Molecular Approaches to Disease Resistance in Fragaria SPP.
Resistance to economically important diseases is one of the most desired traits to have in plant crops. The Fragaria genus including 21 wild and cultivated species (Fragaria x ananassa), contains genetic sources of diseases resistance that are quite rich but not fully exploited in breeding for resistance. Usefulness of different molecular techniques and high throughput technologies for the dissection of genetic resistance mechanisms and the explanation of plant diversity in relation to pathogens at the DNA level are described in this paper. The descriptions are based on the results of different studies on genome of Fragaria that were carried out in many research institutions in the world. The proposed model of comprehensive exploration of the strawberry genome, summarized with generating resistance markers and identification of genes involved with induction or regulation of plant response to pathogen attack, appear to be very useful in breeding strawberry for resistance.
