ersion of PC99, for all downstream comparative evaluation. Sequencing gaps of PF40 (n = 180) and PC02 (n = 342) were uniquely aligned and filled by the corresponding Illumina sequences using BLASTN. Flow cytometry and K-mer analysis. Flow cytometry65 (CyFlow Cube, Partec, Germany) was applied to estimate genome size on the allotetraploid PF40. Fresh young leaves (300 mg) of PF40 were finely chopped with a razor blade in buffer of CyStain Absolute T. Immediately after extraction, the option was filtering via 30 nylon meshes, then 50 of RNase and propidium iodide (PI) had been added instantly. Rice (Oryza sativa sp. Japonica Nipponbare, 394.six Mb) was ready following precisely the same process as reference, and mixed with perilla extracts. Signals have been detected with an air-cooled argon laser (Uniphase) at 488 nm, 20 mW. Perilla genome size was estimated in accordance with the equation: 1C nuclear DNA content material = (1C PDE11 site reference genome size peak suggests of perilla)/(Peak mean of reference). We estimated genome sizes on the 3 perilla lines applying K-mer frequency evaluation using a K-mer size of 91 following published protocol66. Evaluation of assembly good quality. We evaluated assembly completeness using BUSCO67 v3.02 beneath genome mode (Supplementary Table 8). RIPK1 Accession Expressed sequence tags (ESTs) downloaded from GenBank (as of 1 Oct, 2019) and published perilla RNA-seq transcripts12,17 were mapped onto the PF40 genome applying BLASTN with default parameters. Raw Illumina paired-end reads have been mapped onto each cognate genome assembly applying BWA68 v0.7.10-r789. Repeat and gene annotation. Repetitive sequences with the 3 perilla genomes were identified by a mixture of homology-based and de novo approaches. Tandem repeats have been predicted employing Tandem Repeats Finder69 v4.07b. For transposable components, we first utilized RepeatMasker with all the Repbase70 v21.04 database of known repeats to search for transposable elements within the genomes, then RepeatProteinMask v4-0-6 was made use of by aligning the genomes to known repeat protein database. RepeatModeler v1-0-8 was run with default parameters for de novo prediction. Ultimately, repetitive sequences identified by unique procedures were combined in to the final repeat dataset (Supplementary Fig. 6 and Supplementary Data 1). LTR-RTs were further identified by LTR_retriever71. Given that direct repeats of a newly inserted LTR-RT are identical to each and every other, we made use of this identity worth to extrapolate the age of LTRs, and plotted them based on LTR correspondence in between PFA and PC02 (Supplementary Fig. 7). The ab initio gene predictions had been performed with 3 applications, including Augustus v3.0.3, GenScan v1.0, and Glimmer v3.02. We further utilized annotated proteins from seven published plant genomes, which includes Mimulus guttatus, Sesamum indicum, Solanum lycopersicum, Solanum tuberosum, Vitis vinifera, Brassica rapa, and Arabidopsis thaliana, for homology-based gene prediction with GeneWise v2.two.0. Lastly, we utilized two sets of RNA-seq assembly data downloaded from ref. 12 (de novo transcriptome assembly from four mRNA samples of perilla seeds at different developmental stages, with 54,079 transcripts) and ref. 17 (from whole transcriptome of red and green types of perilla leaves with 54,500 and 54,445 transcripts, respectively), collectively with 5538 perilla ESTs downloaded from GenBank, for RNA-Seq-based gene prediction with Augustus v3.0.three. Combination of those final results using EVidenceModeler72 v1.1.1 generated high-quality annotations of the three genomes, whi
