The rice Os01g0104100 was reported as OsCOIN in 2007 [1] by researchers from China.

Gene Symbol

  • Os01g0104100 <=> OsCOIN,COIN


  • The rice OsCOIN encodes a putative RING finger protein.
  • OsCOIN (Oryza sativa cold-inducible) is a novel cold-inducible gene in rice. It can increase tolerance to chilling, salt and drought, and enhance proline level in rice.

Phenotypic analysis

  • 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.


  • OsCOIN is expressed in all rice organs and strongly induced by low temperature, ABA, salt and drought.

Subcellular localization

  • The subcellular localization analysis showed that OsCOIN is localized in both nuclear and cytoplasm membrane
