Table 1. Summary of GO and KEGG enrichment analyses in P. yayanosii.

Conditions	Genes		Proteins
	DR	UR	DR	UR
20 vs 52 MPa	Hydrogenases	Chemotaxis	Ribosomes	-tRNA bisynthesis -Oxidoreductase activity
80 vs 52 MPa	Hydrogenases	Ribosomes transmembrane ATPases	-Ribosomes-Formate metabolism	-tRNA biosynthesis-Hydrogenases

The hydrostatic pressure 52 MPa is considered as the reference condition whereas 20 and 80 MPa where considered the stressful conditions. UR means up-regulated and DR means down-regulated.
