Comment

The assembly ddMerAnnu1.1 is based on 58x PacBio data, 10X Genomics Chromium data, and Arima2 Hi-C data generated by the Darwin Tree of Life Project (https://www.darwintreeoflife.org/). The assembly process included the following sequence of steps: initial PacBio assembly generation ... with Hifiasm, retained haplotig separation with purge_dups, short-read polishing using FreeBayes-called variants from 10X Genomics Chromium reads aligned with LongRanger, and Hi-C based scaffolding with YaHS. The ${ORGANELLE_TYPE_CLAUSE} assembled using MitoHiFi. Finally, the assembly was analysed and manually improved using gEVAL. Chromosome-scale scaffolds are named by synteny based on PMID:31113811. Chromosome assignment for this assembly has been based on the genetic map produced by Veltsos P et al. Early Sex-Chromosome Evolution in the Diploid Dioecious Plant Mercurialis annua. Genetics. 2019 Jul;212(3):815-835. PMID: 31113811. Owing to the sex chromosomes being homomorphic and recombining over an extensive autosomal region they were identified as a single linkage group. Therefore for this diploid female specimen X has been assigned LG1-X.  more
