“…Numerous studies have shown that light exposure can enhance the anthocyanin accumulation in fruit skin [21,22]. In addition to light intensity, light quality also influences the concentration of anthocyanins in fruits of many plant species.…”

Lily tepals have a short lifespan. Once the tepals senesce, the ornamental value of the flower is lost. Some cultivars have attractive purple ovaries and fruits which greatly enhance the ornamental value of Asiatic hybrid lilies. However, little is known about the molecular mechanisms of anthocyanin biosynthesis in Asiatic hybrid lily ovaries. To investigate the transcriptional network that governs purple ovary coloration in Asiatic hybrid lilies, we obtained transcriptome data from green ovaries (S1) and purple ovaries (S2) of Asiatic “Tiny Padhye”. Comparative transcriptome analysis revealed 4228 differentially expressed genes. Differential expression analysis revealed that ten unigenes including four CHS genes, one CHI gene, one F3H gene, one F3′H gene, one DFR gene, one UFGT gene, and one 3RT gene were significantly up-regulated in purple ovaries. One MYB gene, LhMYB12-Lat, was identified as a key transcription factor determining the distribution of anthocyanins in Asiatic hybrid lily ovaries. Further qPCR results showed unigenes related to anthocyanin biosynthesis were highly expressed in purple ovaries of three purple-ovaried Asiatic hybrid lilies at stages 2 and 3, while they showed an extremely low level of expression in ovaries of three green-ovaried Asiatic hybrid lilies during all developmental stages. In addition, shading treatment significantly decreased pigment accumulation by suppressing the expression of several unigenes related to anthocyanin biosynthesis in ovaries of Asiatic “Tiny Padhye”. Lastly, a total of 15,048 Simple Sequence Repeats (SSRs) were identified in 13,710 sequences, and primer pairs for SSRs were designed. The results could further our understanding of the molecular mechanisms of anthocyanin biosynthesis in Asiatic hybrid lily ovaries.

“…These results corresponded with the previous results in which MYBA1 positively and MYB4 negatively affected expression of DFR and UFGT (de Rosas et al ). The transcription levels of MYBA2 and UFGT had similar patterns at the onset of skin colour development in Kyoho grapes (Shinomiya et al ).…”

Background and Aims Burdock fructooligosaccharides (BFO) is an elicitor that induces biotic resistance and delays colour development in grapes postharvest. The mechanism of the delayed colour development requires further study. Methods and Results Colour development index; anthocyanin, tannin, flavonol, flavanol, trans‐resveratrol and lignin; the trans‐resveratrol, lignin and anthocyanin biosynthesis‐related transcription factors; and functional gene expression were investigated. In response to BFO induction, upregulation of the v‐myb avian myeloblastosis viral oncogene homologue 14 (MYB14)‐mediated stilbene synthase (STS) altered the phenylpropanoid fluxes from anthocyanin to trans‐resveratrol; MYBA1 and MYBA2‐mediated the downregulation of dihydroflavonol 4‐reductase (DFR), and flavonoid‐3‐O‐glycosyltransferase (UFGT) limited anthocyanin biosynthesis. Downregulation of MYB4‐mediated chalcone synthase (CHS) and upregulation of cinnamoyl CoA reductase (CCR) and cinnamyl alcohol dehydrogenase (CAD) altered the phenylpropanoid fluxes from anthocyanin to lignin. Conclusions Burdock fructooligosaccharides inhibits postharvest colour development in grapes by altering the phenylpropanoid fluxes from anthocyanin to resistance‐related phenolic substances. Significance of the Study Understanding the mechanism of the effect of BFO on grape colour development may improve our understanding of colour development in grape berries.

“…Thus, the production of grapes with beautiful colors has attracted increasing interestfrom both farmers and researchers. However, the coloration of grapes is greatly affected by environmental factors, such as high temperature [10]. In this situation, exogenous agents, especially plant growth regulators that help promote grape coloration [11], are the best choice for coloration improvement.…”

Pigment content is an important quality attribute in the grape industry, and anthocyanins are the major fruit pigments. iso-PhABA is a novel and excellent ABA analog capable of the antimetabolic inactivation of ABA. In this study, we found that iso-PhABA improved the coloration of grape berries more obviously than ABA at concentrations of 2 mg/L and 5 mg/L in two grape varieties in China. iso-PhABA treatment enhanced the anthocyanin content in the two grape varieties; specifically, the anthocyanin and delphinidin contents increased in both the 'Jufeng' and 'Xiahei' varieties. An enzymatic activity test showed that iso-PhABA significantly promoted four key enzyme activities catalyzing anthocyanin biosynthesis. We also determined the affinity between iso-PhABA and ABA receptors using ABA as a control. The results indicated that iso-PhABA had significantly to moderately higher affinities for some ABA receptors, including PYR1, PYL2, PYL1, PYL3 and PYL10, which resulted in higher inhibition of the PP2C HAB1 in the presence of iso-PhABA than in the presence of ABA. iso-PhABA treatment increased the content of soluble sugars and grape yield without any apparent accompanying adverse effects on the quality of the grapes.
