- Genome-wide analysis of cyclin family in rice Oryza Sativa L., 2006, Mol Genet Genomics.
- Functional conservation of the meiotic genes SDS and RCK in male meiosis in the monocot rice, 2009, Cell Res.
- OsSDS is essential for DSB formation in rice meiosis., 2015, Front Plant Sci.
- Genbank accession number
- Key message
- Quantitative real-time RT-PCR analysis indicated that rice SDS and RCK are expressed preferentially in young flowers, and transgenic RNAi rice lines with reduced expression of these genes exhibited normal vegetative development, but showed significantly reduced fertility with partially sterile flowers and defective pollens
- Because rice and Arabidopsis, respectively, are members of monocots and eudicots, two largest groups of flowering plants, our results suggest that the functions of SDS and RCK are likely conserved in flowering plants
- The Arabidopsis SDS (SOLO DANCERS) and RCK (ROCK-N-ROLLERS) genes are important for male meiosis, but it is still unknown whether they represent conserved functions in plants
- Functional conservation of the meiotic genes SDS and RCK in male meiosis in the monocot rice
- SDS deficiency also caused a decrease in pollen amounts
- Further cytological examination of male meiocytes revealed that the SDS deficiency led to defects in homolog interaction and bivalent formation in meiotic prophase I, and RCK deficiency resulted in defective meiotic crossover formation
- The Ossds mutant is normal in vegetative growth but both male and female gametes are inviable
- No γH2AX immunosignals in Ossds meiocytes together with the suppression of chromosome fragmentation in Ossds-1 Osrad51c, both provide strong evidences that OsSDS is essential for meiotic DSB formation
- Immunostaining investigations revealed that meiotic chromosome axes are normally formed but both SC installation and localization of recombination elements are failed in Ossds

- OsPHL3, SDS~OsSDS, Identification of a G2-like transcription factor, OsPHL3, functions as a negative regulator of flowering in rice by co-expression and reverse genetic analysis., Further analysis indicated that OsPHL3 delayed flowering time by down-regulating the expression of Hd3a and RFT1 through promoting Hd1 under long-day conditions (LDs), or suppressing Ehd1/Hd1 under short-day conditions (SDs)
- Hd1, SDS~OsSDS, Hd1, Ghd7, and DTH8 synergistically determine the rice heading date and yield-related agronomic traits., Under SDs, Hd1 competes with various heading suppressors to promote heading
- OsFTIP9, SDS~OsSDS, The tetratricopeptide repeat protein OsTPR075 promotes heading by regulating florigen transport in rice., Here, we report that FT-INTERACTING PROTEIN9 (OsFTIP9) specifically regulates rice flowering time under SDs by facilitating Hd3a transport from companion cells to sieve elements
