| Title |
H3K4me3_WST7 |
| Sample type |
SRA |
| |
|
| Source name |
immature wrapped leaf
|
| Organism |
Zea mays |
| Characteristics |
cultivar: B73
tissue: immature wrapped leaf
growth condition: drought stress + recovery 7days
antibody: H3K4me3 (Active Motif, Cat. 39159)
|
| Treatment protocol |
Stresses were applied for 10 days: control plants (NS) were watered with 75% of disposable water at 0.1dS/m salt concentration; drought-stressed plants (WS) with 25% of disposable water at 0.1dS/m salt concentration.
|
| Growth protocol |
Maize plants were grown in greenhouse until V5-V6 leaf stage with normal watering
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Chromatin was purified from frozen tisses, sonicated and immuno-precipitated with antibody.

| Description |
processed data file:
H3K4me3_rawcounts.txt
|
| Data processing |
base-calling and demultiplexing with Illumina CASAVA 1.8
manual trimming of 5 bp at the 3’ end
mapping with bowtie2, allowing at most 3 substitutions per read and no indels
Genes significantly enriched for a ChIP-Seq with respect to the WC control or between two conditions were identified by multiple 2 x 2 χ2 tests
Genome_build: RefGen ZmB73 Assembly AGPv4 + Zea_mays.AGPv4.34.gtf Gramene annotation
Supplementary_files_format_and_content: tab-delimited matrix with raw read counts for each gene in each sample/antibody. For H3K27me3 the gene boundaries are from TSS to TTS. For H3K4me3 and H3K9ac gene boundaries are from 0bp to +1000bp with respect to the TSS.
