Interaction of sulfur with phytohormones and signaling molecules in conferring abiotic stress tolerance to plants

Figures & data

Figure 1. Interaction of S with phytohormones and other signaling molecules in the signaling cascade to combat abiotic stresses. Here, GSH plays a central role which interacts with NO and produce GSNO to provide signal. GSH is also actively involved in metal chelation and also regulates antioxidant defense system. NO is directly interacted with H₂S which further modulates several molecules and their functions. Cysteine is one of the major S-containing amino acids which is interacted with several phytohormones and also regulates PAs and other molecules via several pathways. Dotted lines represent activation or enhancement. Additional details are in text.
