| endopolygalacturonase is essential for citrus black rot caused by alternaria citri but not brown spot caused by alternaria alternata. | alternaria citri, the cause of alternaria black rot, and alternaria alternata rough lemon pathotype, the cause of alternaria brown spot, are morphologically indistinguishable pathogens of citrus: one causes rot by macerating tissues and the other causes necrotic spots by producing a host-selective toxin. to evaluate the role of endopolygalacturonase (endopg) in pathogenicity of these two alternaria spp. pathogens, their genes for endopg were mutated by gene targeting. the endopgs produced by the ... | 2001 | 11386370 |
| fungitoxic activity of 12 essential oils against four postharvest citrus pathogens: chemical analysis of thymus capitatus oil and its effect in subatmospheric pressure conditions. | the fungitoxic activity against penicillium digitatum, penicillium italicum, botrytis cinerea, and alternaria citri of 12 essential oils (eos) distilled from medicinal plants is reported. the results of the in vitro trials show strong fungitoxic activity of thymus capitatus (l.) hofmgg eos, which inhibited the growth of the four fungi at a concentration of 250 ppm (vol/vol). the other 11 essences reduced the development of the fungi from 95 to 9% at 250 ppm (vol/vol). the fungitoxic activity of ... | 2001 | 11456187 |

| antimicrobial activity of extracts of chemical races of the lichen pseudevernia furfuracea and their physodic acid, chloroatranorin, atranorin, and olivetoric acid constituents. | the antimicrobial activity and the mic values of the ethanol, chloroform, diethyl ether, and acetone extracts of the chemical races of pseudevernia furfuracea (var. furfuracea and var. ceratea) and their physodic acid, chloroatranorin, atranorin, and olivetoric acid constituents have been investigated against some microorganisms. nearly all extracts of both chemical races showed antimicrobial activity against aeromonas hydrophila, bacillus cereus, bacillus subtilis, listeria monocytogenes, prote ... | 2006 | 16989308 |
| overexpression of citrus polygalacturonase-inhibiting protein in citrus black rot pathogen alternaria citri. | the rough lemon (citrus jambhiri) gene encoding polygalacturonase-inhibiting protein (rlempgipa) was overexpressed in the pathogenic fungus alternaria citri. the overexpression mutant acopi6 retained the ability to utilize pectin as a sole carbon source, and the overexpression of polygalacturonase-inhibiting protein did not have any effect on the growth of acopi6 in potato dextrose and pectin medium. the pathogenicity of acopi6 to cause a black rot symptom in citrus fruits was also unchanged. po ... | 2007 | 17223223 |
| [study of the effect of volatile metabolites of trichoderma hamatum on the growth of phytopathogenic soilborne fungi.]. | volatile compounds produced by trichoderma hamatum were tested for their capacity to suppress in vitro the growth of alternaria citri, bipolaris cynodontis, bipolaris sorokiniana, curvularia brachyspora, curvularia lunata, curvularia oryzae-sativae, drechslera tritici-repentis, rhizoctonia solani, sclerotinia minor and sclerotium rolfsii. the organisms were cultured in an apparatus made with two erlenmeyer flasks assembled by their top parts. with the aid of the gas chromatographic technique the ... | 1997 | 17655390 |
| fungal flora in indoor and outdoor air of different residential houses in tekirdag city (turkey): seasonal distribution and relationship with climatic factors. | this study was investigated the density and monthly distribution of indoor and outdoor microfungi in six different residential houses in tekirdag city through the exposure of petri dishes containing rose-bengal streptomycin agar media. samples were collected in 1-month intervals over a period of 12 months between march, 2001, and february, 2002. we used 432 petri dishes and counted a total of 4,205 microfungi colonies, 1,790 from indoor air and 2,415 from outdoor air. as a result, 42 species bel ... | 2009 | 18509736 |
