Coevolution between plants and pathogens has culminated in intricate patterns where pathogens can have a narrow or wide host range. This evolutionary paradigm of host specialization also holds true for organ-specific infection processes. However, it remains elusive why some pathogens prefer a given organ, whereas others are able to infect the entire plant. Studies have shown that distinct plant organs may utilize distinct defense mechanisms, but not much is known about pathogens' molecular determinants involved in organ-specificity.

植物和病原体之间的共同进化以错综复杂的模式达到顶峰，其中病原体可以有窄的或宽的寄主范围。这种宿主专门化的进化范式也适用于特定器官的感染过程。然而，为什么一些病原体偏爱特定的器官，而另一些病原体能够感染整个植物，这一点仍然难以捉摸。研究表明，不同的植物器官可能利用不同的防御机制，但对病原体参与器官特异性的分子决定因素知之甚少。
