The telomere-to-telomere (T2T) genome provides insights into the evolution of specialized centromere sequences in sandalwood.

ABSTRACT:

Background

Sandalwood, a prized hemiparasitic plant, is highly sought in the commercial market because of its aromatic core materia. The structure and stability of the genome are instrumental in the rapid adaptation of parasitic plants to their surroundings. However, there is a conspicuous lack of research on the genomic-level adaptive evolution of sandalwood.

Results

In this study, we assembled a gap-free telomere-to-telomere (T2T) reference genome for Santalum album using PacBio HiFi, Hi-C, and ultra-long ONT data. The T2T reference genome (Sal_t2t) encompassed annotations of 24,171 genes and 25.34% repetitive sequences, in addition to all 10 centromeres and 20 telomeres across the 10 chromosomes. The results revealed that the 3 distinct parasitic species of Santalales had
