Comparative study of the SBP-box gene family in rice siblings.

SBP-box genes are a class of plant-specific transcription factors which have a common DNA-binding domain (SBP-domain) with an unusual zinc-finger architecture. Many of the genes in this class are thought to play a developmental role and a few are involved in the determination of plant architecture. We have made a comparative study of these genes in the genomes of rice ( and ) and its nine siblings using a recently proposed hybrid method for orthology and paralogy detection (HyPPO).
