design: Genomic DNA was extracted from young leaves of Psophocarpus tetragonolobus (cultivar AKWB-1) and used to construct a whole genome sequencing library with the TruSeq DNA PCR-Free Library Prep Kit (Illumina, catalog no. 20015963), following the manufacturer's protocol. The library was prepared using random shearing without enrichment or amplification steps. The paired-end library was sequenced on the Illumina platform to generate data for nuclear, mitochondrial, and chloroplast genome analysis.
