Abstract Intercellular fluid (IF) extracted from the apoplastic leaf spaces of Petunia contained up to 6 new soluble proteins, called d proteins (d 0 to d 5 ). Characterisation of the d proteins has shown that they can be divided into groups and show a genetic variability similar to the PR(b) proteins from Nicotiana. d protein patterns from Petunia interspecific hybrids clearly show that the determinant for the d proteins in sexually transmitted as is the case for b proteins in Nicotiana. d‐protein induction in TMV‐SM 1 infected Petunia leaves is discussed in relation to the resistance to infection shown by cultivars and hybrids of Petunia.
