OBJECTIVE There has been a growing interest in finding plants with biological active ingredients for medicinal application. MATERIALS AND METHODS Three colors of petals of Althaea officinalis (A. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. RESULTS The reddish pink flowers of A. officinalis have more antioxidan...

The flower is the reproductive organ of tea plant, while it also processed into different kinds products and thus great significance to be utilized. In this study, non-volatile secondary metabolites in internal external petals white, white pink, pink flowers were studied using a widely targeted metabolomics method with ultra-high liquid chromatography–tandem mass spectrometry (UPLC-MS/MS). A to...

Abstract Gazania (L.) is one of wild ornamental plant which has special architectures. It a small genus 16 species, belonging to the family Asteraceae (Formerly: Compositae). low-growing perennial herb, grow in clumps and can also form dense carpets covering large areas. multiple genera species with mutli-petals colors. The chlorophyll pigmentation was measured leaves petals these specimens sho...

W1, W3, W4, and Wm genes control flower color, whereas T and Td genes control pubescence color in soybean. W1, W3, Wm, and T are presumed to encode flavonoid 3'5'-hydroxylase (EC 1.14.13.88), dihydroflavonol 4-reductase (EC 1.1.1.219), flavonol synthase (EC 1.14.11.23), and flavonoid 3'-hydroxylase (EC 1.14.13.21), respectively. The objective of this study was to determine the structure of the ...

The difference in size, shape, and chemical cues of leaves and flowers display the underlying genetic makeup and their interactions with the environment. The need to understand the molecular signatures of these fragile plant surfaces is illustrated with a model plant, Madagascar periwinkle (Catharanthus roseus (L.) G. Don). Flat, thin layer chromatographic imprints of leaves/petals were imaged ...

Molecular mechanisms governing development of the male reproductive organs of flowers, the anthers, are largely unknown. In this article, we report on the investigation of the molecular basis of a mutation involving the expression of a gene encoding the flavonoid biosynthesis enzyme chalcone flavanone isomerase (CHI) in anthers of petunia. In petunia, the gene Po regulates the expression of CHI...

BACKGROUND Variegation in flower color is commonly observed in many plant species and also occurs on ornamental peaches (Prunus persica f. versicolor [Sieb.] Voss). Variegated plants are highly valuable in the floricultural market. To gain a global perspective on genes differentially expressed in variegated peach flowers, we performed large-scale transcriptome sequencing of white and red petals...

Abstract Background Rosa damascena is an aromatic rose species, which cultivated for its essential oil, and widely used in perfume, cosmetic, pharmaceutical, food industries the world. This experiment was conducted to evaluate oil morphological variations of 26 Damask genotypes. For this purpose, effect harvest time, i.e., early morning or evening, sampling type, fresh dried petals, on content ...
