摘要： 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.
