“…BL help to induce the biosynthesis of the functional metabolite such as long embryogenic calli, catechins, rutin, anthocyanin, etc., and MYB, HY5, MYC2, bHLH, and PIF4 are the principal regulators (Li et al, 2019;. This BL was also better than RL to promote the biosynthesis of carotenoids by the upregulation of correlated genes in tea plants (Tian et al, 2021).…”

Light is one of the most prestigious environmental sign, which stimulates plant metabolite consequences. Zhong Ming 6 (ZM6) is a green tea (Camellia sinensis) cultivar with highly accumulating TGGP. Here, three kinds of supplemental light wavelengths including blue light (BL,200 µmol m−2 s−1), red light(RL,200 µmol m−2 s−1), and White Light (WL/CK, 200 µmol m−2 s−1) were applied to explore their effects on the transcriptomes and metabolomics of young shoots (one bud and two leaves) in tea plants. Interestingly, artificial BL and RL significantly affect the secondary metabolites and transcriptome factors of tea plants. Here, BL extensively dominated the multiple physiological actions with secondary metabolism. In addition, RL could induce plant growth, development, and photosynthesis. Thoroughly, the identification of eight structural genes and 34 transcription factors (TFs) signiଁcantly correlated with total catechin (TC) and anthocyanin. Due to the upregulations of the CsGSTF1 gene in the flavonoid biosynthesis pathway, anthocyanin production was maximum under BL. Then, CsMYB75, bHLH-MYC, and other R2R3-MYBs were highly upregulated in BL to increase the accumulation of TC and anthocyanins in tea plants. Again, the CsMYB4 gene was highly significant and positively correlated with TC and anthocyanin accumulation under RL. We indicated that BL is more feasible due to the number of functional metabolites (gallic acid, caffeine, TC, TGGP (1, 2, 6-tri-O-galloyl-β-D-glucopyranose), and anthocyanin) being supreme. For taste, quality, and dynamic indigenous mechanism of the tea plant, RL is also suitable that increase Chlorophyll content and tea yield.

“…ABA plays an important role in plant growth and development and stress adaptation and also has an impact on leaf color mutations, with overexpression of rice NAC transcription factor ONAC054 under dark and ABA treatment [ 41 ]. ABA is a key regulator of anthocyanin synthesis during the tea leaf color transition, and the related genes involved in ABA signaling were significantly and positively correlated with the photoperiod, indicating that illumination plays an important role for ABA in regulating leaf color [ 42 , 43 ].…”

The rice leaf color mutant B03S was previously generated from the photoperiod- and thermo-sensitive genic male sterile (PTGMS) rice line Efeng 1S, of which male sterility manifests by photoperiod and temperature but exhibits mainly temperature-sensitive characteristics. After these plants were deeply transplanted, the new leaves manifested typical zebra stripe patterns. Here, B03S was subjected to deep and shallow transplanting, shading with soil and aluminum foil, and control conditions in situ to determine the cause of the striped-leaf trait. The direct cause of striped leaves is the base of the leaf sheath being under darkness during deep transplanting, of which the critical shading range reached or exceeds 4 cm above the base. Moreover, typical striped leaves were analyzed based on the targeted metabolome method by ultra-performance liquid chromatography/tandem mass spectrometry (UPLC–MS/MS) combined with transcriptome and real-time quantitative PCR (qPCR)-based verification to clarify the metabolic pathways and transcriptional regulation involved. Carotenoids enter the xanthophyll cycle, and the metabolites that differentially accumulate in the striped leaves include zeaxanthin and its derivatives for photooxidative stress protection, driven by the upregulated expression of OsZEP. These findings improve the understanding of the physiological and metabolic mechanisms underlying the leaf color mutation in rice plants, enrich the theoretical foundation of the nonuniform leaf color phenomenon widely found in nature and highlight key advancements concerning rice production involving the transplanting of seedlings or direct broadcasting of seeds.

“…Under different wavelength light treatment, the color of “Huangjinya” leaves will change, which display that white and blue light can effectively keep the yellow of leaves, while red light makes the leaves of “Huangjinya” green. The contents of chlorophyll-a and chlorophyll-b in the second leaf of Huangjinya treated with red light (610–720 nm) increase by 1.54 and 2.44 times, respectively, and compared with white light treatment, the effects of blue light treatment on the contents of chlorophyll and carotenoids in the second leaf were not obvious (Tian et al 2021 ). One hypothesis of the effect of monochromatic light on the leaf color of “Huangjinya” is that red light promotes the synthesis of chlorophyll (Ernesto Bianchetti et al 2018 ; Gupta et al 2014 ).…”

Review: the effect of light on the key pigment compounds of photosensitive etiolated tea plant

Background Light is the ultimate energy source of plant photosynthesis, which has an important impact on the growth, development, physiology and biochemistry of tea plant. Photosensitive etiolated tea plant belongs to a kind of colored leaf plant, which is a physiological response to light intensity. Compared with conventional green bud and leaf of tea plant, the accumulation of pigment compounds (chlorophyll and carotenoids, etc.) closely related to a series of reactions of photosynthesis in photosensitive etiolated tea plant is reduced, resulting in the difference of leaf color of tea. This specific tea resource has high application value, among which high amino acid is one of its advantages. It can be used to process high-quality green tea with delicious taste and attractive aroma, which has been widely attention. The mechanism of the color presentation of the etiolated mutant tea leaves has been given a high topic and attention, especially, what changes have taken place in the pigment compounds of tea leaves caused by light, which makes the leaves so yellow. At present, there have been a lot of research and reports. Purpose of the review We describe the metabolism and differential accumulation of key pigment compounds affecting the leaf color of photosensitive etiolated tea that are triggered by light, and discuss the different metabolism and key regulatory sites of these pigments in different light environments in order to understand the “discoloration” matrix and mechanism of etiolated tea resources, answer the scientific question between leaf color and light. It provides an important strategy for artificial intervention of discoloration of colored tea plant. Conclusion The differential accumulation of pigment compounds in tea plant can be induced phytochrome in response to the change of light signal. The synthesis of chlorophyll in photoetiolated tea plants is hindered by strong light, among which, the sites regulated by coproporphyrinogen III oxidase and chlorophyllide a oxidase is sensitive to light and can be inhibited by strong light, resulting in the aggravation of leaf etiolation. The phenomenon can be disappeared or weakened by shading or reducing light intensity, and the leaf color is greenish, but the increase of chlorophyll-b accumulation is more than that of chlorophyll-a. The synthesis of carotenoids is inhibited strong light, and high the accumulation of carotenoids is reduced by shading. Most of the genes regulating carotenoids are up-regulated by moderate shading and down-regulated by excessive shading. Therefore, the accumulation of these two types of pigments in photosensitive etiolated tea plants is closely related to the light environment, and the leaf color phenotype shape of photosensitive etiolated tea plants can be changed by different light conditions, which provides an important strategy for the production and management of tea plant.
