Overexpression of PSK-γ in Arabidopsis promotes growth without influencing pattern-triggered immunity.

Plant signaling & behavior - 1 Jan 2019

Abstract excerpt

Phytosulfokine-α (PSK-α) is a disulfated pentapeptide with the sequence YIYTQ. As a new peptide hormone, PSK-α promotes plant growth and development but represses pattern-triggered immunity (PTI) against bacterial pathogens. Our recent study identified a novel phytosulfokine, PSK-γ, from soybean. The sequence of PSK-γ is YVYTQ in which the tyrosines are sulfated. Expression of PSK-γ significantly increased seed...
