Genomic DNA was isolated from B. juncea seedlings using CTAB method [59] . The quality and quantity of the extracted DNA was assessed by electrophoresis on a 0.8% agarose gel and spectrophotometer (Biorad, USA), respectively. Three μg gDNA was used to prepare a genomic DNA library utilizing Illumina DNA sample preparation kit according to manufacturer’s instructions. High-throughput pair-end sequencing (2×75 cycles) was performed on Illumina GA IIx sequencer at University of Delhi South Campus, India. High quality reads were assembled through Velvet/Oasis assemblers [60] (link), [61] (link).
