The Rho-family GTPase OsRac1 controls rice grain size and yield by regulating cell division [Plant Biology]

Grain size is a key factor for determining grain yield in crops and is a target trait for both domestication and breeding, yet the mechanisms underlying the regulation of grain size are largely unclear. Here we show that the grain size and yield of rice (Oryza sativa) is positively regulated...
