“…Overexpression of I. batatas PAL (IbPAL1) in sweet potato has been reported to increase the CGA levels in leaves (Yu et al. , 2021). Although the expansion of the secondary xylem was also stimulated in stems, the formation of storage roots was inhibited.…”

“…The main anthocyanins in sweet potato were mono- and diacylated derivatives of cyanidins and peonidins (Montilla et al, 2010 ) that were synthesized via the flavonoid pathway, which has been widely studied in a variety of plants like Arabidopsis (Lepiniec et al, 2006 ), strawberry (Aharoni et al, 2001 ), Passiflora edulis Sims (Qiu et al, 2020 ), and purple wheat (Wang et al, 2021 ). In sweet potato, the key structural genes related to the flavonoid biosynthetic pathway, such as phenylalanine ammonia lyase ( IbPAL ) (Yu et al, 2021 ), chalcone isomerase ( IbCHI ) (Guo et al, 2015 ), dihydrokaempferol reductase ( IbDHKR ) (Liu et al, 2017 ), dihydroflavonol 4 reductase ( IbDFR ) (Wang et al, 2013 ), anthocyanidin synthase ( IbANS ) (Zhou et al, 2009 ), flavonoid 3′-hydroxylase ( IbF3'H ) (Zhou et al, 2012 ), anthocyanidin 3-O-glucoside-2″-O-glucosyltransferase ( Ib3GGT ) (Wang et al, 2018b ), and UDP-glucose: flavonoid 3-O-glucosyltransferase ( IbUF3GT ) (Hu et al, 2016 ), have been isolated and verified with gene function illustration. In addition to structural genes, many transcription factors (TFs) have also been reported to regulating the expression of flavonoid biosynthetic genes.…”

“…In present study, we have found 28 genes coding PAL, among them, the expression level of 4 PAL genes (Unigene5424_All, CL182.Contig1_All, CL182.Contig30_All, Unigene66592_All) corresponded well with CGA content. Yu et al (2021) used overexpression of IbPAL1 to increase the content of CGA in sweet potato, which also confirmed the regulation effect of PAL on the synthesis of CGA (Yu et al 2021). C4H is the second enzyme of phenylpropanoid pathway after PAL, converting cinnamic acid to p-coumaric acid.…”
