Abstract: To study the floral organ abscission, soybean (Glycine max) inflorescences from four cultivars were used for RNA extraction, RNAseq and transcriptome analysis. A total of 20 GB raw data and 14.87 GB clean data were obtained from RNAseq. The result showed that the transcriptome differences between multiple and relatively less soybean inflorescences mainly lied in substance metabolism, stress response (GLYMA02g03301, GLYMA02G03230, etc.), stimulation response and disease resistance. But genes directly related to abscission show no expression difference. This indicated the possible influences of these genes on soybean flowers and pods abscission. Our research systematically investigated the characteristics and variances of different soybean inflorescences and analyzed the effects of different expression genes on soybean flower abscission and shattering. These data enriched soybean transcriptome database.
