease of grapevines, affecting vines in nurseries as well young plantations. In recent years the has increased incidence and severity throughout world. associated with at least two Campylocarpon 12 Ilyonectria species, most which have only recently been described. The recognition previously unknown together published reports variability virulence between within species identified I. macrodidyma liriodendri , underlined need to compare isolates from these...
Olive anthracnose, caused by Colletotrichum fungi, is responsible for major fruit yield losses and poor olive oil quality worldwide. In the Mediterranean basin, some spp. appear to be replacing others, possibly due climate change modification in cultural systems. To update situation Portugal, 525 groves were surveyed throughout country over two years, revealing a decrease disease incidence, associated with scarcer rainfall new cropping systems using less susceptible cultivars. A collection...
DNA chains with sequential guanine (G) repeats can lead to the formation of G-quadruplexes (G4), which are found in functional and RNA regions like telomeres oncogene promoters. The development molecules adequate structural features selectively stabilize G4 structures counteract cell immortality, highly described for cancer cells, also downregulate transcription events underlying apoptosis and/or senescence processes. We describe here, efficiency four charged porphyrins-phosphonium...
