Breakdown of sulfur-related genes expressed differentially depending on sulfur supply

Sulfur source	Notation in texta	No. (%) of differentially expressed genes under high- vs low-sulfur conditions
All sulfur sources	H/L(M,C,S)	23 (47)
Methionine and cystine	H/L(M,C)	7 (14)
Methionine and sulfate	H/L(M,S)	1 (2)
Cystine and sulfate	H/L(C,S)	0 (0)
Methionine only	H/L(M)	17 (35)
Cystine only	H/L(C)	0 (0)
Sulfate only	H/L(S)	1 (2)

^aH, high; L, low; M, methionine; C, cystine; S, sulfate.
