The rice Os03g0597200 was reported as YSA in 2012  by researchers from China.
- Os03g0597200 <=> YSA,OsYSA,
- Map-based cloning revealed that YSA encodes a PPR protein with 16 tandem PPR motifs.
- The researchers demonstrated that YSA can be used as an early marker for efficient identification and elimination of false hybrids in commercial hybrid rice production, resulting in yield increases by up to approximately 537 kg ha 21 .
- YSA is highly expressed in young leaves and stems, and its expression level is regulated by light.
- The researchers showed that the YSA mutation has no apparent negative effects on several important agronomic traits, such as fertility, stigma extrusion rate, selfed seed-setting rate, hybrid seed-setting rate, and yield heterosis under normal growth conditions.
