Bubbles representing different comparison groups of liquorice roots following differential protein KEGG enrichment. Note: The horizontal coordinate in the graph is the ratio of the number of differential proteins in the corresponding pathway to the number of total proteins identified in that pathway; the larger the value, the higher the differential protein enrichment in that pathway. The colour of the dot represents the P value of the hypergeometric test; the colours range from blue to red, the redder the colour, the smaller the value and the more reliable and statistically significant the test is. The size of the dots represents the number of differential proteins in the corresponding pathway, the larger the dot, the more differential proteins are present in the pathway
