- Genbank accession number
- Key message
- Immunological assays indicated that OsC6 is widely distributed in anther tissues such as the tapetal cytoplasm, the extracellular space between the tapetum and middle layer, and the anther locule and anther cuticle
- Here, we report the crucial role of OsC6 in regulating postmeiotic anther development in rice (Oryza sativa)
- OsC6 expression is mainly detectable in tapetal cells and weakly in microspores from stage 9 to stage 11 of anther development
- These data suggest that OsC6 plays a crucial role in the development of lipidic orbicules and pollen exine during anther development in rice
- OsC6, encoding a lipid transfer protein, is required for postmeiotic anther development in rice
- The expression levels of Osc6, OsRAFTIN and TDR, which are tapetum-specific genes, were unaffected by high temperatures
- Extra granule-like structures were observed on the inner surface of the tdr tapetal layer when the expression of OsC6 was driven by the TDR promoter compared with the tdr mutant
- Furthermore, additional evidence is provided that the expression of OsC6 is positively regulated by a basic helix-loop-helix transcription factor, Tapetum Degeneration Retardation (TDR)
- Connection
- OsC6, TDR, High temperatures cause male sterility in rice plants with transcriptional alterations during pollen development, The expression levels of Osc6, OsRAFTIN and TDR, which are tapetum-specific genes, were unaffected by high temperatures
- LTP2~nsLTP2, OsC6, OsC6, encoding a lipid transfer protein, is required for postmeiotic anther development in rice, Found in monocots, OsC6 belongs to a distinct clade from previously identified LTP1 and LTP2 family members found in both dicots and monocots
- OsC6, TDR, OsC6, encoding a lipid transfer protein, is required for postmeiotic anther development in rice, Furthermore, additional evidence is provided that the expression of OsC6 is positively regulated by a basic helix-loop-helix transcription factor, Tapetum Degeneration Retardation (TDR)

- OsC6, OsCP1, The rice tapetum degeneration retardation gene is required for tapetum degradation and anther development, More importantly, two genes, Os CP1 and Os c6, encoding a Cys protease and a protease inhibitor, respectively, were shown to be the likely direct targets of TDR through chromatin immunoprecipitation analyses and the electrophoretic mobility shift assay

- OsABCG26, OsC6, An ABC transporter, OsABCG26, is required for anther cuticle and pollen exine formation and pollen-pistil interactions in rice, Expression of some key genes involved in lipid metabolism and transport, such as UDT1, WDA1, CYP704B2, OsABCG15, OsC4 and OsC6, was significantly altered in osabcg26 anther, possibly due to a disturbance in the homeostasis of anther lipid metabolism and transport
- OsC6, PTC1~OsMS1, OsMS1 functions as a transcriptional activator to regulate programmed tapetum development and pollen exine formation in rice., Results of qPCR suggested that the expression of the genes associated with tapetal PCD and pollen wall biosynthesis, such as EAT1, AP37, AP25, OsC6 and OsC4, were significantly reduced in osms1 mutant
- OsC6, OsLTP47, OsLTP47 may function in a lipid transfer relay essential for pollen wall development in rice., Yeast two-hybrid and pull-down assays reveal that OsLTP47 physically interacts with another LTP, OsC6
- OsC6, OsLTP47, OsLTP47 may function in a lipid transfer relay essential for pollen wall development in rice., These findings suggest that the plasma membrane-localized OsLTP47 may function as a mediator in a lipid transfer relay through association with cytosolic and/or locular OsC6 for pollen wall development and that various LTPs may function in a coordinated manner to transport lipid molecules during pollen wall development
