文摘
- •
OsCCD1 is a small calcium-binding protein with one EF-hand motif in rice.
- •
OsCCD1 can bind calcium ion in the in vitro EMSA and fluorescence staining calcium-binding assays.
- •
OsCCD1 is localized in the nucleus and cytosol of rice cells.
- •
OsCCD1 transcript levels are transiently induced by osmotic stress, salt stress and calcium-mediated ABA signal.
- •
OsCCD1 can enhance the tolerances to osmotic and salt stress via the enhanced transcription levels of OsDREB2B, OsAPX1 and OsP5CS genes in rice seedlings.
