The Ve-resistance locus in tomato and potato affects both stress/defense and growth, consistent with a signaling intercept and a competitive regulatory mechanism. Acting in an antagonistic fashion, the two genes comprising the tomato Ve-resistance locus have been shown to influence both the defense/stress cascade, which causes wilt symptoms, and plant growth (Nazar et al. in Planta 247:1339–1350, 2018c); in contrast, both have been reported to elevate wilt resistance in potato or Arabidopsis. In a further examination of this influence in potato transformed with the Ve1 gene, effects are again demonstrated with respect to both disease resistance and crop productivity consistent with the Ve locus being a signaling intercept and the antagonistic effects, previously observed in tomato. The results support a competitive model in which the tomato Ve1 and Ve2 proteins act to reduce the detrimental effects of the defense/stress cascade and energy transfers to the developing potato tubers.

Ve-resistance 基因座，植物信号拦截

番茄和马铃薯中的 Ve 抗性基因座影响胁迫/防御和生长，与信号拦截和竞争性调节机制一致。以拮抗方式发挥作用，组成番茄 Ve 抗性基因座的两个基因已显示影响防御/应激级联反应，导致萎蔫症状和植物生长（Nazar et al. in Planta 247:1339–1350, 2018c ); 相比之下，据报道两者都提高了马铃薯或拟南芥的枯萎病抗性。在进一步检查用 Ve1 基因转化的马铃薯中的这种影响时，再次证明了对抗病性和作物生产力的影响，这与先前在番茄中观察到的 Ve 基因座是信号拦截和拮抗作用一致。
