Special Issue Information

Dear Colleagues,

Pollination in horticultural plants is crucial for reproduction, enabling fertilization and the production of seeds; it ensures genetic diversity and plant survival. Fruit development following successful pollination leads to the formation of edible structures, vital for seed dispersal and ecosystem balance. The study of pollination mechanisms and fruit development in horticultural crops is rooted in understanding plant reproduction and agricultural productivity. This Special Issue, "Advances in Genetics of Pollination Mechanism and Fruit Development of Horticultural Crops", aims to explore the genetic underpinnings of these processes, highlighting cutting-edge research that bridges traditional breeding with modern genomic tools. We seek to compile innovative studies that elucidate the molecular and genetic pathways governing pollination efficiency, female and male gametophyte development, flower organogenesis, fruit formation, and fruit maturation. We invite submissions that employ advanced techniques such as CRISPR/Cas9, transcriptomics, and genome-wide association studies (GWASs) to uncover novel genes and regulatory networks. By fostering interdisciplinary collaboration, this Special Issue aims to advance our knowledge and contribute to the sustainable improvement of horticultural crops.

The WUSCHEL-related homeobox (WOX) transcription factors (TF) regulate critical developmental processes in plants, including organ formation and stem cell maintenance. Although characterized in model species, the WOX family remains unexplored in passion fruit (Passiflora edulis). In this study, 10 WOX genes were identified in passion fruit, which are distributed across six chromosomes. We analyzed the phylogenetic relationships, gene structure, conserved motifs, and syntenic relationships of the PeWOX genes. Multiple sequence alignment analysis revealed strong conservation of the homeodomain region among WOX TF family members. Phylogenetic reconstruction further demonstrated that the 10 identified PeWOX genes in passion fruit could be classified into three distinct evolutionary clades: the WUS clade, the Intermediate clade, and the Ancient clade. The conserved motif and gene structure of WOX TF family members in the same evolutionary clade were highly consistent. Expression analysis based on RNA-seq and RT-qPCR showed that most PeWOX genes were expressed during ovule development. The expression level of PeWOX genes varies with different stress conditions. Subcellular localization analysis of tobacco leaf epidermal cells showed that PeWOX3/7/10 proteins were localized in the nucleus and cell membrane. Collectively, this study lays a foundation for future functional studies of passion fruit WOX genes. Full article
