Paramecium bursaria (Ehrenberg, 1831) species Accepted Name authority: UKSI Establishment means: Native. To assess the completeness of our genome assembly, we used the following criteria to filter the alignment of Core Eukaryotic Gene (CEG) sequences and our genome from BLASTP [56]. We assembled 614 contigs and removed 17 contigs derived from bacterial contamination judging from their GC content and similarity to bacterial sequences according to the NCBI database. DNA sequences of the intervals having at least four telomere-containing reads were extracted and subjected to motif analysis after removing the telomeric sequences. They may be passed from one generation to … Data were analyzed using the built-in analysis program. Relative impact of nucleotide and copy number variation on gene expression phenotypes.
