Abstract Expression of two plant chitinase genes, representing members of class III chitinases, was studied in Quercus robur roots during interactions in a pre-mycorrhizal stage with the ectomycorrhizal fungus Piloderma croceum. Chitinase gene expression was compared in lateral roots destined to form ectomycorrhiza, and in principal roots that are not directly involved in mycorrhizal interactions. The transcript level of the first chitinase (QrchitIII-1) was upregulated in lateral roots, whereas no significant differential expression was observed in principal roots. The second chitinase (QrchitIII-2) was regulated neither in lateral nor in principal roots in presence of the fungus. Because P. croceum did not induce significant chitinase responses in principal roots, the enhanced expression of QrchitIII-1 in lateral roots after inoculation may be related to some steps in symbiosis ontogenesis.
