Common bean (Phaseolus vulgaris L.) is a short-day plant and its flowering time, and consequently, pod yield and quality is influenced by photoperiod. In this study, the photoperiodic-sensitive variety ‘Hong jin gou’, which flowers 31 days (d) earlier in short-day than in long-day, was used as the experimental material. Samples were collected to determine the growth and photosynthetic parameters in each daylength treatment, and transcriptome and metabolome data were conducted. We identified eight genes related to flowering by further screening for differentially expressed genes. These genes function to regulate the biological clock. The combination of differentially expressed genes and metabolites, together with the known regulation network of flowering time and the day–night expression pattern of related genes allow us to speculate on the regulation of flowering time in the common bean and conclude that TIMING OF CAB EXPRESSION1 (TOC1) plays a pivotal role in the network and its upregulation or downregulation causes corresponding changes in the expression of downstream genes. The regulatory network is also influenced by gibberellic acid (GA) and jasmonic acid (JA). These regulatory pathways jointly comprise the flowering regulatory network in common bean.

普通豆（菜豆）L.）是一棵短时植物，其开花时间短，因此，荚果的产量和品质受光周期的影响。在这项研究中，对光周期敏感的品种“红金沟”作为实验材料，在短日比早日提前31天（d）开花。收集样品以确定每天进行的处理中的生长和光合参数，并进行转录组和代谢组数据。通过进一步筛选差异表达基因，我们鉴定了与开花有关的八个基因。这些基因起到调节生物钟的作用。差异表达的基因和代谢产物的组合，CAB EXPRESSION1（TOC1）的时序在网络中起着关键作用，其上调或下调会导致下游基因表达的相应变化。监管网络还受到赤霉素（GA）和茉莉酸（JA）的影响。这些调控途径共同构成了普通豆的开花调控网络。
