“…Modern methods of biotechnology and genetic engineering make it possible to accelerate significantly the creation of PPV-resistant high-yield cultivars of stone fruit crops, including apricot (Gentile;Monticelli;Damiano, 2002;Ilardi;Tavazza, 2015;Mitrofanova et al, 2015Mitrofanova et al, , 2017Mitrofanova et al,. 2016;Mourenets;Dolgov, 2016;Rubio et al, 2018). The establishment of an effective genetic transformation system depends on the availability and reliability of the developed regeneration systems via somatic tissues culture.…”
