The gene encoding hordothionin confers resistance to Venturia
inequalis and Nectria galligena. It might also affect Podosphora
leucotricha and Erwinia amylovora.
Since it is at this stage unknown whether there will be any effect
of the modification in relation to sensitivity to other fungal or
bacterial diseases, dispersal or introgression of the trait should
In case of upscaling of the field trials, experimental data should
be supplied regarding the degradation patterns of the hordothionin
proteins in the soil and if this will affect soil organisms.
Furthermore, data may be asked regarding the possible effects of
the GMPs on (visiting) insects.
1. The rootstocks bearing grafts will be harvested in before
sprouting and evaluated under controlled experimental
2. Evaluation of resistance to apple scab (Venturia inequalis) in
the open field;
3. Evaluation of specifity of resistance to other plant-pathogenic
organisms, such as mildew (Podosphora leucotricha) and fruittree
cancer (Erwinia amylovora).
