A new p-hydroxyphenylacetyl flavonoid, diosmetin 7-(6''-O-p-hydroxyphenylacetyl)-O-beta-d-glucopyranoside (1), was isolated from the flowers of Chrysanthemum morifolium Ramat. 'huaiju' cv. nov. (Compositae), together with five known flavonoids, luteolin (2), diosmetin (3), diosmetin 7-O-beta-d-glucopyranoside (4), diosmin (5), and scolimoside (6), and four known caffeoylquinic acid derivatives,...

Chrysanthemum morifolium Ramat is one of the four major cut flowers in world. Pht1 family focus on uptake and transport phosphate plants. In our previous studies, CmPht1;2 overexpression line (Oe1) had higher contents both roots shoots, its root development was significantly enhanced than wild type (WT) at low phosphorus conditions chrysanthemum. Metabolomics analysis showed that several metabo...

The coccinellid predator Coleomegilla maculata (DeGeer) is found throughout the central and eastern United States and is a potential biological control agent for interiorscapes. Currently, the systemic insecticide imidacloprid is widely used in interiorscape and landscape integrated pest management. Effects of imidacloprid on the Þtness and behavior of C. maculata were examined by conÞning grou...

Fifteen pentacyclic triterpene diols and triols, consisting of: six taraxastanes, faradiol (1), heliantriol B0 (2), heliantriol C (3), 22a-methoxyfaradiol (4), arnidiol (5), and faradiol a-epoxide (6); five oleananes, maniladiol (7), erythrodiol (8), longispinogenin (9), coflodiol (10), and heliantriol A1 (11); two ursanes, brein (12) and uvaol (13); and two lupanes, calenduladiol (14) and heli...

The antioxidant function of edible flowers have attracted increasing interest. However, information is lacking on the impact of edible flowers on oxidative injury including hypoxia-re-oxygenation and hyperlipidemia. The antioxidant activities of aqueous extracts from 12 Chinese edible flowers were assessed in four different antioxidant models, including total antioxidant capacity (TAC), oxygen ...

Although a number of plant carotenoid cleavage dioxygenase (CCD) genes have been functionally characterized in different plant species, little is known about the biochemical role and enzymatic activities of members of the subclass 4 (CCD4). To gain insight into their biological function, CCD4 genes were isolated from apple (Malus x domestica, MdCCD4), chrysanthemum (Chrysanthemum x morifolium, ...

Abstract Flower shape is a key trait of ornamental and commercial importance in breeding programs for chrysanthemum ( Chrysanthemum morifolium Ramat.). Understanding the genetic basis phenotypic variation seen inflorescence-related traits will contribute to improvement development new varieties. In this study, we investigated determinants inflorescence using an F 1 segregating population derive...

Chrysanthemum morifolium propagation through stem cutting produces weak plants that show delayed anthesis above 20 °C and a reduced flower diameter. Therefore, in this study chrysanthemum plantlets were produced somatic embryogenic from calli to exploit the somaclonal variation for their improvement. Various explants variety Dante yellow cultured on Linsmaier Skoog (LS) medium with various conc...
