The telomere‐to‐telomere gap‐free genome of four rice parents reveals SV and PAV patterns in hybrid rice breeding

Overview of four genomes and PAV patterns in hybrid rice. (a) Four indica pedigree and agronomic traits. (b) Overview of the four rice genomes. (c) Statistics of the assembly features for four genomes. (d) Number of SVs between NIP and ten indica genomes. (e) Venn diagram of genes that six hybrid combinations of complementary utilization affected by PAV. (f) OsHSP23.7 gene overview of SV and IGV. Using 500-kb intervals, the GC content, gene, TE, SNP, and InDel density were counted in the genomes (Figure 1b). According to analysis, among 593–738 complementary genes in the six combinations, and only 46 genes are utilized by all three types of combinations, and 213–274 genes are utilized (Figure 1e).
