Differential production of phytotoxins from Phomopsis sp. from grapevine plants showing esca symptoms.
Nine strains of the fungus Phomopsis spp. were isolated from a vineyard showing decline from the disease esca. Strains were screened for their ability to produce secondary metabolites showing chemical diversity. The culture extracts of each strain were analyzed by liquid chromatography-ultraviolet-diode array detection-mass spectrometry. Three strains were selected for the isolation and charact...
متن کاملHigh-Level Culturability of Epiphytic Bacteria and Frequency of Biosurfactant Producers on Leaves.
UNLABELLED To better characterize the bacterial community members capable of biosurfactant production on leaves, we distinguished culturable biosurfactant-producing bacteria from nonproducers and used community sequencing to compare the composition of these distinct cultured populations with that from DNA directly recovered from leaves. Communities on spinach, romaine, and head lettuce leaves w...
متن کاملCharacterization of Epiphytic Bacterial Communities from Grapes, Leaves, Bark and Soil of Grapevine Plants Grown, and Their Relations
Despite its importance in plant health and crop quality, the diversity of epiphytic bacteria on grape berries and other plant parts, like leaves and bark, remains poorly described, as does the role of telluric bacteria in plant colonization. In this study, we compare the bacterial community size and structure in vineyard soils, as well as on grapevine bark, leaves and berries. Analyses of cultu...
متن کاملInfluence of immigration on epiphytic bacterial populations on navel orange leaves.
Factors that influenced the increase in epiphytic bacterial population size on navel orange leaves during winter months were investigated to test the assumption that such populations were the result of multiplication on orange leaves. The population sizes of bacteria of different kinds, including ice nucleation-active (Ice(sup+)) bacteria, were from 6- to 30-fold larger on leaves of navel orang...
متن کاملMetabolic Fingerprint of PS3-Induced Resistance of Grapevine Leaves against Plasmopara viticola Revealed Differences in Elicitor-Triggered Defenses
Induction of plant resistance against pathogens by defense elicitors constitutes an attractive strategy to reduce the use of fungicides in crop protection. However, all elicitors do not systematically confer protection against pathogens. Elicitor-induced resistance (IR) thus merits to be further characterized in order to understand what makes an elicitor efficient. In this study, the oligosacch...