| green fluorescent detection of fungal colonization and endopolygalacturonase gene expression in the interaction of alternaria citri with citrus. | abstract alternaria citri, a postharvest pathogen, produces endopolygalacturonase (endopg) and causes black rot on citrus fruit. we previously described that an endopg-disrupted mutant of alternaria citri was significantly reduced in its ability to macerate plant tissue and cause black rot symptoms on citrus. in order to investigate colonization of citrus fruit tissues by alternaria citri, ptefegfp carrying a green fluorescent protein (gfp) gene was introduced into wild-type alternaria citri and ... | 2003 | 18943156 |
| molecular systematics of citrus-associated alternaria species. | the causal agents of alternaria brown spot of tangerines and tangerine hybrids, alternaria leaf spot of rough lemon and alternaria black rot of citrus historically have been referred to as alternaria citri or a. alternata. ten species of alternaria recently were described among a set of isolates from leaf lesions on rough lemon (citrus jambhiri) and tangelo (c. paradisi × c. reticulata), and none of these isolates was considered representative of a. alternata or a. citri. to test the hypothesis ... | 2004 | 21148834 |
| airborne and soilborne microfungi in the vicinity hamitabat thermic power plant in kirklareli city (turkey), their seasonal distributions and relations with climatological factors. | soil and air samples of seven different localities around hamitabat thermic power plant, 10 km far away from luleburgaz/kirklareli (turkey), were taken between the years 2003 and 2004 with seasonal intervals. the samples were brought to the laboratory and their microfungal identifications were done. from the air samples, 737 microfungi colonies were isolated comprising 26 species belonging to eight genera. from soil samples, 170.6 x 10(4) colony-forming unit (cfu)/g was isolated from 33 species ... | 2010 | 19347592 |
| a virulence-reducing mutation in the postharvest citrus pathogen alternaria citri. | abstract alternaria citri causes alternaria black rot, a postharvest fruit disease, on a broad range of citrus cultivars. we previously described that an endopolygalacturonase minus mutant of a. citri caused significantly less black rot in citrus fruit. to search for other essential factors causing symptoms in addition to endopolygalacturonase, a random mutation analysis of pathogenicity was performed using restriction enzyme-mediated integration. three isolates among 1,694 transformants of a. c ... | 2006 | 18944048 |
| overexpression of a gene encoding a catabolite repression element in alternaria citri causes severe symptoms of black rot in citrus fruit. | abstract a gene (accrea) encoding a catabolite repression element (crea) with (two zinc fingers of the cys(2)his(2) type was isolated from the postharvest fungal pathogen alternaria citri. the accrea overexpression mutant acoec2 of a. citri showed normal growth on pectin medium and on segments of peel or the juice sac area from citrus fruit. production of endopolygalacturonase, an essential virulence factor of this pathogen, was similar in acoec2 and the wild type in pectin-containing media. how ... | 2007 | 18943574 |
| characterization of cdnas encoding two distinct miraculin-like proteins and stress-related modulation of the corresponding mrnas in citrus jambhiri lush. | two distinct full-length cdnas from rough lemon that encoded miraculin-like proteins were isolated by random amplification of cdna ends (races), based on sequence information from subtractive pcr previously described, and designated as rlemmlp1 and rlemmlp2. the transcripts of both rlemmlp1 and rlemmlp2 were not detected in leaves, or stems but accumulated in fruits. transcripts accumulated to higher levels in leaves after wounding, inoculation with conidia of alternaria alternata, or treatment ... | 2006 | 16463104 |
| cyclopenta[b]benzofurans from aglaia species with pronounced antifungal activity against rice blast fungus (pyricularia grisea). | eight flavaglines, six cyclopenta[b]benzofurans, a cyclopenta[bc]benzopyran, and a benzo[b]oxepine, together with an aromatic butyrolactone were isolated from aglaia odorata, a. elaeagnoidea, and a. edulis (meliaceae) and tested against the three plant pathogens pyricularia grisea, fusarium avenaceum, and alternaria citri for antifungal properties. using the microdilution technique linked with digital image analysis of germ tubes, the benzofurans displayed strong activity, whereas the benzopyran ... | 2000 | 10775404 |
