Abstract excerpt
Grain filling is a complex agronomic trait that directly determines grain weight and quality in rice (Oryza sativa). Nevertheless, key factors affecting grain filling remain poorly understood. Here, we identified a grain filling gene, OsPK3, encoding a pyruvate kinase (PK). The loss of function of OsPK3 caused reduced PK activity and Suc translocation defects from source to sink in rice, which led to compromised...
