Gene Details:

• MSU gene ID: LOC_Os11g05470
• RAPdb gene ID: Os11g0152500
• Gene Symbol: OsCEN2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsCEN2 influenced grain size by restricting cell expansion in the spikelet hull and seed filling.
• Here, we report that the rice CENTRORADIALIS (CEN) family member OsCEN2 (also known as Rice TFL1/CEN homolog, RCN1), a phosphatidylethanolamine-binding protein (PEBP) family protein, negatively controls grain size in rice.
• In in vivo and in vitro experiments, OsCEN2 physically interacted with a G-box factor 14-3-3 homolog, GF14f, which negatively regulates grain size.
• Here, we reported that the rice OsCEN2 gene can negatively regulate seed germination.
• The results of qRT-PCR showed that the OsCEN2 expression was increased in the early stage of seed germination.
• This study reveals that OsCEN2 regulates the germination speed by affecting the content of ABA during seed germination and provides a theoretical basis for research on rice direct seeding.
