[H.sub.2]S is produced by cystathionine [beta]-synthase, cystathionine [gamma]-lyase, L-cysteine desulfhydrase, and 3-mercaptopyruvate sulfurtransferase (for an overview see [1] and references within).
In plants, [H.sub.2]S is mainly produced via the L-/D-cysteine desulfhydrase enzymes (LCD/ DCD) and it has been reported to be involved in stress responses to drought, heat, heavy metal and salt during seed germination and seedling growth (ZHANG et al., 2010a; JIN et al., 2011; LAI et al., 2014; LI et al., 2014).

The [Pb.sup.2+] could combine with the glycoproteins of cell walls, and then was transmitted into cytoplasm which contained [S.sup.2-] generated by assimilation of sulfate reduction and the effect of cysteine desulfhydrase, and then synthesized PbS precipitation with [S.sup.2-] in the cytoplasm, eventually moved out of the cell (11).
