“…This is not surprising because older plants have a fully developed photosynthetic apparatus and accumulate more pigments. In our experiment in sprouts grown under low temperature we determinate less carotenoids than in sprouts grown at 21 • C. It was already reported that low temperatures affect the genes related with carotenoids synthesis but likely the dynamic of carotenoid changes may be related with cultivar or plants development stage [48]. For, example, unlike our results Jurkow et al [47] reported an increase in carotenoid content in fully mature kale plants after moderate (−5 • C) and severe frost (−15 • C).…”

Consumption of plants in the juvenile stage becomes popular because sprouts are easy to grow, and they can be a tasty source of micro- and macro-nutrients and various phytochemicals. However, some environmental factors during sprout growth can affect their characteristics. In this article, we investigated how low temperatures during cultivation (8 °C) and additional exposure to freezing temperatures (−8 °C) affect the physiological status and phytochemical content of kale (Brassica oleracea var. acephala) sprouts compared to the control grown at 21 °C. We conducted five independent laboratory experiments and found that low temperature significantly increased proline content and decreased sprouts yield. In addition, low temperature caused a significant decrease in carotenoid and flavonoid content, while phenolic acid content and total glucosinolates content increased, but individual glucosinolates were differentially affected. Our results indicate that low temperatures affect the physiological status of kale sprouts and affect the content of phytochemicals.

“…The color quality of tea is the result of the combined action of chlorophyll and its transformation products, with chlorophyll as the main substance for the color formation of green tea ( Yang, Li, Teng, Han, & Zhuang, 2021 ). The difference of the five varieties in the color of dry tea was further explored by using HPLC to quantify the main components of chlorophyll and its degradation products.…”

“…To consolidate this assumption, we further investigated the transcript levels of PtCRTISO4 at different cultivation periods. It has been widely stated that many carotenogenesis genes are co-regulated ( Sun et al, 2010 ; Ma X. et al, 2018 ; Yang et al, 2021 ). In this study, the transcriptional patterns of three functionally addressed genes (i.e., PtPSY , PtZEP2 , and PtVDL1 ) and PtCRTISO4 displayed the same variation trend during the whole cultivation process, suggesting that PtCRTISO4 is likely co-regulated with other three genes and probably participates in carotenegenesis ( Kadono et al, 2015 ; Kaur and Spillane, 2015 ).…”

Nannochloropsis has been considered as a promising feedstock for the industrial production of violaxanthin. However, a rational breeding strategy for the enhancement of violaxanthin content in this microalga is still vacant, thereby limiting its industrial application. All-trans-lycopene locates in the first branch point of carotenogenesis. The carotenoid isomerase (CRTISO), catalyzing the lycopene formation, is thus regarded as a key enzyme for carotenogenesis. Phaeodactylum tricornutum can accumulate high-level carotenoids under optimal conditions. Therefore, it is feasible to improve violaxanthin level in Nannochloropsis by overexpression of PtCRTISO. Protein targeting analysis of seven PtCRTISO candidates (PtCRTISO1–6 and PtCRTISO-like) demonstrated that PtCRTISO4 was most likely the carotenoid isomerase of P. tricornutum. Moreover, the transcriptional pattern of PtCRTISO4 at different cultivation periods was quite similar to other known carotenogenesis genes. Thus, PtCRTISO4 was transformed into N. oceanica. Compared to the wild type (WT), all three transgenic lines (T1–T3) of N. oceanica exhibited higher levels of total carotenoid and violaxanthin. Notably, T3 exhibited the peak violaxanthin content of 4.48 mg g–1 dry cell weight (DCW), which was 1.68-folds higher than WT. Interestingly, qRT-polymerase chain reaction (PCR) results demonstrated that phytoene synthase (NoPSY) rather than ζ-carotene desaturase (NoZDS) and lycopene β-cyclase (NoLCYB) exhibited the highest upregulation, suggesting that PtCRTISO4 played an additional regulatory role in terms of carotenoid accumulation. Moreover, PtCRTISO4 overexpression increased C18:1n-9 but decreased C16:1n-7, implying that C18:1 may serve as a main feedstock for xanthophyll esterification in Nannochloropsis. Our results will provide valuable information for the violaxanthin production from Nannochloropsis.
