“…They may act as plant growth promoters; confer tolerance to environmental stresses and pathogen and herbivore attacks, the latter for instance by decreasing the palatability of the host tissue to herbivores through the production of toxic compounds (Arnold et al 2003;Miller et al 2008;Bae et al 2009;Oono et al 2015). The role of endophytes in pathogen defence is attained through different mechanisms, namely the induction of systemic resistance, through the accumulation of pathogenesis-related (PR) proteins, expression of plant defence genes; the production of secondary metabolites that inhibit fungal growth and the competition with pathogens for the same ecological niches in terms of nutrients and space (Arnold et al 2003;Gonzalez & Tello 2011). On the other hand, endophytic fungi benefit from protection and nutrition from their hosts, and in some cases, reproducing sexually on dead tissues of their host plant (Saikkonen et al 1998).…”

a b s t r a c tFungal endophytes present in different asymptomatic grapevine plants (Vitis vinifera L.) located in different vineyards within Alentejo, a highly important viticulture region in Portugal, were identified in this study. Sampled grapevine plants included the three most representative cultivars in the region, Syrah, Cabernet Sauvignon, and Aragonez, growing under two different modes of management, conventional and biological. Sixteen fungal taxa were identified through sequencing of the internal transcribed spacer region. Total number of endophytic fungi isolated showed significant differences both in management mode and in cultivars, with higher numbers in grapevines under conventional mode and from Syrah cultivar. The composition of fungal endophytic communities did not show significant differences among cultivars, but differences were observed between fungal communities isolated from grapevines under biological or conventional modes. The most fungal taxa isolated from grapevines cultivated under biological mode were Alternaria alternata, Cladosporium sp., and Nigrospora oryzae, and under conventional mode Botrytis cinerea, Epicoccum nigrum, and Epicoccum sp. These differences suggest that the different products used in grapevine production have impacts in fungal endophytic composition. Further investigation of the identified fungi with respect to their antagonistic characteristics and potential use in plant protection to ensure food safety is now in course.

“…Several authors have investigated the diversity and ecological role of endophytic fungal communities in Vitis vinifera L. (von Tiedemann et al 1988;Mostert et al 2000;Casieri et al 2009;González and Tello 2010). Among these communities, the genera Acremonium, Alternaria, Epicoccum and Fusarium have been shown to be effective as biocontrol agents of Plasmopara viticola (Berk.…”

Identification of Acremonium isolates from grapevines and evaluation of their antagonism towards Plasmopara viticola

et al. 2015

Some endophytic fungal genera in Vitis vinifera, including Acremonium, have been reported as antagonists of Plasmopara viticola. Endophytic Acremonium isolates from an asymptomatic grapevine cultivar Inzolia from Italy were identified by morphological features and multigene phylogenies of ITS, 18S and 28S genes, and their intra-specific genomic diversity was analyzed by RAPD analysis. Culture filtrates (CFs) obtained from Acremonium isolates were tested in vitro for their inhibitory activity against the P. viticola sporangia germination. Among 94 isolates, 68 belonged to the Acremonium persicinum and 26 to the Acremonium sclerotigenum. RAPD analysis grouped the A. persicinum isolates into 15 clusters and defined 31 different strains. The A. sclerotigenum isolates, instead, were clustered into 22 groups and represented 25 strains. All A. persicinum CFs inhibited sporangia germination of P. viticola, while not all those of A. sclerotigenum had inhibitory effect. A different degree of inhibition was observed between strains of the same species, while some strains of different species showed identical inhibitory effect. No correlation was found between RAPD groups and inhibitory activity in both Acremonium species.

Patogenicidade de espécies de Botryosphaeriaceae endofíticas de plantas da Caatinga do estado do Ceará em manga e umbu-cajá

Espécies de Botryosphaeriaceae são importantes patógenos em diversas plantas lenhosas e não lenhosas, causando diferentes tipos de sintomas. Espécies desta família são usualmente consideradas patógenos fracos, causando doenças apenas quando estas plantas se encontram sob algum tipo de estresse como seca, temperaturas baixas ou elevadas, deficiência nutricional e danos causados por outros patógenos ou pragas. No entanto, pouco se conhece sobre a ocorrência e diversidade de espécies de Botryosphaeriaceae em plantas nativas do bioma Caatinga, localizado no Semiárido, e sobre a presença de fungos endofíticos nessas espécies, e muito menos sobre a sua importância como patógenos. O objetivo do presente estudo foi avaliar a patogenicidade de 74 isolados representando Espécies de Botryosphaeriaceae (Dothideomycetes) têm distribuição mundial, sendo encontradas em todas as regiões geográficas, incluindo áreas de clima tropical, temperado e até em ambiente marinho, com exceção das regiões polares (2,34,35,38). Já foram relatadas infectando plantas do grupo das monocotiledôneas, dicotiledôneas e gimnospermas, e até liquens (1). Seus hospedeiros incluem uma diversidade de plantas de importância agronômica, florestal e ornamental (1, 8). Entre as doenças causadas por espécies de Botryosphaeriaceae estão podridão de frutos, manchas foliares, tombamento e podridão de colo em mudas, cancros, secas em brotos e mudas, gomose, seca descendente, vassoura-de-bruxa e morte de árvores (41).Espécies de Botryosphaeriaceae são frequentemente descritas como oportunistas ou patógenos latentes, os quais apresentam longo período de latência antes que algum fator como, por exemplo, estresse hídrico faça com que eles se tornem patogênicos, causando, frequentemente, cancros em seus hospedeiros (6,28,42,45). Essas espécies são bem conhecidas como endofíticas em uma variedade de plantas arbóreas. Entre as principais famílias botânicas já estudadas incluem-se Moraceae, Myrtaceae, Proteacea, Leguminosae, Pinaceae, Vitaceae e Anacardiaceae (6, 8, 9,15,16,24,27,29,42,43,44).No Ceará, o bioma Caatinga cobre uma área de 126.926 km 2 , ABSTRACTSpecies of the Botryosphaeriaceae are important pathogens in several woody and non-woody plants, causing different types of symptoms. Species of this family are usually regarded as weak pathogens, only causing diseases when plants are under some type of stress such as drought, hot or cold weather, poor nutrition and damage caused by other pathogens or pests. However, little is known about the occurrence and diversity of Botryosphaeriaceae species in native plants of the biome Caatinga, located in the Brazilian Semi-Arid Region, and about the presence of endophytic fungi in these species; even less is known about their importance as pathogens. The aim of the present study was to assess the pathogenicity of 74 isolates representing the species Botyosphaeria mamane, Pseudofusicoccum adansoniae, P. stromaticum, the complex Neofusicoccum parvum/ribis, Lasiodiplodia gonubiensis and L.theobromae, identified for the first ...
