植物对病原体的攻击表现出各种各样的疾病症状。一般来说，大多数植物症状被认为是对宿主植物的有害影响，而对受感染植物的症状的积极方面知之甚少。在此，我们报告了有益的作用，紫顶症状，这是植原体感染植物的特点。首先，通过使用花青素苷生物合成缺陷的植物突变体，我们证明了花青素苷的积累是紫顶症状的直接原因，并且与植原体感染引起的叶细胞死亡的减少有关。此外，我们发现植原体感染导致花青素生物合成途径的显着激活和急剧积累的蔗糖约1000倍，这可以激活花青素生物合成途径。这是第一个研究，以证明紫顶症状的作用和机制，植物植原体相互作用。
Plants exhibit a wide variety of disease symptoms in response to pathogen attack. In general, most plant symptoms are recognized as harmful effects on host plants, and little is known about positive aspects of symptoms for infected plants. Herein, we report the beneficial role of purple top symptoms, which are characteristic of phytoplasma-infected plants. First, by using plant mutants defective in anthocyanin biosynthesis, we demonstrated that anthocyanin accumulation is directly responsible for the purple top symptoms, and is associated with reduction of leaf cell death caused by phytoplasma infection. Furthermore, we revealed that phytoplasma infection led to significant activation of the anthocyanin biosynthetic pathway and dramatic accumulation of sucrose by about 1000-fold, which can activate the anthocyanin biosynthetic pathway. This is the first study to demonstrate the role and mechanism of the purple top symptoms in plant–phytoplasma interactions.
