Diseases caused by Xylella fastidiosa have attained great importance worldwide as the pathogen and its insect vectors have been disseminated. Since this is the first plant pathogenic bacterium for which a complete genome sequence was determined, much progress has been made in understanding the process by which it spreads within the xylem vessels of susceptible plants as well as the traits that contribute to its acquisition and transmission by sharpshooter vectors. Although this pathogen shares many similarities with Xanthomonas species, such as its use of a small fatty acid signal molecule to coordinate virulence gene expression, the traits that it utilizes to cause disease and the manner in which they are regulated differ substantially from those of related plant pathogens. Its complex lifestyle as both a plant and insect colonist involves traits that are in conflict with these stages, thus apparently necessitating the use of a gene regulatory scheme that allows cells expressing different traits to co-occur in the plant.

生活在两个世界中：Xylella fastidiosa的植物和昆虫生活方式。

由于病原菌及其昆虫载体已经传播，由小木杆菌引起的疾病在世界范围内已变得非常重要。由于这是第一个确定完整基因组序列的植物致病细菌，因此在了解其在易感植物的木质部血管中扩散的过程以及有助于其获取和传播的性状方面已经取得了很大进展。神枪手矢量。尽管该病原体与黄单胞菌属有许多相似之处，例如使用小脂肪酸信号分子来协调毒力基因的表达，但其用于引起疾病的性状及其调控方式与相关植物大不相同。病原体。
