Gene Symbol
- Os03g0727000 <=> OSKN1, Oskn1, OsKN1, OSH1/Oskn1, HB75
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.
- OSH1 is not directly associated with organ differentiation, but may be related to a regulatory process before or independent of the organ determination.
- OSH1 plays an important role in regionalization of cell identity during early embryogenesis.
Expression
- In situ hybridization analysis revealed that in the wild-type embryo, OSH1 was first expressed at the globular stage, much earlier than organogenesis started, in a ventral region where shoot apical meristem and epiblast would later develop.
- This localized expression of OSH1 indicates that the cellular differentiation has already occurred at this stage.
- At later stages after organogenesis had initiated, OSH1 expression was observed in shoot apical meristem [except in the Li (tunica) layer], epiblast, radicle, and their intervening tissues in descending strength of expression level with embryonic maturation.
