“…Our method provides more detailed information because it allows changes in production of single anthocyanins to be measured. Previous studies have shown an increase in total anthocyanin level with moderate temperature decline for vegetative structures (Christie et al 1994, Kleinhenz et al 2003, Rabino and Mancinelli 1986, Shichijo et al 1993), flowers (Biran and Halevy 1974, Biran et al 1973, Ratsek 1944, Shaked‐Sachray et al 2002, Shvarts et al 1997a, 1997b) and fruits (Faragher 1983, Zhang et al 1997). Our data show that in P. lanceolata flowers, levels of multiple anthocyanins increase with a moderate temperature decline.…”

Flower color in the weedy perennial Plantago lanceolata is phenotypically plastic. Darker flowers are produced at cooler ambient temperatures, and circumstantial evidence suggests that this is adaptive. The goal of this project was to investigate the chemical basis for the color plasticity. To test the hypothesis that increased anthocyanin production at low temperatures underlies the plasticity, extracts of P. lanceolata flowers produced at warm and cool temperatures were analyzed using UV/visible spectrophotometry coupled with mass spectrometry. Mass spectrometry allowed us to compare relative abundances of individual anthocyanins. Seventeen anthocyanins, derived from both cyanidin and delphinidin branches of the anthocyanin biosynthetic pathway, were detected. Most of these significantly increased in abundance under cool conditions. Genotypes differed significantly in anthocyanin levels and in their sensitivity to temperature change. Genotypes that showed greater floral color plasticity tended to show also greater temperature sensitivity with respect to anthocyanin production. Data suggest that the temperature regulation of the anthocyanin biosynthetic pathway occurs both upstream and downstream of the divergence of the cyanidin and delphinidin branches. The degree of temperature sensitivity, i.e. phenotypic plasticity, appears to be controlled downstream, whereas the overall temperature effect appears to be controlled upstream.

The effect of pretreatments and soaking conditions on the color quality of rose liqueur was investigated. Results show that (1) most of the anthocyanin in rose petals was dissolved within 48 h of soaking; (2) a longer soaking time led to a lower color quality due to browning ; (3) a base spirit at lower ethanol content extracted more anthocyanin and also resulted in more browning; (4) 50C air‐drying to 20% water content retained 90% of anthocyanins in rose petals; and (5) the soaking of dried petals in the base spirit yielded a product with less browning as compared with that of fresh petals. The process for making rose liqueur with the best color quality was found to be by soaking dried rose petals at a 1:10 ratio (rose petal : ethanol, w/w) in a base spirit containing 30–35% ethanol added with 0.6–0.8% citric acid for 24 h, then diluting the extract to 16% ethanol content. PRACTICAL APPLICATIONS This study provides an adequate process for the making of rose liqueur. Pre‐dehydration treatment can be applied on the raw material in the making of various anthocyanin‐containing beverages to improve the color quality. Findings in regard to the effect of ethanol concentration on anthocyanin extraction and the color stability of the product can also be valuable references to wine industry.

“…This color and pattern were found in the original, non-tissue cultured plant. Several factors can affect flower color and size, including temperature, light, and CO 2 concentration (Biran et al 1973). This would account for differences in flower color between clones, but not flowers on the same plant.…”

Epigenetic variation in tissue cultured Gaura lindheimeri

High levels of variability were observed in tissue cultured Gaura lindheimeri genotypes when flowered in situ. Tissue culture treatments for chromosome doubling (colchicine: 0, 0.25, 1.25 mM; trifluralin: 0, 15, 30 mM) were all highly variable for morphological traits. Experiment No. 1 tested the tissue culture protocols used. In the first control (C1), plantlets were subcultured continuously. Nodes were excised and placed on solid medium for the second control (C2). In the third control (C3), nodes were excised and put in liquid medium for 24 h at room temperature. The fourth control (C4) was the same as the third control except liquid cultures were moved to 48C for 48 h after treatment at room temperature. Experiment No. 2 examined the stability of the variation. Representative plants with different traits were selected for clonal propagation and grown in a replicated trial in the greenhouse. Several morphological traits (flower size, leaf length:width ratios, petal length:width ratios, and flower color) were measured. All of the controls had as much variability as the treated plants. Flower size of the first flower for plant number 01G-02 was significantly different in C1 compared with C3, but not with C2 and C4. Plant number 443-1 (white) was more stable in the replicated trial for the flower size than plant number 01G-02 (pink). All traits measured for plant number 01G-02 were unstable; most flower colors and patterns reverted back to the original color of the non-tissue cultured plants. The somaclonal variation observed was epigenetic in nature, indicating changes in DNA methylation.
