Moricandia is a genus belonging to the family Brassicaceae. C-3 and C-3-C-4 photosynthesis Moricandia species exist in a close phylogenetic proximity, as well as to Brassica crops. Here, we performed PacBio genome sequencing on M. moricandioides and M. arvensis. The genomes were assembled using Flye assembler, then polished with Illumina reads and reduced duplication with Purge Haplotigs. The total length of genome assemblies of M. moricandioides and M. arvensis was 498 Mbp and 759 Mbp, respectively. These data will be useful for studies of the genetic control of C-3-C-4 characteristics, therefore gaining new insights into the early evolutionary steps of C-4 photosynthesis. Further, it can be integrated into Brassica crop breeding. The data can be accessed at ENA under the project number PRJEB39764. (C) 2021 The Author(s). Published by Elsevier Inc
