Check if the same lab product or an alternative is used in the 5 most similar protocols
Cultivated individuals of Ae. indica were obtained from a gardening shop (http://www.nihonkaki.com/; Last accessed November 6, 2018), whereas plant samples of the other four parasite species were collected from the wild. See supplementary table S1, Supplementary Material online for the sampling locations.
Total RNA was extracted from several tissues (tissues from a few individuals were pooled) for each species (supplementary table S1, Supplementary Material online) by using RNeasy Plant Mini kit (Qiagen) following the manufacturer’s instructions. Genomic DNA was extracted from stem or leaves (a single individual per species) using DNeasy Plant Mini kit (Qiagen) following the manufacturer’s instructions.
For RNA sequencing, tissue-specific libraries were constructed for each species, and the libraries were sequenced separately by using the Illumina HiSeq2000 sequencing platform. Short reads of mRNAs (paired-end reads of 90 bp with an insert of 200 bp) were obtained from 1 to 3 libraries for each species (supplementary table S1, Supplementary Material online). We also sequenced genomic DNA of the five parasite species using the Illumina HiSeq2000 sequencing platform (paired-end reads of 90 bp with an insert size of 500 bp; supplementary table S2, Supplementary Material online).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Poly(A) mRNA from the total RNA was purified using oligo(dT) beads. Following purification, mRNA was fragmented into small pieces using divalent cations. The first cDNA strand was synthesized using random hexamer primers for reverse transcription with cleaved mRNA fragments serving as templates. The second strand cDNA was synthesized using DNA polymerase I (Qiagen), incubated with RNase H (Invitrogen), dNTPs and buffer. Following end repair, a single “A” was added to the blunt end, and then adaptors were added to the purified double stranded cDNA fragments. The products (150–300 bp) are purified and enriched with PCR (15 cycles) to create the final cDNA library. The PCR amplification products for transcriptome sequencing were sequenced with Illumina HiSeq™ 2000 sequencing platform, using paired-end reads with a length of 2 × 100 nucleotides, and this was carried out at Beijing BerryGenomics Co. Ltd. (Beijing, China). The PCR amplification products for gene expression profiling were sequenced with Illumina HiSeq™ 2000 at Genergy BioTechnology Co. Ltd. (Shanghai, China).

Total RNA was isolated using RNApure® total RNA rapid extraction kit according to the manufacturer’s instruction (Aidlab Biotechnologies, Beijing). The yield and purity of RNA were evaluated by measurement of absorbance at 260 and 280 nm. RNA integrity was confirmed using Agilent 2100 Bioanalyzer (Agilent Technologies) with a minimum RNA integrated number (RIN) value of 7.0. Total RNA isolated from the samples of three biological replicates at each time point (24 and 48 hpi) was combined for RNA-Seq. Poly(A) + mRNA was enriched from total RNA using oligo(dT) magnetic beads and used for library construction. RNA-Seq libraries were constructed following the standard pipeline at Beijing Genomics Institute (BGI) in Shenzhen, China. Reads of 49 bp length were generated with the Illumina HiSeq™ 2000 sequencing platform at BGI.

The male P. simonii seeds provided by Luoning Bureau of Forest, Henan Province, China and planted at the Xiashu Forest Farm of Nanjing Forestry University, Jurong, Jiangsu Province, China. Fresh leaves were collected and immediately frozen in liquid nitrogen, followed by preserving the leaves at –80°C in the laboratory prior to DNA extraction. The total genomic DNA was extracted from leaves using the CTAB protocol (Arseneau et al., 2017 (link)), and a library with an insert size of 20 kb was constructed using a BluePippin DNA size selection instrument (Sage Science, Beverly, MA, United States) with a lower size limit of 10 kb. The prepared library was sequenced on the PacBio Sequel platform (Pacific Biosciences, United States) at Frasergen Technologies Corporation, Wuhan, China. After the removal of adapter sequences using SMRTlink (v7.0.12), the remaining sequences were used for genome assembly and error correction. Additionally, to collect the contigs assembled by the PacBio sequencing data, we also sequenced the same genomic DNA afore-described on the Illumina HiSeq 2000 sequencing platform at Biomarker Technologies Corporation, Beijing, China.

Transcriptome Profiling via RNA-Seq

Check if the same lab product or an alternative is used in the 5 most similar protocols
A minimum of 3 µg of total RNA was oligo (dT)‐selected using the Dynabeads mRNA purification kit (Invitrogen, Carlsbad, CA). mRNA extracted from the total RNA was fragmented into short fragments with a fragmentation buffer (Ambion, Austin, TX), and these short fragments were used as templates to synthesize double‐stranded cDNA. The cDNA library was constructed and sequenced on an Illumina HiSeq 2000 sequencing platform (Berry Genomics, Beijing, China). The gene expression levels for each transcript were assessed as the number of reads per kilobase of exon model per million mapped reads (RPKM) using only uniquely mapped reads in the exonic regions. A gene was considered significantly and differentially expressed if its expression differed between any two samples with a fold change >2 and a p‐value < 0.05, as calculated by Cufflinks. RNA‐Seq data are available in the Gene Expression Omnibus database (www.ncbi.nlm.nih.gov/geo/, accession numbers GSE166203 and GSE189947).

To cover more tissue-specific transcripts in E. sibiricus, every sample was adjusted to the same concentration (400 ng/μl), and a total of 20 μg of RNA was pooled equally from the 11 tissues for preparation of the cDNA library. The cDNA library construction was conducted via the mRNA-Seq Sample Preparation Kit (Illumina Inc.) according to the manufacturer’s instructions. Briefly, the poly (A) mRNA was isolated by magnetic oligo (dT) beads, and first-strand cDNA was detected using random hexamer primers and reverse transcriptase (Invitrogen). The short cDNA fragments were then purified using a MinElute PCR Purification Kit (Qiagen) and resolved with EB buffer (Qiagen) for end reparation and adding poly (A). Finally, sequencing adapters were ligated to the fragments. The libraries were sequenced using the Illumina HiSeq2000 sequencing platform at the BGI TECH Company (Shenzhen, China). In addition, the processing of the fluorescent images for sequence base-calling and calculation of quality values was performed using the Illumina data processing pipeline, which yielded 100 bp paired-end reads.

The sequencing library was constructed using the NEBNext Ultra™ RNA Library Prep Kit for Illumina (NEB, Ipswich, MA, USA). Oligo(dT) magnetic beads were used to enrich for mRNAs with a poly-A tail from the total RNA. The RNA was fragmented into pieces approximately 300 bp in length using ion disruption. The first strand of cDNA was synthesized from RNA using 6-base random primers and reverse transcriptase. The second strand of cDNA was synthesized using the first-strand cDNA as the template. After library construction, PCR amplification was used to enrich library fragments. The library size was selected to be 380 bp based on fragment size, and the library quality was checked using an Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA). The constructed library was sequenced by Personal Biotechnology Co., Ltd (Shanghai, China) using the Illumina HiSeq 2000 sequencing platform (Illumina, San Diego, CA, USA) for paired-end (PE) sequencing. The quality of obtained raw reads was checked with the FastQC tool. To acquire valid sequencing data, the raw data were filtered using Cutadapt software (v2.3). In this step, the reads with adapters or ambiguous bases (‘N’ > 5% of a read), and low-quality reads (with more than 10% Q < 20) bases were discarded.

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.
