Summary taken from our paper “Aspergillus terreus Sectorization: A Morphological Phenomenon Shedding Light on Amphotericin B Resistance Mechanism”: WT and ATSec strains were grown in AMM broth for 30 h at 30 °C. Afterwards, the cultures were subjected to either DMSO (control) or 1 µg/ml AmB treatment for 1 h/4 h. Triplicates of each combination of these factors were made, resulting in a total of 24 samples. RNA was extracted with a Promega GmbH kit (Madison, Wisconsin, USA) following the manufacturer's instructions. The RNA-seq experiment was conducted by BGI, generating a total of around 20 million 100bp paired-end reads with the DNBSEQ platform. BGI employed SOAPnuke (51) to remove rRNA, adaptor-containing sequences, low quality reads, and reads with high unknown nucleotide content, producing "clean reads" datasets that were used in the analysis. On average, clean read datasets contain 45.1 Mb of reads, while the raw read datasets contain 48.7 Mb. For clean reads, the mean Q20 value is 98.3%, and the mean Q30 value is 92.5%. Overall design: RNA-seq data from Aspergillus strain 211 and its sectorized derivative were analyzed in their gene expression pattern difference in the presence and absence of AmB. Each condition was analyzed in triplicates
Sample: Aspergillus terreus strain 211 sectorized derivative, control after 4h triplicate 1

Construction protocol: RNA was extracted with a Promega GmbH kit (Madison, Wisconsin, USA) following the manufacturer's instructions. Library construction according to BGI, the company performing the RNA-sequencing: The first step in the workflow involves purifying the poly-A containing mRNA molecules using poly-T oligo-attached magnetic beads. Following purification, the mRNA is fragmented into small pieces using divalent cations under elevated temperature. The cleaved RNA fragments are copied into first strand cDNA using reverse transcriptase and random primers. This is followed by second strand cDNA synthesis using DNA Polymerase I and RNase H. These cDNA fragments then have the addition of a single 'A' base and subsequent ligation of the adapter. The products are then purified and enriched with PCR amplification. We then quantified the PCR yield by Qubit and pooled samples together to make a single strand DNA circle (ssDNA circle), which gave the final library. DNA nanoballs (DNBs) were generated with the ssDNA circle by rolling circle replication (RCR) to enlarge the fluorescent signals at the sequencing process. The DNBs were loaded into the patterned nanoarrays and pair-end reads of 100 bp were read through on the DNBseq platform for the following data analysis study. For this step, the DNBseq platform combines the DNA nanoball-based nanoarrays and stepwise sequencing using Combinational Probe-Anchor Synthesis Sequencing Method.
