title: The phylogeny and expression pattern of APETALA2-like genes in rice.
abstract: The multigene families undergo birth-and-death evolution and thus contribute to biological innovations. The APETALA2-like genes belong to the euAP2 group of the AP2 gene family. These genes are characterized by several distinct motifs and exist in ferns, gymnosperms, and angiosperms. The phylogenetic analysis indicated that these genes have undergone the birth-and-death evolution. The five APETALA2-like genes in rice (Oryza sativa L.) display redundant but distinct expression patterns as demonstrated by RT-PCR and in situ hybridization. The potential functions of these genes were discussed on the basis of phylogenetic and expression pattern.
