Fig. 3

The genome Circos and KEGG functional prediction for P. distasonis F4. A The Circos plot represents the genome structure. The outermost circle indicates the genome size. The second and third circles represent the CDSs on the positive and negative strands, respectively, with different colors denoting different COG functional classifications of the CDSs. The fourth circle marks rRNA and tRNA. The fifth circle depicts GC content, with red sections indicating regions with GC content above the genome-wide average (higher peaks indicate greater deviation), and blue sections indicating regions below the average (higher peaks indicate greater deviation). The innermost circle represents the GC-Skew value, calculated as (G − C)/(G + C). B The left side shows KEGG Level 2 pathway classification, with the y-axis representing the Level 2 categories of KEGG pathways and the x-axis indicating the number of genes annotated under each category. The right side provides a detailed exhibition of the Level 3 classifications within the major metabolic pathways of carbohydrate metabolism and amino acid metabolism. C Predicted pathways for acid production are shown. Red circles represent present genes, blue circles represent absent genes, and dashed lines indicate blocked pathways
