Tomato yellow leaf curl disease (TYLCD) and salinity stress adversely affect tomato production worldwide by causing extensive damages. In Tunisia, identifying TYLCD resistant cultivars selected in different environments is useful to devise counter-measures. To this end, 20 tomato commercial cultivars were screened for different Ty gene alleles’ combinations and evaluated either for TYLCD incidence or salinity constraint. We built a biological multi-layer network for integrating, visualizing and modelling generated data. It is a simple representation view linking allelic combinations to tomato cultivars behaviour under viral and salt stresses. In addition, we analyzed differential expression of transcriptions factors (TFs) belonging to WRKY and ERF families in selected resistant (R) and susceptible (S) tomato cultivars. Gene expression was evaluated for short- and long stress exposure to either TYLCSV infection or to both viral and salinity stresses. Evidence is that TFs promote resistance to abiotic and biotic stresses through a complex regulatory network.

在盐度和病毒胁迫联合作用下番茄不同基因型的反应。

番茄黄叶卷曲病（TYLCD）和盐分胁迫通过造成广泛的损害，对全世界的番茄生产产生不利影响。在突尼斯，确定在不同环境中选择的耐TYLCD的品种有助于制定对策。为此，筛选了20个番茄商业品种以寻找不同的Ty基因等位基因组合，并评估TYLCD的发生率或盐度限制。我们构建了一个生物多层网络，用于集成，可视化和建模生成的数据。这是一个简单的表示视图，将等位基因组合与病毒和盐胁迫下番茄品种的行为联系起来。此外，我们分析了在选定的抗性（R）和易感性（S）番茄品种中属于WRKY和ERF家族的转录因子（TFs）的差异表达。评估了基因表达的长期和短期暴露于TYLCSV感染或病毒和盐分胁迫。有证据表明，TFs通过复杂的调控网络促进了对非生物和生物胁迫的抗性。
