Transcriptomic Analysis of Early Fruit Development in Micro-Tom Tomato Reveals Conserved and Cultivar-Specific Mechanisms.

ABSTRACT: Early fruit development in tomato is driven by complex gene expression patterns and metabolic reprogramming, a crucial phase that shapes the fruit's final size and structure. Previous studies using the Micro-Tom model have largely focused on later stages of development, especially ripening, leaving early developmental processes relatively unexplored. To address this knowledge gap, we performed RNA-seq analyses on Micro-Tom fruits harvested at three key developmental stages: 3, 5, and 8 days post-anthesis (DPA). Pairwise differential gene expression analyses revealed that the most extensive transcriptional reprogramming occurs during the transition from 5 to 8 DPA, while comparatively fewer changes were observed between 3 and 5 DPA. K-means clustering of 11,035 stably expressed genes reveal
