Dynamics and distribution of eccDNA in Arabidopsis. Left: Schematic representation of eccDNA amplification and sequencing via CIDER-Seq pipeline. Top right: EccDNA size distribution in Arabidopsis Col-0 leaf tissues (n = 4,158). The x-axis shows eccDNA size in kb and the y-axis shows the percentage of eccDNAs belonging to each window. Middle right: Size ranges of eccDNAs with marked median and quantiles (n = 4,190). Bottom right: Percentages of eccDNA reads mapping to TAIR CDS, TE, or intergenic databases (values represent the average of three replicates).
Previous studies of extrachromosomal circular DNA #eccDNA in #plants are based on short-read seq. @vanderschuren-lab.bsky.social uses long-read seq to obtain a map of full-length eccDNAs from #Arabidopsis, identifying their genomic origins & epigenetic regulation @plosbiology.org 🧪 plos.io/44Mq3RI
