Sažetak
Chloroplast Sensor Kinase (CSK) is a conserved redox sensor kinase, which has been shown to be required for the plastoquinone redox-state dependent regulation of chloroplast reaction centre gene transcription. CSK shows similarity to bacterial family of two-component signalling proteins. The functional partner of CSK in plants and green algae is not a response regulator as in canonical bacterial two-component systems, but an eukaryotic serine/threonine protein kinase known as Plastid Transcription Kinase (PTK) and a chloroplast sigma factor (SIG1). We have generated transgenic Arabidiopsis plants overexpressing CSK tagged with the HA and FLAG peptides. CSK-HA-FLAG plants accumulate tagged CSK in chloroplast stroma which corroborates its possible role in regulation of chloroplast gene expression. In moderate light conditions, CSK-HA-FLAG plants have long leaf petioles and resemble plants grown in low-light or light I conditions. We propose that overexpression of CSK alters redox-dependent regulation of chloroplast origin and reveals novel pathway in plant photomorphogenesis.
