Study: Comparative analysis of nascent transcription among plant species
show Abstracthide Abstract
Comparative analysis of nascent transcription among plant species Overall design: A.thaliana Col-0 mature leaves were collected from plants grown as described (M. Wang et al. 2023), while A.thaliana Col-0 suspension cells were grown in 250-mL baffled flasks containing 50 mL of growth medium (3.2 g/L Gamborg's B-5 medium, 3 mM MES, 3% [v/v] Suc, 1.1 mg L-1 2,4-dichlorophenoxyacetic acid). The cultures were maintained at 23°C under continuous light on a rotary shaker (160 rpm) and kindly provided as a frozen pellet by Dr. Ashley M. Brooks. Barley (Hordeum vulgare) RNA was isolated by Dr. Pete Hedley from embryonic tissue (including mesocotyl and seminal roots; EMB) isolated from grain tissues 4 days past germination (Mascher et al. 2017). Physcomitrium (Physcomitrella) patens (Gransden) was grown on plates with BCDA medium in a growth cabinet at 21°C under 16h light. Selaginella moellendorffii was purchased from Plant Delights Nursery and grown at the window under normal daylight for 1 week prior to isolating RNA from stems and leaves. C. reinhardtii, which was kindly provided by Dr. Will Ansari and Dr. Stephen Mayfield (UC San Diego), was grown to late logarithmic phase in TAP (Tris–acetate–phosphate) medium at 23°C under constant illumination of 5000 lux on a rotary shaker. Adult 2nd and 3rd leaves from Z. mays L. cultivar B73 was kindly provided by Dr. Lauri Smith (UC San Diego). Plants were grown in 4-inch pots in a greenhouse (temp: 23°C-29°C) without supplemental lighting or humidification (humidity in the 15 hours following inoculation ranged between 70 and 90%) year round in La Jolla, CA. RNA from Z. mays L. cultivar B73 7d old shoot, root and leaves were grown in the Schmitz laboratory (University of Georgia) as described in (Ricci et al. 2019).

Name: GSM7439232
Instrument: Illumina NovaSeq 6000
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: cDNA
Layout: PAIRED
Construction protocol: csRNA-seq was performed as described in (S. H. Duttke et al. 2019). Small RNAs of ~20-60 nt were size selected from 0.4-3 µg of total RNA by denaturing gel electrophoresis. A 10% input sample was taken aside and the remainder enriched for 5'-capped RNAs. Monophosphorylated RNAs were selectively degraded by 1 hour incubation with Terminator 5´-Phosphate-Dependent Exonuclease (Lucigen). Subsequently, RNAs were 5'dephosporylated through 90 minutes incubation in total with thermostable QuickCIP (NEB) in which the samples were briefly heated to 75°C and quickly chilled on ice at the 60 minutes mark. Input (sRNA) and csRNA-seq libraries were prepared as described in (Hetzel et al. 2016) using RppH (NEB) and the NEBNext Small RNA Library Prep kit, amplified for 11-14 cycles. Total RNA-Seq Library Preparation Strand-specific, paired-end libraries were prepared from total RNA by ribosomal depletion using the Ribo-Zero Gold plant rRNA removal kit (Illumina, San Diego, CA). Samples were processed following the manufacturer's instructions.
