Annotated Information
OsMYBS3 is a single DNA-binding repeat MYB transcription factor to mediate sugar signaling and plays a critical role in cold adaptation in rice.
Function
OsMYBS3 acts as a repressor, in sugar starvation–induced α-amylase gene expression. As a repressor, whether OsMYBS3 plays a negative role in the sugar regulation ofα-amylase gene expression is not clear. OsMYBS3 is most abundant in senescent leaves, in which sugars are depleted as a result of their transport to other tissues. OsMYBS3 may preventα-amylase genes from being induced by the low sugar level in senescent leaves, which would be a wasteful process in dying cells [1].
Expression
The open reading frames of OsMYBS1, OsMYBS2, and OsMYBS3 encode polypeptides of 306, 276, and 318 amino acid residues, respectively. The three OsMYBSs contain a highly conserved single DNA binding domain that is very similar to the DNA binding domains of other mammalian, Drosophila, and plant. OsMYBS3 is expressed in all tissues, with the highest level in senescent leaves. The levels of OsMYBS3 mRNAs are low in the presence of Suc but increase in the absence of Suc which were parallel to the mRNA levels of α-Amy3 and another rice α-amylase gene, α-Amy8. OsMYBS3 is suppressed in the presence of Glc or GA but remains unchanged in the presence of abscisic acid. OsMYBS3 doesn't significantly enhance luciferase activity in the presence of Glc and repressed luciferase activity in the absence of Glc. OsMYBS3 may serve as a repressor, for transcription of the promoter containing SRS [1]. OsMYBS3 in rice are enhanced by ABA and abiotic stresses [2] and cold stress conditions [3], respectively.In addition, OsMYBS3 in rice regulates the expression of cold-related genes such as WRKY77 and Glu decarboxylase, both of which contain a TATCCA element in their promoters [3].
Evolution
OsMYBS3 is rich in both Pro (19 of 166 amino acids, or 11%) and acidic amino acids (22 of 166 amino acids, or 13%). It is not clear why OsMYBS2 and OsMYBS3 do not form homodimers by themselves and why the three Os-MYBSs do not form heterodimers with each other [1]. Barley HvMYBS3, rice OsMYBS3 and maize ZmMYBSt1 are probably orthologous, because, in addition to the 100% identity of their DBD, they share 84.6% and 80.9% identical residues, respectively, along their whole protein sequences (WPS) [4].
