Accumulation of Phenolic Compounds in Conifer Callus Cultures in Response to Wood Blue-Stain Fungi

Accumulation of Phenolic Compounds in Conifer Callus Cultures in Response to Wood Blue-Stain Fungi Callus cultures of Siberian larch (Larix sibiricaLedeb.) and Siberian spruce (Picea obovataLedeb.) were used to demonstrate the elicitor activity of two ophiostomatoid fungal species, Ceratocystis laricicolaand Ceratocystis polonica, as the pioneer settlers on larch and spruce, respectively.

Abstract

Callus cultures of Siberian larch (Larix sibiricaLedeb.) and Siberian spruce (Picea obovataLedeb.) were used to demonstrate the elicitor activity of two ophiostomatoid fungal species, Ceratocystis laricicolaand Ceratocystis polonica, as the pioneer settlers on larch and spruce, respectively. The extract from C. laricicolamycelium stimulated the accumulation of lignin in larch cells by 37% and that of bound proanthocyanidins by 25%. In spruce callus cultures, C. laricicolaand C. polonicaincreased the bound PA content by 25 and 46%, respectively. In the callus cultures of larch and spruce, the addition of extract of C. laricicolaincreased the concentration of p-hydroxybenzoic acid 13-fold and nearly 4-fold, respectively. The metabolic characteristics of accumulation of phenolic compounds in conifer cells are discussed.
