Summary: Bacteria release volatile organic compounds (VOCs) into the environment, which have various effects on plants, including promoting growth, suppressing pathogens, and acting as signaling molecules. Some VOCs also exhibit antimicrobial and pesticidal activities. Different bacterial species produce different VOCs, with some contributing to plant growth promotion. Understanding the mechanisms by which VOCs affect plant genes and metabolic pathways is still a topic of ongoing research.

Summary: In order to study the changes in proteins and metabolites under stress conditions, genomics, proteomics, and metabolomics methods have been employed. Extensive research in the past decade has gradually revealed the underlying processes by which plants respond to environmental stress. Abiotic stresses such as extreme temperatures, water scarcity, and metal toxicity resulting from human activity and urbanization are of major concern due to their potential for unsustainable warming trends and significant reduction in crop yield. Stress triggers various physiological changes in plants, including the production of reactive oxygen species, stomatal regulation, cytosolic calcium ion concentrations, alteration of metabolite profiles, expression of stress-responsive genes, and activation of potassium channels. However, research on abiotic stresses is limited as the complex defense mechanisms involving multiple genes and pathways remain unexplored. Thus, an integrative approach that considers genomic sequences, transcripts, protein organization and interactions, stress-specific transcriptome collections, and mutant screens is crucial in understanding plant responses to abiotic stress. In this review, we focus on the genomics, proteomics, and metabolomics of tomatoes under abiotic stress.

Summary: This study investigated changes in wheat resistance to wheat streak mosaic virus (WSMV) at normal and elevated temperatures and their effects on the emission of volatile organic compounds (VOCs) in wheat cultivars. The results showed that VOCs in the leaves of resistant (R) and susceptible (S) cultivars responded differently to WSMV and temperature changes. Several metabolic pathways and compounds were up-regulated in R plants, especially at an earlier time and at elevated temperatures. The lipoxygenase pathway played an important role in increasing vector attractiveness and tolerance to biotic and abiotic stresses. The results emphasize the importance of understanding the synchronized regulation of defense-related VOCs for plant resistance to viruses and heat stress.

Summary: The study shows that Bacillus amyloliquefaciens SN16-1 can assist tomato in resisting Rhizoctonia solani infection by activating the plant's defense mechanisms. SN16-1 activates the tomato's defenses through systemic-acquired resistance, rather than the classic induction of systemic resistance. The response of tomatoes to SN16-1 and R. solani RS520 also differs significantly.

Summary: The study revealed that the quality of tomato fruit in the red-fruited tomato clade is influenced by multiple genes controlling the balance of sugars, acids, and volatile compounds in the fruit. These genes exhibit high genetic diversity at specific loci, with novel haplotypes that could be used in breeding programs to enhance modern tomato quality. Additionally, gene expression patterns varied among phylogenetically diverse tomato accessions, with no clear relationship between expression and metabolite levels.

Summary: A study on European traditional tomato varieties found that high phenotypic diversity was created by traditional farmer-driven selection, inadvertently combining a few polymorphic loci. Analysis of 1254 tomato accessions revealed a continuous genetic gradient between traditional and modern varieties, with low genetic diversity and distinct genetic groups among traditional European tomatoes. Spanish and Italian varieties showed higher genetic diversity, possibly indicating independent secondary centers of diversity, while other varieties may be the result of recent migrations and hybridizations among European regions. A few highly polymorphic loci were associated with fruit morphological traits in the European traditional collection, suggesting a history of balancing selection by tomato farmers to maintain morphological variation.

Summary: Gene editing is a valuable tool for crop breeding, but its impact on agriculture depends on the regulation of crops generated by gene editing technologies and our understanding of the mutations' impact on plant phenotype. This study focuses on evaluating the effects of induced mutations in a locus-specific manner for plant breeding. By targeting the GF locus in tomatoes, the researchers assessed the efficiency, specificity, and mutation patterns associated with CRISPR/Cas9 activity for this gene. The results showed that CRISPR/Cas9-mediated mutation of the GF locus in tomatoes is efficient, specific, and reproducible, and it offers potential improvements for cultivation, consumer appreciation, and health.
