Plant antifungal proteins include the pathogenesis-related (PR)-5 family of fungi- and other stress-responsive thaumatin-like proteins (TLPs). However, the information on the TLPs of garlic ( L.), which is often infected with soil fungi, is very limited. In the present study, we identified 32 homologs in the cv. Ershuizao genome, which may function in the defense against attack. The promoters of () genes contained -acting elements associated with hormone signaling and response to various types of stress, including those caused by fungal pathogens and their elicitors. The expression of genes in -resistant and -susceptible garlic cultivars was differently regulated by infection. Thus, in the roots the mRNA levels of and genes were increased in resistant and decreased in susceptible cultivars, suggesting the involvement of these genes in the garlic response to . attack. Our results provide insights into the role of TLPs in garlic and may be useful for breeding programs to increase the resistance of crops to infections.
植物抗真菌蛋白包括病程相关（PR）-5家族的真菌及其他应激反应类甜蛋白（TLP）。然而，关于常受土壤真菌侵染的大蒜（ ）TLP的信息非常有限。在本研究中，我们在二水早基因组中鉴定出32个同源物，它们可能在抵御 攻击中发挥作用。（ ）基因的启动子包含与激素信号传导以及对各种类型应激（包括由真菌病原体及其激发子引起的应激）反应相关的顺式作用元件。 基因在抗 和感 大蒜品种中的表达受 感染的调控方式不同。因此，在根部，抗 品种中 和 基因的mRNA水平升高，而感 品种中则降低，这表明这些基因参与了大蒜对 攻击的反应。我们的结果为TLP在大蒜中的作用提供了见解，可能有助于育种计划提高作物对 感染的抗性。
