a mutant allele of HDA6, shi5, was identified through EMS mutagenesis and map-based cloning. The mutant shi5 shows some phenotypes not reported previously. Using total RNA samples extracted from 10d-old seedlings growing on 1/2MS agar plates were used for the RNA sequencing. The wild type is a transgenic line containing PSOT12-LUC contruct in the Col background. This line is used as the materials for mutagenesis to produce and screen shi5.
