Abstract

Some pathogens colonize plant leaves, but others invade the roots, including the vasculature, causing severe disease symptoms. Plant innate immunity has been extensively studied in leaf pathosystems; however, the precise regulation of immunity against vascular pathogens remains largely unexplored. We previously demonstrated that loss of function of the receptor kinase FERONIA (FER) increases plant resistance to the typical vascular bacterial pathogen Ralstonia solanacearum. Here, we show that upon infection with R. solanacearum, root xylem cell walls in Arabidopsis thaliana become highly lignified. FER is specifically upregulated in the root xylem in response to R. solanacearum infection, and inhibits lignin biosynthesis and resistance to this pathogen. We determined that FER interacts with and phosphorylates the transcription factor RESPONSIVE TO DESICCATION 26 (RD26), leading to its degradation. Overexpression and knockout of RD26 demonstrated that it positively regulates plant resistance to R. solanacearum by directly activating the expression of lignin-related genes. Tissue-specific expression of RD26 in the root xylem confirmed its role in vascular immunity. We confirmed that the FER–RD26 module regulates lignin biosynthesis and resistance against R. solanacearum in tomato (Solanum lycopersicum). Taken together, our findings unveil that the FER–RD26 cascade governs plant immunity against R. solanacearum in vascular tissues by regulating lignin deposition. This cascade may represent a key defense mechanism against vascular pathogens in plants.

FERONIA-RESPONSIVE TO DESSICATION 26 模块调节血管对茄属拉氏菌的免疫力
一些病原体在植物叶片上定植,但另一些则侵入根部,包括脉管系统,导致严重的病害症状。植物先天免疫在叶片病理系统中得到了广泛的研究;然而,针对维管病原体免疫的精确调控在很大程度上仍未得到探索。我们以前曾证实,受体激酶 FERONIA(FER)的功能缺失会增强植物对典型维管束细菌病原体 Ralstonia solanacearum 的抵抗力。在这里,我们发现当拟南芥感染 R. solanacearum 时,拟南芥根木质部细胞壁会高度木质化。FER 在根木质部中特异性上调,以应对 R. solanacearum 的感染,并抑制木质素的生物合成和对该病原体的抵抗。我们确定 FER 与转录因子 RESPONSIVE TO DESICCATION 26(RD26)相互作用并使其磷酸化,从而导致其降解。RD26的过表达和基因敲除表明,它通过直接激活木质素相关基因的表达,积极调节植物对茄碱菌的抗性。RD26 在根木质部的组织特异性表达证实了它在维管免疫中的作用。我们证实,FER-RD26 模块调控番茄(Solanum lycopersicum)的木质素生物合成和对 R. solanacearum 的抗性。综上所述,我们的研究结果揭示了 FER-RD26 级联通过调节木质素沉积,在维管组织中控制植物对茄红素菌的免疫力。该级联可能代表了植物对维管束病原体的一种关键防御机制。
