Examples of VitB6 De Novo and Salvage Pathway Mutants in Context with Stress.

Organism	Mutant	Pathway affected	Phenotype	Citation
E. coli	ppox/pdxH	Salvage	Reduced growth, aberrant shape	[27]
C. nicotianae	sor1/pdx1	De novo	Increased ROS sensitivity, loss of vitB6 production, increased salt sensitivity, reduced growth	[81]
S. cerevisiae	snz1/pdx1	De novo	Reduced growth in minimal media	[94]
S. cerevisiae	sno1/pdx2	De novo	Reduced growth in minimal media	[94]
S. cerevisiae	pdx3	Salvage	Increased ROS sensitivity	[50]
A. thaliana	sos4-1	Salvage	Increased salt sensitivity	[87, 90]
A. thaliana	pdx 1.1, pdx 1.3	De novo	Increased salt sensitivity	[21, 86]
A. thaliana	pdx3/PPOX	Salvage	Reduced aerial & root growth, increased salt sensitivity	[50, 90]
