Fig. 1

Circular map of Oenococcus oeni SD-2a genome. The outermost circle of the circle graph is an indicator of the size of the genome. The second and third circles are genes on positive and negative chains; different colors represent the functional classification of COGs with different genes. The fourth circle is rRNA and tRNA. The fifth circle is GC content; the outward red part indicates that the GC content in this region is higher than the average GC content of the whole genome, the inward blue part indicates that the GC content in this region is lower than the genome-wide average GC content, the higher the peak value, the greater the difference from the average GC content. The innermost circle is the GC skew value; the outward red part indicates that the value is positive, the inward blue part indicates that the value is negative.

Venn diagram showing the number of unique and homologous gene clusters in Oenococcus oeni SD-2a, Oenococcus oeni PSU-1, Oenococcus oeni CRBO-11381, Lactiplantibacillus plantarum UNQLp11, and Pediococcus pentosaceus KCCM40703. The histogram shows each strain’s total gene clusters involved in homologous gene analysis.
