The transcript ratios of phage:host gene pairs related to the four categories of P-acquisition AMGs in individual samples. Each circle in the panel represents a sample and is colored according to its habitat type. RPKM, reads per kilobase per million mapped reads. Detailed information on the public metatranscriptomes used to generate the results in ( b ) and ( c ) was provided in Supplementary Data 18 , while the numbers of the samples where these P-acquisition AMGs were detected are shown in Supplementary Data 19 .
