Sample GSM5195918 Query DataSets for GSM5195918
Status Public on Mar 08, 2023
Title EE501F2_093_C_T2_R1
Sample type SRA
 
Source name leaf tissue
Organism Solanum chacoense
Characteristics genotype: EE501F2_093
condition: Control
time: T2-48 hours after beetle placement
Treatment protocol For each genotype, two cages received adult Colorado potato beetles (treatment) and one cage did not receive beetles (control). Adult Colorado potato beetles were collected from untreated foliage of the commercial cultivar S. tuberosum ╘Atlantic╒ at the Michigan State University Montcalm Research Center (Lakeview, MI) on July 16th, 2019. Adult beetles were starved for 6 hours prior to being put on the experimental plants. When plants were 15-weeks old, 50 beetles were applied to treatment cages and leaf tissue was harvested for RNA isolation in the following time course: T0 = immediately preceding beetle placement; T1 = 24 hours after beetle placement; T2 = 48 hours after beetle placement. At each of the three timepoints, two biological replicates were prepared by pooling equal quantities of tissue from the third fully expanded leaf each genotype and condition (treatment or control) (N = 24). Total percent defoliation was visually determined for each treatment plant at T2
Growth protocol Six in vitro plantlets of each genotype (80-1 and EE501F2_093) (N = 12 plantlets) with good roots were transplanted to 6╙ pots in SUREMIXTM media (Michigan Grower Products Inc., Galesburg, MI). Two plants of each genotype were placed in individual RESTCLOUDTM mesh insect cages (15.3╙ wide x 15.3╙ deep x 23.6╙ long) (N = 6 cages) in a growth chamber maintained under 60% relative humidity, a 16 hr photoperiod, 16íC night and 20íC day temperature and 250 mE of light intensity. After two weeks, plants received 20-20-20 Peters Professional General Purpose Fertilizer (ICL-SF USA, Summersville, SC) at a rate of 500mg/l twice weekly.
Extracted molecule total RNA
Extraction protocol RNA was isolated using the Qiagen RNeasy Plant Mini Kit (Qiagen, Hilden, Germany). Samples were Turbo DNase (Thermo Fisher Scientific, Waltham, MA, USA) treated, and RNA quantity and quality was assessed using an Agilent 4200 TapeStation (Agilent Technologies Inc., Santa Clara, CA).
Libraries were prepared using the Illumina TruSeq Stranded mRNA Library Preparation Kit and approximately 30,000,000 50nt single-end Illumina reads were generated for each sample on the Illumina HiSeq 4000 platform.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 4000
 
Data processing Raw reads were processed with Trimmomatic (v0.35) (MINLEN = 36, LEADING = 20, TRAILING = 20) to remove low-quality bases, adapters, and primers (Bolger et al., 2014).
Cleaned reads were aligned to the potato doubled monoploid S. tuberosum clone DM1-3 516 R44 (DM) pseudomolecules (PGSC Version 6.1) using STAR (v2.7.3a) (Dobin et al., 2013).
Alignments for each sample generated from separate Illuminia lanes were merged using the Picard tool MergeSamFiles (v2.18.27-Java-1.8) (broadinstitute.github.io/picard).
Reads aligning to annotated DM reference genes were counted using HTSeq in union mode (v0.11.2) (Anders et al., 2015).
