Special Issue Information

Dear Colleagues,

Global climate change has been a growing concern, and its impact on crop yield and quality is far from being well understood. It is of great significance to identify stress-tolerant germplasm and explore tolerance genes. A variety of omics approaches have been widely used to study the responses of crops to various stresses and the molecular mechanisms of resilience. The rapid development of transgenic and genome-editing technology provides a powerful tool for the identification of stress-tolerant genes and the analysis of molecular mechanisms. Research advances in this field would lead to crop genetic improvement to meet the challenges of global climate change. As a globally important vegetable and a research model for plant biology, tomato is moderately sensitive to various stresses. Important research topics regarding tomato stress tolerance include but are not limited to germplasm identification, QTL analysis, gene discovery, responsive network analysis, molecular mechanism elucidation and genetic engineering. This Special Issue is devoted to demonstrating the important progress of tomato tolerance research.

The 14-3-3 proteins, which are ubiquitous and highly conserved in eukaryotic cells, play an essential role in various areas of plant growth, development, and physiological processes. The tomato is one of the most valuable vegetable crops on the planet. The main objective of the present study was to perform genome-wide identification and analysis of the tomato 14-3-3 (SlTFT) family to investigate its response to different abiotic stresses and phytohormone treatments in order to provide valuable information for variety improvement. Here, 13 SlTFTs were identified using bioinformatics methods. Characterization showed that they were categorized into ε and non-ε groups with five and eight members, accounting for 38.5% and 61.5%, respectively. All the SlTFTs were hydrophilic, and most of them did not contain transmembrane structural domains. Meanwhile, the phylogeny of the SlTFTs had a strong correlation with the gene structure, conserved domains, and motifs. The SlTFTs showed non-random chromosomal distribution, and the promoter region contained more cis-acting elements related to abiotic stress tolerance and phytohormone responses. The results of the evolutionary analysis showed that the SlTFTs underwent negative purifying selection during evolution. Transcriptional profiling and gene expression pattern analysis showed that the expression levels of the SlTFTs varied considerably in different tissues and periods, and they played a specific role under various abiotic stresses and phytohormone treatments. Meanwhile, the constructed protein-based interaction network systematically broadens our understanding of SlTFTs. Finally, the virus-induced gene silencing of SlTFT4 affected the antioxidant and reactive oxygen species defense systems, increased the degree of cellular damage, and reduced salt resistance in tomatoes.
