Abstract
Flavane-3-ol monomers are the precursors of proanthocyanidins (PAs), which play a crucial role in grape resistance. Previous studies showed that UV-C positively regulated leucoanthocyanidin reductase (LAR) enzyme activity to promote the accumulation of total flavane-3-ols in juvenile grape fruit, but its molecular mechanism was still unclear. In this paper, we found that the contents of flavane-3-ol monomers increased dramatically at the early development stage grape fruit after UV-C treatment, and the expression of its related transcription factor VvMYBPA1 was also enhanced significantly. The contents of (-)-epicatechin and (+)-catechin, the expression level of VvLAR1 and VvANR, and the activities of LAR and anthocyanidin reductase (ANR) were improved significantly in the VvMYBPA1 overexpressed grape leaves compared to the empty vector. Both VvMYBPA1 and VvMYC2 could interact with VvWDR1 using bimolecular fluorescence complementation (BiFC) and yeast two hybrid (Y2H). Finally, VvMYBPA1 was proven to bind with the promoters of VvLAR1 and VvANR by yeast one hybrid (Y1H). To sum up, we found that the expression of VvMYBPA1 increased in the young stage of grape fruit after UV-C treatment. VvMYBPA1 formed a trimer complex with VvMYC2 and VvWDR1 to regulate the expression of VvLAR1 and VvANR, thus positively promoting the activities of LAR and ANR enzyme, and eventually improved the accumulation of flavane-3-ols in grape fruit.

Abstract
Leucoanthocyanidin reductase (LAR) is the critical enzyme in the synthesis pathway of proanthocyanidins, which are the primary pigments in brown cotton fibers. Our previous study has revealed significant differences in the expression levels of GhLAR1 between white and brown cotton fibers at 10 DPA. In this work, the expression pattern of the GhLAR1 gene was further studied, and the promoter of GhLAR1 (1780 bp) was isolated and characterized. Bioinformatic analysis indicated that GhLAR1 promoter contained many known light response elements and several defenses related to transcriptional factor-binding boxes, which may partially explain the response of the GhLAR1 to temperature, NaCl, and PEG treatments. Furthermore, GhLAR1 was preferentially and strongly expressed in fibers and flowers of cotton, and the expression levels in all tested tissues (especially fibers) of brown cotton were significantly higher than those in white cotton. Consistent with the expression analysis, the GhLAR1 promoter mainly drove GUS expression in epidermal trichomes and floral organs.

Abstract
Proanthocyanidins (PAs) and anthocyanins are involved in the response of plants to various environmental stresses. However, the mechanism behind defense-induced PA biosynthetic regulation is still not completely elucidated, also in grapevine. This study performed a transcriptome sequencing analysis of grape berries infected with Colletotrichum gloeosporioides to highlight the induction of the VabHLH137 factor from the basic helix-loop-helix (bHLH) XII subfamily by the fungus, which appeared to be significantly co-expressed with PA-related genes. The functional analysis of VabHLH137 overexpression and knockdown in transgenic grape calli showed that it positively regulated PA and anthocyanin biosynthesis. Moreover, VabHLH137 overexpression in the grape calli significantly increased resistance to C. gloeosporioides. A yeast one-hybrid and electrophoretic mobility shift assay revealed that VabHLH137 directly bound to the VaLAR2 promoter, enhancing its activity and interacting with VaMYBPAR, a transcriptional activator of PA biosynthesis. Furthermore, transient experiments showed that although the VabHLH137 + VaMYBPAR complex activated VaLAR2 expression, it failed to further enhance VaLAR2 expression compared to VaMYBPAR alone. The findings indicated that VabHLH137 enhanced PA biosynthesis by activating of VaLAR2 expression, providing new insight into the transcriptional regulation of defense-induced PA biosynthesis in grapevine.

Abstract
Virus-induced gene silencing (VIGS) technology was applied to silence VvANR in cv. Zaoheibao grape berries, and the effects of VvANR silencing on berries phenotype; gene expression level of ANS, LAR1, LAR2, and UFGT; enzyme activity of ANS; and accumulations of anthocyanin and flavan-3-ol were investigated. At the third day after treatment, the VvANR silenced grape berries began to turn red slightly, which was 2 days earlier than that of the control group. And the flavan-3-ol content in VvANR-silenced grape berries had been remarkable within 1 to 5 days, the ANR enzyme activity in VvANR-silenced grapes extremely significantly decreased in 3 days, and LAR enzyme activity also decreased, but the difference was not striking. The ANS enzyme activity of the transformed berries was significantly higher than that of the control after 3 days of infection, and it was exceedingly significantly higher than that of the control after 5 to 10 days. The content of anthocyanin in transformed berries increased of a very marked difference within 3 to 15 days. pTRV2-ANR infection resulted in an extremely significant decrease in the expression of VvANR gene, and the expression of VvLAR1, VvLAR2, VvMYBPA1, VvMYBPA2, and VvDFR were also down-regulated. However, the expression of VvANS and VvUFGT was up-regulated significantly. After VvANR silencing via VIGS, VvANR expression in grape berries was extremely significantly decreased, resulting in decreased ANR enzyme activity and flavan-3-ol content; berries turned red and deeper in advance. In addition, VvANR silencing can induce up-regulation of VvANS and VvUFGT expression, significantly increase ANS enzyme activity, and increase of anthocyanin accumulation.

