Plants must make decisions to balance their growth versus defense against pathogens. Signaling of the plant peptide hormone phytosulfokine (PSK) has emerged as a critical stimulus for growth promotion. In this issue of The EMBO Journal, Ding et al (2022) show that PSK signaling promotes nitrogen assimilation via phosphorylation of glutamate synthase 2 (GS2). In the absence of PSK signaling, the plants growth is stunted, but its resistance to disease is reinforced.
植物必须做出决策，在生长和防御病原体之间取得平衡。植物肽激素硫氧还蛋白（PSK）的信号转导已成为促进生长的关键刺激因素。在本期《欧洲分子生物学组织杂志》上，丁等人（2022 年）表明，PSK 信号通过谷氨酸合酶 2（GS2）的磷酸化促进氮同化。在没有 PSK 信号的情况下，植物的生长受到抑制，但对疾病的抵抗力增强。
