Expression profiles of soybean SWEET genes in different tissues. a Hierarchical cluster of expression profiles from two RNA-seq datasets in 24 tissues covering the whole life cycle of soybean (Williams 82). Sources of the samples are as follows: Dataset 1 - YL (young leaves), FL (flower), PD.1 cm (one cm pod), PS.10d (pod shell 10 Days After Flowering (DAF)), PS.14d (pod shell 14DAF), S.10d (seed 10DAF), S.14d (seed 14 DAF), S.21d (seed 21DAF), S.25d (seed 25DAF), S.28d (seed 28DAF), S.35d (seed 35DAF), S.42d (seed 42DAF), R1 (root), and Nod (nodule); Dataset 2 - GSS (globular stage whole seed), HRT (heart stage), COT (cotyledonary stage), EM (early maturation), DWS (dry whole seed), LF (leaf), R2 (root), STM (stem), FB (floral bud), and SDL (seedling). b Expression pattern of 52 GmSWEET genes. Bars show the expression of all genes in different developmental stages from both datasets. For simplicity, the datasets were marked with vegetative and reproductive stages. c qRT-PCR analysis of 21 selected GmSWEET genes in pedicel, pod, and seed tissues
