TL;DR

This paper presents the genome sequencing and assembly of Bambusa tulda, a commercially important bamboo species, providing a valuable resource for future research.

Contribution

The study provides the first de novo genome assembly of Bambusa tulda using long-read sequencing, offering insights into its genetic structure and function.

Findings

The genome assembly consists of 43 contigs across three subgenomes with a total length of 1.37 Gb.

Functional annotation identified 56,890 protein-coding genes, covering 19.44% of the genome.

Abstract

Bambusa tulda Roxb., a member of the Bambusoideae subfamily, is an ecologically and commercially important plant resource widely distributed in the Indian subcontinent. Our study reports long-read PacBio HiFi sequencing and genome assembly of B. tulda. The de novo haploid genome assembly of B. tulda predicted 43 contigs, distributed across three subgenomes, with a total sequenced length of 1.37 Gb, contig N50 of 35.69 Mb, and BUSCO score 99%. Repetitive elements constitute 63.31% of the genome. Functional annotation predicted 56,890 protein-coding genes, constituting 19.44% of the genome. This genome sequence will serve as an invaluable resource for future studies on the life history traits, phylogenomic analysis, comparative genomics, and targeted genome modification for important trait improvement of B. tulda.
