组蛋白去乙酰化酶(HDAC)是重要的表观遗传修饰因子,不仅在调节植物的发育,而且在非生物和生物胁迫反应。HD 2C是一种HD2型HDAC,目前已对其在植物发育和非生物胁迫中的功能进行了深入研究,但其在生物胁迫中的功能尚不清楚。在这项研究中,我们已经确定了HD 2C作为花椰菜花叶病毒(CaMV)P6蛋白的相互作用伙伴。它在抵抗CaMV感染中起正调节作用。hd 2c突变体显示出对CaMV感染的增强的易感性。作为支持,在hd 2c突变体中,病毒DNA、病毒转录物和组蛋白乙酰化在病毒微型染色体上的沉积增加。P6干扰HD 2C和HDA 6之间的相互作用,并且P6过表达系具有与hd 2c突变体相似的表型。在进一步的研究中,P6过表达株系,以及CaMV感染植物,对阿坝和NaCl更敏感,伴随着阿坝/NaCl调节基因的表达增加。此外,组蛋白乙酰化的总体水平在P6过表达系和CaMV感染植物中增加。总的来说,我们的研究结果表明,P6功能障碍组蛋白去乙酰化酶HD 2C的物理相互作用,以促进CaMV感染。
Histone deacetylases (HDACs) are vital epigenetic modifiers not only in regulating plant development but also in abiotic- and biotic-stress responses. Though to date, the functions of HD2C—an HD2-type HDAC—In plant development and abiotic stress have been intensively explored, its function in biotic stress remains unknown. In this study, we have identified HD2C as an interaction partner of the Cauliflower mosaic virus (CaMV) P6 protein. It functions as a positive regulator in defending against CaMV infection. The hd2c mutants show enhanced susceptibility to CaMV infection. In support, the accumulation of viral DNA, viral transcripts, and the deposition of histone acetylation on the viral minichromosomes are increased in hd2c mutants. P6 interferes with the interaction between HD2C and HDA6, and P6 overexpression lines have similar phenotypes with hd2c mutants. In further investigations, P6 overexpression lines, together with CaMV infection plants, are more sensitive to ABA and NaCl with a concomitant increasing expression of ABA/NaCl-regulated genes. Moreover, the global levels of histone acetylation are increased in P6 overexpression lines and CaMV infection plants. Collectively, our results suggest that P6 dysfunctions histone deacetylase HD2C by physical interaction to promote CaMV infection.
