abstract = {The necrotrophic pathogen Sclerotinia sclerotiorum is a
causal agent of rot diseases in sunflower and is described
as one of the most damaging pathogens of cultivated
sunflower. Resistance to this pathogen is found in some
genotypes of wild sunflower in particular characterised by
significantly reduced lesion lengths in capitulum, stems and
leaves. This study was conducted to characterise
transcriptomic alterations during interaction of host and
pathogen in lesion-surrounding areas of the leaf using
differential display RT-PCR and to compare molecular
responses between a resistant and a susceptible genotype.
Leaves were examined during the first stages of pathogenesis
(dpi 2, 3 and 4) after inoculation with S. sclerotiorum. By
means of computational analysis of fluorescently labelled
expression data, expression patterns were evaluated and
significant differentially expressed transcripts were
selected. The expression profile revealed that a response
measured by the number of significant differentially
expressed transcripts differed between the resistant and
susceptible genotype in timing. Nine differentially
expressed transcripts were successfully sequenced of which
two transcripts originated from the mRNA population of the
pathogen, two transcripts were derived from the susceptible
cultivar of Helianthus annuus and five transcripts were
isolated from the resistant genotype of Helianthus
maximiliani. Semi-quantitative real-time PCR was
accomplished to verify the significant differential
expression of the potentially resistance-associated
transcripts coumarate-CoA-ligase and cysteine protease
transcript in the resistant H. maximiliani accession and
differential expression of a chlorophyll-a/b-binding-protein
and an S-adenosyl-methionine-synthetase transcript
originating from the susceptible H. annuus cultivar.},
