For transcriptome analysis, thirty days old seedlings (root and shoot) were used for RNA isolation and sequencing on the Illumina HiSeq4000 platform (Genotypic Technology Pvt. Ltd., Bangalore). RNA extractions were performed independently from each of the three biological replicates. Total RNA was extracted from root and shoot of all the three treatment conditions, i.e.
C, T1 and T2, using the Qiagen RNeasy Plant Mini kit (Netherland) as per the manufacturer's instruction. The yield and purity of RNA were evaluated by Nanodrop1000 spectrophotometer (NanoDrop, USA) and 1% denaturing RNA agarose gel, respectively. Before library preparation, the quality of all the RNA samples was thoroughly evaluated by Bioanalyzer 2100 (Agilent, USA) to ensure >8.5 RNA integrity number (RIN). RNA-seq library was prepared using NEBNext® Ultra™ directional RNA library prep kit (New England BioLabs, MA, USA) following the manufacturer's instruction. The sequencing libraries were quantified by Qubit fluorometer (Thermo, USA) followed by an analysis of fragment size distribution on Agilent 2200 Tapestation (Agilent, USA). The average mean of the fragment size of all the libraries was 465 bp. The 2×150 bp chemistry was used for sequencing on the Illumina HiSeq4000 platform to produce on an average of 45.7 million raw sequencing reads per library.

Optimized RNA-Seq Workflow for Aged Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
We applied an optimized RNA-Seq workflow, which we had tested on body fluid samples and described in our previous publication [38] . Total RNA libraries were constructed using the Trio RNA-Seq kit (Nugen, Leek, The Netherlands) according to the manufacture's protocol, without ribosomal RNA depletion. The kit is optimized for low input and challenging samples and is suitable to generate sequencing libraries from total RNA using universal priming [39] and is layed-out for 500 pg to 50 ng total RNA. If 50 ng in 10 µl could not be reached, the maximal volume of RNA extract (10 µl) was used. Most samples (97%) reached the recommended input amounts. Libraries were checked for quality with the TapeStation 4200 system for nucleic acid analysis (Agilent Technologies, Santa Clara, USA). Libraries generated from fresh (day 0), 1 day, 7 days and 4 weeks old stains were sequenced on the Illumina HiSeq4000 platform, generating 1 × 125 bp reads using a single indexing (8 bp) strategy. Since the Illumina HiSeq4000 platform at our sequencing facility (Functional Genomics Center Zurich, FGCZ) was replaced during the course of this project, the 6 months, 1 and 1.5 year old samples were sequenced on an Illumina NovaSeq6000 platform, generating 1 × 100 bp reads using a unique dual indexing strategy.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
