Special Issue Information

Dear Colleagues,

In recent years, significant advancements have been achieved in vegetable breeding and molecular research. Researchers have employed gene editing, molecular marker-assisted breeding, and other cutting-edge technologies to enhance disease resistance, tolerance, yield, and quality in vegetable crops. Furthermore, the rapid advancement of genomics, transcriptomics, proteomics, and other high-throughput sequencing technologies has provided deeper insights into the genetic foundations of crucial vegetable traits. These developments not only facilitate the understanding of the genetic mechanisms underlying complex traits such as growth and development, quality formation, and stress resistance, but also offer enriched genetic resources and a theoretical framework for precision breeding.

This Special Issue “Advances in Vegetable Breeding and Molecular Research” aims to advance vegetable research by presenting original research articles and reviews focused on vegetable breeding and molecular research. Topics of interest include, but are not limited to, the latest findings on vegetable variety improvement through gene editing technology, the application of molecular marker-assisted selection to expedite the breeding process, and recent progress in the genomics, transcriptomics, and epigenetics of vegetable crops, as well as practical explorations of improving vegetable stress tolerance through molecular means. We are looking forward to seeing manuscripts with innovative, cutting-edge, and practical values, which will jointly promote the rapid development of vegetable breeding and molecular biology.

Wolfberry (Lycium barbarum L.) is a valued traditional medicinal plant and dietary supplement in China. The basic leucine zipper (bZIP) transcription factor (TF) family is a multifunctional group of regulatory proteins critical to plant biology, orchestrating processes such as growth and development, secondary metabolite biosynthesis, and stress responses to abiotic conditions. Despite its significance, limited information about this gene family in wolfberry is available. In this study, a total of 66 LbabZIP genes were identified, exhibiting a non-uniform distribution across all 12 chromosomes. Phylogenetic analysis divided these genes into 13 subgroups based on comparison with Arabidopsis bZIP proteins. Analysis of gene structures and conserved motifs revealed high similarities within individual subgroups. Gene duplication analysis indicated that dispersed duplication (DSD) and whole-genome duplication (WGD) events were the primary drivers of LbabZIP gene family expansion, with all duplicated genes subject to purifying selection. Cis-regulatory element (CRE) analysis of LbabZIP promoter regions identified numerous elements associated with plant growth and development, hormone signaling, and abiotic stress responses. Gene Ontology (GO) annotation further indicated that the LbabZIP genes are involved in transcriptional regulation, metabolism, and other biological processes. Transcriptome data and quantitative real-time PCR (qRT-PCR) analysis demonstrated tissue-specific expression patterns for several LbabZIP genes. Notably, LbaZIP21/40/49/65 showed significant involvement in wolfberry fruit development. Subcellular localization assays confirmed that these four proteins are nucleus-localized. This comprehensive analysis provides a theoretical foundation for future studies investigating the biological functions of LbabZIP genes, especially their role in wolfberry fruit development.

The Solanaceae family, which includes key crops such as tomato, pepper, eggplant, wolfberry, and groundcherry, is distinguished by its diversity of fruit types. However, the conservation of gene expression regulatory networks across different species remains poorly understood. This study utilizes comparative transcriptomics to analyze 293 transcriptome samples from 22 Solanaceae species, focusing on the expression profiles of reproductive organ (flower and fruit)-specific genes. Our results reveal evolutionary conservation in the expression patterns of these genes, particularly within regulatory pathways essential for plant reproduction. A detailed comparative analysis of gene expression patterns between tomato and pepper reveals common regulatory networks governing fruit development. Furthermore, through co-expression network analysis, we identified functional partners of YABBY in flower/fruit development and found that YABBY genes coordinate fruit development through spatiotemporal dynamic expression, shaping its regulatory role. These findings provide valuable insights that can guide future research on fruit development genes in Solanaceae species. Full article
