A high-quality chromosome-level genome assembly of the traditional Chinese medicinal herb Zanthoxylum nitidum

Transcriptomic data from seven different tissues of Z. nitidum were collected to unveil the functional patterns of the BBE family in the biosynthesis of benzophenanthridine alkaloids The samples in this study were collected from 3-years-old individual plants grown at an artificial planting base in Nanning City, Guangxi Province (109°11′E, 22°31′N). The plant was identified by Prof. Yudeng Peng (Guangxi Botanical Garden of Medicinal Plants, China). This study utilized tissue materials from fresh leaves, fruits, roots, and stems for genomic and transcriptomic investigations, with three independent biological replicates collected for each sample type. The root tissues were categorized based on their size into large roots (≥ 3 cm in diameter), medium roots ( ≥ 2 cm and < 3cm in diameter), and small roots (≥1 and <2 cm in diameter). The stems were classified based on their size into old stems (≥3 cm in diameter) and tender stems (≥1 and <3 cm in diameter).
