Chromosome-level assemblies of two hexaploid bamboos, Thyrsostachys oliveri and Thyrsostachys siamensis, provide a foundation for functional and comparative genomics studies.

ABSTRACT:

Background

Bamboo is an important nontimber forest resource with significant ecological and economic value. However, genomic resources for several bamboo lineages remain scarce.

Results

We present the first chromosome-scale genome assemblies for 2 economically important Thai woody bamboos, Thyrsostachys oliveri and Thyrsostachys siamensis. Using single-tube long-fragment read (stLFR) sequencing integrated with chromosome conformation capture (Hi-C) scaffolding, we assembled 35 pseudochromosomes spanning 990 Mb (N50 = 22.18 Mb) for T. oliveri and 1.14 Gb (N50 = 19.45 Mb) for T. siamensis. The T. oliveri and T. siamensis genome assemblies contain 51,191 and 67,483 predicted genes, with repeat contents of 50.9% and 48.8%, respectively. BUSCO completeness scores reached 97.4% fo
