Walnut anthracnose induced by is a disastrous disease that severely restricts the development of the walnut industry in China. Long non-coding RNAs (lncRNAs) are involved in adaptive responses to disease, but their roles in the regulation of walnut anthracnose resistance response are not well defined. In this study, transcriptome analysis demonstrated that a -induced lncRNA, lncRNA109897, located upstream from the target gene , upregulated the expression of . JrCCR4 interacted with JrTLP1b and promoted its transcriptional activity. In turn, JrTLP1b induced the transcription of to promote its expression. Meanwhile, transient expression in walnut leaves and stable transformation of further proved that lncRNA, JrCCR4, and JrTLP1b improve the resistance of . Collectively, these findings provide insights into the mechanism by which the lncRNA109897-JrCCR4-JrTLP1b transcriptional cascade regulates the resistance of walnut to anthracnose.
由[病原体名称未给出]引起的核桃炭疽病是一种灾难性病害，严重制约了中国核桃产业的发展。长链非编码RNA（lncRNAs）参与对疾病的适应性反应，但其在核桃炭疽病抗性反应调控中的作用尚不明确。在本研究中，转录组分析表明，一种由[病原体名称未给出]诱导产生的lncRNA，即lncRNA109897，位于靶基因[基因名称未给出]的上游，上调了[基因名称未给出]的表达。JrCCR4与JrTLP1b相互作用并促进其转录活性。反过来，JrTLP1b诱导[基因名称未给出]的转录以促进其表达。同时，在核桃叶片中的瞬时表达和[基因名称未给出]的稳定转化进一步证明，lncRNA、JrCCR4和JrTLP1b提高了[植物名称未给出]的抗性。总的来说，这些发现为lncRNA109897-JrCCR4-JrTLP1b转录级联调控核桃对炭疽病抗性的机制提供了见解。
