Abstract
Conditions of environmental stress may lead to epigenetic variability in plants. In particular, variation in genome methylation may be a mechanism of plant adaptation to abiotic stresses. We have investigated the relationship between water deficit and DNA changes in specific sequences by using the CRED-RA (Coupled Restriction Enzyme Digestion and Random Amplification) approach. Three polymorphic bands have been detected in dehydrated and rehydrated pea root tips. One of these bands is a zinc-finger sequence with three non canonical motifs, that could be involved in signal transduction pathways
