+The rice '''Os07g0549600''' was reported as '''''OsbHLH164''''' in 2006 <ref name="ref1" /> by researchers from the China. It is a member of bHLH transcription factor gene family.
 ==Annotated Information==
 ===Function===
-The tapetum, the innermost of four sporophytic layers in the anther wall, comes in direct contact with the developing male gametophyte and is thought to play a crucial role in the development and maturation of microspores. UDT1 gene is required for the differentiation of secondary parietal cells to mature tapetal cells and plays a major role in maintaining tapetum development, starting in early meiosis. The transcript is preferentially present in all cell types within the early anthers. This gene is a Major Regulator of Early Anther Development and at the molecular level the meiocyte development is regulated by this gene[1].
+* The basic/helix-loop-helix (bHLH) transcription factors and their homologs form a large family in plant and animal genomes.
 ===Expression===
-It encodes a predicted protein of 227 amino acids and the protein has an apparent molecular mass of 24.9 kD and a pI of 6.5[1]. The region between the 59th and 118th amino acids is predicted to be a bHLH domain, possessing both the HLH domain required for dimerization and a nearby basic domain necessary for target DNA binding. The promoter region comprises a putative TATA box sequence at 406 bp upstream from the start ATG codon and a CAAT box sequence at -471. The upstream region also contains putative regulatory sequences: GTGA motifs (GTGA) at -485 and -48, responsible for pollen specificity; E-box sequences (CANNTG) At - 845, - 702, and - 205, where the MYC class transcription factors bind; a MYBCORE motif (CNGTTR) at -238, in which a petunia MYB protein involved in the regulation of flavonoid biosynthesis also binds[2]; and a MYBGA motif (TAACAAA) at - 945, at which GAMYB binds.
+* Similar expression patterns suggest functional conservation between some rice bHLH genes and their close Arabidopsis homologs.
 ===Evolution===
-Please input evolution information here.
+* The studies of researchers indicate that the ancient bHLH gene family has likely expanded considerably during flowering plant evolution to include many relatively young members, allowing both the conservation and divergence of gene function.
 You can also add sub-section(s) at will.
