Transcription profiling of rice reveals plant mutagenesis may induce more transcriptomic changes than transgene insertion

ABSTRACT: Controversy regarding genetically modified (GM) plants and their potential impact on human health contrasts with the tacit acceptance; of other plants that were also modified, but not considered as GM products (e.g., varieties raised through conventional breeding such as mutagenesis). What is beyond the phenotype of these improved plants? Should mutagenized plants be treated differently from transgenics? We have evaluated the extent of transcriptome modification occurring during rice improvement through transgenesis versus mutation breeding. We used oligonucleotide microarrays to analyze gene expression in four different pools of four types of rice plants and respective controls: (i) a; gamma-irradiated stable mutant, (ii) the M1 generation of a 100-Gy gamma-irradiated plant, (iii) a stabl
