Abstract Chloroplasts and mitochondria are the primary sites for photosynthesis and respiration, each harboring its own unique genome. Although the organellar genomes are considerably smaller compared to the nuclear genome, they are nonetheless essential for survival of the organism. A common feature of many chloroplast and mitochondrial genomes is the presence of large repeated sequences longer than 1 kb.

Seventy-three HiFi-based assemblies and read sets, representing 71 natural accessions, were obtained from seven public sources. The datasets of 44 accessions were from Wlodzimierz et al. [35]. 11 from Kang et al. [58], 14 from Lian et al. [59], the Kew-1 accession from Christenhusz et al. [60], and three independent Col-0 datasets from Rabanal et al. [43], Wang et al. [30], and Naish et al. [31]. Three HPG1 accessions [61] were sequenced with one SMRT Cell on the Sequel II platform (PacBio).

Abstract Telomeric repeat arrays at the ends of chromosomes are highly dynamic but their repetitive nature and technological limitations have made it difficult to assess the variation in genome diversity surveys. Here we present a comprehensive characterization of the sequence variation immediately adjacent to the canonical telomeric repeat arrays at the very ends of chromosomes in 49 genetically diverse Arabidopsis thaliana accessions.
