Phytosulfokine-α, a sulfated pentapeptide, stimulates the proliferation of rice cells by means of specific high- and low-affinity binding sites

Peptide growth factors were isolated from conditioned medium derived from rice (Oryza sativa L.) suspension cultures and identified to be a sulfated pentapeptide [H-Tyr(SO(3)H)-Ile-Tyr(SO(3)H)-Thr-Gln-OH] and its C-terminal-truncated tetrapeptide [H-Tyr(SO(3)H)-Ile-Tyr(SO(3)H)-Thr-OH]. These structu...
