Filamentous plant pathogens explore host tissues to obtain nutrients for growth and reproduction. Diverse strategies for tissue invasion, defense manipulation, and colonization of inter and intra-cellular spaces have evolved. Most research has focused on effector molecules, which are secreted to manipulate plant immunity and facilitate infection. Effector genes are often found to evolve rapidly in response to the antagonistic host-pathogen co-evolution but other traits are also subject to adaptive evolution during specialization to the anatomy, biochemistry and ecology of different plant hosts. Although not directly related to virulence, these traits are important components of specialization but little is known about them. We present and discuss specific life cycle traits that facilitate exploration of plant tissues and underline the importance of increasing our insight into the biology of plant pathogens.
丝状植物病原体探索宿主组织以获取生长和繁殖所需的营养。已经进化出了多种用于组织入侵、防御操纵以及细胞间和细胞内空间定殖的策略。大多数研究都集中在效应分子上，这些分子被分泌出来以操纵植物免疫并促进感染。人们经常发现效应基因会因宿主与病原体之间的对抗性共同进化而快速进化，但在适应不同植物宿主的解剖学、生物化学和生态学的特化过程中，其他性状也会经历适应性进化。尽管这些性状与毒力没有直接关系，但它们是特化的重要组成部分，然而我们对它们知之甚少。我们展示并讨论了有助于探索植物组织的特定生命周期性状，并强调了深入了解植物病原体生物学的重要性。
