Identification and characterization of DNA polymorphisms influencing economically important traits in diploid and polyploid stone fruit trees
Identification and characterization of DNA polymorphisms influencing economically important traits in diploid and polyploid stone fruit trees
This project is focused on three scientific aims: 1) Designing/testing molecular markers associated with economically important traits (e.g. fruit maturity date, self-incompatibility and fruit flesh colour); 2) a detailed analysis of the biological functions of FaSt transposon that was shown to be responsible for self-compatibility in apricot; and 3) working out protocols for molecular cytogenetic studies on European plum genome structure. We check if FaSt transposon is transcribed in specific tissues of apricot and if it has any regulatory role.

Analysis of genes and candidate genes contributing to crop reliability of polyploid Prunus fruit trees
We characterized the S-RNase and SFB genes of the multiallelic S-locus that control the self-(in)compatibility phenotype of sour cherries (tetraploid) and European plums (hexaploid) species. We identified the CBF and DAM genes contributing to the induction and cessation of endodormancy. It was confirmed by their characteristic expression profile over the dormant period. We characterized the DNA sequence of a NAC transcription factor encoding gene of several Prunus species, this gene has been hypothesized to influence fruit maturity date in peaches.

We worked out a protocol for the in vitro micropropagation of a PPV-sensitive ‘Besztercei Bt.2’ and a PPV-tolerant (‘Nábrád’ syn. ‘Nemtudom’) European plum cultivar. We have sequenced an isoform of the eukaryotic translation initiation factor, eIF(iso)4E gene, encoding for a host susceptibility factor required for PPV infection in plum. We detected the genetic differentiation of the two Hungarian landraces and also showed genetic variations within the ‘Nemtudom’ germplasm. Our results will help both conventional and molecular breeding of the studied and other European plum cultivars.
