| Sample type |
SRA |

|
| Source name |
4-leaf seedling
|
| Organism |
Oryza sativa Japonica Group |
| Characteristics |
treatment: Drought
|
| Treatment protocol |
Drought treatment was carried out by stopping water supply for 7 days until the relative soild water content was below 10%. Heat treatment was performed by placing the seedlings in a growth chamber with the air temperature of 45˚C and relative humidity of 70% for 6 hours.
|
| Growth protocol |
The onac023 mutant and DJ seeds were sprouted on half-strength MS medium in the dark for 2-3 days at 28°C, and then 4-5 days in the greenhouse. The seedlings were then moved to pots with sand/paddy (1:3) soil under natural conditions at Wuhan, China.

| Extracted molecule |
total RNA |
| Extraction protocol |
The total RNAs were extracted from the seedlings using TRIzol reagent (Invitrogen™) according to the manufacturer’s instructions. The ChIP assay was performed according to Chris Bowler (Bowler et al., 2004) with some modifications. Briefly, 3 g seedling tissue were cross-linked in 1% formaldehyde by vacuum for 30 minutes. The chromatin was extracted on ice as described by Bowler method and sheared to 200-500 bp fragments by sonication. Subsequently, the DNA fragments were immunoprecipitated by homemade anti-ONAC023 polyclonal antibody. The ChIP DNA was eluted, purified, and dissolved in ddH2O.
RNA-seq and ChIP-seq libraries were prepared for sequencing using standard Illumina protocols

| Description |
mutCK_D_2
|
| Data processing |
Sequencing reads were mapped to rice reference genome (MSU7) using Hisat2 (for RNA-seq) and Bowtie2 (for ChIP-seq)
RNA-seq transcripts were assembled and count by StringTie and the differential expression was determined by R package DESeq2
ChIP-seq peaks and the signal tracks were generated by MACS2.
Genome_build: MSU7
Supplementary_files_format_and_content: The tab-delimited text file (count.txt) includes read counts for each RNA-seq sample. The bigWig files (.bw) record ChIP-Seq tag densities.
