chrysanthemum indicum/proline

Proline plays a significant role in plant resistance to abiotic stresses, and its level is determined by a combination of synthesis, catabolism and transport. The primary proteins involved are Δ(1)-pyrroline-5-carboxylate synthetase (P5CS), proline dehydrogenase (PDH) and proline transporter (ProT).

Cold acclimation is necessary for chrysanthemum to achieve its genetically determined maximum freezing tolerance, but the underlying physiological and molecular mechanisms are unclear. The aim of this study was to discover whether changes in antioxidative enzymes, proline metabolism and

Various abiotic stresses downgrade the quality and productivity of chrysanthemum. A construct carrying both CcSOS1 (from Chrysanthemum crassum) and CdICE1 (from Chrysanthemum dichrum) was constitutively expressed in the chrysanthemum variety 'Jinba'. The transgenic plants were superior to the wild

Soil salinity represents a major constraint on plant growth. Here, we report that the over-expression of the Chrysanthemum crassum plasma membrane Na(+)/H(+) antiporter gene CcSOS1, driven by the CaMV 35S promoter, improved the salinity tolerance of chrysanthemum 'Jinba'. In salinity-stressed

This paper reports the first study on plant CBF transcription factors (TF) in salt and drought stress responses in Chrysanthemum lavandulifolium. A CBF homolog gene, named as ClCBF1, from C. lavandulifolium was isolated using rapid amplification of cDNA ends (RACE). The deduced peptide is comprised

OBJECTIVE To study the salt stress tolerance of Hongxinju, Huangju and F1 seedlings from orthogonal and reciprocal cross under different salt treatments. Grope for transmissibility of salt tolerance between parents and F1 seedlings, and relativity between flavone, chlorogenic acid contents and salt

OBJECTIVE To investigate hydroxyproline tolerance of Chrysanthemum morifolium plantlets included " Boju", "Huaiju", "Chuju", "Gongju" and "Hangju",and provide references basis for excellent cultivar and breeding of Ch. morifolium. METHODS Plantlets in vitro from five kinds of Ch. morifolium were

OBJECTIVE To explore the effects and mechanism of Chrysanthemum indicum on experimental ventricular remodeling induced by isoprenaline (ISO) and L-thyroxine (L-Thy). METHODS The ventricular remodeling of mice were induced by subcutaneous injection of ISO with the dosage of 2 mg/kg daily for 7 d and

Chrysanthemum lavandulifolium (Fisch. ex Trautv.) Makino is a halophyte species that belongs to the Asteraceae family, and the genus Chrysanthemum. It is one of the ancestors of C.×morifolium Ramatella. Understanding the tolerance mechanism associated with salt stress in C. lavandulifolium could

Genes of the ICE (Inducer of CBF Expression) family play a key role in cold and freezing stresses response via the CBF regulatory pathway. In this work, we identified the ICE family gene, CmICE2, from Chrysanthemum morifolium 'Jinba'. CmICE2 encodes a 451-amino acid protein with a conserved nuclear

CONCLUSIONS CmWRKY17 was induced by salinity in chrysanthemum, and it might negatively regulate salt stress in transgenic plants as a transcriptional repressor. WRKY transcription factors play roles as positive or negative regulators in response to various stresses in plants. In this study, CmWRKY17

The quality and productivity of chrysanthemum are severely compromised by various abiotic stresses. Here, we describe the isolation of CdICE1 from Chrysanthemum dichrum using RACE PCR, which shared identical nucleotide of ICE1 ORF from Chrysanthemum grandiflorum variety 'Jinba'. CdICE1 contains a

High salinity seriously affects the production of chrysanthemum, so improving the salt tolerance of chrysanthemum becomes the focus and purpose of our research. The WRKY transcription factor (TF) family is highly associated with a number of processes of abiotic stress responses. We isolated DgWRKY4

DNA cassette containing an AtDREB1A cDNA and a nos terminator, driven by a cauliflower mosaic 35S promoter, or a stress-inducible rd29A promoter, was transformed into the ground cover chrysanthemum (Dendranthema grandiflorum) 'Fall Color' genome. Compared with wild type plants, severe growth

Five intergeneric hybrids between the chrysanthemum cultivar 'Zhongshanjingui' (as female) and Ajania przewalskii (as male) were obtained with the help of embryo culture. While 'Zhongshanjingui' bears a standard anemone type flower and A. przewalskii a non-anemone type one, the inflorescence type of
