Special Issue Information

Dear Colleagues,

Vegetable crops encompass numerous species that are major nutrient sources for humans, but their growth and development are constantly exposed to various abiotic and biotic stresses, such as drought, salinity, extreme temperature, nutrient deficiency, insects, and pathogens. To deal with those stresses, vegetable crops employ complex signaling cascades consisting of a number of stress-related genes and proteins, thus enabling rapid reactions to stress and facilitating adaptive growth and development. In addition, genomic research tools and sequencing technologies are widely used for exploring the genetic basis and molecular mechanisms underlying different developmental processes in vegetable crops, which will be of great significance for improving their yield and quality in the future.

The aim of this Special Issue on “Advancements in Genetic Improvement of Stress Tolerance in Vegetable Crops” is to present innovative studies on the development of new genomic and molecular techniques to improve the quality and resistance to biotic and abiotic stresses of vegetable crops, and studies on the identification of new genes or specific alleles through multi-omics technologies and genomic research. This Special Issue also encourages articles describing in depth innovative molecular genetics research on agriculturally useful genes for the genetic improvement of vegetable crops.

We look forward to your excellent contributions to this Special Issue of Horticulturae.

Shi-related sequence (SRS) proteins, which consist of the RING-like zinc finger domain and IGGH domain, are plant-specific transcription factors that have been well-studied in several plant species. However, information about SRS genes and their roles in cucumber (Cucumis sativus L.) is limited. Therefore, we performed detailed bioinformatic analysis of the SRS gene family, including gene numbers and positions, genes structures, conserved motif distribution patterns, phylogenetic analysis, and promoter cis-element analysis. Eight SRS genes were identified in cucumber and distributed on all seven cucumber chromosomes. SRS genes are conserved in plants and divided into two groups in cucumber based on their protein sequence. In silico analysis predicted that most genes may function in response to abiotic stresses and phytohormones. Gene ontology analysis predicted the possible involvement of genes in development and reproduction, and DNA and protein binding on a molecular level. Furthermore, the differential expression pattern of SRS genes in leaf, stem and root under the condition of Zn2+ stress suggested their roles in response to Zn2+ stress. Furthermore, our metal tolerance assay suggested that CsSRS2 and CsSRS5 mediated enhanced tolerance to Zn2+ stress in Escherichia coli cells. Our study provides a foundation for the functional study of SRS genes in cucumber. Full article

GOLDEN2-like (GLK) transcription factor genes are involved in chloroplast biogenesis during all stages of plant growth and development, as well as in the response to biotic and abiotic stresses. However, little is known about this transcription factor family in eggplant. In this study, we identified 54 GLK genes in the eggplant genome (S. melongena L.) and classified them into seven groups (G1–G7). Structural analysis illustrated that the SmGLK proteins of specific groups are relatively conserved. Cis-acting elements indicated that these genes are likely to be involved in multiple responses stimulated by light, phytohormones, and abiotic stress. Collinear analysis indicated that expansion of the SmGLK gene family primarily occurred through segmental duplication. Tissue-specific expression analysis revealed that SmGLKs were preferentially expressed in leaves, fruits, and seeds. Further screening of SmGLK genes revealed their differential expression under various treatments. Notably, SmGLK18 was significantly responsive to multiple phytohormones and stress treatments, whereas SmGLK3 and SmGLK12 were highly induced by ABA, IAA, SA, and drought treatments. Our study provides new information on the eggplant GLK family systematically and comprehensively. For the first time, we propose that SmGLK18 may play a key role in improving heat resistance. This study provides valuable candidate gene resources for further functional research and will benefit eggplant molecular breeding. Full article
