First De novo whole genome sequencing and assembly of mutant Dendrobium hybrid cultivar 'Emma White'.

ABSTRACT: The Dendrobium hybrid cultivar 'Emma White' is an ornamental, successfully commercialised orchid. We used a gamma ray-induced early flowering mutant and the Illumina HiSeqX10 sequencing platform to generate the first draft de novo whole genome sequence and assembly. The draft sequence was 678,650,699 bp in length, comprising 447,500 contigs with an N50 of 1423 and 33.48% GC content. Comparing 95,529 predicted genes against the Uniprot database revealed 60,741 potential genes governing molecular functions, biological processes and cellular components. We identified 216,232 simple sequence repeats and 138,856 microsatellite markers. Chromosome-level genome assembly of Dendrobium huoshanense was used to RagTag-scaffold available contigs of the mutant, revealing a total le
