a, Insertion burst of LTR retrotransposons of Gypsy and Copia. TE, transposable element. b–l, Multi-dimensional display of genomic components of Tu chromosome 1. b, DNA pseudomolecule. c, Gene frequency (number of genes per 10 Mb). d, Repeat density (per cent nucleotides per 5 Mb). e, Density of LTR retrotransposons (per cent nucleotides per 10 Mb). f, Frequency of lncRNA (log[number per 10 Mb]). g, Frequency of segmentally duplicated genes (log[number per 1 Mb]). h, Frequency of tandemly duplicated genes (log[number per 1 Mb]). i, Frequency of simple sequence repeats (log[number per 10 Mb]). j, Linkage map distance (cM per 5 Mb). k, Accumulated gene expression level (log2[FPKM (fragments per kilobase of transcript per million mapped reads) per 5 Mb]). l, GC content (per cent per 1 Mb).
