Understanding the intricate interplay between plants and bacteria is paramount for elucidating mechanisms of immunity and disease. This review synthesizes current knowledge on the role of flagella in bacterial motility and host recognition, shedding light on the molecular mechanisms underlying plant immunity and bacterial pathogenicity. We delve into the sophisticated signaling network of plants, highlighting the pivotal role of pattern recognition receptors (PRRs) in detecting conserved molecular patterns known as microbe-associated molecular patterns (MAMPs), with a particular focus on flagellin as a key MAMP. Additionally, we explore recent discoveries of solanaceous-specific receptors, such as FLAGELLIN SENSING 3 (FLS3), and their implications for plant defense responses. Furthermore, we examine the role of bacterial motility in host colonization and infection, emphasizing the multifaceted relationship between flagella-mediated chemotaxis and bacterial virulence. Through a comprehensive analysis of flagellin polymorphisms within the genus Xanthomonas, we elucidate their potential impact on host recognition and bacterial pathogenicity, offering insights into strategies for developing disease-resistant crops. This review is intended for professionals within the fields of crops sciences and microbiology.
理解植物和细菌之间复杂的相互作用对于阐明免疫和疾病机制至关重要。这篇综述综合了目前关于鞭毛在细菌运动和宿主识别中的作用的知识，揭示了植物免疫和细菌致病性的分子机制。我们深入探讨了植物复杂的信号网络，强调了模式识别受体（PRRs）在检测称为微生物相关分子模式（MAMPs）的保守分子模式方面的关键作用，特别关注鞭毛作为关键 MAMP 的作用。此外，我们还探讨了茄科特异性受体（如 FLS3）的最新发现及其对植物防御反应的影响。此外，我们研究了细菌运动在宿主定殖和感染中的作用，强调了鞭毛介导的趋化性与细菌毒力之间的多方面关系。通过对黄单胞菌属内鞭毛蛋白多态性的综合分析，我们阐明了它们对宿主识别和细菌致病性的潜在影响，为开发抗病作物提供了思路。本综述面向作物科学和微生物学领域的专业人士。
