| Research Abstract |
We investigated the possible involvement of Arabidopsis Ca^<2+>-dependent protein kinases (CPKs) and their substrates in the herbivory- or abiotic stress-induced signaling network for the defense-related transcriptional machinery. We found that CPK-derived phosphorylation of a heat shock transcription factor (HsfB2a) promotes transcriptional activation in the defense response. Those CPKs are likely to contribute to a wide range of central signal transduction responses in plants, whereas their substrate targets are differently involved.
