Telomere-to-telomere genome of common bean (Phaseolus vulgaris L., YP4).

ABSTRACT:

Background

Common bean is a significant grain legume in human diets. However, the lack of a complete reference genome for common beans has hindered efforts to improve agronomic cultivars.

Findings

Herein, we present the first telomere-to-telomere (T2T) genome assembly of common bean (Phaseolus vulgaris L., YP4) using PacBio High-Fidelity reads, ONT ultra-long sequencing, and Hi-C technologies. The assembly resulted in a genome size of 560.30 Mb with an N50 of 55.11 Mb, exhibiting high completeness and accuracy (BUSCO score: 99.5%, quality value (QV): 54.86). The sequences were anchored into 11 chromosomes, with 20 of 22 telomeres identified, leading to the formation of 9 T2T pseudomolecules. Furthermore, we identified repetitive elements accounting for 61.20% of the genome a
