“…This probably occurred because the amino acid L-phenylalanine is the progenitor of many CGs, including prunasin (Ganjewala et al 2010), and is also the precursor for biosynthesis of many phenolic compounds, where the PAL is the first enzyme in this pathway (Wang et al 2012;Irisarri et al 2016). Hypothesis strengthened by the high correlation (r = 0.79; p < 0.01) between these compounds in the rootstock (Table 3).…”

“…The main source of phenolics synthesized in plants is the phenylpropanoid pathway, in which PAL is considered as key enzyme (Wang et al 2012). PAL catalyzes the deamination of phenylalanine for the production of trans-cinnamic acid, which is subsequently converted to p-coumaric acid by an oxidation reaction catalyzed by cinnamate 4-hydroxylase (C4H).…”

“…Nocito et al (2010) found evidence that the graft incompatibility between pear (Pyrus communis) and quince (Cydonia oblonga), occurs by a dysfunction of the respiratory pathway, causing respiration to follow an alternative pathway that includes the alternative oxidase enzyme (AOX), and that can be caused by cyanogenesis. This behavior has been related to different forms of stress and resulted in secondary oxidative damage due to accumulation of reactive oxygen species (ROS) (Pellinen et al 2002, Wang et al 2012Irisarri et al 2015). When the increase of ROS is relatively small, the antioxidant capacity of the cells is sufficient to maintain the balance between synthesis and degradation (Van Breusegem and Dat 2006).…”

“…Light is an exogenous signal that induces several adaptive responses in plants (Wang et al, 2012). Macedo et al (2011) found that blue light induced a higher number of leaves per plant, and red light triggered an increase in the fresh and dry weights of Alternanthera brasiliana Kuntze leaves.…”

Anacardium othonianum Rizz., popularly known as the Cerrado cashew tree, is widely used in medicine due to its therapeutic properties, including its antioxidant, anti-inflammatory, and antidiarrheal activities. Light is an important regulator of the growth, development of plants differentiation, and metabolism. Considering the influence of light on the production of phytochemicals, the aim of the present study was to evaluate production of gallic and 3,4-dihydroxybenzoic acids and amentoflavone in A. othonianum seedlings grown in vitro exposure to white, blue, green, red, and yellow light. The seedlings were evaluated with respect to the length of the aerial parts and the number of leaves, at 0, 20, and 40 days of treatment. The fresh and dry weights of the aerial parts and the levels of phenolic acid and biflavonoid were evaluated at 40 days via high-performance liquid chromatography with a diode array detector (HPLC-DAD). Regardless of the light wavelength used for the growth, the largest length of the aerial parts (5.54 cm) and an increase in the number of leaves (2.86-fold) were observed at 40 days. The largest accumulations of fresh weight (325.5 mg and 335.1 mg per seedling) and dry weight (83.3 mg and 84.5 mg per seedling) were observed in seedlings grown under red and yellow light, respectively. Relatively higher levels of gallic acid (0.66 mg.g -1 dry weight) and amentoflavone (1.41 mg.g -1 dry weight) were found in seedlings grown under blue light. In contrast, the 3,4-dihydroxybenzoic acid levels of the seedlings under red light increased (8.22 mg.g -1 dry weight).

“…There are many reports of increases in secondary metabolites under high light intensities. For example, this has been reported to occur in tea (Wang et al, 2012). Ghasemzadeh et al (2010) reported that light intensity, with subsequent changes in plant morphology and physiological characteristics, affected the synthesis of the medicinal component of herbs.…”

Premna serratifolia has been used to treat inflammatory disorders because it was believed to have antioxidant properties. However, scientific research on this species is currently lacking. This work assesses the antioxidant activity of P. serratifolia in relation to light intensity and temperature. Harvesting time significantly influenced the antioxidant activities in P. serratifolia leaves; the highest 1,1-diphenyl-2-picryl-hydrazil (DPPH) free radical scavenging activity and lowest flavonoid and phenolic contents were observed at 9 am. The opposite trend was observed at 12 noon. Temperature had a significant influence on the DPPH free radical scavenging activity and phenolic content. The DPPH antioxidant activity was negatively correlated with light intensity. The results of this study indicated that harvesting time of P. serratifolia leaves should be tailored according to the preferred antioxidant activity.
