- 2018-2021: PhD course in Agricultural, Food and Environmental Science, University of Catania. Research project: “Cisgenesis and genome editing approaches about candidate genes that control qualitative traits in sweet orange fruits”. In the next few years, agriculture will have to deal with new challenges, like the increase of population, global warming and the constitution of new varieties with increased nutraceutical qualities. In the case of citrus, there is a huge interest in anthocyanin and lycopene-pigmented oranges, which are known to contain more antioxidants compared to common ones. In nature, the presence of citrus variety that containing both anthocyanin and lycopene is not reported. The aim of the research is to try to obtain new citrus genotypes with improved health-promoting properties through the coexistence of both pigments using cisgenesis or genome editing approaches. Knowledge on the role of candidate genes controlling anthocyanins and lycopene accumulation represents the preliminary and, at the meantime, crucial step allowing us to apply both advanced technologies. Genes characterized for being the most appropriate will be evaluated using bioinformatics investigations and subsequent quantitative PCR and High Resolution Melting analysis, to assess genes expression and allelic status, respectively. In sweet orange, the Ruby gene, upstream associated with the 3’LTR of TCS1 retrotrasposon, represents nowadays the only candidate fruit-specific gene that controls the anthocyanin production in blood oranges. We propose to use Ruby for performing a potential cisgenic construct and to transform citrus varieties known for naturally containing lycopene in the flesh. Another strategy takes into account the possibility to realize genome editing constructs to edit candidate genes involved in the carotenoid pathway to increase content of lycopene in blood orange varieties. A huge effort will consist in the optimization of regeneration protocols of citrus varieties that will be considered for both cisgenesis and genome editing experiments. Molecular analysis and phenotypic evaluations will be applied to confirm the efficiency of transformation.
