Gene Symbol
- Os01g0928000 <=> ICE2, OsICE2, OsbHLH001
Function
- OsICE OsbHLH001/OsICE2 and OsbHLH002/OsICE1 function in regulating OsDREB1B and OsHsfA3 involved in cold acclimation and trehalose synthesis[1][2].
GO assignment(s): GO:0005634, GO:0030528, GO:0045449
Expression
- Chilling stress on rice seedlings induced two ICE-related proteins with molecular masses of approximately 55 and 40 kDa. These sizes are consistent with those predicted for OsICE1 and OsICE2, respectively. In contrast to the proteins, cold stress had little or no effect on the expression of OsICE1 and OsICE2[1].
- Salt stress upregulated levels of OsICE2 protein but had no effect on OsICE2 mRNA levels. RT-PCR revealed that cold stress increased the levels of OsICE1 and OsICE2 proteins but did not enhance the expression of their genes. OsICE1 and OsICE2 are regulated mainly by post-translational mechanisms, in a manner similar to that of Arabidopsis ICE1[1].
Evolution
- A phylogenetic tree of ICE homologs in dicots and monocots, using Arabidopsis PIF3 and human c-myc as outgroups, showed that ICE-related genes can be classified into monocot and dicot subfamilies (Figure 1).
- OsICE1 and OsICE2 share very similar sets of motifs, notably an acidic domain, a Ser-rich domain, a bHLH domain, and a possible zipper region, with Arabidopsis ICE1, although OsICE2 has a shorter junction region between the acidic region and the Ser-rich region in the amino terminus than OsICE1 and Arabidopsis ICE1[1].
- Although OsICE1 and OsICE2 have different predicted molecular masses, they share 48% similarity at the amino acid level. They also have similarities of 39% and 45%, respectively, to Arabidopsis[1].
