Gene expression profiling in leaf and panicles of non-transgenic and HMB4 over-expression line.

The profiling was conducted with the Rice 3'-Tiling 135k Microarray designed from 31,439 genes deposited at IRGSP, RAP2 database (http://rapdb.lab.nig.ac.jp). In this research, an array of 31,439 rice genes was used to elucidate gene expression in leaf and panicles of non-transgenic and HMB4 over-expression line. The analyses show that transgenic rice induces early flowering due to an enhancement of stress response. A total of 20 chips were used for microarray. Total RNAs were extracted from rice leaf and panicle. Experiments were duplicated.
