The fungal endophytic–host relationships of Discula umbrinella and two oak species, Quercus alba and Quercus rubra, were characterized on the basis of endophytic infection, pathogenicity, and mycelial compatibility. Isolates of D. umbrinella were cultured from leaves of Q. alba and Q. rubra collected from a hardwood forest located in Patuxent Wildlife Research Center in Laurel, Maryland, USA. Endophytic infection was observed on sterile leaf discs and living 2-month-old seedlings of Q. alba and… Expand

Species- and organ-specificity in endophytes colonizing healthy and declining Mediterranean oaks
Understanding is advanced of the role of some pathogenic fungal endophytes in Mediterranean oak forests and how interaction between plant species and the environment and continued competitive interaction between endophyte species may have led to niche diversification. Expand
The Holomorph Apiognomonia quercina/Discula quercina as a Pathogen/Endophyte in Oak
The evidence suggests that changes in the climate profoundly alter the plant-endophyte symbiosis, generating conflicts of interest between the partners in the interaction, and the symbiosis from mutualistic or neutral turns antagonistic. Expand
Fungal endophytes in Mediterranean oak forests: a lesson from Discula quercina.
It is postulated here that climatic factors can change the endophytic nature of D. quercina, turning it into a weak pathogen or an opportunistic invader of senescing and indeed healthy trees, in an unstable equilibrium between transient mutualism/neutralism and latent pathogenesis. Expand
A new species is described based on the association with Castanea sativa, morphology and phylogenetic analysis of the ITS region of ribosomal DNA and on the EF1-a locus, which is consistently associated with nut rot and caused the disease when artificially inoculated to fruits or flowers. Expand
Host Selectivity and Genetic Variation of Discula umbrinella Isolates from Two Oak Species: Analyses of Intergenic Spacer Region Sequences of Ribosomal DNA
Isolates within each IGS group were further analyzed for nucleotide polymorphisms to confirm genotype identity and genotype diversity to identify IGS groups (groups I–V) based on single nucleotide sequence differences. Expand
The influence of altitude on endophytic mycobiota in Quercus acuta leaves collected in two areas 1000 km apart
Summary Endophytic fungi were isolated from healthy leaves of the evergreen oak Quercus acuta on Mt Takao in eastern Honshu and on Mt Osuzu in Kyushu, Japan, to study the effect of altitude onExpand
Botryosphaeriaceae species overlap on four unrelated, native South African hosts.
The results suggest that some intrinsic host factors, possibly combined with local environmental conditions, affect the distribution and co-infectivity of various hosts by the Botryosphaeriaceae, which would counteract the general ability of a species in the family to infect a broad range of plants. Expand
Epidemiological Investigations Shed Light on the Ecological Role of the Endophyte Phomopsis quercina in Mediterranean Oak Forests
The increasing presence and abundance of P. quercina in declining (and especially drought-stressed) oaks suggests that climate change is having a significant role in destabilising the precarious balance between the host tree and the fungus, to the benefit of the latter. Expand
Phylogenetic Study of the Botryosphaeriaceae Species Associated with Avocado and Par rubber in Thailand
Species of fungi in the family Botryosphaeriaceae have a cosmopolitan distribution with a wide range of plant hosts and several species are associated with cankers, decline, dieback and rot diseases.Expand
Pervasiveness of endophytic fungal diversity in Anisomeles malabarica from Aliyar, Western Ghats, South India
The colonization rate was higher during the winter than in the monsoon and summer seasons, and the higher colonization frequency was found in mature leaves than in young leaves. Expand


Analysis of Discula quercina isolates from Quercus spp.
Twenty-five isolates of D. quercina from a number of Italian administrative Regions were tested to determine growth rate, acervuli formation capacity in vitro on agar and oak leaf extract, and heterokaryon formation capacity, and to detect vegetative compatibility among isolates. Expand
Morphometric evidence for host-specific strain formation in Discula umbrinella.
Analysis of large spore populations by electronic sizing evidenced a bi-modal distribution in most isolates studied, and in four Fagus isolates microconidia were evident as a third peak that coincided exactly with the main peak of the Quercus and Castanea isolates. Expand
Fungal endophytes from the leaves and twigs of Quercus ilex L. from England, Majorca and Switzerland.
Leaves of Quercus ilex taken from sites in England, Majorca and Switzerland have been studied to detect the influence of the geographic position of the host within and outside its native range on theExpand
Technique for large scale isolation of Discula umbrinella and other foliar endophytic fungi from Quercus species
This technique provides an efficient means to collect large numbers of fungal isolates necessary for fungal ecology and genetic variation studies and is easily modified for isolation of other fungi residing within a leaf. Expand
Differential attachment by conidia of the endophyte, Discula umbrinella (Berk. & Br.) Morelet, to host and non-host surfaces.
Differential attachment of conidia to leaves of different species (host and non-host) has been observed in the endophytic fungus, Discula umbrinella (Berk. & Br.) Morelet, a deuteromycete known toExpand
Endophytic Leptostroma species on Picea abies, Abies alba, and Abies balsamea: a cultural, biochemical and numerical study
The hypothesis that distinct species of Leptostroma, which are morphologically almest indistinguishable from each other, colonize apparently healthy needles of A. alba, A. balsamea, and P. abies is supported. Expand
Ecology, metabolite production, and substrate utilization in endophytic fungi.
The production of growth promoting factors and of metabolites useful in the pharmaceutical and agricultural industry is widespread among endophytic fungi, and their usefulness in agricultural and pharmaceutical research is briefly discussed. Expand
Fungal Endophytes of Tree Leaves
Carroll’s definition of endophyte is proposed to be expanded to include all organisms inhabiting plant organs that at some time in their life, can colonize internal plant tissues without causing apparent harm to their host. Expand
Mycelial interactions inSclerotinia sclerotiorum
The data from this study suggest that a high level of mycelial incompatibility exists among strains of S. sclerotiorum, comparable to levels of vegetative incompatibility reported in other ascomycetes, that the extent of my celial incomp compatibility indicates that genetic heterogeneity exists within the species, and that mycelian compatibility/incompatibility reactions may be an effective way of categorizing intraspecific heterogeneity.

Endophytische Pilze in Blättern und Ästen gesunder und geschädigter Buchen (Fagus sylvatica L.)
Endophytic fungi in leaves and twigs of healthy and diseased beech trees (Fagus sylvatica L.) were isolated and it has been hypothesized, that less capacity of water and nutrient uptake of diseased trees is responsible for this effect. Expand
