ABSTRACT
Calcium is a key second messenger in signaling pathways associated with developmental and adaptive processes in plants. Stimulus-specific calcium signals, considered as calcium signatures, are translated into appropriate cellular responses through the action of various calcium-binding proteins and downstream effectors. We review here recent progress made in calcium signaling in the nucleus of plant cell. Experimental evidences show that nuclei can generate calcium signals on their own and point out the importance of calcium in the regulation of gene transcription. Future directions are given concerning the need to elucidate the mechanisms involved in the regulation of nuclear calcium homeostasis, the conversion of calcium signals into transcriptional responses or other fundamental downstream nuclear functions. Overall, a better understanding of nuclear signaling will be useful to get an integrated picture of the signaling network of the plant cell.
