在过去的40年里，主要是叶片叶肉细胞感染病原体和咀嚼昆虫的深入分子研究，导致引人注目的植物病原体和植物昆虫相互作用的模型。然而，一些最具破坏性的病原体和昆虫害虫生活在韧皮部中或以其为食，韧皮部是属于植物维管系统的系统性组织。韧皮部组织很难研究，并且韧皮部栖息的病原体通常不可能培养，从而限制了我们在分子水平上对韧皮部-昆虫/病原体相互作用的理解。在这个角度来看，我们强调最近的文献报道，在了解韧皮部与昆虫和原核病原体的相互作用的重大进展，并试图确定关键问题，需要注意的未来研究。很明显，韧皮部-昆虫/病原体相互作用的研究代表了植物科学的一个令人兴奋的前沿，新的科学专业知识和资金的涌入对于在这一重要研究领域取得更快进展至关重要，这是全球粮食安全不可或缺的。
For the past 4 decades, intensive molecular studies of mostly leaf mesophyll cell-infecting pathogens and chewing insects have led to compelling models of plant-pathogen and plant-insect interactions. Yet, some of the most devastating pathogens and insect pests live in or feed on the phloem, a systemic tissue belonging to the plant vascular system. Phloem tissues are difficult to study, and phloem-inhabiting pathogens are often impossible to culture, thus limiting our understanding of phloem-insect/pathogen interactions at a molecular level. In this Perspective, we highlight recent literature that reports significant advances in the understanding of phloem interactions with insects and prokaryotic pathogens and attempt to identify critical questions that need attention for future research. It is clear that study of phloem-insect/pathogen interactions represents an exciting frontier of plant science, and influx of new scientific expertise and funding is crucial to achieve faster progress in this important area of research that is integral to global food security.
