2.A.123.1.26
Sweet13 (Sweet12) of 294 aas and 7 TMSs. Both Sweet13 and 14 transport the plant hormone, gibberellin (GA). A double mutant has a defect in anther dehiscence. This mutant also exhibits altered long distant transport of exogenously
applied GA and altered responses to GA during germination and seedling
stages (Kanno et al. 2016). In dragon fruit (pitaya; H. undatus) Sweets function in phloem loading, seed filling, nectar secretion, and fruit sweetness development (Jiang et al. 2023). Novel transport-enhancing mutations have been isolated (Narayanan et al. 2024).
