Analysis of Light-Independent Anthocyanin Accumulation in Mango (<i>Mangifera indica</i> L.)

Light dependent anthocyanin accumulation contributes to the red pigmentation of the fruit skin of mango (<i>Mangifera indica</i> L.). Light-independent pigmentation has also been reported, but remains poorly characterized. In this study, the pigmentation patterns in the skin of two red m...

Light-independent pigmentation has also been reported, but remains poorly characterized. In this study, the pigmentation patterns in the skin of two red mango cultivars, ‘Ruby’ and ‘Sensation’, were evaluated. Metabolomic profiling revealed that quercetin-3-O-glucoside, cyanidin-3-O-galactoside, procyanidin B1, and procyanidin B3 are the predominant flavonoid compounds in the skin of ‘Ruby’ and ‘Sensation’ fruit.

Bagging treatment inhibited the biosynthesis of flovonol and anthocyanin, but promoted the accumulation of proanthocyanidin. Compared with ‘Sensation’, matured ‘Ruby’ fruit skin showed light red pigmentation at 120 days after full bloom (DAFB), showing a light-independent anthocyanin accumulation pattern. However, the increase of anthocyanin concentration, and the expression of key anthocyanin structural and regulatory genes <i>MiUFGT1</i>, <i>MiUFGT3</i>, and <i>MiMYB1</i> in the skin of bagged ‘Ruby’ fruit versus ‘Sensation’ at 120 DAFB was very limited. There was no mutation in the crucial elements of <i>MiMYB1</i> promoter between ‘Ruby’ and ‘Sensation’. We hypothesize that the light-independent anthocyanin accumulation in the skin of mature ‘Ruby’ fruit is regulated by plant hormones, and that ‘Ruby’ can be used for breeding of new more easily pigmented red mango cultivars.Bin ShiHongxia WuBin ZhengMinjie QianAiping GaoKaibing ZhouMDPI AGarticlemangoanthocyaninlight-independentgene expression<i>MiMYB</i> promoterPlant cultureSB1-1110ENHorticulturae, Vol 7, Iss 423, p 423 (2021)
