We used the samples harvested after one and three days for transcriptome sequencing. The TRIzol method was used for total RNA extraction. The frozen muscle tissue was immersed with TRIzol™ Reagent (Thermo-Fisher Scientific, Waltham, MA, USA) and was crushed using a tissue crusher until there were no visible solids to ensure that the muscle tissue was completely dissolved. The RNA was extracted with chloroform and isopropanol in sequence, eluted with 75% ethanol, and finally dissolved in diethylpyrocarbonate water. We used 2 μg total RNA to enrich mature mRNA using magnetic beads carrying Oligo (dT), and the enriched RNA was interrupted after purification. Random primer fragments were used as a template to synthesize the first-strand cDNA, which was then used as a template to synthesize double-stranded DNA. A series of treatments such as end repair, A-tailing, and connection of sequencing adapters were performed, and the samples were amplified using polymerase chain reaction to complete library construction. Quality testing was conducted using the Agilent 2100 Bioanalyzer (Agilent Technologies, Inc., Santa Clara, CA, USA). The Illumina HiSeq X Ten sequencer (Illumina Inc., San Diego, CA, USA) was used for sequencing, and 150 bp paired-end data was obtained. The gene expression dataset is available on ArrayExpress and the accession number is E-MTAB-10794.

After sequencing, raw data were saved in FASTQ format. Illumina sequencing adapters and low quality reads (< 80 bp) were filtered by Cutadapt [14 ]. Clean reads were aligned to UCSC hg19 human reference genome using the Burrows-Wheeler Alignment [15 (link)] tool. Duplicated reads were removed using Picard (http://broadinstitute.github.io/picard). Insertions, deletions and SNP variants were detected and filtered using the Genome Analysis Toolkit [16 (link)]. Then the identified variants were annotated using ANNOVAR [17 (link)] and associated with the following databases: 1000 genomes, Exome Aggregation Consortium, The Human Gene Mutation Database, and predicted by Mutation Taster (MT) [18 (link)], Sorting Intolerant From Tolerant (SIFT) [19 (link)], PolyPhen-2 (PP2) [20 (link)] and Genomic Evolutionary Rate Profiling (GERP++) [21 (link), 22 (link)]. Splice-site were predicted by Human Splicing Finder [23 (link)]. All variants identified by the Illumina HiSeq X Ten sequencer were confirmed by Sanger sequencing. The pathogenicity of mutations was assessed in accordance with American College of Medical Genetics and Genomics guideline (ACMG) [9 (link)–11 (link)].

Freshly egressed tachyzoites were collected and purified through polycarbonate membranes with a pore size of 3 μm. Samples were washed with PBS, and total RNA was extracted using the TRIzol methods according to the manufacturer’s instructions (TransGen Biotech, Beijing, China). Three samples were independently prepared for each strain. Then, RNA libraries were constructed using the TruSeq RNA sample preparation kit (Illumina, San Diego, CA, USA) and sequenced with the Illumina HiSeq X Ten sequencer.
The raw sequencing reads were trimmed and quality controlled by SeqPrep and Sickle. Then, clean reads were mapped to the reference genome ME49 (downloaded from ToxoDB) using TopHat. To identify differentially expressed genes, the transcript level for each gene was calculated according to the fragments per kilobase of exon per million mapped reads (FPKM) method and then compared.
To validate the gene expression changes revealed by RNA-Seq, RNA samples were also subjected to quantitative RT-PCR analysis using the Fast SYBR method (Vazyme Biotech Co., Nanjing, China). Primers used are listed in Table S1. Expression of target genes was normalized to that of β-tubulin and then compared. Each sample was independently analyzed three times, each in triplicate.

Total genomic DNA was extracted from the flight muscle and testes using a Genomic‐tip 20/G kit (QIAGEN), following the manufacturer's protocol. The quality of DNA samples was assessed with Qubit (Thermo Fischer Scientific), NanoPhotometer (Implen), and 2200 TapeStation (Agilent) instruments. For genome assembly, the genomic DNA of an SI individual (SI03) was sent to GeneBay, Inc. (Yokohama) for library construction and long‐read sequencing using the ONT PromethION system (Oxford Nanopore Technologies). Short‐read sequencing was performed with 150‐bp paired‐end reads in three runs on an Illumina HiSeq X Ten sequencer (Illumina) at Macrogen Japan. For genome assembly, a single sample (SI03) was sequenced using one lane of the HiSeq X Ten sequencer. For resequencing, 10 samples from the SI and ER groups and 15 samples from the WR, SG, and SR groups were separately sequenced using two lanes of the HiSeq X Ten sequencer. Library construction for SI and ER samples was performed at Macrogen Japan and that for WR, SG, and SR samples was performed at Kyoto University using the NEB Next Ultra II FS DNA Library Prep Kit for Illumina (E7805S; New England Biolabs). Adapters on raw reads were trimmed using Porechop (v0.2.4, https://github.com/rrwick/Porechop) for ONT PromethION long reads and fastp (Chen et al., 2018 (link)) for Illumina HiSeq X short reads.

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.
