Plant pigmentation is affected by a variety of factors. Light, an important plant developmental signal, influences the accumulation of anthocyanins primarily through the activation of the transcription factors that regulate the flavonoid biosynthetic pathway. In this study, we utilized maize Black Mexican ...
Flavonoids, due to their pharmacological attributes, have recently become target molecules for metabolic engineering in commonly consumed food crops. Strategies including expression of single genes and gene pyramiding have provided only limited success,
Moreover, it investigated whether the relative ratio of blue and red LEDs would impact the growth, physiology and chemical profile of lettuce compared to a full white spectrum. Finally, the impact of supplementing the blue/red growth lights with UV, far-red and green LEDs was also investigated...
yellow and red nets to alter the light intensity and light spectral composition in the fields. Flavonol glycosides are more sensitive to light intensity than catechins, with a reduction percentage of total flavonol glycosides up to 79.6% compared with 38.7% of total catechins under shade treatment....
Figure 1.The light spectrum in the wavelength region λ 380 ÷ 780 nm was determined at about 80 cm from the light sources. 2.3. Biometric Determinations All the plants in each pot were considered as one replicate; therefore, the samples from each pot were jointly collected and the biometric...
The Ti 2p region at the TiO2 sample spectrum (see Figure 2a) exhibited two characteristic peaks at binding energies 459.6 eV and 465.2 eV, associated with Ti 2p3/2 and Ti 2p1/2 of Ti4+ ions in oxide lattice, respectively [27]. The O 1s region (see Figure 2b) on the spectrum shows...
Gel permeation chromatography (GPC) measurements were conducted with a water 410 GPC (Waters, Milford, PA, USA) equipped with Waters styragel column (HT4 + HT3) using THF as the eluent; the molecular weights were calibrated with polystyrene standards, and the Nanomaterials 2020, 10, 467 3 ...
The spectra were acquired in attenuated total reflectance (ATR) mode in the spectral range of 4000–450 cm−1 using Perkin Elmer Waltham, MA, USA) Spectrum Two spectrophotometer equipped with a diamond ATR crystal. The morphology of the samples at the micro-scale level was investigated using ...
Waters Empower 3 software (Waters, Milford, MA, USA) was used for data processing. The total tocopherol content (µg per g of DW tissue) was obtained by adding up the levels of the three detected tocopherols. 3.3.2. Sugars All 24 exocarp samples from the mature stage (10 mg DW) ...
