The flowers of pagoda tree (Sophora japonica L.) are white, which limited its ornamental value and caused few researches on flower color anthocyanin accumulation. A pink mutant (PM) was discovered, provided an opportunity to investigate biosynthesis in flowers. In this study, the flavone/flavonol contents petals PM wild type (WT; white flower) were measured. content total anthocyanins significa...

Lycoris longituba is one of the species belonging to the Amaryllidaceae family. Despite its limited distribution, endemic to central eastern China, this species displays an exceptionally wide diversity of flower colors from purple, red, orange, to yellow, in nature. We study the natural variation of floral color in L. longituba by testing the components of water-soluble vacuolar pigments--antho...

The model basal eudicot plant California poppy (Eschscholzia californica Cham.) typically has intense yellow to orange petals and orange pollen due to pigmentation by carotenoids. Flower color variants ranging from white to yellow and orange are common. We analyzed flower color inheritance in a diverse range of white and yellow color variants with reduced carotenoid content. The inheritance of ...

The curvature of citrus petals was studied, using petals implanted in an agar-sucrose medium. Applications of indoleacetic acid and p-chlorophenoxyisobutyric acid and determinations of endogenous auxins indicate that the bending of citrus petals is an auxin-mediated process.

Genetic engineering of roses and other plants of floricultural importance to give them a truly blue petal color is arguably one of the holy grails of plant biotechnology. Toward this goal, bluish carnations and roses were previously engineered by establishing an exclusive accumulation of delphinidin (Dp)-type anthocyanins in their petals via the heterologous expression of a flavonoid 3',5'-hydr...

Tree peony (Paeonia suffruticosa Andrews) is a very famous traditional ornamental plant in China. P. delavayi is a species endemic to Southwest China that has aroused great interest from researchers as a precious genetic resource for flower color breeding. However, the current understanding of the molecular mechanisms of flower pigmentation in this plant is limited, hindering the genetic engine...

The article elucidates the possibility of using yellow dye, obtained from saffron petals (Carthamus Tinctorius L.) in food industry. This powdered added to yoghurt concentrations 0.3 – 0.4%, addition its color, gives samples a light aroma flowers and demonstrates high stability during storage at 4° C. for 28 days. values chromatic coordinates, L *, b yogurt did not undergo considerable changes ...

This study used three-dimensional (3D) micro-computed tomography (μCT) imaging to examine petal form variation in a hybrid cross of Sinningia speciosa between a cultivar with actinomorphic flowers and a variety with zygomorphic flowers. The major objectives were to determine the genotype-phenotype associations between the petal form variation and CYCLOIDEA2-like alleles in S. speciosa (SsCYC) a...

We used comparative developmental morphology to study the evolution of nonpapilionaceous corollas in the amorphoid clade of the tribe Amorpheae (Papilionoideae). This clade consists of five genera in which there are no papilionaceous corollas (five petals differentiated into one banner, two wing, and two keel petals). We studied the ontogenies of three nonpapilionaceous forms: corollas consisti...
