- The ATP-binding cassette transporter OsABCG15 is required for anther development and pollen fertility in rice, 2013, J Integr Plant Biol.

- Genbank accession number
- Key message
- 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
- We report here the isolation and characterization of a rice (Oryza sativa) male sterile mutant, cyp704B2, which exhibits a swollen sporophytic tapetal layer, aborted pollen grains without detectable exine, and undeveloped anther cuticle
- In addition, chemical composition analysis indicated that cutin monomers were hardly detectable in the cyp704B2 anthers
- The CYP704B2 transcript is specifically detected in the tapetum and the microspore from stage 8 of anther development to stage 10

- CYP704B2, 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
