Chromosome-Scale Genome Assembly of the Resurrection Plant Acanthochlamys bracteata (Velloziaceae)

Acanthochlamys bracteata (Velloziaceae) is a resurrection plant with cold tolerance. Herein, a chromosome-level reference genome of A. bracteata based on Nanopore, Illumina, and Hi-C data is reported. The high-quality assembled genome was 197.97 Mb, with a scaffold N50 value of 8.64 Mb and a contig...

Sumario:Acanthochlamys bracteata (Velloziaceae) is a resurrection plant with cold tolerance. Herein, a chromosome-level reference genome of A. bracteata based on Nanopore, Illumina, and Hi-C data is reported. The high-quality assembled genome was 197.97 Mb, with a scaffold N50 value of 8.64 Mb and a contig N50 value of 6.96 Mb. We annotated 23,509 protein-coding genes. Eight contracted gene families and three expanded gene families were detected. Repeat sequences accounted for approximately 28.63% of the genome. The LEA1 and Dehydrin gene families, which are involved in desiccation resistance, expanded in A. bracteata. We identified genes involved in chilling tolerance, COLD1.
