Discula umbrinella, a fungal endophyte of oak species, colonizes and reproduces on leaves of Quercus alba and Q. rubra in forest ecosystems. Twenty-nine isolates collected from leaves of both oak species (16 from Q. alba and 13 from Q. rubra) were assayed for oak species preference and genetic variation based on primer-specific polymerase chain reactions for the intergenic spacer region (IGS) of ribosomal DNA. DNA sequencing of the polymerase chain reaction products revealed a 10-bp insertion… Expand
Culturable Endophytes Diversity Isolated from Paeonia ostii and the Genetic Basis for Their Bioactivity
TLDR
The results suggest that endophytes isolated from P. ostii had abundant population diversity and biosynthetic potential, which further proved thatendophytes are valuable reservoirs of novel bioactive compounds. Expand
Seasonal deviation effects foliar endophyte assemblage and diversity in Asparagus racemosus and Hemidesmus indicus
TLDR
September–November season proved to be the optimal season for endophyte isolation in both the study plants and assessing the bioactive potential of these endophytes, may lead to the isolation of novel natural products and metabolites. Expand
The Diversity of Root-Associated Endophytic Fungi from Four Epiphytic Orchids in China
TLDR
The diversity of RAF was examined in four wild epiphytic orchids, Acampe rigida, Doritis pulcherrima, Renanthera coccinea, and Robiquetia succisa, that occur in southern China, using a culture-independent method and an in vitro culture method to identify culturable fungi. Expand
Isolation and identification of endophytic fungi from Urginea indica, a medicinal plant from diverse regions of south India.
TLDR
The present study provided a clue that the existence of endophytic fungi in U. indica is known and it can be of great importance if further studies conducted on to elucidate their role in the host plant and for bio-prospecting. Expand
Enzyme inhibitory metabolites from endophytic Penicillium citrinum isolated from Boswellia sacra
TLDR
The results suggest that the endophytic microorganism associated with the arid-land tree can offer a rich source of biologically active chemical constituents that could help discover lead drugs for enzyme inhibition. Expand
Diversity and Ecology of Endophytic and Epiphytic Fungi of Tree Leaves in Japan: A Review
TLDR
This chapter, I summarize studies on the diversity and ecology of endophytic and epiphytic phyllosphere fungi on live leaves of trees in Japan and focuses on the infection and colonization of leaves. Expand
Botryosphaeriaceae species overlap on four unrelated, native South African hosts.
TLDR
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.

AN INVESTIGATION OF BIODIVERSITY OF ENDOPHYTIC FUNGI ASSOCIATED WITH SOME MEDICINAL PLANTS
TLDR
Traditional medicinal plants are a rich and reliable source of novel endophytic fungi, and the first step towards understanding host-endophyte relationships based on the plant chemistry is taken. Expand

Intraspecific variation within populations of Fusarium oxysporum based on RFLP analysis of the intergenic spacer region of the rDNA.
TLDR
Overall, the IGS haplotype was more variable among the nonpathogenic F. oxysporum VCGs among which 12 of the 13 I GS haplotypes were found, and among most F. o. Expand
Relationships among pathogenic and nonpathogenic isolates of Fusarium oxysporum based on the partial sequence of the intergenic spacer region of the ribosomal DNA.
TLDR
Nonpathogens and pathogens may share common alleles at vegetative compatibility loci by coincidence rather than because of recent clonal derivation from a common ancestor. Expand
Differentiation of isolates of Discula umbrinella (Teleomorph: Apiognomonia errabunda) from beech, chestnut, and oak using randomly amplified polymorphic DNA markers.
TLDR
Cluster analysis of all arbitrary primed amplified DNA fragments showed that the isolates could be placed into four groups corresponding to their host origin, and the high percentage of private RAPD variants within groups is consistent with low gene flow. Expand
Endophytic-Host Selectivity of Discula umbrinella on Quercus alba and Quercus rubra Characterized by Infection, Pathogenicity and Mycelial Compatibility
TLDR
The results of this study suggest that the endophyte–host relationship is one of host selective preference for Q. alba, but that theendophyte has the ability to maintain the endophtic/pathogenic life cycle on the less preferred host species, Q. rubra. Expand
