genecontent
Gene content refers to the set of genes annotated within a genome, or the combined gene content across a group of related genomes. It emphasizes coding potential and functional repertoire rather than base-pair length or sequence composition. Gene content can be influenced by annotation quality, assembly contiguity, and the criteria used to classify a sequence as a gene, including whether pseudogenes or noncoding genes are counted.
In comparative genomics, gene content is analyzed by grouping genes into orthologous families and comparing their
Applications of gene-content analysis include identifying essential genes, understanding adaptation and niche specialization, tracing evolutionary histories,
Related concepts include core genome, accessory genome, dispensable genes, and pan-genome, all of which describe different
