| Title |
wt Col mock-IP sRNA replicate A |
| Sample type |
SRA |
| |
|
| Source name |
inflorescence (stage 1-12) immature flower buds
|
| Organism |
Arabidopsis thaliana |
| Characteristics |
antibody: mock
genotype/variation: wt Col
tissue: inflorescence (stage 1-12) immature flower buds
ecotype: Columbia
|
| Growth protocol |
Plants were grown under 16-hour day conditions at 22ºC in a growth chamber. All tissue is inflorescence (stage 1-12) immature flower buds.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Inflorescence small RNA was isolated with TRIzol reagent (Invitrogen) and concentrated using the mirVana microRNA Isolation Kit (Ambion).
For AGO1-IP samples, AGO1 was immunoprecipitated from inflorescence tissue using Agrisera anti-AGO1 primary antibody. RNA was isolated from AGO1-IP or mock-IP samples using TRIzol reagent.
Size-enriched small RNAs were prepared using the TruSeq Small RNA Library Preparation Kit (Illumina).
Multiplexed libraries were sequenced on HiSeq2500 or HiSeq4000.

| Description |
IP small RNA
|
| Data processing |
Small RNA sequencing reads were processed as in McCue et al., PMID: 25388951 to remove adapters, tRNAs, rRNAs and filtered for size 18-28 nt.
ShortStack (Johnson et al., PMID: 27175019) was used to map the reads to the Arabidopsis genome (TAIR10) with fractional seeded guide used for multi-mapping reads.
Genome_build: TAIR10
Supplementary_files_format_and_content: Reads per million sequenced (RPM) is provided for each filtered small-RNA read.
