Fruit ripening is usually accompanied by anthocyanin accumulation. Ethylene is key in ripening-induced anthocyanin production in many fruits. However, the effects of fruit ripening and ethylene on anthocyanin biosynthesis in purple tomato fruits are unclear. This study shows that bagged fruits of the purple tomato cultivar ‘Indigo Rose’ failed to produce anthocyanins at the red ripening stage after bag removal. In contrast, the bagged immature fruits accumulated a significant amount of anthocyanins after removing the bags. The transcriptomic analyses between immature and red ripening fruit before and after bag removal revealed that anthocyanin-related genes, including the key positive R2R3-MYB regulator SlAN2-like, were repressed in the red ripening fruit. The 86 identified transcription factors, including 13 AP2/ERF, 7 bZIP, 8 bHLH and 6 MYB, showed significantly different expressions between immature and red ripening fruits. Moreover, subjecting bagged immature fruits to exogenous ethylene treatment significantly inhibited anthocyanin accumulation and the expression of anthocyanin-related genes, including the anthocyanin structure genes and SlAN2-like. Thus, ethylene inhibits anthocyanin biosynthesis by repressing the transcription of SlAN2-like and other anthocyanin-related genes. These findings provide new insights into anthocyanin regulation in purple tomato fruit.

“…Far-red light had no effect on antioxidant potential of berries (Figure 2D). The role of environmental factors, such as specific light irradiation wavelengths, can potentially determine the total phenolic profile of the berries toward higher antioxidant potential (Ma et al, 2021a). While comparing both ripening conditions upon metabolites accumulation, the biochemical regulatory networks and signals from other source tissues is Frontiers in Plant Science 07 frontiersin.org usually altered in detached conditions, when compared with attached fruits.…”

“…The spectral wavelengths from the solar radiation are perceived by specific plant photoreceptors that interact upon constitutive photomorphogenesis (COP1) protein, which is one of the key controllers of photomorphogenesis (Wu et al, 2019). COP1 interacts with light-inducible proteins, such as suppressor of phytochrome-A (SPA1), forming complexes that lead to a tightly regulated signal cascade mechanism resulting in changes in the expression of both regulatory and structural genes of the flavonoid biosynthetic pathway (Ma et al, 2021a). The COP1 repressor specifically acts in the degradation of some known positive regulators of anthocyanin biosynthesis, such as elongated hypocotyl 5 (HY5) and MYB transcription factors under altering light and dark conditions (Lu et al, 2017;Ma et al, 2021b).…”

Light spectral quality is known to affect flavonoid biosynthesis during fruit ripening. However, the response of fruits to different light conditions, when ripening autonomously from the parent plant (detached), has been less explored. In this study, we analyzed the effect of light quality on detached and naturally ripening (attached) non-climacteric wild bilberry (Vaccinium myrtillus L.) fruits accumulating high amounts of anthocyanins and flavonols. Our results indicated contrasting responses for the accumulation of phenolic compounds in the berries in response to red and blue light treatments. For detached berries, supplemental blue light resulted in the highest accumulation of anthocyanins, while naturally ripening berries had elevated accumulation under supplemental red light treatment. Both red and blue supplemental light increased the expression levels of all the major structural genes of the flavonoid pathway during ripening. Notably, the key regulatory gene of anthocyanin biosynthesis, VmMYBA1, was found to express fivefold higher under blue light treatment in the detached berries compared to the control. The red light treatment of naturally ripening berries selectively increased the delphinidin branch of anthocyanins, whereas in detached berries, blue light increased other anthocyanin classes along with delphinidins. In addition, red and far-red light had a positive influence on the accumulation of flavonols, especially quercetin and myricetin glycoside derivatives, in both ripening conditions. Our results of differential light effects on attached and detached berries, which lacks signaling from the mother plant, provide new insights in understanding the light-mediated regulatory mechanisms in non-climacteric fruit ripening.

“…According to the research of Arabidopsis, flavonoids biosynthetic genes (CHS, CHI, F3H, F3′H, and FLS, DFR, ANS/LDOX, UFGT) are directly or indirectly regulated by R2R3-MYB transcription factors [49][50] MBW complex (R2R3-MYBs such as MYB75, MYB90, MYB113, and MYB114, bHLH, and WD40) [51][52], NAC [53], WRKY [41], SPL [43] transcription factors in response to various stimulus, such as stresses [54], light [55], UV [56], temperature [57].…”

Background Artemisia plants are widely distributed in East Asia. Though the Artemisia cultivars are commonly used as raw materials of medicine, food or moxibustion in China, most of the potential medical and nutritional ingredients, especially flavonoids ingredients are largely unknown, which imped further utilization of these cultivars.Results In this study, two Artemisia cultivars usually used as the source of moxibustion or food, named NYSY and NYYY were investigated. NYSY and NYYY were authenticated as A.argyi based on molecular data. In all detected 882 metabolic ingredients, nearly half of biological ingredients varied between two cultivars. Most of potential medical ingredients, especially flavonoids (flavone, flavonol, isoflavone, and anthocyanin) were up regulated in NYYY. The contents of total flavonoids and their antioxidant activities were also higher in NYYY. In addition, transcriptional evidences showed that more than half of flavonoids synthesis genes were up regulated in NYYY, and their putative transcription factors members of MYB, bHLH, bZIP, WRKY, NAC and MADS families were uncovered.Conclusions In all, our results provide metabolome and transcriptome evidence to underly the biochemical ingredients, especially flavonoids variation in two Artemisia cultivars. This study provides scientific evidence for the utilizing and improving the quality of Artemisia cultivars in the future.
