| an intron in the cytochrome b gene of monilinia fructicola mitigates the risk of resistance development to qoi fungicides. | the cytochrome b (cyt b) gene is a key genetic determinant for quinone outside inhibitor (qoi) fungicide resistance in plant pathogenic fungi. a mutation at amino acid position g143 can cause qualitative resistance unless it is part of the recognition site for a self-splicing intron. the objective of this study was to clone and sequence the cyt b gene from monilinia fructicola (wint.) honey, the causal agent of brown rot of stone fruits, and to assess the risk for the development of a mutation a ... | 2010 | 20814880 |
| variations in sequence and occurrence of ssu rdna group i introns in monilinia fructicola isolates. | a group i intron of 418 base pairs in the monilinia fructicola ribosomal small-subunit sequence was characterized. the absence of such an intron in m. laxa and m. fructigena led to a pcr test for m. fructicola identification based on the presence of this intron. the failure to amplify a pcr fragment for some isolates of m. fructicola recently lead to speculation that the intron might not be present always in m. fructicola. in this study, we analyzed 13 isolates of m. fructicola and found that th ... | 2004 | 21148851 |
| evaluation of commercial essential oil samples on the growth of postharvest pathogen monilinia fructicola (g. winter) honey. | to assess the effect of several commercial essential oils samples australian lemon myrtle (backhousia citriodora), cinnamon bark (cinnamomum zeylanicum), oregano (origanum vulgare), thyme oil (thymus vulgaris), clove bud (eugenia caryophyllata), valerian (valeriana officinalis) and australian tea tree oil (melaleuca alternifolia) on mycelium growth and spore germination of monilinia fructicola. the effectiveness of lemon myrtle essential oil as a fumigant for the control of brown rot in nectarin ... | 2011 | 21294758 |
| functions of lipopeptides bacillomycin d and fengycin in antagonism of bacillus amyloliquefaciens c06 towards monilinia fructicola. | in previous studies, bacillus amyloliquefaciens c06 has been proven to be effective in controlling brown rot of stone fruit caused by monilinia fructicola. when tested in vitro, cell-free filtrate of b. amyloliquefaciens c06 significantly inhibited mycelial growth and conidial germination of the fungal pathogen. this study aimed to determine the role of the antifungal compound(s) in the cell-free filtrate of b. amyloliquefaciens c06 by an approach combining a dna-based suppression subtractive hy ... | 2011 | 21335978 |
| prunus domestica pathogenesis-related protein-5 activates the defense response pathway and enhances the resistance to fungal infection. | pathogenesis-related protein-5 (pr-5) has been implicated in plant disease resistance and its antifungal activity has been demonstrated in some fruit species. however, their roles, especially their interactions with the other defense responses in plant cells, are still not fully understood. in this study, we have cloned and characterized a new pr-5 cdna named pdpr5-1 from the european plum (prunus domestica). expression of pdpr5-1 was studied in different cultivars varying in resistance to the b ... | 2011 | 21448276 |
| Monilinia species causing brown rot of peach in China. | In this study, 145 peaches and nectarines displaying typical brown rot symptoms were collected from multiple provinces in China. A subsample of 26 single-spore isolates were characterized phylogenetically and morphologically to ascertain species. Phylogenetic analysis of internal transcribed spacer (ITS) regions 1 and 2, glyceraldehyde-3-phosphate dehydrogenase (G3PDH), ß-tubulin (TUB2) revealed the presence of three distinct Monilinia species. These species included Monilinia fructicola, Monili ... | 2011 | 21980371 |
| Endospore production allows using spray-drying as a possible formulation system of the biocontrol agent Bacillus subtilis CPA-8. | The role of endospore production by Bacillus subtilis CPA-8 on survival during spray-drying was investigated by comparison with a non-spore-forming biocontrol agent Pantoea agglomerans CPA-2. Endospore formation promoted heat resistance in CPA-8 depending on growth time (72 h cultures were more resistant than 24 h ones). The survival of CPA-8 and CPA-2 after spray-drying was determined after being grown in optimised media for 24 and 72 h. Spray-dried 72 h CPA-8 had the best survival (32%), while ... | 2011 | 22187082 |
| capillary and gel electromigration techniques and maldi-tof ms--suitable tools for identification of filamentous fungi. | microbial strains are now spreading out of their original geographical areas of incidence and previously adequate morphological identification methods often must be accompanied by a phenotypic characterization for the successful microbial identification. the fungal genus monilinia represents a suitable example. monilinia species represent important fruit pathogens responsible for major losses in fruit production. four closely related spp. of monilinia: monilinia laxa, monilinia fructigena, monil ... | 2011 | 22284891 |
| genetic diversity of populations of monilinia fructicola (fungi, ascomycota, helotiales) from china. | the genetic variation among 128 isolates of monilinia fructicola (fungi, ascomycota, helotiales) from china was analyzed using inter-simple sequence repeat (issr) markers and compared with those of samples from california, usa and new zealand. a total of 72 reproducible dna fragments were scored, of which 87.5% (63/72) were polymorphic. the nei's gene diversity and shannon's diversity indices of three chinese regional populations were very similar to that from california. however, several differ ... | 2010 | 20113378 |
| the cytochrome p450 lanosterol 14alpha-demethylase gene is a demethylation inhibitor fungicide resistance determinant in monilinia fructicola field isolates from georgia. | resistance in monilinia fructicola to demethylation inhibitor (dmi) fungicides is beginning to emerge in north america, but its molecular basis is unknown. two potential genetic determinants of dmi fungicide resistance including the 14alpha-demethylase gene (mfcyp51) and the atp-binding cassette transporter gene mfabc1, were investigated in six resistant (dmi-r) and six sensitive (dmi-s) field isolates. no point mutations leading to an amino acid change were found in the mfcyp51 gene. the consti ... | 2008 | 18024679 |
| affinity purification and characterization of a cutinase from the fungal plant pathogen monilinia fructicola (wint.) honey. | trifluoromethyl ketones (tfk) are potent inhibitors of a variety of serine hydrolases. the tfk inhibitor, 3-(4-mercaptobutylthio)-1,1,1-trifluoro-2-propanone (mbtfp), was found to competitively inhibit cutinase activity (i50 = 9.4 x 10(-3)) from the fungal plant pathogen monilinia fructicola and to serve as an effective affinity ligand for the purification of cutinases from culture filtrates. the tfk inhibitors, 3-n-octylthio-1,1,1-trifluoro-2-propanone (otfp) and 3-n-pentylthio-1,1,1-trifluoro- ... | 2000 | 11051094 |

| yeasts associated with nectarines and their potential for biological control of brown rot. | resident fruit microflora has been the source of biocontrol agents for the control of postharvest decay of fruits and the active ingredient in commercialized biocontrol products. with the exception of grapes and apples, information on the resident microflora of other fruits is only fragmentary, but greater knowledge in this area can be very helpful in developing biocontrol strategies. we characterized the yeast microflora of nectarines ('croce del sud') from the early stages of fruit development ... | 2010 | 20225339 |
