Protein function
Encodes a glycin-rich protein upregulated in response to cold.
Phenotype
Overexpressor: CSP2 overexpressor is late flowering under LD conditions. No data available under SD conditions.
[Sasaki et al., 2013] Single mutant: csp2 single mutant does not display any flowering-time phenotype.
[Sasaki et al., 2013] RNA interference: RNAi donwregulation of
CSP2 expression leads to early flowering under SD conditions. No data available under LD conditions.
[Fusaro et al., 2007] Remarks: The induction of flowering by a LD treatment performed on SD-grown plants leads to an increased expression of all
CSP genes.
[Nakaminami et al., 2009] Function:Chaperone that binds to RNA, single- (ssDNA) and double-stranded (dsDNA) DNA, and unwinds nucleic acid duplex. Accelerates seed germination and seedling growth under cold stress, and contributes to enhancement of cold and freezing tolerance. Regulates flowering transition, and flower and seed development. Promotes seed germination under salt stress. May regulate respiratory oxygen uptake.
