“…Accumulation of anthocyanins in fruits in response to light is mediated by a R2R3 MYB transcription factor in many plants including apple, litchi, pear, Chinese bayberry, and eggplant (Bai et al, ; M. Jiang, Ren, Lian, Liu, & Chen, ; Lai et al, ; Niu et al, ; Takos et al, ). HY5 is a basic leucine zipper (bZIP) transcription factor involved in light‐induced anthocyanin biosynthesis by directly binding to the G‐box motif within the promoter of R2R3 MYB regulators of anthocyanin biosynthesis and promoting anthocyanin accumulation (An et al, ; M. Jiang et al, ; Qiu et al, ; Shin et al, ). In combination with HY5 protein, B‐box containing zinc‐finger proteins were shown to activate anthocyanin genes in Arabidopsis and red pear (Bai et al, ; D. Xu et al, ).…”

Blood orange is generally recognized to accumulate anthocyanins in its fruit pulp in a cold‐inducible manner. We observed that the fruit peel of blood orange can also accumulate anthocyanins under ample light conditions. Interestingly, purple pummelo can accumulate anthocyanins only in its fruit peel but not in its pulp. The mechanism underlying the tissue specificity of anthocyanin accumulation in citrus is unknown. Here, we show that the active promoter of Ruby1, a key activator of anthocyanin biosynthesis, is also light inducible in addition to its already known cold inducibility in blood orange. Electrophoretic mobility shift assays and transient expression assays showed that HY5 positively regulated the transcription of Ruby1 by binding to the G‐box motif (CACGTC). The tissue specificity of anthocyanin accumulation in the peel of purple pummelo may be due to the lack of a low temperature responsive element and a MYC binding site, which were shown to be involved in cold inducibility of CsRuby1 in blood orange by insertion of a long terminal repeat type retrotransposon in the promoter. These results bring new insights into the regulatory mechanism of anthocyanin biosynthesis in response to environmental stimuli and provide cis‐elements for genetic improvement of anthocyanin‐stable fruits rich in antioxidant metabolites.

“…The regulation mechanisms of light on secondary metabolite biosynthesis like anthocyanin were studied in recent years. In eggplant ( Solanum melongena L.), light regulated anthocyanin accumulation by way that SmCRY interaction with SmCOP1 prevented E3 ligase activity of SmCOP1 for ubiquitinating and degrading SmHY5 and SmMYB1 (Jiang et al, 2016). Consequently, SmHY5 and SmMYB1 accumulated and combined with the promoters of downstream anthocyanin synthesis genes ( SmCHS and SmDFR ) in light (Jiang et al, 2016).…”

Artemisinin is a sesquiterpene lactone endoperoxide extracted from a traditional Chinese medicinal plant Artemisia annua. Artemisinin-based combination therapies (ACTs) are recommended as the best treatment of malaria by the World Health Organization (WHO). Both the phytohormone jasmonic acid (JA) and light promote artemisinin biosynthesis in A. annua. Interestingly, we found that the increase of artemisinin biosynthesis by JA was dependent on light. However, the relationship between the two signal pathways mediated by JA and light remains unclear. Here, we collected the A. annua seedlings of 24 h continuous light (Light), 24 h dark treatment (Dark), 4 h MeJA treatment under the continuous light conditions (Light-MeJA-4h) and 4 h MeJA treatment under the dark conditions (Dark-MeJA-4h) and performed the transcriptome sequencing using Illumina HiSeq 4000 System. A total of 266.7 million clean data were produced and assembled into 185,653 unigenes, with an average length of 537 bp. Among them, 59,490 unigenes were annotated and classified based on the public information. Differential expression analyses were performed between Light and Dark, Light and Light-MeJA-4h, Dark and Dark-MeJA-4h, Light-MeJA-4h, and Dark-MeJA-4h, respectively. Furthermore, transcription factor (TF) analysis revealed that 1588 TFs were identified and divided into 55 TF families, with 284 TFs down-regulated in the Dark relative to Light and 96 TFs up-regulated in the Light-MeJA-4h relative to Light. 8 TFs were selected as candidates for regulating the artemisinin biosynthesis and one of them was validated to be involved in artemisinin transcriptional regulation by Dual-Luciferase (Dual-LUC) assay. The transcriptome data shown in our study offered a comprehensive transcriptional expression pattern influenced by the MeJA and light in A. annua seedling, which will serve as a valuable resource for further studies on transcriptional regulation mechanisms underlying artemisinin biosynthesis.

The phenotypes associated with plant photomorphogenesis such as the suppressed shade avoidance response and de-etiolation offer the potential for significant enhancement of crop yields. Of many light signal transducers and transcription factors involved in the photomorphogenic responses of plants, this review focuses on the transgenic overexpression of the photoreceptor genes at the uppermost stream of the signalling events, particularly phytochromes, crytochromes and phototropins as the transgenes for the genetic engineering of crops with improved harvest yields. In promoting the harvest yields of crops, the photoreceptors mediate the light regulation of photosynthetically important genes, and the improved yields often come with the tolerance to abiotic stresses such as drought, salinity and heavy metal ions. As a genetic engineering approach, the term photo-biotechnology has been coined to convey the idea that the greater the photosynthetic efficiency that crop plants can be engineered to possess, the stronger the resistance to biotic and abiotic stresses. Development of GM crops based on photoreceptor transgenes (mainly phytochromes, crytochromes and phototropins) is reviewed with the proposal of photo-biotechnology that the photoreceptors mediate the light regulation of photosynthetically important genes, and the improved yields often come with the added benefits of crops' tolerance to environmental stresses.
