“…The anthocyanin synthesis in plants could also be regulated by visible light or be light independent. For instance, the roots of some potatoes (Liu et al, 2016;Vincenzo et al, 2014), sweet potatoes (Mano et al, 2007;Zhang et al, 2020), and carrots (Xu et al, 2019), the flesh of some apples (Chagné et al, 2013;Espley et al, 2007), kiwifruits (Wang et al, 2019), and plums (Niu et al, 2017) can accumulate abundant amounts of anthocyanins via the regulation of MYB transcription factors during their growth underground, or above the ground in the dark. After photosynthesis was interrupted, the anthocyanin synthesis was inhibited in turnip (Schneider & Stimson, 1971), corn (Kim et al, 2006), and Arabidopsis (Jeong et al, 2010).…”
