Gene Details:
- MSU gene ID: LOC_Os11g19060
- RAPdb gene ID: Os11g0295900
- Gene Symbol: BBM1 OsASGR-BBML1 OsBBM1
- Genome: MSU7 , IRGSP-1.0
- Species: Oryza sativa
Functional Descriptions:
- When genome editing to substitute mitosis for meiosis (MiMe)3,4 is combined with the expression of BBM1 in the egg cell, clonal progeny can be obtained that retain genome-wide parental heterozygosity.
- In addition, the suppression of the function of OsASGR-BBML1 and its homologues in zygotes resulted in the developmental arrest, suggesting that OsASGR-BBML1 possesses an important role in initiating zygotic development.
- Interestingly, ectopic expression of OsASGR-BBML1 in egg cells induced nuclear and cell divisions, indicating that exogenously expressed OsASGR-BBML1 converts the proliferation status of the egg cell from quiescent to active.
- We identify OsYUCCA (OsYUC) auxin biosynthesis genes as direct targets of OsBBM1.
- In somatic embryogenesis, exogenous auxin triggers OsBBM1 expression, which then activates endogenous auxin biosynthesis OsYUC genes.
- We used gene editing, transcriptome profiling, and chromatin immunoprecipitation to determine the molecular players involved in embryo initiation downstream of OsBBM1.
- Zygotic embryo initiation involves a partnership of male and female genomes, through which paternal OsBBM1 activates maternal OsYUC genes.
- Ectopic OsBBM1 initiates somatic embryogenesis without exogenous auxins but requires functional OsYUC genes.
