Anthocyanins and selenium have vital biological functions for human and plants, they were investigated thoroughly and separately in plants. Previous studies indicated pigmented fruits and vegetables had higher selenium concentration, but whether there is a relationship between anthocyanins and selenium is unclear. In this study, a combined phenotypic and genotypic methodological approach was undertaken to explore the potential relationship between anthocyanins and selenium accumulation by using phenotypic investigation and RNA-seq analysis. The results showed that pigmented cultivars enrichment in Se is a general phenomenon observed for these tested species, this due to pigmented cultivars have higher Se efficiency absorption. Se flow direction mainly improve concentration of S-rich proteins of LMW-GS. This may be a result of the MYB and bHLH co-regulate anthocyanins biosynthesis and Se metabolism at the transcriptional level. This thesis addresses a neglected aspect of the relevant relationship between anthocyanins and selenium.
花色苷和硒对人和植物都具有重要的生物学功能，它们在植物中被分别进行了深入的研究。先前的研究表明，色素含量高的水果和蔬菜的硒浓度更高，但花色苷和硒之间是否存在关系尚不清楚。在这项研究中，采用表型研究和 RNA-seq 分析的综合表型和基因型方法，探索花色苷和硒积累之间的潜在关系。结果表明，富含硒的色素品种是这些被测试物种中普遍存在的现象，这是由于色素品种具有更高的硒吸收效率。硒的流动方向主要提高了 LMW-GS 中富含 S 的蛋白质的浓度。这可能是由于 MYB 和 bHLH 在转录水平上共同调节花色苷生物合成和硒代谢。本论文探讨了花色苷和硒之间相关关系的一个被忽视的方面。
