- Genbank accession number
- Key message
- Based on map-based cloning and sequence analysis, we identified a 1,459-bp deletion in an adenosine triphosphate (ATP)-binding cassette (ABC) transporter gene, OsABCG15, causing abnormal anthers and male sterility
- Consistently, histological analysis showed that osabcg15 mutants developed obvious abnormality in postmeiotic tapetum degeneration, leading to rapid degredation of young microspores
- Expression analysis showed that OsABCG15 is expressed specifically in developmental anthers from stage 8 (meiosis II stage) to stage 10 (late microspore stage)
- Two genes CYP704B2 and WDA1, involved in the biosynthesis of very-long-chain fatty acids for the establishment of the anther cuticle and pollen exine, were downregulated in osabcg15 mutant, suggesting that OsABCG15 may play a key function in the processes related to sporopollenin biosynthesis or sporopollenin transfer from tapetal cells to anther locules
- The ATP-binding cassette transporter OsABCG15 is required for anther development and pollen fertility in rice
- The results suggest that OsABCG15 plays a critical role in exine formation and pollen development, similar to the homologous gene of AtABCG26 in Arabidopsis
- OsABCG15 encodes a membrane protein that plays an important role in anther cuticle and pollen exine formation in rice.
- An ABC transporter gene ( OsABCG15 ) was proven to be involved in pollen development in rice
- This osabcg15 mutant failed to produce any viable pollen and was completely male sterile
- Histological analysis indicated that osabcg15 exhibited an undeveloped anther cuticle, enlarged middle layer, abnormal Ubisch body development, tapetum degeneration with a falling apart style, and collapsed pollen grains without detectable exine
- Our results suggested that OsABCG15 played an essential role in the formation of the rice anther cuticle and pollen exine
- OsABCG15 encodes a membrane protein that plays an important role in anther cuticle and pollen exine formation in rice

- OsABCG15, OsABCG26, Two ATP Binding Cassette G ABCG Transporters, OsABCG26 and OsABCG15, Collaboratively Regulate Rice Male Reproduction., Here, we report the significant role of OsABCG26 in regulating the development of anther cuticle and pollen exine together with OsABCG15 in rice
- OsABCG15, OsABCG26, Two ATP Binding Cassette G ABCG Transporters, OsABCG26 and OsABCG15, Collaboratively Regulate Rice Male Reproduction., osabcg26 osabcg15 double mutant displays an almost complete absence of anther cuticle and pollen exine, similar to that of osabcg15 single mutant
- OsABCG15, OsABCG26, Two ATP Binding Cassette G ABCG Transporters, OsABCG26 and OsABCG15, Collaboratively Regulate Rice Male Reproduction., Taken together, we propose that OsABCG26 and OsABCG15 collaboratively regulate rice male reproduction: OsABCG26 is mainly responsible for the transport of lipidic molecules from tapetal cells to anther wall layers, while OsABCG15 mainly is responsible for the export of lipidic molecules from the tapetal cells to anther locules for pollen exine development
- OsABCG15, OsABCG26, 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
- CYP703A3, OsABCG15, Identification of cyp703a3-3 and analysis of regulatory role of CYP703A3 in rice anther cuticle and pollen exine development., Results of qPCR suggested CYP703A3 mainly expressed in anthers with greatest abundance at microspore stage, and genes involved in sporopollenin precursors formation and transportation, such as GAMYB, TDR, CYP704B2, DPW2, OsABCG26 and OsABCG15, were significantly reduced in cyp703a3-3
