Anthocyanin, antioxidant activity and stress-induced gene expression in high CO2-treated table grapes stored at low temperature

The Upregulation of NtAN2 Expression at Low Temperature is Required for Anthocyanin Accumulation in Juvenile Leaves of Lc-transgenic Tobacco (Nicotiana tabacum L.)

“…It is believed that the biosynthesis of anthocyanin in various plants is enhanced by low temperature (Christie et al, 1994;Leyva et al, 1995;Shvarts et al, 1997;Romero et al, 2008;Steyn et al, 2009). Similarly, we also found the Lc-transgenic tobacco lines exhibited purple pigmentation in young leaves at low temperature ( Fig.…”

Coordinated regulation of anthocyanin biosynthesis in Chinese bayberry (Myrica rubra) fruit by a R2R3 MYB transcription factor

“…Then 1 ml supernatant and 4 ml of either buffer A (0.4 M KCl, adjusted to pH 1.0 with 2 N HCl) or buffer B (1.2 N citric acid, adjusted to pH 4.5 with 0.2 M NaH 2 PO 4 ) were mixed and the absorbance at 510 and 700 nm measured. The anthocyanin content was calculated according to Romero et al (2008) using the following formula: TA = A 9 MW 9 5 9 100 9 V/e, where TA stands for total anthocyanin content (mg/100 g, as cyanidin-3-O-glucose equivalent), V for final volume (ml), and A = [A 510 nm (pH 1.0) -A 700 nm (pH 1.0) ] -[A 510 nm (pH 4.5) -A 700 nm (pH 4.5) ]. A molar absorptivity (e) of 26,900 and molecular weight (MW) of 449.2 were used according to Wrolstand et al (1982).…”

Functional analysis of differentially expressed proteins in Chinese bayberry ( Myrica rubra Sieb. et Zucc.) fruits during ripening

“…The pH of Chinese bayberry juice was measured by using a pH meter (HI221, Hanna, USA) following the manufacturer's protocol. Anthocyanin determination was performed by pH differential spectrophotometry in accordance with the method described by Romero, Teresa Sanchez-Ballesta, Maldonado, Isabel Escribano, and Merodio (2008). Three measurements for each biological replicate sample were performed.…”
