Molecular and phenotypic characterisation of French isolates of Diaporthe helianthi / Phomopsis helianthi Munt.-Cvet
Among a French collection of 150 Diaporthe helianthi / Phomopsis helianthi Munt.-Cvet. isolates collected on sunflower since 1995, 4 were chosen for their different characteristics according to their geographic origin and the part of the infected plant where they were sampled (leaf, petiole, capitulum). Phenotypic and molecular characterisation studies were conducted on these isolates. Phenotyp...
متن کاملChemical characterization of bioactive compounds from the endophytic fungus Diaporthe helianthi isolated from Luehea divaricata
Endophytic microorganisms, defined as fungi or bacteria that colonize the interior of plants without causing any immediate negative effects or damages, have reciprocal relationships with host plants. In some cases their presence is beneficial to the host due to the synthesis of bioactive compounds, among which several alcohols, esters, ketones and others that may react with other compounds and ...
متن کاملAnalyses of QTL associated with resistance to Sclerotinia sclerotiorum and Diaporthe helianthi in sunflower (Helianthus annuus L.) using molecular markers
Most traits exhibit continuous variation resulting from the action of multiple genes modified by the environment. Quantitative trait loci (QTL) analysis consists in determining the location and number of genes that condition such quantitative traits and estimating the magnitude of individual gene effect by the use of analytical methods and detailed linkage map. Sclerotinia sclerotiorum and Diap...
متن کاملDraft whole-genome sequence of the Diaporthe helianthi 7/96 strain, causal agent of sunflower stem canker
Diaporthe helianthi is a fungus pathogenic to sunflower. Virulent strains of this fungus cause stem canker with important yield losses and reduction of oil content. Here we present the first draft whole-genome sequence of the highly virulent isolate D. helianthi strain 7/96, thus providing a useful platform for future research on stem canker of sunflower and fungal genomics. The genome sequence...
متن کاملStem cankers on sunflower (Helianthus annuus) in Australia reveal a complex of pathogenic Diaporthe (Phomopsis) species
The identification of Diaporthe (anamorph Phomopsis) species associated with stem canker of sunflower (Helianthus annuus) in Australia was studied using morphology, DNA sequence analysis and pathology. Phylogenetic analysis revealed three clades that did not correspond with known taxa, and these are believed to represent novel species. Diaporthe gulyae sp. nov. is described for isolates that ca...
