1. The self-incompatibility fertilization system in Rosaceae
The Rosaceae include several of the most important fruits - apple, pear, peach, apricot, cherry and plum, all of which are cultivated in Upper Galilee in Israel. The Rosaceae are self-incompatible and, therefore, depend on cross-fertilization. We are studying the self-incompatibility mechanism and its impact on horticulture. Molecular research is combined with field experiments in the orchards, combining basic and applied research.
2. A molecular study of the ripening of climacteric fruit in respect to storage.
We are focusing on genes that are affected by the ripening hormone ethylene. A few new candidate genes which are currently examined. We use tomato as our model plant but our aim to apply our findings to fruit.
