Effect of sodium hydrosulfide (NaHS), hypotaurine (HT), sodium nitroprusside (SNP), and 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1- oxyl-3-oxide (cPTIO) on L-cysteine desulfhydrase (LCD) (A), D-cysteine desulfhydrase (DCD) (C), O-acetylserine (thio) lyase (OAS-TL) (D) activities and corresponding gene expression (B, E) as well as hydrogen sulfide (H2S) content (F) in maize seedlings under non-HS conditions. The data had at least three biological replicates and were tested using Duncan's multiple-range test at 0.05 significant level, which denote means ± standard error (SE). The bars with the different letters represent significant differences, while the same letters represent no significant difference.
