Different flowering phenotypes and number of differentially expressed genes during floral induction in ‘SJ’ and ‘SX’ longan. a Different flowering traits of ‘SJ’ and ‘SX’. ‘SJ’ longan blossoms continuously; both terminal and axillary shoots can differentiate into inflorescences, and flowers and fruits can be observed at the same time on one tree. T1 represents the dormant stage (before the emergence of floral primordia), T2 represents the emergence of floral primordium stage, and T3 represents the floral organ formation stage. The red arrows represent comparisons conducted in quantitative analyses. The numbers by the arrows denote the number differentially expressed genes for the specified comparison. b Venn diagram showing the number of DEGs between ‘SJ’ and ‘SX’ longan during the floral induction process. c Venn diagram showing the number of DEGs during floral induction in ‘SJ’. d Venn diagram showing the number of DEGs during floral induction in ‘SX’
