Abstract

In the present study, three matured Japanese plum cultivars with different colored peel and flesh were selected to mine the key transcription factors regulating anthocyanin formation in tissues. Results showed that PsMYB10 was correlated with structural genes C4H, F3H, and ANS. PsMYB6 could positively regulate C4H (r = 0.732) and accumulated anthocyanins in Sanhua plum’s flesh. Sanhua plum has the highest phenolic and anthocyanin contents (10.24 ± 0.37 gallic acid equivalent mg g−1 dry weight (DW) and 68.95 ± 1.03 μg g−1 DW), resulting itself superior biological activity as 367.1 ± 42.9 Trolox equivalent mg g−1 DW in oxygen radical absorbance capacity value and 72.79 ± 4.34 quercetin equivalent mg g−1 DW in cellular antioxidant activity value. The present work provides new insights into the regulatory mechanism of tissue-specific anthocyanin biosynthesis, confirming the pivotal role of anthocyanins in the biological activity of plums, providing essential support for the development of horticultural products enriched with anthocyanins.

日本李果实组织特异性花青素积累的研究——三个品种的比较研究
本研究选择了三个果皮和果肉颜色不同的成熟日本李品种,以挖掘调节组织花青素形成的关键转录因子。结果表明,PsMYB10与结构基因C4H、F3H和ANS相关,PsMYB6对三华李果肉中C4H和花青素的积累具有正调控作用(r=0.732)。三花李的酚类和花青素含量最高(10.24±0.37没食子酸当量mg g−1干重和68.95±1.03,其氧自由基吸收容量值为367.1±42.9 Trolox当量mg g−1 DW,细胞抗氧化活性值为72.79±4.34槲皮素当量mg g–1 DW。本工作为组织特异性花青素生物合成的调控机制提供了新的见解,证实了花青素在李子生物活性中的关键作用,为开发富含花青素的园艺产品提供了必要的支持。
