Information
- Symbol: OsPAO5
- MSU: LOC_Os04g57560
- RAPdb: Os04g0671300
Publication
- Targeted Mutagenesis of POLYAMINE OXIDASE 5 that Negatively Regulates Mesocotyl Elongation Enables the Generation of Direct-seeding Rice with Improved Grain Yield, 2020, Mol Plant.
Genbank accession number
Key message
- Here, we established that OsPAO5 expression in rice seedlings is increased in the presence of light, and inhibited by darkness
- Intriguingly, knocking out of OsPAO5 can remarkably increase the grain weight, grain numbers and yield potential
- Nucleotide polymorphism analysis revealed that an SNP variation (PAO5-578G/A) in the 578 bp upstream of OsPAO5 start codon alters its expression, which is further selected during rice mesocotyl domestication
