title: Overexpression of OsCOIN, a putative cold inducible zinc finger protein, increased tolerance to chilling, salt and drought, and enhanced proline level in rice.
abstract: Rice (Oryza sativa L.) plant is sensitive to chilling, particularly at early stages of seedling development. Here a novel cold-inducible gene, designated OsCOIN (Oryza sativa cold-inducible), was isolated and characterized. Results showed that OsCOIN protein, a RING finger protein, was localized in both nuclear and cytoplasm membrane. OsCOIN is expressed in all rice organs and strongly induced by low temperature, ABA, salt and drought. Over-expression of OsCOIN in transgenic rice lines significantly enhanced their tolerance to cold, salt and drought, accompanied by an up-regulation of OsP5CS expression and an increase of cellular proline level.
