Inflorescences are the main factor affecting fruit yield. The quantity and quality of inflorescences are closely related to fruit quality and yield. The presence of compound inflorescences in cherry tomatoes is well established, and it has been discovered by chance that compound racemes also exist in tomatoes. To explore the formation of compound inflorescences in tomato, transcriptome sequencing was performed on Moneymaker (MM) and Compound Inflorescence (CI) plants. In-florescences were collected in three periods (early, middle and late) in three replicates, for a total of 18 samples. Data analysis showed that the DEGs were most enriched in metabolic pathways and plant hormone signal transduction pathways. The DEGs were also enriched in the cell cycle pathway, photosynthesis pathway, carbon metabolism pathway and circadian rhythm pathway. We found that the (), () and () genes were involved in compound inflorescence development, not only revealing novel genes but also providing a rich theoretical basis for compound inflorescence development.
花序是影响果实产量的主要因素。花序的数量和质量与果实的品质和产量密切相关。樱桃番茄中存在复合花序已得到证实，而番茄中也存在复合总状花序则是偶然发现的。为了探究番茄中复合花序的形成机制，对 Moneymaker（MM）和复合花序（CI）植株进行了转录组测序。在三个时期（早期、中期和晚期）分别收集了三个重复的花序，共采集了 18 个样本。数据分析表明，差异表达基因（DEGs）在代谢途径和植物激素信号转导途径中最富集。DEGs 还在细胞周期途径、光合作用途径、碳代谢途径和昼夜节律途径中富集。我们发现，（）、（）和（）基因参与了复合花序的发育，不仅揭示了新的基因，也为复合花序的发育提供了丰富的理论基础。
