title: GSM1684590: Chlamydomonas reinhardtii, replicate 1 (4A+, 48h post Nitrogen depletion); Chlamydomonas reinhardtii; OTHER
library_construction_protocol: C. reinhardtii wild type strain 4a+ were cultured using Tris-acetate-phosphate (TAP) medium in Erlenmeyer flasks at 25 degrees Celsius with agitation at 180 rpm under light irradiation at 100 microE. Cells were washed twice with nitrogen-free media and re-suspended to a density of 2 x 106 cells/ml and harvested at 48 hr post starvation. Cells were lysed using lysis buffer (50mM Tris-HCl pH 8, 200mM NaCl, 2mM EDTA, 2% SDS and proteinase K) and genomic DNA was extracted using CTAB-based protocol39. 5-10ug of gDNA was sheared to >10kb using g-tube (Covaris). The sheared DNA was treated with DNA damage repair mix followed by end repair and ligation of SMRT hairpin adapters using SMRTbell Template Preparation Reagent Kit (Pacific Biosciences). Fragments without adaptors are digested with exonuclease. Libraries were sequenced on Pacific Biosciences RSII sequencer using standard protocols.
