Reversion/recovery

Topic:

Pathology

Definition:

“1) “”…when cuttings obtained from diseased plants are propagated, some grow into symptomless virus-free plants (Cours, 1951). This phenomenon is referred as `reversion’ (Pacumbaba, 1985), `self-elimination’ (Rossel et al., 1988) or `recovery’ (Fargette et al., 1996) in cassava, and similar behaviour has also been reported with other vegetatively propagated crops including potato.””

2) “”…the ability of plants that are virus-infected to become at least mostly virus-free”””
