Introduction
Curcuma longa, commonly known as Turmeric, is a perennial native to India and Southeast Asia. The rhizomes are used as a coloring and flavoring agent in many Asian cuisines and for dyeing cloth a deep orange-yellow.
Methods
A single cultivated specimen was used for this study. DNA extraction was performed using the Qiagen DNAeasy genomic extraction kit using the standard process. A paired-end sequencing library was constructed using the Illumina TruSeq kit, according to the manufacturer’s instructions. The library was sequenced on an Illumina Hi-Seq platform in paired-end, 2 × 150bp format. The resulting fastq files were trimmed of adapter/primer sequences and low-quality regions with Trimmomatic v0.33 (Bolger, Lohse, and Usadel 2014). The trimmed sequences were assembled by SPAdes v2.5 (Bankevich et al. 2012) followed by a finishing step using Zanfona v1.0 (Kieras 2021) to make additional contig joins based on conserved regions in related species.
Results
The genome assembly yielded a total sequence length of 581,175,068bp.
