Gene Details:

• MSU gene ID: LOC_Os08g35110
• RAPdb gene ID: Os08g0452500
• Gene Symbol: OsSAUR33
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The Rice Small Auxin-Up RNA Gene OsSAUR33 Regulates Seed Vigor via Sugar Pathway during Early Seed Germination.
• Here, we observed that disruption of OsSAUR33 resulted in reduced germination rates and low seed uniformity in early germination.
• RNA-seq analysis revealed that OsSAUR33 modulated seed vigor by affecting the mobilization of stored reserves during germination.
• Disruption of OsSAUR33 increased sugar-sensitive phenotypes in early germination, suggesting OsSAUR33 likely affects seed vigor through the sugar pathway.
• One elite haplotype of OsSAUR33 associated with higher seed vigor was identified mainly in indica accessions.
• This study provides insight into the effects of OsSAUR33 on seed vigor in rice.
• OsSAUR33 interacted with the sucrose non-fermenting-1-related protein kinase OsSnRK1A, a regulator of the sugar signaling pathway, which influences the expression of sugar signaling-related genes during germination.
• Disruption of OsSAUR33 increased the soluble sugar content in dry mature grains and seeds during early germination.
