Transcriptome Analysis of the Development of Pedicel Abscission Zone in Tomato

Plant organ abscission is a common phenomenon that occurs at specific position called the zone (AZ). The differentiation and development of pedicel AZ play important roles in flower fruit abscission, which are great significance for tomatoes before harvest. Previous studies have reported some genes involved differentiation; however, regulating cell after remain poorly understood. In this study, transcriptome analyses tomato samples were performed 0, 5, 15, 30 days post-anthesis (DPA). Pedicel growth was mainly observed 15 DPA. A principal component analysis correlation carried out order to compare repeatability reliability different samples. We 38 up-regulated 31 down-regulated significantly altered during 0 5 DPA, may key enlargement. GO KEGG enrichment selected DEGs under all three comparisons conducted. Auxin-signaling-related analyzed, as well AUX/IAA, GH3, small auxin RNA (SAUR) gene expression patterns. presented results provide information on development, might help or production facilities.
