Minor (U12-type) intron metadata for thousands of eukaryotic genomes

Information about minor introns and their containing genes for thousands of eukaryotic genomes. <br> The columns in the file are: Species: full species name Abbreviation: species name abbreviation Kingdom/phylum: taxonomic info as assigned by NCBI Accession: associated accession ID (dependent on source) Assembly: assembly ID Tax. ID: taxonomic ID (NCBI) Minor intron density (%): percentage of annotated introns which are minor (U12) type Total minor introns: number of annotated minor introns Total introns: total number of annotated introns Corrected minor introns: introns with non-canonical boundaries in the original annotations which contain strong minor-like motifs nearby, "corrected" to the new boundaries; may be enriched for false positives depending on annotation quality BUSCO (%): complete BUSCO score Confident call: "u12-" = confidently lacking minor introns, "u12+" confidently containing minor introns; integrates information about BUSCO score and the presence/absence of minor snRNAs Minor snRNAs: names of any minor snRNAs found in the genome Intron position MWU p-value: the p-value of a two-sided Mann-Whitney U test between major and minor intron positions within their containing genes Median minor intron position: the median position of minor introns within their containing genes Median major intron position: as above, for major introns Median MIG length: the median length (bp) of minor intron-containing genes (sum of the coding sequences) Median non-MIG length: as above, for genes without minor introns Median minor intron length (bp) Median major intron length (bp) Intron length MWU p-value: the p-value of a two-sided Mann-Whitney U test between the lengths of major and minor introns Genome retrieval date Annotation retrieval date<br>
