| endophytic fungi from vitis labrusca l. ('niagara rosada') and its potential for the biological control of fusarium oxysporum. | we investigated the diversity of endophytic fungi found on grape (vitis labrusca cv. niagara rosada) leaves collected from salesópolis, sp, brazil. the fungi were isolated and characterized by amplified ribosomal dna restriction analysis, followed by sequencing of the its1-5.8s-its2 rdna. in addition, the ability of these endophytic fungi to inhibit the grapevine pathogen fusarium oxysporum f. sp herbemontis was determined in vitro. we also observed that the climatic factors, such as temperature ... | 2012 | 23315803 |
| Endophytic and pathogenic Phyllosticta species, with reference to those associated with Citrus Black Spot. | We investigated the identity and genetic diversity of more than 100 isolates belonging to Phyllosticta (teleomorph Guignardia), with particular emphasis on Phyllosticta citricarpa and Guignardia mangiferae s.l. occurring on Citrus. Phyllosticta citricarpa is the causal agent of Citrus Black Spot and is subject to phytosanitary legislation in the EU. This species is frequently confused with a taxon generally referred to as G. mangiferae, the presumed teleomorph of P. capitalensis, which is a non- ... | 2011 | 22025803 |
| enzymatic differences between the endophyte guignardia mangiferae (botryosphaeriaceae) and the citrus pathogen g. citricarpa. | the endophyte guignardia mangiferae is closely related to g. citricarpa, the causal agent of citrus black spot; for many years these species had been confused with each other. the development of molecular analytical methods has allowed differentiation of the pathogen g. citricarpa from the endophyte g. mangiferae, but the physiological traits associated with pathogenicity were not described. we examined genetic and enzymatic characteristics of guignardia spp strains; g. citricarpa produces signi ... | 2011 | 21341216 |
| endophytic fungi from leaves of centella asiatica: occurrence and potential interactions within leaves. | fungal endophytes were isolated from leaves of centella asiatica (apiaceae) collected at mangoro (middle eastern region of madagascar, 200 km from antananarivo). forty- five different taxa were recovered. the overall foliar colonization rate was 78%. the most common endophytes were the non-sporulating species 1 (isolation frequency if 19.2%) followed by colletotrichum sp.1 (if 13.2%), guignardia sp. (if 8.5%), glomerella sp. (if 7.7%), an unidentified ascomycete (if 7.2%), the non-sporulating sp ... | 2008 | 17610142 |
| characterization of guignardia mangiferae isolated from tropical plants based on morphology, issr-pcr amplifications and its1-5.8s-its2 sequences. | phenotypic and genotypic variability of 18 endophytic guignardia strains from different host plants (anacardiaceae: anacardium giganteum, myracrodruon urundeuva, spondias mombin; apocynaceae: aspidosperma polyneuron; ericaceae: rhododendron sp.; fabaceae: bowdichia nitida; leguminosae: cassia occidentalis; rutaceae: citrus aurantium) growing in different sites in brazil was assessed by means of morphometric measurements and inter-single-sequence-repeat-anchored polymerase chain reaction (issr-pc ... | 2004 | 15035504 |
| its-rflp and its sequence analysis of a foliar endophytic phyllosticta from different tropical trees. | different isolates of a foliar endophytic species of phyllosticta were isolated from different tropical tree species in india to examine genetic variation among the isolates. internal transcribed spacer-restriction fragment length polymorphism (its-rflp) analysis did not detect any variation among the isolates, suggesting that they all belong to the same species. sequence data of the its region of ribosomal dna (its1 and its2, including 5.8s rdna) supported the identity of the present fungal iso ... | 2003 | 12825516 |
| nonpathogenic isolates of the citrus black spot fungus, guignardia citricarpa, identified as a cosmopolitan endophyte of woody plants, g. mangiferae (phyllosticta capitalensis). | abstract the population structure of guignardia citricarpa sensu lato (anamorph: phyllosticta citricarpa), a fungus of which strains pathogenic to citrus are subject to phytosanitary legislation in the european union and the united states, was investigated. internal transcribed spacer sequences revealed two phylogenetically distinct groups in g. citricarpa. this distinction was supported by amplified fragment length polymorphism analysis that also supported the exclusion of two isolates that had ... | 2002 | 18943020 |
| characterization of the melanin pigment of a cosmopolitan fungal endophyte. | phyllosticta capitalensis (teleomorph guignardia mangiferae) occurs as a foliar endophyte in woody trees belonging to different families of both temperate and tropical regions. we isolated this endophyte from plants in different habitats, such as mangroves, dry deciduous forest, moist deciduous forest and semi-evergreen forest. this endophyte was found to produce a black pigment that was characterized to be melanin based on uv-visible, ir and esr spectra and chemical tests. tricyclazole, a speci ... | 2004 | 15449603 |
