As per [10 (link)], (a) amplification of full length 16S ribosomal gene (1464 bp) from 50 ng/μl DNA from each CP sample using V1-V9 variable region primers; (b) barcoding of each amplified amplicon using paired 16-nt symmetric barcodes (https://github.com/PacificBiosciences/Bioinformatics-Training/wiki/Barcoding-with-SMRT Analysis-2.3) (Table 1); (c) multiplexing of barcoded-purified amplicons in a group of 5 libraries (Supplementary Table 2); and (d) Sequencing using DNA Sequencing Reagent Kit 4.0 v2 (Pacific Biosciences, USA) in a total of 24 SMRT cells (3 cells/library) using 6-hour movies data collection protocol were performed.
