A chromosome-level genome assembly of a model conifer plant, the Japanese cedar, Cryptomeria japonica D. Don.

ABSTRACT:

Background

The Japanese cedar (Cryptomeria japonica D. Don) is one of the most important Japanese forest trees, occupying approximately 44% of artificial forests and planted in East Asia, the Azores Archipelago, and certain islands in the Indian Ocean. Although the huge genome of the species (ca. 9 Gbp) with abundant repeat elements may have represented an obstacle for genetic analysis, this species is easily propagated by cutting, flowered by gibberellic acid, transformed by Agrobacterium, and edited by CRISPR/Cas9. These characteristics of C. japonica recommend it as a model conifer species for which reference genome sequences are necessary.

Results

Herein, we report the first chromosome-level assembly of C. japonica (2n = 22) using third-generation selfed progeny (estimat
