چکیده انگلیسی
A study on the representation of Aspergillus carbonarius in the vineyards of the Mesogeia geographical region of Attica, Greece, was conducted. One hundred and twenty five samples of the indigenous drought and disease resistant Savatiano wine grape variety, the most widely planted in Greece, were collected. The sample's total DNA extracts were initially tested for fungal DNA presence by targeting the Internal Transcribed Spacer (ITS) region in end-point Polymerase Chain Reactions. Samples which were proved positive were further subjected to PCR analysis using specific primers targeting an A. carbonarius polycetide synthase (pks) gene. Among ITS positive samples (70%), A. carbonarius was represented in 42% of them. Furthermore, a SYBR Green I Real Time PCR method was used to quantify the amount of this species in the grape samples. The values of the positive samples were estimated in the range of 13 to 50 Ã 103 fungal haploid genomes/g grapes. The significance of this study lies in the applicability of a rapid and culture-independent method to detect and quantify A. carbonarius on grapes.
