| Research Abstract |
‘Rice with low epiphytic bacteria (RLE)’, which includes culturable and unculturable bacteria, was developed by sterilizing rice seed. The population of total epiphytic bacteria in RLE is significantly lower more than 1/1000 of that in wild rice. RLE is suggested to be useful for excluding genes’ expression by resident bacteria on plants, which we call it as ‘noise’ cuased by epiphytic bacterial, from genes’ expression of rice plant itself. Transcriptome analyses of RLE and wild rice were conducted. The results showed the increase in genes’ expression associated with DNA replication, DNA repair, protein synthesis and transport in RLE as compared to in wild rice. The results suggest that‘noises’ caused by bacteria inhabiting rice plant are included within the expressions of genes obtained by a microarray analysis of rice plants.
