Boldface P values are <0.05, supporting the null hypothesis in the header row. Italic P values are >0.95, supporting the alternative hypothesis. The percentages of the different ORFan groups of HGT origin are calculated as, e.g., % PS-ORFans = no. of horizontally transferred PS-ORFans/total no. of horizontally transferred ORFans in genome.
