DEG of panicle primordia in ZH11 and OsGATA6-AM lines at the In2 and In3 stages

To investigate how OsGATA6 regulates heading date, grain number per panicle, and grain phenotypes, we collected panicle primordia of ZH11 and OsGATA6-AM lines at the In2 and In3 stages. We analyzed gene expression using a rice expression profiling chip. Compared with ZH11, OsGATA6-AM lines had 818 up-regulated genes and 284 down-regulated genes According to SEM observations of panicle primordia, we selected panicle primordia at the In2–In3 stages from wild-type ZH11 and OsGATA6-AM lines and analyzed differentially expressed genes using a rice expression profile chip (Agilent Technologies, Santa Clara, CA, USA).Each sample had three biological replicates.
