Ental and terrestrial adaptation genes. The salient structural variation in genes with respect for the particular traits for environmental and terrestrial adaptation which includes locomotion, immunity, osmoregulation, ionic balance, vision, olfaction, detoxification of xenobiotic compounds, and so on. that distinguished C. magur from other fishes were identified and discussed. The genome sequence information and facts of this species represents a vital resource and understanding to create genomic choice methods to overcome the problems linked with this valuable catfish as well as to increase both the fundamental as well as the applied research in C. magur also as other important catfish species.2. Components and methods2.1. Fish specimenFor whole genome sequencing, a farm bred and reared healthier male SGLT1 Accession specimen of C. magur from ICAR-Central Institute of Freshwater Aquaculture (CIFA), Bhubaneswar, India, was chosen. The fish was anesthetized plus the testes samples were collected in September 2013. Handling of fish was carried out following the suggestions for manage and supervision of experiments on animals by the Government of India and approved by Institutional Animal Ethics Committee (AEC) of ICAR-National Bureau of Fish Genetic Resources (NBFGR) and ICAR-CIFA. For genome size estimation methodology please see Supplementary note 1.1.2.2. Genome sequencingHigh molecular weight genomic DNA was extracted employing typical phenol hloroform extraction CaMK II drug method15 at ICAR-CIFA. A multiplatform (short, medium and log reads) sequencing technique was adopted to produce around 180-fold NGS information on 5 distinct NGS platforms. Helpful NGS data utilized in the genome assembly is presented in Table 1. Short sequencing methodology is provided in Supplementary note 1.two.2.3. De novo genome assemblyPre-processing of the raw reads/data of Illumina, Roche 454 and Ion Torrent (which includes filtering and removal of low-quality bases and reads with adaptor contamination) was carried out using NGSQC Toolkit16 to receive a set of high-quality usable reads, though pre-processing of NanoporeMinIon and PacBio data was completed applying in-built function of MaSuRCA software program Version 3.2.9.17 The de novo genome assembly was carried out by way of a hybrid method following a pipeline using each brief and long reads generated from various NGS platforms (Fig. 1). Initially, the assembly was carried out on MaSuRCA software program utilizing both long and brief reads data. The PacBio and Nanopore MinIon reads were supplied as NanoporeMagur genome unveils genetic basis of adaptationTable 1.