Abstract
BACKGROUND AND OBJECTIVE Anthocyanin is responsible for the red color of apple. Ultraviolet light plays a key role in activating the genes responsible for anthocyanin biosynthesis. However, the most important concern is using UV light irradiation on fruit to increase anthocyanins level and its nutritional quality. In this study, the accumulation of anthocyanin in green apple using UV-B and UV-C was investigated and its biological influence was evaluated in rats. MATERIAL AND METHOD Green Golden delicious apples were irradiated with doses of UV-C and UV-B light for a period of 3 h/day each for 3 days. Two Groups of rats were fed on balanced diet or balanced diet supplemented with 10% apple exposure to UV (AP-UV) for a month. RESULTS The HPTLC and spectrophotometric determination of anthocyanin revealed that color development was significantly increased by 90% in treated apple compared to the control apples. Histological difference was observed between the 2 groups. Plasma levels of uric acid, the activity of transaminases (ALT and AST) as well as malondialdehyde (MDA) were significantly elevated in AP-UV rats. Plasma total cholesterol, triglycerides and creatinine level did not differ among the 2 groups. Liver MDA and catalase levels were eminent in AP-UV rats compared to control. Gene expression of selected inflammatory cytokines (TNF-α, IL-6 and IL-1β) was significantly up-regulated in liver of AP-UV rats in comparison to control rats. CONCLUSION The result revealed that there is a health-hazard linked to feeding rats on diet containing irradiated-apple with UV-B and UV-C, which represented by body weight reduction, inflammation development, liver function and oxidative stress elevation.

Abstract
Berry fruits are well known to contain large amounts of polyphenol compounds. Among them, flavan-3-ol derivatives are a group of secondary metabolism compounds currently attracting a great deal of attention owing to their health benefits. Not only the fruits, but also the leaves of raspberry plants, are highly esteemed for tea making around the world and are largely used for food. In this report, we discuss the results of our study on the effect of light and temperature on polyphenol accumulation in raspberry leaves. When raspberry was cultivated in a plant factory unit and light intensity, wavelength, and temperature were varied, the amount of total polyphenol increased under blue light. Quantitative determination of (+)-catechin, (⁻)-epicatechin, procyanidin B4, flavan-3-ol trimer, which are flavan-3-ol derivatives, was carried out using HPLC, whereby we confirmed their increase under blue light. Semi-quantitative RT-PCR showed correlation between chalcone synthase (CHS) gene expression and the amounts of the compounds measured in the leaves.

Abstract
Ultraviolet (UV) irradiation has been related to the extension shelf-life and maintenance of postharvest quality in fruits. However, the comparison of UV-B and UV-C treatment on the biosynthesis of phenolic compounds of grape remain unclear. This study provides a comparison on the mechanism of phenolic secondary metabolism at the same dose of 3.6 kJ m-2 UV treatment. Total phenolic compounds, total flavonoid, total flavanol, and total anthocyanin content and antioxidant activities of grapes after UV-C treatments were higher than those of the control and UV-B treatment. Among the evaluated parameters of individual phenolic compounds, the content of trans-resveratrol showed the highest percentage increase after the UV application. The transcriptions of PAL, CHS, F3H, LAR, ANS and STS were higher in grapes treated by UV-C than in those treated by UV-B. The CHS, LAR, ANS and STS genes were more induced in UV-B treatment than in control group. The same applied dose of UV-B or UV-C irradiation have different impact on gene expression and phenolic metabolites synthesis. The UV-C irradiation stimulated a higher gene expression of the phenolic compounds biosynthesis and also induced a greater accumulation of these metabolites at the same applied dose.

Abstract
Anthocyanins and proanthocyanidins (PAs) are crucial factors that affect the quality of grapes and the making of wine, which were stimulated by various stimuli and environment factors (sugar, hormones, light, and temperature). The aim of the study was to investigate the influence of exogenous 24-Epibrassinolide (EBR) and light on the mechanism of anthocyanins and PAs accumulation in grape berries. Grape clusters were sprayed with EBR (0.4 mg/L) under light and darkness conditions (EBR + L, EBR + D), or sprayed with deionized water under light and darkness conditions as controls (L, D), at the onset of veraison. A large amount of anthocyanins accumulated in the grape skins and was measured under EBR + L and L treatments, whereas EBR + D and D treatments severely suppressed anthocyanin accumulation. This indicated that EBR treatment could produce overlay effects under light, in comparison to that in dark. Real-time quantitative PCR analysis indicated that EBR application up-regulated the expression of genes (VvCHI1, VvCHS2, VvCHS3, VvDFR, VvLDOX, VvMYBA1) under light conditions. Under darkness conditions, only early biosynthetic genes of anthocyanin biosynthesis responded to EBR. Furthermore, we also analyzed the expression levels of the BR-regulated transcription factor VvBZR1 (Brassinazole-resistant 1) and light-regulated transcription factor VvHY5 (Elongated hypocotyl 5). Our results suggested that EBR and light had synergistic effects on the expression of genes in the anthocyanin biosynthesis pathway.

Abstract
Flavan-3-ol derivatives are common plant-derived bioactive compounds. In particular, (-)-epigallocatechin-3-O-gallate shows various moderate biological activities without severe toxicity, and its health-promoting effects have been widely studied because it is a main ingredient in green tea and is commercially available at low cost. Although various biologically active flavan-3-ol derivatives are present as minor constituents in plants as well as in green tea, their biological activities have yet to be revealed, mainly due to their relative unavailability. Here, I outline the major factors contributing to the complexity of functionality studies of flavan-3-ol derivatives, including proanthocyanidins and oligomeric flavan-3-ols. I emphasize the importance of conducting structure-activity relationship studies using synthesized flavan-3-ol derivatives that are difficult to obtain from plant extracts in pure form to overcome this challenge. Further discovery of these minor constituents showing strong biological activities is expected to produce useful information for the development of functional health foods.
