Haplotype-resolved nonaploid genome provides insights into in vitro flowering in bamboos.

ABSTRACT: Woody bamboos (Bambusoideae) are renowned for its polyploidy and rare flowering. Bambusa odashimae is one of the bamboo species with the highest chromosome count (104) in the subfamily and has the highest heterozygosity of all sequenced bamboo genomes so far. Compared with other bamboo species, it can efficiently utilize exogenous hormones to regulate in vitro flowering, providing valuable insights into the hormonal regulation of bamboo flowering. Here, we generated the haplotype-resolved genome assembly of B. odashimae, despite the complexity and high chromosome number, supplemented by thirty-three transcriptomes from eleven developmental periods using a tissue culture system. The assembled genome can be divided into Haplotype I, Haplotype II, and Haplotype III, each
