The experiment includes the effect of lsr2 and lsrL deletions on the local and global chromosome architecture.biostudies-arrayexpressSequencing - The agarose purified Hi-C libraries were diluted to 10 nM concentration, pooled together, and sequenced using Illumina NextSeq500 (2x75 bp; paired-reads) offered by Fasteris SA sequencing facility.Sample Collection - For preparation of S. venezuelae Hi-C contact maps, the standardized “small cultures” were setup. The cultures were incubated for 18 hours at 30˚C with shaking (180 rpm). After this time, the cultures were cross-linked with 1% formaldehyde for 7 minutes and 30 seconds, and blocked with 0.2 M glycine for 15 minutes. 1.2 ml of the cross-linked culture was centrifuged (1 minute, 5000 rpm at room temperature). The mycelium pellet was washed twice with 1.2 ml of TE buffer and resuspended in 0.6 ml of TE buffer.Nucleic Acid Extraction - Two vials, each containing 25 µl of the resuspended mycelium, were independently processed according to the modified protocol of Le*. Briefly, the cells were lysed using 0.5 µl of ReadyLyse solution (Invitrogen) at 37˚C for 30 minutes followed by the addition of 1.25 µl of 5% SDS solution and incubated at room temperature for 15 minutes. After cell lysis, the reaction was supplemented with 5 µl of 10% Triton X-100 (Sigma Aldrich), 5 µl of NEB3 buffer (New England Biolabs) and 10.75 µl of DNase-free water (Invitrogen), and subsequently incubated for 15 minutes at room temperature. The chromosomal DNA was digested with 2.25 µl of BglII restriction enzyme (New England Biolabs; 50000 U/mL) for 2 hours and 30 minutes at 37°C followed by the addition of 0.25 µl of BglII, and incubation for another 30 minutes at 37°C. * Chromosome Conformation Capture with Deep Sequencing to Study the Roles of the Structural Maintenance of Chromosomes Complex In Vivo.
