Transcription of RTN20. Reverse transcriptase PCR was performed in wild type (WT) Col0 plants as well as rtn20 and rtn6 mutant plants. It was also distinguished between root and cotyledon (cot) tissue. RTN20-mRNA was detectable in WT roots but not in cotyledon tissue or in the rtn20 mutant. RTN6 could be detected in the rtn20 mutant but not in the rtn6 mutant.
