is a smut fungus that infects all aerial maize organs, namely, seedling leaves, tassels, and ears. In all organs, tumors are formed by inducing hypertrophy and hyperplasia in actively dividing cells; however, the vast differences in cell types and developmental stages for different parts of the plant requires that have both general and organ-specific strategies for infecting maize. In this review, we summarize how the maize- interaction can be studied using mutant strains to better understand how individual effectors contribute to this interaction, either through general or specific expression in a cell type, tissue, or organ. We also examine how male sterile maize mutants that do not support tumor formation can be used to explore key features of the maize anthers that are required for successful infection. Finally, we discuss key unanswered questions about the maize- interaction and how new technologies can potentially be used to answer them.
是一种黑粉菌，可感染玉米所有地上器官，即幼苗叶片、雄穗和果穗。在所有器官中，肿瘤是通过诱导活跃分裂细胞的肥大和增生形成的；然而，植物不同部位的细胞类型和发育阶段存在巨大差异，这就要求其在感染玉米时具备通用和器官特异性策略。在本综述中，我们总结了如何利用突变菌株研究玉米与该菌的相互作用，以便更好地了解单个效应子如何通过在细胞类型、组织或器官中的通用或特异性表达对这种相互作用产生影响。我们还研究了不支持肿瘤形成的雄性不育玉米突变体如何用于探索成功感染所需的玉米花药关键特征。最后，我们讨论了关于玉米与该菌相互作用的关键未解决问题，以及新技术如何有可能用于解答这些问题。
