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最终形成了复杂的模式，其中病原体可以具有狭窄或广泛的宿主范围。这种宿主专业化的进化范式也适用于器官特异性感染过程。然而，为什么一些病原体更喜欢特定的器官，而另一些病原体却能够感染整个植物，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，但对涉及器官特异性的病原体分子决定因素知之甚少。
