Gene Symbol
- Os06g0607700 <=> OsABCG15,ABCG15
Function
- OsABCG15 may play a key function in the processes related to sporopollenin biosynthesis or sporopollenin transfer from tapetal cells to anther locules.
- OsABCG15 plays a critical role in exine formation and pollen development, similar to the homologous gene of AtABCG26 in Arabidopsis.
Function
- The researchers generated a rice mutant library of a rice cultivar 02428 (O. sativa ssp. japonica) by 60 Co g‐ray irradiation (Y‐G Liu,unpubl. data, 2008). One of the mutants produced more tillers (Figure 1A), and exhibited collapsed anthers with smaller size and white color, and no pollen grains, thus leading to complete spikelet sterility (Figure 1B–D).
- Genetic analysis indicated that the male sterility of this mutant is sporophytic and is controlled by a single recessive locus, namely OsABCG15 .
Expression
- Expression analysis showed that OsABCG15 is expressed specifically in developmental anthers from stage 8 (meiosis II stage) to stage 10 (late microspore stage).
