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 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.

The Spodoptera genus is defined as the pest-rich genus because it contains some of the most destructive lepidopteran crop pests, characterized by a wide host range. During feeding, the caterpillars release small amounts of oral secretion (OS) onto the wounded leaves. This secretion contains herbivore-induced molecular patterns (HAMPs) that activate the plant defense response, as well as effectors that may inhibit or diminish the plant's anti-herbivory response.

Plants emit green leaf volatiles (GLVs) in response to biotic and abiotic stress. Receiver plants perceive GLVs as alarm cues resulting in activation of defensive or protective mechanisms. While this is well documented, it is not known how GLVs are perceived by receiver cells and what the structural determinants are for GLV activity.

toxins (ATs) are a group of toxins produced by fungi that frequently contaminate tomatoes and tomato products. Recently, the European Food Safety Authority evaluated ATs for their genotoxic and carcinogenic properties. infestation is often controlled using ad hoc treatment strategies (fungicides).

Understanding the ammonium (NH) uptake and transport systems, particularly genes, is important for plant growth and defense. However, there is a lack of research on identifying and analyzing genes in pomegranate, emphasizing the need for further investigation in this area. Five genes ( to ) were identified, all of which contain the PF00909 domain, a feature of ammonium transporters.

Fruit firmness is crucial for storability, making cultivating varieties with higher firmness a key target in tomato breeding. In recent years, tomato varieties primarily rely on hybridizing ripening mutants to produce F hybrids to enhance firmness. However, the undesirable traits introduced by these mutants often lead to a decline in the quality of the varieties.
