The plant hormone salicylic acid plays an important role in balancing plant immunity and growth. In this issue of Cell Host & Microbe, Liu et al. (2022) discovered that a long non-coding RNA, lncSABC1, promotes growth in uninfected plants and unleashes defenses when pathogens attack by transcriptionally regulating salicylic acid biosynthesis.

LncRNA 进入平衡阶段

植物激素水杨酸在平衡植物免疫和生长方面发挥着重要作用。在本期《细胞宿主与微生物》中，刘等人。(2022) 发现长链非编码 RNA lncSABC1可促进未受感染植物的生长，并在病原体攻击时通过转录调节水杨酸生物合成释放防御能力。
