Sample GSM3762839 Query DataSets for GSM3762839
Status Public on Nov 01, 2019
Title 5Pi_tZ_R1
Sample type SRA
Source name roots
Organism Arabidopsis thaliana
Characteristics ecotype: Columbia
treatment: grown without phosphate and treated with trans-zeatin
Growth protocol Arabidopsis thalinaan (Col-0) seedlings were grown in Murashige and Skoog medium containing 625 or 5 µM of phosphate for 8 days and then treated with 5 µM of cis-zeatin or trans-zeatin fro 8 hours.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from Arabidopsis plants using the Trizol reagent and RNeasy columns (Qiagen). Quantity and quality measurements were taken using a NanoDrop spectrophotometer and Bioanalyzer.
After the total RNA extraction and DNase I treatment, magnetic beads with Oligo (dT) are used to isolate mRNA. Mixed with the fragmentation buffer, the mRNA is fragmented into short fragments. Then cDNA is synthesized using the mRNA fragments as templates. Short fragments are purified and resolved with EB buffer for end reparation and single nucleotide A (adenine) addition. After that, the short fragments are connected with adapters. After agarose gel electrophoresis, the suitable fragments are selected for the PCR amplification as templates. During the QC steps, Agilent 2100 Bioanaylzer and ABI StepOnePlus Real-Time PCR System are used in quantification and qualification of the sample library. At last, the library could be sequenced using Illumina HiSeqTM 2000 or other sequencer when necessary
