- Genbank accession number
- Key message
- Male semi-sterility in this heterozygous complex locus is caused by abortion of pollen carrying SaM(-)
- Here we show that a locus for indica-japonica hybrid male sterility, Sa, comprises two adjacent genes, SaM and SaF, encoding a small ubiquitin-like modifier E3 ligase-like protein and an F-box protein, respectively
- This allele-specific gamete elimination results from a selective interaction of SaF(+) with SaM(-), a truncated protein, but not with SaM(+) because of the presence of an inhibitory domain, although SaM(+) is required for this male sterility
- Our results firmly proved that SaF and SaM are required for the hybrid male sterility, but are not essential for pollen development
- Here we showed that silencing of SaF or SaM by RNA interference restored male fertility in indica-japonica hybrids with heterozygous Sa

- MOC3~OsWUS~TAB1~OsTAB1, SaM, TILLERS ABSENT1, the WUSCHEL ortholog, is not involved in stem cell maintenance in the shoot apical meristem in rice., We previously showed that, in rice (Oryza sativa), the WUS ortholog TILLERS ABSENT1 (TAB1, also known as OsWUS) has no function in SAM maintenance, whereas it plays a crucial role in axillary meristem development
- MOC3~OsWUS~TAB1~OsTAB1, SaM, TILLERS ABSENT1, the WUSCHEL ortholog, is not involved in stem cell maintenance in the shoot apical meristem in rice., In this paper, we confirmed that TAB1 is also unrelated to the enlargement of the SAM in the vegetative phase of the fon2 and fon2 asp1 mutants
- MOC3~OsWUS~TAB1~OsTAB1, SaM, TILLERS ABSENT1, the WUSCHEL ortholog, is not involved in stem cell maintenance in the shoot apical meristem in rice., In addition, misexpression of TAB1 under the promoter of FON1 led to a slight reduction of the SAM size in wild type, suggesting that TAB1 is not a positive regulator of stem cells

- CUR1, SaM, CURLED LATER1 encoding the largest subunit of the Elongator complex has a unique role in leaf development and meristem function in rice , The shoot apical meristem (SAM) was small and the leaf initiation rate was low, suggesting that the activity of the SAM seemed to be partially reduced in cur1
