Annotated Information
Gene Symbol
- Os07g0129700 <=> OSH15,H15
Function
- Homeobox genes encode a large family of homeodomain proteins that play a key role in the pattern formation of animal embryos.
- By analogy, homeobox genes in plants are thought to mediate important processes in their embryogenesis.
Phenotypic analysis
- Over-expression of OSH15 and OSH71 Induces Ectopic Meristems on Leaf Sheaths.
- Over-expression of OSH6 and OSH43 Induces Ligule Displacement in Transgenic Plants.
Knowledge Extension
- Plant homeobox genes can be classified into 14 evolutionary classes, each characterised by fusion of the homeodomain with class‐specific codomains.
- Among these classes only BEL and KNOX are found in red algae, whereas unicellular green algae also include members of the classes WOX, DDT and PINTOX.
- All 14 classes are found only in land plants, including moss and vascular plants, suggesting that homeobox genes have proliferated within each class particularly in flowering plants, indicating that all classes had already differentiated in the common ancestor of moss and vascular plants [2].

Many homeobox genes encode transcription factors with regulatory roles in animal and plant development. Homeobox genes are found in almost all eukaryotes, and have diversified into 11 gene classes and over 100 gene families in animal evolution, and 10 to 14 gene classes in plants. The largest group in animals is the ANTP class which includes the well-known Hox genes, plus other genes implicated in development including ParaHox (Cdx, Xlox, Gsx), Evx, Dlx, En, NK4, NK3, Msx, and Nanog.
