Abstract

A cDNA library from tomato planta macho viroid (TPMV)-infected tomato was constructed. The library was screened at low stringency with a tobacco PR-R cDNA probe. An 832 bp cDNA from a mRNA present only in infected tissue was isolated. Nucleotide sequence showed high homology with the osmotin from both tobacco and tomato (NP24). This cDNA probably corresponds to the AP24 and P23 proteins previously described in tomato and induced upon fungal and viroid infection.
