title: Stimulated accumulation of lectin mRNA and stress response in Helianthus tuberosus callus by methyl jasmonate.
abstract: Callus from Helianthus tuberosus expresses a mannose-specific lectin (HTA). The level of HTA mRNA significantly increased one hour after treatment of the callus with 20 mg/l methyl jasmonate. Following this, fragmentation of the callus DNA at regular intervals was observed together with strong self-fluorescence emission in the callus cells.
