| Title |
h1_3_f3.rna |
| Sample type |
SRA |
| |
|
| Source name |
rosette leaf
|
| Organism |
Arabidopsis thaliana |
| Characteristics |
ecotype: Col-0
tissue: rosette leaf
|
| Growth protocol |
Arabidopsis were sown to soil, stratified for 4 days at 4degC and transferred to controlled environment chambers where they were grown in 16h light / 8hr dark at 20deg C.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Rosette leaves from the F3 generation were flash frozen in liquid nitrogen, pulverized with mortar and pestle on dry ice, and the resulting material was subjected to vortexing in Trizol (Invitrogen, cat. no. 15596-026). Chloroform was then added at one-fifth the total volume and further vortexing was carried out until the solution appeared homogenous. RNA was subsequently pelleted in ice-cold isopropanol. The resuspended RNA was subjected to rRNA removal with Ribo-zero plant kit (Illumina, MRZPL1224) according to the manufacturer’s protocol.
50ng ribo-depleted was used for library preparation with the Scriptseq kit (Epicentre, cat. no. SSV21124) following the manufacturer’s protocol but with the following modifications: the RNA fragmentation step was extended to 10 minutes, and the temperature was increased to 90°C.

| Data processing |
Bisulfite libraries were mapped to the genome following adaptor trimming with trim_galore (https://github.com/FelixKrueger/TrimGalore/blob/master/Docs/Trim_Galore_User_Guide.md) using BSMAP (Xi and Li 2009) using default settings for all analyses, except single-read analyses, for which we used Bismark (Kruger and Andrews 2011).
BSMAP output was converted to per-base methylation scores with BSMAP's methratio.py script using the -r setting to remove PCR duplicates.
Methratio.py output was converted to GFF and further processed and analysed using commands and workflows outlined in https://github.com/dblyons/modeling_h1ddm1/
Genome_build: TAIR10
Supplementary_files_format_and_content: tab-seperated methratio.py output: chromosome, position, strand, cytosine context, ratio eff_CT_count, C_count, CT_count, rev_G_count, rev_GA_count, CI_lower, CI_upper.
