Abstract

BACKGROUND

Sucrose transporters (SUTs) mediate sucrose phloem loading in source tissue and sucrose unloading into sink tissue in potatoes and higher plants, thus playing a crucial role in plant growth and development. In potatoes, the physiological function of the sucrose transporters StSUT1 and StSUT4 has been clarified, whereas the physiological role of StSUT2 is not yet fully understood.

METHODS AND RESULTS

This study analyzed the relative expression of StSUT2 compared to that of StSUT1 and StSUT4 in different tissues from potatoes and its impact on different physiological characteristics by using StSUT2-RNA interference lines. Here, we report a negative effect of StSUT2-RNA interference on plant height, fresh weight, internodes number, leaf area, flowering time, and tuber yield. However, our data indicate that StSUT2 is not involved in carbohydrate accumulation in potato leaves and tubers. In addition, the data of the RNA-seq between the StSUT2-RNA interference line and WT showed that 152 genes were differentially expressed, of which 128 genes were upregulated and 24 genes were downregulated, and the GO and KEGG analyses revealed that differentially expressed genes were mainly related to cell wall composition metabolism.

CONCLUSIONS

Thus, StSUT2 functions in potato plant growth, flowering time, and tuber yield without affecting carbohydrate accumulation in the leaves and tubers but may be involved in cell wall composition metabolism.

摘要

背景

蔗糖转运蛋白（SUTs）介导马铃薯及高等植物中源组织的蔗糖韧皮部装载和蔗糖卸载到库组织中，因此在植物生长发育中起关键作用。在马铃薯中，蔗糖转运蛋白StSUT1和StSUT4的生理功能已得到阐明，而StSUT2的生理作用尚未完全了解。

方法与结果

本研究通过使用StSUT2-RNA干扰系，分析了马铃薯不同组织中StSUT2相对于StSUT1和StSUT4的相对表达及其对不同生理特性的影响。在此，我们报道了StSUT2-RNA干扰对株高、鲜重、节数、叶面积、开花时间和块茎产量的负面影响。然而，我们的数据表明StSUT2不参与马铃薯叶片和块茎中的碳水化合物积累。此外，StSUT2-RNA干扰系与野生型之间的RNA-seq数据显示，有152个基因差异表达，其中128个基因上调，24个基因下调，GO和KEGG分析表明差异表达基因主要与细胞壁组成代谢有关。

结论

因此，StSUT2在马铃薯植株生长、开花时间和块茎产量方面发挥作用，而不影响叶片和块茎中的碳水化合物积累，但可能参与细胞壁组成代谢。
