International Journal of Horticulture, 2025, Vol.15, No.1, 8-20 http://hortherbpublisher.com/index.php/ijh 13 Figure 2 Expression patterns of HuSWEETs in pitaya pulps. (A) Expression analyses of 19 HuSWEET genes in pitaya pulps during fruit development. (B) RT-qPCR analyses of 19 HuSWEETs in mature fruits of pitaya. The data were shown as the means ± SDs of three independently biological replicates. The different letters above bars indicate significant differences at the p < 0.05 level according to Duncan’s multiple comparison tests (Adopted from Jiang et al., 2019) Image caption: The figure shows that most HuSWEET genes exhibit a downward expression trend during fruit development, especially HuSWEET7a, HuSWEET7b, and HuSWEET12b, while the expression of HuSWEET12a, HuSWEET12d, and HuSWEET13d increases significantly as the fruit matures, reaching the highest levels in 35-day mature fruits. Combined with sugar accumulation data, the significant positive correlation between the expression of HuSWEET12a and HuSWEET13d and sugar content suggests that these genes may play critical roles in sugar transport and accumulation (Adapted from Jiang et al., 2019)
